My HVAC company installed one when they tested my run capacitor and it was close to dying during my Spring checkup.

Awesome, this fixed my compressor that was struggling with startup! Pressure readings were good, but just would not turn over for more than 3 seconds. So easy too was a bonus. Thank you!!!
The two wire hard start you have in your hand has a positive temperature coefficient thermistor under that top cap. Not a potential relay. It opens and closes due to temperature rise and fall, not an electromagnet
So hypothetically if one has this on their AC Unit and they live in say the DESERT, where daytime temps are 100+, this is worse than having nothing? correct?

Awesome work son I like how you explain everything I'm learning the trade you do a lot better explaining then some of the older techs keep them coming please.
Thx. I am the proud owner of (2) 33 year old Trane condenser units - installed when the house was built. Last night the upstairs unit stopped cooling. I replaced the 3 capacitors (2 had bad readings) from my stash and got the unit running. I had heard about these Hard Start boost devices but needed to know more. This video is great. Many thanks. My situation checks several on that list. I will order one today.
@@lklpalka Hi Ed. Sorry about the slow response. Yes, this booster and my A.C. unit are working fine. I expect to get another season out of the 2 A.C. units ... fingers crossed considering their age. If you are still undecided about buying and installing one, my recommendation still holds true.
@@ApexHotShot I'm ready to install the replacement hard start kit today... same specs as original. Have a spare cap with extra 100mfd more kick on hand just in case. Repl. of oem dual-run cap didn't do much. Maybe new contactor and start kit will keep it for another year or two. Trane XL14i, just had 13th b'day but had been professionally maintained by contractor who retired. Hopeful..TY Bryan!
Thank you for all the videos that you have produced, I have learned a lot from you, and I really appreciate your knowledge, and you as a good helpful human being!
Ugh. I just spent $350 on this with 1.5 lb of Freon in my 13 year old unit. I feel like an idiot. Im a big fan of DIY but I didn't know anything about this until AFTER the work was done. I'm such a sucker. Great video.
I finally got around to installing a KickStart unit. What a difference!! Should have done it years ago!! The compressor always made a very loud 60 cycle hum when it would start but in recent years it was occasionally cutting in and out when trying to start (it's a scroll). Now, the loud hum is gone, and no more cutting in and out. Perfect! I used the Rectorseal KS1 96506, by the way. Installation was easy.
Would your ac use more electricity when it would do that? Because mine is doing that rn and I can’t find the start kit anywhere and my house is burning hot just wondering if I can have it on?
Amazing guy I’m surprised how simple video and six something that causes big trouble The way he’s playing it is simple. It’s 123. Thank you for posting this video. I’m pretty sure you save a lot of peoples money and fix many peoples problems. Thank you for posting this video.
Hi Thanks for the video, it got my Lenox Unit up and running so far...the unit itself probably went through 3 or 4 cycles after installing the kit and then I heard the compressor start instead of just humming for 5 seconds and shutting off...1st symptom was blowing hot air > Replace Capacitor (no change) ...> Install Hard Start kit and restart , after about 30 minutes the think kicked on and is still JAMMING Thanks Again ! Stay Safe Stay Cool ~
still intermittently failing with buzz when system calls for cold air but does occasionally start and cool ..any comments or ideas ? my thinking is that the thermostat and controls are good , thing is that when it does start up , it sounds like there are 100 little men in there with hammers but it does run and cool
My dear you so sweet the way you explain is nice and important. I'm watching you video every single day and l learn so many things from you thank you so much. Can you please do some video about high efficiency furnace. God bless you my dear.
Thank you! :) Glad to hear you like the videos! As you saw from my videos, my furnace is not a high efficiency one and I can't film in customers' houses.. But if I get a chance later on I'll try to film one! May God bless you and family as well!
Great simple and straight forward. I have tired the 5 2 1 on a couple of units without much success only lasting a few months (following the wiring diagram carefully). So I am going to give this one a try. Thanks again.
Love your videos! Very informative. Open Question for the HVAC Gurus... I know Start performance improvement with a 5-2-1 Hard Start Capacitor Kit is not as great on SCROLL compressors, compared to RECIPROCAL types (many Y.T. vids show reductions of Inrush Amps by as much as 45% after installing a 5-2-1 Kit - I assume these are on Reciprocal compressor units). At best, I've seen only about a 9% reduction in Inrush Amps on my Rheem 5-Ton Scroll Compressor aftter the 5-2-1 Kit was installed. Is this a normal "improvement" to see when matching the 5-2-1 Hard Start kit (biggest capacitor) to a Scroll compressor, or should I be seeing lower Inrush results than this? Install Story/DETAILS, for anyone interested: So, I just installed a CPS 5-2-1 CSRU3 Hard Start KIT in my 7YR old Rheem 5-ton SCROLL compressor/condenser unit, ( was running fine), but was slightly slower, buzzier, and metered with INRUSH Amps a bit above the specification on start-ups, recently. L.R.A. specification for this 5-Ton split unit is: 152.9 Amps. BEFORE 5-2-1 Install... Compressor "C" wire Metered INRUSH = 157.2 Amps. AFTER 5-2-1 Install... Compressor "C" wire Metered INRUSH = 156.1 Amps. Metered several "call for cooling" startups @ 150-155Amps INRUSH, AFTER Install: Best score was 147Amps INRUSH, with most starts hitting 152-155Amps. Disappointed (thinking the 5-2-1 kit was a dud), I metered INRUSH again, a day later, on a few more start-ups - I found that my INRUSH was averaging between 142-146 Amps and the compressor has a more positive start, no buzzy wind-up; lighting in home doesn't dim during start, as before. All wiring terminals checked & re-verified, good. (Same weather, thermostat settings, no other system changes since install day). Odd - I'm unsure why unit seemed to perform better the following day. Thanks for reading!
After 30 years the capacitor on my a/c got wore out and bulged at the top. I popped in a new one with the hard start kit 2 days ago. Works like a charm. Cost $40.00 bucks for the parts.
@@Elcaballo599 I got mine at an HVAC store. Plenty of them in my city. But if you're lucky, some electronics stores and hardware stores carry them too. Amazon has sellers, but they mark them up really high to cover for the shipping.
I read that a hard start kit must match your system’s tonnage and or compressor HP. So how do we choose the correct hard start kit for our system? Thank you 😊
There's a 1,2,3 ton start up and a4, 5 ton startup. Look on your a/c what tonnage it is and choose one or the other. If you live where it's hot get a 3wire kit not a two wire kit.
@@jasonpoolo3523 and still helpful to know this. Thank you for taking the time to share. I live in Texas and the three wire thing was also good to know.
You haven't heard about the "ZAP" because they never lived to tell the story...j/k...I dropped a screwdriver on one terminal and the other part hit grounded metal and it burnt the screwdriver to the terminal. I had to break it free. Definitely scared me.
Glad to hear the videos have been helpful! It won't hurt anything but there's a chance that it will prolong the life of the compressor. Back in the day most units had them installed by default but to cut costs they stopped doing that.
Great Video.. I have a brand new unit and it trips the breaker sometimes upon startup... the company that installed it told me it would not void the warranty if one was installed...
Thanks man. My compressor buzzes for a few seconds then gives up. Already replaced the capacitor. New contactor and hard start kit in the mail, hopefully I can get this fixed soon.
Awesome explanation. My run capacitor is open circuit. Now that I know it is a run capacitor thanks to you, I can just replace it. I was looking for the start kit in my unit and didn't see one, even though it's shown in the schematic. Sounds like I could easily add it and improve things a bit.
I’m just trying to understand in my head how this works....lol Compressors are very specific about what size capacitors is will use. How is it that that the 3 in 1 Supco hard start kit will work for multiple different units that require different size caps to run the compressor. It’s like a one size fits all.
It's really only the run capacitor that needs to be a specific size. The start capacitor just needs to be 'big enough'. So once it is started, the start capacitor is taken out of the circuit by a relay.
Hi Jay I have a new installed an AC unit the inside and the out side about a year ago. However, a few days ago the condenser unit capacitor failed and unable to start the compressor . I had to replace the capacitor, now working fine. The unit is 3 tone /14 seer and 45/5 capacitor. I also noticed that it doesn’t have hard start capacitor; my question is would it helps to put hard start capacitor to maintain the life of compressor and for easy start. I always watch your video. I exceedingly appreciate you for every education you provided us with. Thank you
I wish I had known this before Damien Pietak of Superior Air Systems in San Diego charged me $703 to replace mine -- that was $618 for parts plus $85 for a service call. He knew before he showed up that this was the likely problem and he went straight to it. It took him about 10 minutes to test and replace.
That happens to me twice with some plumbing issues, first I was charged a littlemore than $500 for replacing a water hose inside the house, and later above $300 for similar task outside the house, and I said never again. After that every single issue I have I google it, I watch as many video as needed and I fix it myself. Installing dishwasher, fixing plumbing issues, installing 240v circuit, adding new breakers in the electrical panel, troubleshooting AC problems, installing thermostat, installing inlet for generator, etc, etc, etc. My advice: if you feel that you can do it, then you are right. Just invest some time to learn about the topic and you will be ok.
@@brianp9054 Right! -- or at least know what's involved so you can judge whether or not the bid is fair. And by all means, get a bid in advance. And if you can, watch to make sure they don't cut corners.
OK... I need your advice about some specific things. As always, your fast reply is greatly appreciated. Facts: My current unit is a 3 ton split Bryant (20ish yr old unit) that currently starts and runs flawlessy. The condenser has a reciprocating Bristol Compressor model # H25B32QABCA. when I looked up specs it said under ELECRICAL ACCESSORIES category it lists Start Relay: GE 3ARR3*3N* (*3P*) Start Cap: 88-108/250 (145-175/250) µF/volts Run Cap: 40/370µF/volts On the fan motor it says 5 MFD / 370 The dual capacitor I have on the condenser is a Totalline P291-4054RS 440V MFD 40/5 I have ordered the 5-2-1 / 1-3 ton CSRU1 hard start kit and it says 88-108 MFD is its spec. It is NOT installed YET. I think I know the answers to all of the below issues and simply want to cross reference with a pro so I do not accidentally blow up my condenser (or whatever) so here are some... Questions: If there are no other capacitors (other than the 40/5 mfd dual) in the electrical connections area of the condenser does that mean... 1) I do NOT currently have a start capacitor installed at all? In other words, it was only considered an accessory for the unit so it was not installed and the dual cap I have is only to run the compressor and the fan but has no additional "boost" for starting? If so... 2) It isn't ABSOLUTELY NECESSARY to have a start cap or hard start kit to run a condenser? 3) Is my (soon to be installed) 5-2-1 Hard Start Kit adding / performing the function of the (currently missing) start cap? 4) The 5-2-1 is a perfect match to the compressor spec. correct? 5) Is there any other location (besides the electrical connection area) in the condenser where I might find a start cap (if it exists)? 6) I saw or read a few different places that I should install a new Dual Capacitor (especially if Dual Capacitor is out of spec) at the same time I install thenew 5-2-1 kit or the new Hard Start Kit MAY slowly damage the compressor windings. Do you know if this is true (or anything about this)?? 7) In your opinion, are American made run capacitors worth the extra money (and are they any better for the longevity of HVAC equipment?) I can buy an Eastman (foreign made) Capacitor at H Depot for $6.80 or (USA made) AmRad for $28 or Titan HD (by Packard) for $16 ish. 8) In your last message to me you said "I need to make another video where I compare the 5-2-1 and the hard start kit". I thought the 5-2-1 WAS a "hard start kit" but the way you referred to it in your message makes it sound like it isn't a hard start kit. A) Is the 5-2-1 a hard start kit? B) If not, then what is it? C) For my application, does it matter? please clarify.
Lol, this comment got spammed just for the sheer length of it. I appreciate the organized comment! I will answer them in the order asked. (to the best of my knowledge, I only have 6 years of experience so I wouldn't exactly call myself a veteran tech) 1) If you look at your condenser wiring diagram it will probably say "start capacitor *may* be factory installed. That usually means it's not factory installed. 2) No it is not absolutely necessary to have a start capacitor. Many companies stopped putting them in to save themselves a few bucks in manufacturing costs. 3) Yes 4) Yes 5) It will normally be in the electrical section where the run capacitor and contactor reside. Big black cylinder typically hard to miss.. 6) I have never heard that before. But that's not a bad idea. An out of spec run capacitor should be replaced regardless if you are putting in a start capacitor or not. 7) I don't think it matters too much but some people will claim that American made is better. The insides are pretty much the same. (You could buy two cheap ones and keep one as a spare for peace of mind) 8) Sorry for the confusion. They are both hard start kits but one has a potential relay and the other does not. I usually refer to them as start capacitor and potential relay (5-2-1) and hard start kit (no potential relay). Is that technically correct? I really don't know, that's just what I call them.
The part you missed in your explanation. Do I still hook just the 2 wires up and leave the relay connected? Mine is an older trane that has the capacitor hooked up to the relay with 3 wires RLY1097 relay
This Subco uses a Positive Temperature Coefficient Relay (as stated on their website) not a Potential Relay. Not Good! Only use Hard Start Kits that use a true Potential Relay. The RectorSeal Kickstart (2 wire) and the 5-2-1 Compressor Saver (3 wire) hard start kits use a Potential Relay. I recommend the Kickstart (it uses 2 wires that connect to the Run Capacitor - HERM and COM). But the Compressor Saver is also good (3 wires with one connecting to the common / ground on the Contactor relay). They both work the same way - the Potential Relay detects the pickup voltage (back EMF). This causes the relay to disconnect the start capacitor when the compressor reaches about 75% speed (usually less than a second). Note: Supco does have hard start kits with a Mechanical Potential Relay (Models 3W1, 3W2, & 3W3).
Thanks for the info. Our compressor was giving me some issues this year so I tried this and it worked. Hopefully we can at least get through this summer with this cheap fix.
I didn't hear you mention which terminal takes which of the black wires to Herm and Capacitor. I surmise that it doesn't matter which wire goes to which spade and that I could connect either wire to either spade, correct?

did they work?
@@lklpalka Hi Ed. Sorry about the slow response. Yes, this booster and my A.C. unit are working fine. I expect to get another season out of the 2 A.C. units ... fingers crossed considering their age. If you are still undecided about buying and installing one, my recommendation still
holds true.
@@ApexHotShot I'm ready to install the replacement hard start kit today... same specs as original. Have a spare cap with extra 100mfd more kick on hand just in case. Repl. of oem dual-run cap didn't do much. Maybe new contactor and start kit will keep it for another year or two. Trane XL14i, just had 13th b'day but had been professionally maintained by contractor who retired. Hopeful..TY Bryan!
So it doesn’t matter which wire goes to common and which wire goes to Herm?
Thanks for doing these videos. They help...
The two black wires coming from the hard start kit? You are right, it does not matter which wire goes where. Glad to hear the videos help! :)
Thank you for all the videos that you have produced, I have learned a lot from you, and I really appreciate your knowledge, and you as a good helpful human being!
Ugh. I just spent $350 on this with 1.5 lb of Freon in my 13 year old unit. I feel like an idiot. Im a big fan of DIY but I didn't know anything about this until AFTER the work was done. I'm such a sucker. Great video.
It’s called tuition
I finally got around to installing a KickStart unit. What a difference!! Should have done it years ago!!
The compressor always made a very loud 60 cycle hum when it would start but in recent years it was occasionally cutting in and out when trying to start (it's a scroll). Now, the loud hum is gone, and no more cutting in and out. Perfect!
I used the Rectorseal KS1 96506, by the way. Installation was easy.
Would your ac use more electricity when it would do that? Because mine is doing that rn and I can’t find the start kit anywhere and my house is burning hot just wondering if I can have it on?
Thank you. That was a great, easy to understand learning presentation. I'm terrible at fixing anything electrical, but this was a big help. Great job!
It actually changes the phase angle during start up, which increases start up torque. The relay will drop out once the run winding gets up to speed.
Slip
Can I put one without having all them problems?
SublimeSublime says thank you so much for being so precise and keeping it simple.
You're welcome! Thank you for watching and leaving a comment!
Amazing guy I’m surprised how simple video and six something that causes big trouble
The way he’s playing it is simple. It’s 123. Thank you for posting this video. I’m pretty sure you save a lot of peoples money and fix many peoples problems. Thank you for posting this video.
Thanks! I just replaced the 35/5 run cap on my 5-year old 3 ton Goodman, I'll be ordering this to add to it.
Great explanation. It couldn't be easier. Your local Aircon company wants 1-2 hundred bucks to install it.
im loving watching the a/c videos.
Very well explained, and I liked the research you did on all the reasons to install the Boost. Thank you for taking the time to do this video for us !
That's all I needed to know thank you for uploading your videos.
Perfect! I didn't want to make a mistake and you took that option away!
Man, you are the best!!! Thank you very much for your great job!!
Easily the best video on hard start kits hands down!!! Great job
Thank you man.
Hi Thanks for the video, it got my Lenox Unit up and running so far...the unit itself probably went through 3 or 4 cycles after installing the kit and then I heard the compressor start instead of just humming for 5 seconds and shutting off...1st symptom was blowing hot air > Replace Capacitor (no change) ...> Install Hard Start kit and restart , after about 30 minutes the think kicked on and is still JAMMING Thanks Again ! Stay Safe Stay Cool ~
mine is a 3 N 1 Start SUPCO RCO810 and needed to be persuaded in to position with some needlenose
still intermittently failing with buzz when system calls for cold air but does occasionally start and cool ..any comments or ideas ? my thinking is that the thermostat and controls are good , thing is that when it does start up , it sounds like there are 100 little men in there with hammers but it does run and cool
My dear you so sweet the way you explain is nice and important. I'm watching you video every single day and l learn so many things from you thank you so much. Can you please do some video about high efficiency furnace. God bless you my dear.
Thank you! :) Glad to hear you like the videos! As you saw from my videos, my furnace is not a high efficiency one and I can't film in customers' houses.. But if I get a chance later on I'll try to film one! May God bless you and family as well!
Great simple and straight forward. I have tired the 5 2 1 on a couple of units without much success only lasting a few months (following the wiring diagram carefully). So I am going to give this one a try. Thanks again.
Th
Love your videos! Very informative. Open Question for the HVAC Gurus...
I know Start performance improvement with a 5-2-1 Hard Start Capacitor Kit is not as great on SCROLL compressors, compared to RECIPROCAL types (many Y.T. vids show reductions of Inrush Amps by as much as 45% after installing a 5-2-1 Kit - I assume these are on Reciprocal compressor units).
At best, I've seen only about a 9% reduction in Inrush Amps on my Rheem 5-Ton Scroll Compressor aftter the 5-2-1 Kit was installed.
Is this a normal "improvement" to see when matching the 5-2-1 Hard Start kit (biggest capacitor) to a Scroll compressor, or should I be seeing lower Inrush results than this?
Install Story/DETAILS, for anyone interested:
So, I just installed a CPS 5-2-1 CSRU3 Hard Start KIT in my 7YR old Rheem 5-ton SCROLL compressor/condenser unit, ( was running fine), but was slightly slower, buzzier, and metered with INRUSH Amps a bit above the specification on start-ups, recently.
L.R.A. specification for this 5-Ton split unit is: 152.9 Amps.
BEFORE 5-2-1 Install... Compressor "C" wire Metered INRUSH = 157.2 Amps.
AFTER 5-2-1 Install... Compressor "C" wire Metered INRUSH = 156.1 Amps.
Metered several "call for cooling" startups @ 150-155Amps INRUSH, AFTER Install: Best score was 147Amps INRUSH, with most starts hitting 152-155Amps.
Disappointed (thinking the 5-2-1 kit was a dud), I metered INRUSH again, a day later, on a few more start-ups - I found that my INRUSH was averaging between 142-146 Amps and the compressor has a more positive start, no buzzy wind-up; lighting in home doesn't dim during start, as before. All wiring terminals checked & re-verified, good.
(Same weather, thermostat settings, no other system changes since install day).
Odd - I'm unsure why unit seemed to perform better the following day.
Thanks for reading!
Your such a bad ass. Thanks bro I’m going to school and chapter 10 is all about this. Thanks bro
Lol, thanks man. Good luck in class!
Could not of explained it any easier. Now I can install my two hard star kits on my units.
Hey Professor! Awesome video, as always.
Great stuff, brother. Clear and concise. Thank you for your expertise.
You my favorite technician
After 30 years the capacitor on my a/c got wore out and bulged at the top. I popped in a new one with the hard start kit 2 days ago. Works like a charm. Cost $40.00 bucks for the parts.
30 years wow.I have 26 years and just added this today.👍
Where can i order one
@@Elcaballo599
I got mine at an HVAC store. Plenty of them in my city. But if you're lucky, some electronics stores and hardware stores carry them too.
Amazon has sellers, but they mark them up really high to cover for the shipping.
I read that a hard start kit must match your system’s tonnage and or compressor HP. So how do we choose the correct hard start kit for our system? Thank you 😊
There's a 1,2,3 ton start up and a4, 5 ton startup. Look on your a/c what tonnage it is and choose one or the other. If you live where it's hot get a 3wire kit not a two wire kit.
Sorry just saw how old your comment was
@@jasonpoolo3523 and still helpful to know this. Thank you for taking the time to share. I live in Texas and the three wire thing was also good to know.
Thank you man i've been watching you for a long time.
You're welcome! Thank you for being a long time subscriber!
I love all of your AC videos.
CAUTION HOME OWNER DISCHARGE.. THE CAP AT THE TERMINALS. BEFORE TOUCHING IT BARE HANDS...ZAP.
How to discharge: take a screw driver and bridge it from common to herm and then common to fan.
I have not seen or heard - died by the Discharge of these capacitors. It hurts a little bit, but you will not die from it....
You haven't heard about the "ZAP" because they never lived to tell the story...j/k...I dropped a screwdriver on one terminal and the other part hit grounded metal and it burnt the screwdriver to the terminal. I had to break it free. Definitely scared me.
@@thembones12it has 240volts smarty
Excellent teacher.
Excellent video.
Thanks buddy. Simple installation
So would you put one on a brand new unit or one that is 2 - 4 years old. Love your channel. You gave me some good advice many of times on here 🤜🏾
Glad to hear the videos have been helpful! It won't hurt anything but there's a chance that it will prolong the life of the compressor. Back in the day most units had them installed by default but to cut costs they stopped doing that.
You're a great teacher man, I wish to have your knowledge, I'm going learn now, thanks a lot and hope to see more videos with mechanical stuff.
Great Video.. I have a brand new unit and it trips the breaker sometimes upon startup... the company that installed it told me it would not void the warranty if one was installed...
Thanks man. My compressor buzzes for a few seconds then gives up. Already replaced the capacitor. New contactor and hard start kit in the mail, hopefully I can get this fixed soon.
Thanks for the refresher
FYI those subco caps are not good! Love the channel!
A contractor used by a neighbor wants $300 to do this. The part costs $20, it took me 10 minutes. Think I'll take the rest of the day off!!
That’s good. HVAC mechanical is like auto mechanic. They charge you a leg for repairs, but if you can do it, you just pay parts! 😀
It cost a lot of money to put a van on the road. Typically around $1,500-$2,000 a day. They are not charging $300 for no reason.
Awesome explanation. My run capacitor is open circuit. Now that I know it is a run capacitor thanks to you, I can just replace it. I was looking for the start kit in my unit and didn't see one, even though it's shown in the schematic. Sounds like I could easily add it and improve things a bit.
Thank you for this awesome video sure helped getting my ac up and running
I would like a video about sizing a hard start capacitor to an existing run capacitor.
I’m just trying to understand in my head how this works....lol
Compressors are very specific about what size capacitors is will use. How is it that that the 3 in 1 Supco hard start kit will work for multiple different units that require different size caps to run the compressor. It’s like a one size fits all.
It's really only the run capacitor that needs to be a specific size. The start capacitor just needs to be 'big enough'. So once it is started, the start capacitor is taken out of the circuit by a relay.
You're the goat, thank you!
I like this videos from him, they are very educational
Hi Jay
I have a new installed an AC unit the inside and the out side about a year ago. However, a few days ago the condenser unit capacitor failed and unable to start the compressor . I had to replace the capacitor, now working fine. The unit is 3 tone /14 seer and 45/5 capacitor. I also noticed that it doesn’t have hard start capacitor; my question is would it helps to put hard start capacitor to maintain the life of compressor and for easy start. I always watch your video. I exceedingly appreciate you for every education you provided us with.
Thank you
Very precise straight to the point
You made look easier bro your the men
I wish I had known this before Damien Pietak of Superior Air Systems in San Diego charged me $703 to replace mine -- that was $618 for parts plus $85 for a service call. He knew before he showed up that this was the likely problem and he went straight to it. It took him about 10 minutes to test and replace.
That happens to me twice with some plumbing issues, first I was charged a littlemore than $500 for replacing a water hose inside the house, and later above $300 for similar task outside the house, and I said never again. After that every single issue I have I google it, I watch as many video as needed and I fix it myself. Installing dishwasher, fixing plumbing issues, installing 240v circuit, adding new breakers in the electrical panel, troubleshooting AC problems, installing thermostat, installing inlet for generator, etc, etc, etc. My advice: if you feel that you can do it, then you are right. Just invest some time to learn about the topic and you will be ok.
@@brianp9054 Right! -- or at least know what's involved so you can judge whether or not the bid is fair. And by all means, get a bid in advance. And if you can, watch to make sure they don't cut corners.
Thank you Bro .... that was big help you save my weekend very well explained
Glad to hear the video/s saved the day! Stay cool! ;)
Very good information very easy to install
OK... I need your advice about some specific things. As always, your fast reply is greatly appreciated.
Facts:
My current unit is a 3 ton split Bryant (20ish yr old unit) that currently starts and runs flawlessy. The condenser has a reciprocating Bristol Compressor model # H25B32QABCA. when I looked up specs it said under ELECRICAL ACCESSORIES category it lists
Start Relay: GE 3ARR3*3N* (*3P*)
Start Cap: 88-108/250 (145-175/250) µF/volts
Run Cap: 40/370µF/volts
On the fan motor it says 5 MFD / 370
The dual capacitor I have on the condenser is a Totalline P291-4054RS 440V MFD 40/5
I have ordered the 5-2-1 / 1-3 ton CSRU1 hard start kit and it says 88-108 MFD is its spec. It is NOT installed YET.
I think I know the answers to all of the below issues and simply want to cross reference with a pro so I do not accidentally blow up my condenser (or whatever) so here are some...
Questions:
If there are no other capacitors (other than the 40/5 mfd dual) in the electrical connections area of the condenser does that mean...
1) I do NOT currently have a start capacitor installed at all? In other words, it was only considered an accessory for the unit so it was not installed and the dual cap I have is only to run the compressor and the fan but has no additional "boost" for starting?
If so...
2) It isn't ABSOLUTELY NECESSARY to have a start cap or hard start kit to run a condenser?
3) Is my (soon to be installed) 5-2-1 Hard Start Kit adding / performing the function of the (currently missing) start cap?
4) The 5-2-1 is a perfect match to the compressor spec. correct?
5) Is there any other location (besides the electrical connection area) in the condenser where I might find a start cap (if it exists)?
6) I saw or read a few different places that I should install a new Dual Capacitor (especially if Dual Capacitor is out of spec) at the same time I install thenew 5-2-1 kit or the new Hard Start Kit MAY slowly damage the compressor windings. Do you know if this is true (or anything about this)??
7) In your opinion, are American made run capacitors worth the extra money (and are they any better for the longevity of HVAC equipment?) I can buy an Eastman (foreign made) Capacitor at H Depot for $6.80 or (USA made) AmRad for $28 or Titan HD (by Packard) for $16 ish.
8) In your last message to me you said "I need to make another video where I compare the 5-2-1 and the hard start kit". I thought the 5-2-1 WAS a "hard start kit" but the way you referred to it in your message makes it sound like it isn't a hard start kit. A) Is the 5-2-1 a hard start kit? B) If not, then what is it? C) For my application, does it matter? please clarify.
Lol, this comment got spammed just for the sheer length of it. I appreciate the organized comment! I will answer them in the order asked. (to the best of my knowledge, I only have 6 years of experience so I wouldn't exactly call myself a veteran tech)
1) If you look at your condenser wiring diagram it will probably say "start capacitor *may* be factory installed. That usually means it's not factory installed.
2) No it is not absolutely necessary to have a start capacitor. Many companies stopped putting them in to save themselves a few bucks in manufacturing costs.
3) Yes
4) Yes
5) It will normally be in the electrical section where the run capacitor and contactor reside. Big black cylinder typically hard to miss..
6) I have never heard that before. But that's not a bad idea. An out of spec run capacitor should be replaced regardless if you are putting in a start capacitor or not.
7) I don't think it matters too much but some people will claim that American made is better. The insides are pretty much the same. (You could buy two cheap ones and keep one as a spare for peace of mind)
8) Sorry for the confusion. They are both hard start kits but one has a potential relay and the other does not. I usually refer to them as start capacitor and potential relay (5-2-1) and hard start kit (no potential relay). Is that technically correct? I really don't know, that's just what I call them.
You are awesome
Saved me a bunch! Thank you!
Great video brother, I wish you were my instructor.
Thank you Jay, you're the Best HVAC Instructor
Dan HVAC ATL 👍
Thanks for your help!
That was very good information thanks for that so I will have to take out the start capacitor and just install this hard start on com and herm
The part you missed in your explanation. Do I still hook just the 2 wires up and leave the relay connected? Mine is an older trane that has the capacitor hooked up to the relay with 3 wires RLY1097 relay
Great video would you recommend putting a 5-2-1 hard start on 2.5 ac scroll Compressor that doesn’t have one
Excellent vid ... Explained very well as all of your vids have been so far ...
This Subco uses a Positive Temperature Coefficient Relay (as stated on their website) not a Potential Relay. Not Good! Only use Hard Start Kits that use a true Potential Relay. The RectorSeal Kickstart (2 wire) and the 5-2-1 Compressor Saver (3 wire) hard start kits use a Potential Relay. I recommend the Kickstart (it uses 2 wires that connect to the Run Capacitor - HERM and COM). But the Compressor Saver is also good (3 wires with one connecting to the common / ground on the Contactor relay). They both work the same way - the Potential Relay detects the pickup voltage (back EMF). This causes the relay to disconnect the start capacitor when the compressor reaches about 75% speed (usually less than a second). Note: Supco does have hard start kits with a Mechanical Potential Relay (Models 3W1, 3W2, & 3W3).
Crystal clear my friend
Like your clip !
Thanks for the info. Our compressor was giving me some issues this year so I tried this and it worked. Hopefully we can at least get through this summer with this cheap fix.
Might even get a couple years out of it! :) Stay cool, thank you for commenting!
Thank you very helpful
Great video very helpful keep up the good work 👍👍
I didn't hear you mention which terminal takes which of the black wires to Herm and Capacitor. I surmise that it doesn't matter which wire goes to which spade and that I could connect either wire to either spade, correct?
Thanks brotha.. your videos are the best
Thank you sir for taking your time and posting your helping videos, ordered my subco hard start today
Glad I could help! Thank you for leaving a comment!
Can you leave the 5-2-1 start relay connected and ADD. The booster ? Or you 5-2-1 relay should be removed prior?
The relay should be removed if you will be putting in the 2-wire hard start kit. Or at least disconnected.
Great video for beginners. Thanks!
Only thing I’d add is do the wires matter or can you use the two interchangeable
Good advices!!!👏👏👏👍👍👍🙌🙌🙌🙏🙏🙏👌👌👌
So, If you were to install in your unit, you would remove the relay and hard start, then just wire in the new hard start kit to the run cap?
Yes, if I were to put in the SPP6, I would take out the old start capacitor and relay.
Thank you soooooooooooo much !!!!!!!!
