The startup? We haven't seen any our air conditioners units with a quieter startup. And certainly quieter than whatever else it is replacing. Or did you mean the furnace... all ours are pretty quiet also... and the one at Ryan's house in the video is completely silent.
Nicki, is the unit on the ground or mounted to your foundation? Also, what kind of noise is it making during start up? Is it a rattling sound coming from the pipes, is it the unit making noise outside? The 2 of us that do these videos both have this unit at our homes and we don't have any major noise issues at startup.
I should have been more exact. My unit is the loudest than the two installers have heard that came out to help, it is the condenser and the fan motor. Unfortunately, I do not have the Infinity, and I am sure I would sleep like a baby with an Infinity. Thank you though for your reply.
Absolutely. You had us thinking you had this unit installed. If your unit is under warranty, the fan motor could be replaced if it is that noisy. If the motor is making that much noise, maybe it would be worthwhile to have the motor replaced, for the sake of rest! Good luck!
No, good you asked, I don't want anyone to not buy Infinity because of a misunderstanding. I added a sentence for those who only read the first posting.

Our Carrier and Bryant distributorship is based in urban and suburban areas so we don't experience much of what you are describing. We offer local dealers tons of hands-on training in our labs so they know what they are doing with the furnaces, inverters, and controls. In fact, when a new product is released, such as the 26 SEER inverter from Carrier/Bryant last year, we require the dealers to be trained prior to being allowed to purchase. We didn't realize that rural places were having such a hard time with quality installations.
I hear you bro. As a tech I have never been a fan of any of the Infinity systems. They are simply more trouble than they are worth. All that software and ECM technology with a communicating system is just too vulnerable to lighting strikes ,power surges and brownouts. And we have also had the same problem with cabinet sweating.
You can standard 24vac thermostats like nest or ecobee on this Infinity system, however it will dumb it down pretty good so there would be no reason to use those stats. For example, this is a 5-stage A/C, but if you wire a regular stat to it will only use stages 2 and 5 since ecobee and nest can only control a maximum of 2 stages.
This unit was a 3 ton. It's published sound data is 56 dbA on 1st stage and 71 on 5th stage. You can find the info on page 5 of the "product data" book at carrier.hvacpartners.com/products/detail/24VNA9. If you are an acoustical engineer, we will also point out that the same book as octave band ratings, which you will find more useful than just the rated dbA.
For those unfamiliar with sound power levels, the higher the dbA, the louder the sound. An entry level condensing unit is often 74 to 79 dbA. The scale is not liner, though. Every increase of 3 dbA is a doubling of the sound. So a rating of 76 is 4 times as loud as the 71 rating on this unit at 5th stage.
Reliability is good in general. Is there a specific motor in the system you are referring to? Like all systems, it has 4 motors. ECM technology for the blower, the inducer, and the condenser motors is very well established. For the compressor, it is a little newer...past decade or so for residential systems.
It's ECM technology. Which means that it is vulnerable to power surges and brownouts. I have replaced many inverters on these machines. If you are looking for more reliability then go with a 2 speed condenser instead of the variable speed. And stay away from the Infinity systems. That digital communication system is completely unnecessary. It has way more problems than benefits.
Yes it does. That is exactly how it works. All staging is automatic. However, in this video we forced it into the highest stage so we could illustrate the maximum sound level.
Any advice you have for working on these or problems that you’ve seen so far that I should look out for? Just did my first service call on one today but luckily it was just a communication error
it takes more than 30s to ramp up and don't konw how long the ramp down is . just image how long will be wasted during a defeost cycle. carrier , just a beginner at varible speed unite . their vrf and varible speed mini split are made by Toshiba and midea.
This particular unit (24VNA9/25VNA8) is the little brother to Carrier's first variable speed inverter (25VNA0) designed for traditional ducted systems which are common in the US. That unit came came out in 2011 so 8 years is longer than almost any of their competitors. True that inverters have been used in ductless mini-splits and VRF for a longer time frame.
Carrier's VRF is made by TOSHIBA-Carrier, which is a jointly owned venture between the two companies. They also make the rotary compressors used in the 24VNA9 units highlighted in this video.
What waste during a defrost cycle? Unlike traditional ducted heat pumps, the heat pump version (25VNA8) of the unit in this video uses sensors to determine when defrost control is actually needed instead of just using a timer.
Yes it is possible. However the specific A/C unit in this video would be dumbed down from a 5-stage Infinity to a 2-stage if you do not put it with a communicating Infinity furnace. In your scenario, we might recommend taking a look at the GREE FLEXX air conditioner to pair with your furnace.
That was not a setting, nor was it the maximum. That was the actual temperature in the duct. Normally there is not a duct sensor reading, but in the case since it was an Infinity zoning system, there was an optional leaving air temp sensor installed. The video was only on that screen for 30 seconds, but it started at 62 and went up to 63. If we continued watching it, it would have climbed up over 100. Since we shot the furnace video sequence right after the A/C sequence... and we forced the system into maximum cooling capacity... the duct was pretty cold to start... probably high 40s or low 50s, so it takes some time for the furnace to heat that metal up.
For this particular unit, the compressor and condenser fan are variable speed. However, they operate to provide 5 discrete stages of BTU/h capacities. At any moment, 1 of 5 stages is requested by the Infinity wall control. Then the outdoor unit ramps the speed up or down to get the specific BTU/h needed for that requested stage. If the speeds were 5 fixed speeds, then the BTU/h output would vary as the outdoor weather conditions varied.
@@RB-hl3ux It is half true. We are a distributor of both Carrier and Bryant system in Illinois and Indiana. There are some differences on occasion, but for most models/tiers, they are essentially the same. The cost, however, is not less for Bryant residential systems than Carrier residential systems. The equipment costs the dealer the same to buy it from our distributorship. With that said, dealers charge consumers different amounts based on their own costs (how much they pay their techs, how expensive their building rent is, the level of craftmanship they have when doing their sheetmetal and piping work, etc.). So perhaps in your local town, the Bryant dealer may quote you a price that is lower. However, on a national average, they are the same. BTW - choosing a contractor that does excellent installation work is more important than choosing the brand of equipment.
Is tempstar as good as this one? I'm looking to change out the tempstar, but now I'm confused as to which one. I want one with air handler that is much quieter. I want it wisper quiet 4 ton Seer 14. Which one which one? Please hurry responding because I have to make up my mind as to which brand I'm going to pick. I thought Tempstar was quiet.
If you want whisper quiet you need one of these 19 seer 5 speed condensers. You will not get that in any single stage 14 seer unit. We do not deal with tempstar specifically, but we do deal with ICP. ICP does make one of these DC drive condensers. We even have a video on it somewhere.
@@dmana3172 If you check out Carrier's website, you will see comparisons of all different units. Use that tool to find the right unit for your home. If budget doesn't play a role, but you want comfort and quiet, always go with the "Best" option.
question? Does altering the cfm through the stat or dip switches, lets say standard 350cfm/ton to 400cfm/ton, mess with the staging and dehumidification ability?
No, it does not alert the staging sequence. Yes, it does affect the dehumidification. To use the dehum features, leave the A/C airflow setting on "Comfort" and do not increase it to EFF325, EFF350, or MAX.
its quiet outside OK, what I want is a QUIET interior blower fan.. this old blower type is either set up wrong like they put an angle or turn right away cuz you hear the wind hitting something and its loud, no motor noise, belt noise no vibrations, squealing none of that, its that barrel blower grabbing the air its LOUD, I want a quiet blade style.. that variable speed is energy saver, specially if you have zones and you warm those up where you don't use em, then warm up zones like bedrooms to warm until you go to bed, its all done in the thermostat so an hour before bed you automatically have it cool it down to your comfy temp.. I don't cool where I do not use, not as much anyway, I keep my place at 78 in the summer, 80 in the living room, then my bedroom 77 when I sleep, in the south its like that, you acclimate and anything under 78 is cold, you don't do 72, no way, you step outside to 114 and it's too much.. down shot is that anything under say 77-78 and you get cold, no jokes, so if it drops to 74 my heater comes on, 76 is too cold for me, even with jammies on, Mena I do at times when its right there I hack it instead of turning the heat on, sweaters so forth, but if its 64 outside, and its 72 inside? heats coming on, just for a bit then its good for along time, but if its 40 outside and its been 40 fora few days, yea heat comes on regular like and I go for comfort zone, 78-80.. I hate when stores have to down to like 74 or so, freezin man! most are good they try to please everyone so they split it down the middle... snowboarders live at 72-73, locals live at 78-80, so they shoot for like 75-76, which is doable... odd but you can feel a few degrees down south, yup... until it's over like 100, then it's like is it 100 or 105, but at 107 you know it, then when its over 112? yup you know that too... odd its right around 112-114 where you get burnt on door handles, 98 if its a chrome door handle... "remove your fingerprints today" also if you let like 100+ shine through your windshield and onto your steering wheel, it will burn you when you grab it, you learn, window cover on the OUTSIDE of your window, they have special types, then a cover over steering wheel, hale i have all teh shade spots sorted where I am and I will walk a quarter mile to get on, you kidding me? I see people in 118 degree heat park windshield into the sun, no shade blocker, then get in, fire it up, turn AC on and go.. FUGG THAT! you see melted dashboards now and then, specially at wrecking yard and the dump.. time of day and shade spots is the only way to survive in the southwest...
We are not sure what you are trying to say or trying to ask us. It seems like you were using voice recognition and started rambling on conversation style. If there is something we can help answer for you, let us know... in 50 words or less LOL.
BTW - the indoor blower in this video is super quiet. And this house does have a zone damper system and Ryan does normally set the cooling for 77 degrees in the summer.
The a/c was only in stage 3 when you said it was in stage 5. When you ended the video it ramped itself up to stage 4 and not all the way up to stage 5.
To add some clarity, I think I know what Justin means. I re-watched this about a year ago when someone else asked and luckily I saved my notes... For the outdoor view, look at minute 2:27 of the video and that is when the compressor starts ramping up. Then look at 3:48 when we cut away on the edit to start talking about the furnace. That is about 1 min and 20 sec to ramp up. Now watch the count-down timer on the Infinity stat (you can't use the video minutes since that part of the video was accelerated and not in real time). You can see the compressor RPM start to command higher at 24:48 (so that matches with video minute 2:27 of the outdoor view) and if we go 1:20 later and pause it, it is at 4245 RPM. Then 30 seconds later, it is at 4806 RPM. So yes it did ramp up another 500 RPM after the camera cut away. Please note that both 4245 and 4806 RPM can be 5th stage. The stage is NOT a specific speed. The staging is actually specific BTU capacity. So as the refrigerant temperature and pressure continued to change, the system continued to adjust the RPM to get the desired BTUs (about 3 tons, in this case). It should also be noted that it was only 83 degrees out the day I filmed this with John. So it did not necessarily need to fully ramp up to 4800 RPM to get the full 3 tons (all 5 stages) of cooling. The colder the outdoor ambient, the lower the compressor and condenser fan speeds needed to achieve the desired capacity. Anything less than 95 degrees outside, will often result in lower RPMs needed under most operating conditions. I have these units in our Illinois training labs in Melrose Park, North Aurora, and Lansing, and I would welcome any local HVAC contractors to come in and play with these for themselves. We use the furnaces in the lab to simulate hot days and make these units truly ramp all the way up. I am not an acoustical engineer, but I cannot hear the difference between 4200 and 4800 RPM... but we have to make it hotter in the lab to prove that out to the technicians in our training classes.
Justin, you seem like a pretty perceptive guy. Do you work in the HVAC industry? If you do, and you are in the Midwest, we should connect. We like to work with smart contractors.
@@TECTubefilms The inverter compressor does not rapidly change speed. It takes at least 3-4 minutes to get to the 5th stage. It will slowly ramp up to 3rd stage and hold then go to 4th stage and stay there for about 30-60 seconds and then will ramp up to 5th stage. When the unit turns off and is in a higher stage, Example: 5th Stage, the compressor will slowly ramp itself down to shut off. There is no instantaneous shut off.
The unit depicted in this video has variable speed compression, however it is controlled to 5-stages. It is a Carrier 24VNA9. There is an upgrade to this model that is "fully variable speed" and even quieter (as low as 51db vs. 56). It would be a 24VNA6 model.
Annoying sound at stage 5, not a smooth sound. Wish you would have demoed the start up sound. My compressor, on a builder grade AC, has a loud bang on startup.
We did not think to record it when it turns on because there is no "start-up" sound. In fact, when we run the units in our lab for our students, they can't tell if the unit started or not and have to walk over to it to look at the fan blades. It is a slow ramp up. No loud bang at startup. This is not like your builder grade A/C at all.
@@TECTubefilms After listening again 2:20 onward has a high pitch whistling sound. Not just the rattle. Also, the beginning is squeaky. I'm admittedly sensitive to this. Inside sounds great though. Good to know that there isn't a startup sound.
@@Mr_Magoo_ That higher frequency noise is perceivable, but much lower than other noises. It is more noticeable when close to the unit. In our case, our video guy had a cattail boom mic just a couple feet away from it to pickup all sounds. All inverters and VFDs have this sound... similar to the sound you would have heard behind your old tube TV back in the day. This type of higher frequency sound does not travel through the home structure like the lower rumbling sound of a traditional unit would.
@@Mr_Magoo_ The ability to hear the sound is also age dependent. Older folks generally cannot hear it all... even when standing next to it. Younger folks can hear it 10 or even 15 feet away. You must be youthful :)
I am the owner of the system at this house and I am EXTREMELY happy. Obviously, I am a little biased, but it has been awesome and my wife loves it too. We have recommended the same system to over 10 friends and neighbors also.
I have this unit and I wouldn’t recommend it to anybody that lives in cold areas. Unit is great in summertime but in cold weather I live in ct it’s terrible. Today it is 10 degrees outside and the outdoor unit is not even turning on!!! Only air handler with aux heat. 1 year into it had a part go bad cost me $700 to fix because carrier didn’t want to cover their own warranty. This unit was the biggest mistake I ever made
The system in this video is a gas furnace for heat and a straight air conditioner for cooling. What you are describing is a heat pump system. Apples and oranges.
In regards to an Infinity heat pump (which is different than this video), there are multiple models. One of the models, which is a 25VNA8, only runs heat mode down to 10 degrees in heat mode and this is published in its specs. It can be used in mild climates. It can also be used in cold climates like yours and ours, however, in a cold climate it needs to be used in a dual fuel system where it runs as a heat pump down to a certain outdoor temp and then it switches to gas heat below that. It sounds like someone mis-applied a 25VNA8 with auxiliary electric heat in your climate. Instead they should have used a 25VNA6 or 25VNA0 which can run in outdoor temps well below zero.
In regards to the $700 and "Carrier not covering their own warranty," what happened? Did Carrier refuse to warranty the replacement part or did Carrier give the free part, but your HVAC contractor charged you $700 to install it? The HVAC industry, unlike the auto industry, has the manufacturer warranty parts only and the contractor handles the warranty labor. This is because cars are 100% built in a factory by the manufacturer, but HVAC systems are half built in the field by the contractor. This is not specific to Carrier. It is the same for all equipment manufacturers.
And it's kind of lame actually. Especially if the infinity thermostat breaks but to get a new one under warranty you have to pay the HVAC guy an inflated amount to bring it out and hook it up.
If you can hear it running from the front of the house or anything like that, then something is wrong with your specific unit. We have a bunch of these in our hands-on training labs. Sometimes we turn them on before students arrive. Then we during a furnace class or whatever, we ask them if they want to hear one of the inverter units run. When they say "yes," we tell them that it is already running. Guys are shocked and run over there to see if the condenser fan is on.
We are not familiar with Trane so we just visited their website. It says the quietest A/C is the XV18 and it is 57 to 75 dbA. The Carrier Infinity unit in this video is a 24VNA9 and its literature states the sound is 55 to 73 dbA. Both are pretty quiet and the Carrier is a little quieter... at least in the sound tests. Check out www.shareddocs.com/hvac/docs/1009/Public/00/24VNA9-09PD.pdf
@@Chris2745100 If you use an Infinity/Evolution/Ion wall control, then it will ramp up and down the 5 stages automatically based on a ramping PID loop using space temperature deviation from setpoint, which would be similar to cruse control on your car. If, however, you just put a 2-stage thermostat on it, then it will be dumbed down to 2 stages (just using stage 2 and stage 5) in a more traditional fashion.
Carrier already has published decibel ratings. For this model number condensing unit (24VNA936), it is 56 dBA on stage 1 and then 71 dBA on stage 2. We made this video so homeowners and residential dealers could better understand what that means. While decibels are meaningful to engineers, most people don't relate to that. FYI - this also publish Octave Band data too.
That house is 2,860ft2 and the unit is 3 tons. And that is more than enough capacity. If Carrier had a 2.5 ton version of that unit, we are pretty sure Ryan would have installed that instead.
@@TECTubefilms Correct. Instead of a 3 ton 5-stage, I essentially have a 2.5 ton 4-stage because I NEVER need that last stage. The oversizing issue caused by the HVAC industry is real. Half the houses in America have a double sized A/C! #GoSmall
It would be helpful if you could provide some details to support your random claim. We have had great success with Day & Night brand, which is part of ICP, since 2008. In fact, we liked it so much we also took on the Heil line a couple years ago which is also ICP. Is there some brand you prefer over ICP?

If you want whisper quiet you need one of these 19 seer 5 speed condensers. You will not get that in any single stage 14 seer unit. We do not deal with tempstar specifically, but we do deal with ICP. ICP does make one of these DC drive condensers. We even have a video on it somewhere.
@@TECTubefilms Thanks! :) I was wondering about the higher Seer units. Does it cool the house as good as 14 seer?
@@TECTubefilms Also, I meant the Air Handler and not the Condenser. I want the air handler that is whisper quiet. Does higher Seer mean much quieter?
@@dmana3172 If you check out Carrier's website, you will see comparisons of all different units. Use that tool to find the right unit for your home. If budget doesn't play a role, but you want comfort and quiet, always go with the "Best" option.
@@TECTubefilms Thank you for your input. I will take that in consideration by tomorrow. You really helped me. :)
How many tons this unites
It is available in 1, 2, 3, 4, and 5 ton sizes. The one in the video is 3 tons.
Also, it sounds like an aircraft engine spooling up when it ramps up.
What is that for an actual house I live in a city how
Huh?
question? Does altering the cfm through the stat or dip switches, lets say standard 350cfm/ton to 400cfm/ton, mess with the staging and dehumidification ability?
No, it does not alert the staging sequence. Yes, it does affect the dehumidification. To use the dehum features, leave the A/C airflow setting on "Comfort" and do not increase it to EFF325, EFF350, or MAX.
Keep an eye out for the setting switches video coming out in the next few weeks!
its quiet outside OK, what I want is a QUIET interior blower fan.. this old blower type is either set up wrong like they put an angle or turn right away cuz you hear the wind hitting something and its loud, no motor noise, belt noise no vibrations, squealing none of that, its that barrel blower grabbing the air its LOUD, I want a quiet blade style.. that variable speed is energy saver, specially if you have zones and you warm those up where you don't use em, then warm up zones like bedrooms to warm until you go to bed, its all done in the thermostat so an hour before bed you automatically have it cool it down to your comfy temp.. I don't cool where I do not use, not as much anyway, I keep my place at 78 in the summer, 80 in the living room, then my bedroom 77 when I sleep, in the south its like that, you acclimate and anything under 78 is cold, you don't do 72, no way, you step outside to 114 and it's too much..
down shot is that anything under say 77-78 and you get cold, no jokes, so if it drops to 74 my heater comes on, 76 is too cold for me, even with jammies on, Mena I do at times when its right there I hack it instead of turning the heat on, sweaters so forth, but if its 64 outside, and its 72 inside? heats coming on, just for a bit then its good for along time, but if its 40 outside and its been 40 fora few days, yea heat comes on regular like and I go for comfort zone, 78-80..
I hate when stores have to down to like 74 or so, freezin man! most are good they try to please everyone so they split it down the middle... snowboarders live at 72-73, locals live at 78-80, so they shoot for like 75-76, which is doable... odd but you can feel a few degrees down south, yup... until it's over like 100, then it's like is it 100 or 105, but at 107 you know it, then when its over 112? yup you know that too... odd its right around 112-114 where you get burnt on door handles, 98 if its a chrome door handle... "remove your fingerprints today" also if you let like 100+ shine through your windshield and onto your steering wheel, it will burn you when you grab it, you learn, window cover on the OUTSIDE of your window, they have special types, then a cover over steering wheel, hale i have all teh shade spots sorted where I am and I will walk a quarter mile to get on, you kidding me? I see people in 118 degree heat park windshield into the sun, no shade blocker, then get in, fire it up, turn AC on and go.. FUGG THAT! you see melted dashboards now and then, specially at wrecking yard and the dump..
time of day and shade spots is the only way to survive in the southwest...
We are not sure what you are trying to say or trying to ask us. It seems like you were using voice recognition and started rambling on conversation style. If there is something we can help answer for you, let us know... in 50 words or less LOL.
BTW - the indoor blower in this video is super quiet. And this house does have a zone damper system and Ryan does normally set the cooling for 77 degrees in the summer.
The a/c was only in stage 3 when you said it was in stage 5. When you ended the video it ramped itself up to stage 4 and not all the way up to stage 5.
How do you mean? We used the "check-out" mode to directly command the staging and we only used stage 1 and stage 5.
To add some clarity, I think I know what Justin means. I re-watched this about a year ago when someone else asked and luckily I saved my notes...
For the outdoor view, look at minute 2:27 of the video and that is when the compressor starts ramping up. Then look at 3:48 when we cut away on the edit to start talking about the furnace. That is about 1 min and 20 sec to ramp up.
Now watch the count-down timer on the Infinity stat (you can't use the video minutes since that part of the video was accelerated and not in real time). You can see the compressor RPM start to command higher at 24:48 (so that matches with video minute 2:27 of the outdoor view) and if we go 1:20 later and pause it, it is at 4245 RPM. Then 30 seconds later, it is at 4806 RPM. So yes it did ramp up another 500 RPM after the camera cut away.
Please note that both 4245 and 4806 RPM can be 5th stage. The stage is NOT a specific speed. The staging is actually specific BTU capacity. So as the refrigerant temperature and pressure continued to change, the system continued to adjust the RPM to get the desired BTUs (about 3 tons, in this case).
It should also be noted that it was only 83 degrees out the day I filmed this with John. So it did not necessarily need to fully ramp up to 4800 RPM to get the full 3 tons (all 5 stages) of cooling. The colder the outdoor ambient, the lower the compressor and condenser fan speeds needed to achieve the desired capacity. Anything less than 95 degrees outside, will often result in lower RPMs needed under most operating conditions.
I have these units in our Illinois training labs in Melrose Park, North Aurora, and Lansing, and I would welcome any local HVAC contractors to come in and play with these for themselves. We use the furnaces in the lab to simulate hot days and make these units truly ramp all the way up. I am not an acoustical engineer, but I cannot hear the difference between 4200 and 4800 RPM... but we have to make it hotter in the lab to prove that out to the technicians in our training classes.
Justin, you seem like a pretty perceptive guy. Do you work in the HVAC industry? If you do, and you are in the Midwest, we should connect. We like to work with smart contractors.
@@ryanhoger1 Thanks for chiming in. We were about to type the same thing. :)
@@TECTubefilms The inverter compressor does not rapidly change speed. It takes at least 3-4 minutes to get to the 5th stage. It will slowly ramp up to 3rd stage and hold then go to 4th stage and stay there for about 30-60 seconds and then will ramp up to 5th stage. When the unit turns off and is in a higher stage, Example: 5th Stage, the compressor will slowly ramp itself down to shut off. There is no instantaneous shut off.
5 stages? Variable speed?
The unit depicted in this video has variable speed compression, however it is controlled to 5-stages. It is a Carrier 24VNA9.
There is an upgrade to this model that is "fully variable speed" and even quieter (as low as 51db vs. 56). It would be a 24VNA6 model.
highest decibel?
This unit in the video is a 3 ton, so it ranges 56 to 71 dBA. The range for all sizes is 55 to 73.
Annoying sound at stage 5, not a smooth sound. Wish you would have demoed the start up sound. My compressor, on a builder grade AC, has a loud bang on startup.
We did not think to record it when it turns on because there is no "start-up" sound. In fact, when we run the units in our lab for our students, they can't tell if the unit started or not and have to walk over to it to look at the fan blades. It is a slow ramp up. No loud bang at startup. This is not like your builder grade A/C at all.
What annoying sound at stage 5? Are you talking about that slight rattling noise around the 2:40 minute mark of our video?
@@TECTubefilms After listening again 2:20 onward has a high pitch whistling sound. Not just the rattle. Also, the beginning is squeaky. I'm admittedly sensitive to this. Inside sounds great though. Good to know that there isn't a startup sound.
@@Mr_Magoo_ That higher frequency noise is perceivable, but much lower than other noises. It is more noticeable when close to the unit. In our case, our video guy had a cattail boom mic just a couple feet away from it to pickup all sounds. All inverters and VFDs have this sound... similar to the sound you would have heard behind your old tube TV back in the day. This type of higher frequency sound does not travel through the home structure like the lower rumbling sound of a traditional unit would.
@@Mr_Magoo_ The ability to hear the sound is also age dependent. Older folks generally cannot hear it all... even when standing next to it. Younger folks can hear it 10 or even 15 feet away. You must be youthful :)
That whip looks terrible and the disconnect is way to low..
It looks better than Ryan's lawn LOL
Too many bells and whistles on the carrier infinity
Which bells and whistles are too many?
I am the owner of the system at this house and I am EXTREMELY happy. Obviously, I am a little biased, but it has been awesome and my wife loves it too. We have recommended the same system to over 10 friends and neighbors also.
I have this unit and I wouldn’t recommend it to anybody that lives in cold areas. Unit is great in summertime but in cold weather I live in ct it’s terrible. Today it is 10 degrees outside and the outdoor unit is not even turning on!!! Only air handler with aux heat. 1 year into it had a part go bad cost me $700 to fix because carrier didn’t want to cover their own warranty. This unit was the biggest mistake I ever made
The system in this video is a gas furnace for heat and a straight air conditioner for cooling. What you are describing is a heat pump system. Apples and oranges.
In regards to an Infinity heat pump (which is different than this video), there are multiple models. One of the models, which is a 25VNA8, only runs heat mode down to 10 degrees in heat mode and this is published in its specs. It can be used in mild climates. It can also be used in cold climates like yours and ours, however, in a cold climate it needs to be used in a dual fuel system where it runs as a heat pump down to a certain outdoor temp and then it switches to gas heat below that. It sounds like someone mis-applied a 25VNA8 with auxiliary electric heat in your climate. Instead they should have used a 25VNA6 or 25VNA0 which can run in outdoor temps well below zero.
In regards to the $700 and "Carrier not covering their own warranty," what happened? Did Carrier refuse to warranty the replacement part or did Carrier give the free part, but your HVAC contractor charged you $700 to install it?
The HVAC industry, unlike the auto industry, has the manufacturer warranty parts only and the contractor handles the warranty labor. This is because cars are 100% built in a factory by the manufacturer, but HVAC systems are half built in the field by the contractor. This is not specific to Carrier. It is the same for all equipment manufacturers.
And it's kind of lame actually. Especially if the infinity thermostat breaks but to get a new one under warranty you have to pay the HVAC guy an inflated amount to bring it out and hook it up.
I can hear that compressor from a mile away, compared to Trane this is loud as hell.
If you can hear it running from the front of the house or anything like that, then something is wrong with your specific unit. We have a bunch of these in our hands-on training labs. Sometimes we turn them on before students arrive. Then we during a furnace class or whatever, we ask them if they want to hear one of the inverter units run. When they say "yes," we tell them that it is already running. Guys are shocked and run over there to see if the condenser fan is on.
We are not familiar with Trane so we just visited their website. It says the quietest A/C is the XV18 and it is 57 to 75 dbA. The Carrier Infinity unit in this video is a 24VNA9 and its literature states the sound is 55 to 73 dbA. Both are pretty quiet and the Carrier is a little quieter... at least in the sound tests. Check out www.shareddocs.com/hvac/docs/1009/Public/00/24VNA9-09PD.pdf
BTW - the unit in the video (24VNA9) is not even the quietest model Carrier has. The 24VNA6 is 51to 68 dbA.
@@TECTubefilms I am assuming the system also does this automatically; moving up or down the stages depending on the cooling demand.
@@Chris2745100 If you use an Infinity/Evolution/Ion wall control, then it will ramp up and down the 5 stages automatically based on a ramping PID loop using space temperature deviation from setpoint, which would be similar to cruse control on your car. If, however, you just put a 2-stage thermostat on it, then it will be dumbed down to 2 stages (just using stage 2 and stage 5) in a more traditional fashion.
Kind off meaningless without a decibel reading.
Carrier already has published decibel ratings. For this model number condensing unit (24VNA936), it is 56 dBA on stage 1 and then 71 dBA on stage 2. We made this video so homeowners and residential dealers could better understand what that means. While decibels are meaningful to engineers, most people don't relate to that. FYI - this also publish Octave Band data too.
Helps that the model you are listening to is sized for a doll house. Need about 7 of those to cool that house.
That house is 2,860ft2 and the unit is 3 tons. And that is more than enough capacity. If Carrier had a 2.5 ton version of that unit, we are pretty sure Ryan would have installed that instead.
Haha. I have lived in that house for 18 years. 3 tons is plenty to cool it.
@@TECTubefilms Correct. Instead of a 3 ton 5-stage, I essentially have a 2.5 ton 4-stage because I NEVER need that last stage. The oversizing issue caused by the HVAC industry is real. Half the houses in America have a double sized A/C! #GoSmall
It looks like your lawn is too tall.
Any quality contractor or trainer would make sure their lawn were mowed before shooting a video... Geez.
Ryan is a lazy slob. At least he combed his hair for the video. :)
I let it grow long to annoy my neighbor... and random viewers of our videos.
Someone can even be triggered by long grass I guess.
ICP JUNK
It would be helpful if you could provide some details to support your random claim. We have had great success with Day & Night brand, which is part of ICP, since 2008. In fact, we liked it so much we also took on the Heil line a couple years ago which is also ICP. Is there some brand you prefer over ICP?
BTW - the system utilized in this particular video was a Carrier Infinity system, not an ICP system.
Lol l am learning the sequence of operations now in school. Took off my first blower motor.
