I've learned that if you read the 1-star reviews and problems for each type of unit, you would never buy anything. I've yet to find a true 5-star product. If a manufacturer is growing sales and market share, there must be a reason. I hope I don't have to eat my words!

Is this the same as Allied units?

waw im in love this channel the info is fenomenal

Tell me you’ve never worked on hvac without telling me you’ve never worked on hvac

But here in Europe R290 and R600 are being used in refrigeration, fridges and freezers, in many supermarkets as well. The industry does not care about technicians' safety.

This add has been Brought to you by EPA lobbyists.

More important at what temperature (cold) does each start to lose efficiency.........

Next time add PRICES

Some people are going to go from r22 straight to r32.

This has to be the most ridiculous thing I’ve heard. I get it their opinion but the entire world of HVAC knows Lennox is JUNK so much so there’s a class action lawsuit on them for that JUNK. Just google it. Maybe they’ve been paid 🤷🏾‍♂️Ijs

I just had my whole system done ductwork and vents cut in. They installed a Trane system. They did an awesome job on the installation and the price was super good.

i filled up my VRV with R454b which was factory charged with 410A... All good no issues here. Machine running even more smooth. You should try this one time on the channel.

why does it feel that they are putting more computers into something that is made just to cool or heat a space? eventually it will need windows updates #sarcasm

It rather obvious you guys have a bias

No difference at all....

NO LENNOX! I LIVE IN SOUTH BAY AREA OF SO CAL. THE COMPRESSOR WENT OUT 5 MONTHS AFTER THE 5 YEAR WARRANTY WAS UP!

Thanks for the tips my fellow HVAC technicians ❤❤❤

YOU COULDN’T GIVE ANOTHER LENNOX SYSTEM! I PAYED $14,000 FOR A WHOLE NEW HVAC SYTEM! I HAD IT SERVICED/PREVENTIVE MAINTENANCE PERFORMED TWICE EVERY YEAR! THE COMPRESSOR MYSTERIOUSLY WENT OUT 5 MONTHS AFTER THE 5-YEAR WARRANTY EXPIRED! I LIVE IN THE SOUTH BAY AREA OF LOS ANGELES NOT TOO FAR FROM THE OCEAN…WE USE THE A/C MAYBE 3 TO 4 MONTHS OUT OF A YEAR! THEY SAID THEY COULD NOT FIX…I BROKE DOWN AND CRIED LIKE A BABY; NOT BECAUSE I WAS A PUNK…BUT BECAUSE I WAS SOOOOO MAD! THE NEW SYTEM COST ME OVER $10,000…THAT’S $24,000 ON HVAC SYSTEMS IN 5 YEARS AND 5 MONTHS!

I just put a brand new Amana A/C and I was wondering is it normal for the ac runs 10 to 15 minutes and cuts off for 5 minutes and runs again. I set it to 77.

it's all about money, nothing to do with environmentally friendly "my beep", sick of this manipulator wake up people

How about when we braze the condenser and that copper pipe get heated is it dangerous, what do you guys recommend

It's 3

Hey Chris! Glad to see you on here!!!!

I live in Florida. I built my home in 2005 with 2 Lennox systems. They have been very reliable although we had to have it maintained. Well 19 years later, we are calling HVAC repairman and all are saying they no longer can get the "Freon". Some say its not worth paying $500 for Freon, as it is an older system and that we should replace it. We have had 3 estimates but they are all run somewhere about $17,000 for the two units. I have a two story house. I can not afford, the higher end Lennox, Traine, Carrier but one company is bidding $14,000 if we pay cash and they only offer Goodman. Do you recommend Goodman. Thank you.

Marketing strategy,, not good for costumer

Good video. I'm going to go ahead and buy some cling wrap for the gasket but not sure if I'm ready to do the bag trick as that's pretty much irreversible unless I cut a hole in my wall

My R22 is still running from 1967. Its amazing and crazy cold.

It’s cool seeing these units out. We assemble those Goodman Air handlers, looking by the date on the Drainpan I was currently running the Air handler assembly line, my team most likely built that exact unit. Great video!

Everything we must Try one time. So I just bought Rheem Condenser 2.5 ton 14.3 SEER2 this month. Will install myself

I live in SC. My system runs every day of the year. My 18-year-old goodman heat pump is still running strong. My daughter had a 9-year-old Carrier condenser go bad. It had leaked all over. I replaced it with an Oxbox by Lennox.

Good video, but also important if you can design or have location where you can get all the way around air handler to seal to plenum, otherwise might be impossible to completely seal all sides.

My Parents had a 1976 Carrier round one Heat pump installed and never had one problem with it save for it needed cleaning on the outside. We replaced in 2008 with a American standard 20 seer 5 ton heat pump with twin reciprocating compressors in it. A 5 ton compressor and a 2.5 ton I think. The carrier was more reliable but the American standard has been very good. The inside coils had to be replaced in 2014 but they paid for it all and after that no problems. It runs always just about very rarely using the 5 ton compressor. I don't trust Trane/American standard anymore. They used to make there own compressors and there reciprocating compressors were bullet proof that why there prices were higher. Well I had to replace a Trane 14 seer compressor not long ago on my rental unit I own. It was a L.G. that was pulled out of it. I was mad as hell cause I was told that's why are prices are higher cause we make our own. Which was a lie . I confronted him about it and produced my recording of him telling me that, which I always do with contractors. My three year old Gibson heat pump fried itself and not worth repairing. I installed a Ruud 15 seer heat pump in my house(8900$). Well it sucks bad. They don't have a accumulator for a heat pump and no compressor belly band heater . Its very weak on heat and LOUD as hell.. I bought me a dirt cheap 18,000 btu Mini split heat pump for 700 bucks and installed it myself. My house has a open floor plan this mini split cools and heats my whole place just fine. It got 2 below zero here last winter this mini split keep the house at 69 F no problem.My power bill dropped 40 bucks a month this system is a 23 seer and is silent. NO more large systems that are loud and break and even if this mini only last three year at 800 bucks to replace the whole thing is a no brainier. I did it myself and took me about 7 hours . The heating and air guy wanted 5000 bucks to do it. Which I laughed at him , I understand making a profit but that was a ripoff .

I like this video.

I noticed you took down the previous version of this video after i commented on the error in the CFM calculation. Or was it just my imagination? 🧐🤔

Only if the person who did my HVAC didn't seal all my ducts with a half of tub of sealant on every connection.

can you do a vid on pros and cons of CFM vs velocity? what matters in most houses? they often talk about this also in leaf blowers

Excellent advice. Thanks so much.

The whole flammability concern is absurd. Many houses have a natural gas meter near the compressor, but I guess the EPA never noticed those. I installed a 1.5 ton Della mini-split SEER 22 last Spring which came charged with R32. Made by Medea, like most Chinese brands. I bought to better use my solar energy, just heating and cooling the living areas, but the little guy cooled my whole 2200 ft2 house this summer, even on 110 F days. Good since my central AC died right after I got it running.

The HVAC industry wasn’t ready for A2Ls when it launched outside the US, and it still isn’t ready today, the only circumstance when the refrigerants flammability is an issue is when techs aren’t using key best practices when brazing including; recovering into a vacuum, purging with nitrogen after recovering, CUTTING OUT ALL COMPONENTS NOT SWEATING OUT and flowing nitrogen when actively brazing. The problem is 99% of Techs aren’t doing these practices, which is going to result in igniting the refrigerant when brazing under some circumstances. Otherwise A2L refrigerants like R32 and R454B are fine.

I don't like an upside down board you went the wrong way

Jaquar heat pump E02 lack of refrigerant ERROR HOW TO FIX PROBLEM

I'm skeptical, and I'd need to see some real world examples of hot or cold walls skewing temperature readings enough to cost "a fortune"

I really dislike the practice of cutting the vent hole in the drywall and leaving the exposed drywall. Air quality is a much greater priority than ever, we should really be sealing up that drywall so that the dust isn't getting picked up by the vents. And for those that want to try and dismiss that concern, you're indeed incorrect. It is a big deal. Yes, there is a lot of dust within a home, including new construction or remodels, but things should also be cleaned far better to remove as much as possible. In addition, sealing air infiltration points from unconditioned spacing is important and that includes these vents, anyhow. Also, I think extra work should be done when extending a duct to ensure that overlapping insulation doesn't separate. Some tape internally and even a zip tie externally. Some movement or shifting when setting the duct or blowing insulation likely will mess it up, even if you've gone through a lot of effort to create "slack" internally. It also looked like you were going to handle it, but when you taped the duct to the collar, the perforation in the lip is exposed. I would have covered that with the tape. The outer tape isn't enough. For air quality, we're talking about microscopic particulates and fiberglass is not something you want in your lungs. And... some better beer. :) Overall a great video, I think you did a great job, it was just things that I get very nit-picky about. You've performed a great service to the community!

to add, the only difference is to include but not limited to: 1. Its in an attic 2. you're crawling around on rafters 3. it's 100 degrees 4. its dusty, dirty and poor air flow, dead mice, rats and if you're lucky a raccoon 5. it's not at hip height, in a conditioned space and you can reach everything 6. you're swimming in insulation 7. you're wearing long sleeve shirts, mask, dickies trousers 8. You're working on sheetrock 9. Everything you touch is wet, because its 100 degrees and you're sweating on everything 10. Your drill battery dies 11. Your head mounted lamp keep slipping and then the battery dies 12. You're doing this for 3 days straight praying for a cloudy day or rain 13. You're going in and out through a scuttle in a closet 14. The customer wonders why this is taking so long and doesn't like you're playing 5FDP 15. The office gives you "Emergency" calls after you're done for the day because you're on-call 16. The office gives you calls because the customer specifically requests you. 17. The office gives you calls because the on-call guy called in for the day. Yea, okay.

My old central ac just stop working. R-22 condenser with a date code of 1989. Compressor finally went. Be hard pressed to get that longevity out of a new unit

Cool idea on the transition box...how do you know how big to make it? My system is 4 ton, 1600cfm but ducted for 1200 cfm, so I need to fix that. I was thinking of feeding 1 - 14" and 2 - 12" flex to 3 different zones of the house and build 3 transition boxes to feed all the room ducts. So...basically 700 and 480 CFM boxes, respectively. I was thinking 1 - 16"x16"x16" cube and 2 - 14"x14"x14" cubes. Would that introduce too much loss in the system?

What is the deal with the copper vs aluminum condenser? Why is aluminum better?

Hey great video i learned a lot.. i was taught that insulation and a good contractor that is knowledgeable makes a systems last a long long time…..

Recommended Daikin AC that uses R32 or R410? please help me answer because I want to install AC.

Awesome job gents...enjoy the content, keep it coming!
