I see a lot of disdain towards Lennox in the HVAC and plumbing subs sometimes, but damn, I just got my first house about a year ago and I love this AC unit. It’s the quietest one I’ve ever had. Sitting outside in view of it you can barely notice it, and it cools the house well.

Any tips to help keep this thing alive other than hose down the coil periodically?

Do I have this air filter set up correctly facing up?

Water pours out of at least 5 to 6 different points in this HVAC system about once a day around three in the afternoon. They have checked the drain pipe and say that it is not clogged. The filter has been cleaned. It’s not super humid where we are. it is a bakery kitchen.

Only this one out of 5 makes this noise

It’s probably 70F outside, we like to sleep cool so we turn this on to 65

It continues to make this noise for 10 min after we turn it off

Any suggestions. I won’t have a handyman available till Friday. Thank you so much for your advice. First time homeowner and I’m non handy husband unfortunately. So any advice helps 😅

Hi Reddit!

I live in socal where summer is just kicking off. My wall unit was just replaced end of April, so this is only my third time using it. The first time I used it last week, it was crispy cool & the room felt good. It didn’t extend all the way to my kitchen (open concept kitchen/living room situation) but the living room side cooled down noticeably. Yesterday & today, though, I’m feeling almost nothing. The air is cool when I stand right up against it, but once I’m 2-3 feet away I can only feel the cool when my tower fan pushes it onto me. If the tower fan is off, I feel almost nothing.

I understand it’s just hot out & if that’s just it then fine. I will say, though, that my old wall unit did not have this problem. The entire kitchen/living room could be noticeably cooled. So I figured I’d ask if I should just reset my expectations w this new unit before I submit a maintenance request.

Thanks for any advice!

Location: New Orleans. My minisplit is 1.5 years old and was overcharged during installation due to an installer error. The install was finalized on Christmas eve, and It was working, so i did not want to push the issue. I read that overcharged units would show symptoms more in extreme heat than cold. Well the heat has come and it's been working its ass off to keep the house at a decent temp.

I think it may be time to bite the bullet and have the system calibrated. What would be a fair price to pay for a tech to pump out everything, weight it, and put back in the correct amount?

Two brand new Carrier infinity units and still this chattering during AC startup. Last 2-15 seconds and seems to be loudest at the air handler.

Hi all,

I wanted some input on whether or not the prices I am being charged are fair. This is for a rental property and I don’t live in the area. I was recommended an HVAC tech who could do some work for me on the side. I feel like his prices are lower than if I just called a random company but they seem a little high to me. I just want to be sure I am not being taken advantage of. This is in North/Central Florida.

The unit is original with the home so it’s about 20/25 years old but in relatively good condition. New tenants moved in and said the unit was not cooling the house properly. They set it to 72 but it wouldn’t get below 76. So I called this guy.

He said the blower motor was bad and needed replacing, the capacitor was low, the coolant was low, and the condenser coils could use cleaning. He was upfront and said the only thing I NEEDED was the blower motor and the rest could wait but since it’s old and if I wanted to do everything I could to try and get the most life out of it, he would recommend doing the other things as well.

He replaced the blower motor, the capacitor, added 2 pounds of R22, and cleaned the condenser coils and charged $750. He originally wanted $880 but we negotiated down to $750.

He also said that if the unit dies within a year he would subtract this price I paid from the cost of installing a new unit.

We spoke about adding a soft starter and he said that would be $175 if I wanted just to protect the unit and increase the lifespan (I ultimately declined).

Some of his other prices: on another unit that was about 5 years old where the compressor overheated he charged me $520 to add a soft start and capacitor.

He has also quoted me a whole system install for a 1500 square foot home a 3 ton heat system for $7,750 (the brand was a carrier owned brand but not carrier. He said it was the same just not labeled carrier).

So, how are these prices? Are they good deals or is he taking advantage of me?

My dad does a lot of repairs himself and he said the blower motor is either good or it’s not and it can’t be “failing” like this tech told me so I am not sure who to believe.

I have a water leak coming from my down flow York air handler. Small amounts of water leave the air handler where the gas freon enters the handler. Should I open up the right side of the air handler to see why this is happening?

I’m 18 months into my first home. The sellers added a 24 month home warranty instead of replacing the 24 year old HVAC. Fine, we love the house. Of course, we’ve had trouble with the thing on a regular basis. Every time there’s an issue, the warranty company charges us 80$ and sends out the their preferred contractor to put a band-aid on it. It got to the point where I’d hire someone to diagnose it and only then can the warranty company so that I could verify their story.

Well, a month ago my air conditioning went out during a heat wave. I call an independent to diagnose, turns out my old-ass air conditioner has a leak. The outside cables are frozen, definitely a leak. The independent tells me the thing needs replaced, even if they wanted to repair it, the unit takes R22 which they don’t make anymore. So, armed with this info I call the warranty company, and they send their guys out, who proceed to put a bunch of R422B in my system. Thankfully I have it all on camera. I didn’t complain at the time because I know nothing about HVAC and figured my system must’ve been retrofitted at some point. For context, they didn’t even find the leak as there must be “two refrigerant incidents before the warranty company will allow us to find the leak”.

Fast forward to this week, my house hasn’t been hitting the thermostat temp consistently. I’m keeping it above comfortable room temp, the AC is always well above (unless it’s a cool day). I call the warranty guys and tell them there’s still an issue, they charge me anyway. I tell them I want a different contractor. They send a new contractor, much more professional, he tells me my coil needs cleaned and that my system is not retrofitted. I tell him what happened with the previous contractor and he lets me know it’s a problem that should be fixed.

I send the warranty company my evidence and they go radio silent but go ahead and authorize repairs by the new guy AND try and send the shitty R422B guys back to “fix their mistake”. Keep in mind they don’t tell me what they’re going to do— I assume because they don’t know or want to know. As I see it, the only thing that can be done is draining my system, finding the leak, fixing it, and either retrofitting or using R22 to charge my system back up. The warranty agents don’t seem to have the time or inclination to understand, and they insist I must let the shady contractors back to remedy the issue, which I will not allow.

Does anyone have a similar story? Can anyone advise me as to how I can get a good outcome here?

Has anyone worked for Lennox? Im fixing to start as a hvac install commercial apprentice and I want to know if they teach well. Advice is much appreciated about tips installing rtus!

I have a Carrier Infinity heat pump system.

I received a code 84 High Pressure lockout signal. I noticed the condenser cooling fan was not running. Technician looked at it and said probably the fan motor was bad. He suggested getting a whole new unit. (This one is 10 years old). He also said he could replace the fan motor and order a new defrost board as a backup.

I put a heavy duty fan blowing on the side of the outdoor condenser assembly. A few minutes later the heat pump was running and the condenser cooling fan was also running! Any thoughts?

I have been given a quote of $500 to clean the air handler in the crawlspace under my 1350 sq. ft. house in South Carolina. New unit was installed in 2020. Is this price reasonable? And how often should it be cleaned? Thanks!

From what everyone is saying, I should change the air filter monthly and have a go at cleaning my outer unit first (myself, thanks to YouTube) before shelling out $500 for cleaning the air handler. Have I got that right?

This is what the unit looks like now, although I did hose it down, which cleared out a lot of debris, after I took this picture.

I have a Rheem water heater that's only 3 years old. A few months ago it started to send me this message:
"An issue has been detected with your Heat Pump Water Heater Gen 5 named Heat Pump Water Heater located in Home: T005 Heating source defaults to elements due to low airflow. If issue persists, please contact Rheem Tech Support 1-800-995-0982 or your local plumbing professional. Reference Alarm Code T005."

There's not much stuff next to it so it should have enough space. The filter looks clean, and I cleaned it anyway just to make sure. Still I receive such message every day. Any advice what I can do about this, please?

I’m trying to replace a dead motor in my heat recovery ventilation unit. I did take out one fan, but I’m having a tough time taking the other fan out. I can’t access that 3mm as it’s seated deep inside. Is there a way of taking this out that I’m missing? Also, are there any places that sell the whole assembly so I can replace the whole motor and the fans? Any help is appreciated. Thanks.

For those of you who track it, roughly how many second visits / callbacks are you running per month on service work these days? And do you have any sense of what each one actually costs once you add labor and the lost job?”

I’m getting the HVAC done on my current live-in house and here’s the quote with the specs. 1,5000 sq ft house will eventually be a rental but all HVAC and water heater are 25+ yrs old so needs done.

AC
Furnace
50 Gal water heater
Insulation
New returns installed
2 new bathroom fans installed with them bringing it up to code by venting them out of the house

Reputable company with a 10 yr parts and labor warranty

~$16k+ before rebates they’ll also do 0% financing for 5 years. The deal feels legit what do yall think?

A family member is upsizing their AC and has offered this unit to me.

My current AC unit is a Amana. Probably 20+ years old. Likely installed the same time as my furnace in 2001. All the labels and stickers are weathered and unreadable.

My house is a cape cod (1.5storey) 1100sqft.

Any problems with this air con? Should I have it installed.
