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

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!

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?

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.

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 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?

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 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.

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.

I am looking for a thru wall ac unit that fits what seems like a non standard size sleeve. The sleeve is 24” wide x 14 3/8 tall. The old unit was already removed so I don’t know what was there before. It seems like they are all designed to fit a 26” wide sleeve.

I’m considering installing a new central AC system for my home in Saratoga County and recently received a quote from a firm I was considering for around $8,500. Before moving forward, I’d like to know if that sounds reasonable for the area.

For anyone who has replaced or installed central air recently, how much did your project cost? I’m very curious how much factors like size, efficiency rating, brand, ductwork, permits, and installation complexity affected the final price.

Are there any questions I should ask the HVAC contractor before signing the agreement? I’d appreciate any advice or experiences you can share. 

Is this overkill? We've just gone through the worst of the heat we get around here, max temps around 90° and feel like 110°F we've been renovating our newly purchased house and of course the ac that passed inspections died 2 days after closing. We've been using an older window AC my dad had lying around and to be honest it's been doing a fair job of keeping the main part of the house comfortable as long as we keep it running. The house is heavily shaded, but it is an older 1960s house. The windows are double hung.

I feel like 2.5 tons is overkill considering that's what my MiL just had put in her 2,200 sqft house that was built in 1970. On top of that she just paid $9k for the new AC and furnace to purchase and install but I'm being quoted $7k just for the ac and install. We both have crawl spaces the only difference is hers is accessed through the house and ours is accessed outside.

I have a Tempstar 3 and 1/2 ton AC unit that was installed in 2018 since then I've had to replace the blower motor inside three times, I just had to have it replaced the other day and I noticed a 255 warranty fee even though the motor was still under warranty, my AC company that installed it told me that warranty fee was enacted during the covid days when you couldn't do a person to person swap out for parts and that they never got rid of it is this true or is he just charging me for his profit?

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.

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?

I’m a DIY guy. And I’m looking for a good HVAC gaugenset that won’t break the bank. I’m drawn to the Fieldpiece SMAN but I don’t do this for a living. I like digital gauges but I could get by with analogue.

I’m an engineer and used to reverse engineer code to cheat on games, built mods for the PlayStation, and cloned cell phones. I’m pretty confident that I can learn enough to do what I need with the AC.

It’s hot as fuck in Texas right now and my upstairs AC isn’t keeping up. The temperature differential between the return and vent is only 5 degrees. I’m waiting for it to cool off a little before going into the attic and check things out but the condenser isn’t feeezing up. It had a filter from weeks ago and the unit is only a couple of years old.
