what is this weird filter at the back of my furnace air return

what is this weird filter at the back of my furnace air return

Posted On: April 8, 2023
Does anyone know what this filter is supposed to do in my air return? It is old and has shiny fiberglass looking fibers and based on how old the furnace was when we replaced it, I'd guess it was from the 90s. It's nasty and probably not doing much but not sure what the purpose is. Is it safe to remove? The first photo is where it is located and has a blue circle to show where it is and the red line shows how the filter is located within that duct. The two other photos just show what it looks like. Thanks!. Question from user passingby at hvacad...[More]

heating question from an enduser

heating question from an enduser

Posted On: April 7, 2023
Question from an End-User. Good evening everyone! I'm hoping some Good Samaritan will take the time to help out with this if they have any thoughts. A little backstory. I pay significantly below market value in rent for my new-construction two-bedroom apartment. The property manager is absolutely terrible but the cost more than makes up for it. However, I generally try and handle any small maintenance issues by myself (either DIY or bring in a handyman) to avoid having to get the PM involved. This may sound crazy to some of you but I'm very hap...[More]

thermostatic expansion valve keeps freezing

thermostatic expansion valve keeps freezing

Posted On: April 3, 2023
Four years ago I had a new unit installed and didn't have issues until recently. The TXV keeps freezing. The one in this picture is brand new, installed last after the first one kept freezing. My buddy that did the install no longer does HVAC. He suggested there may be a refrigerant leak. Any ideas what is causing this? The evaporator and condensor coils are clean and I just replaced the filter a few days ago. Question from user shaggysflt at hvacadvice at reddit.com. Answer: Assuming clean filter, airflow is good meaning not a lot of registers...[More]

I'm a homeowner that has gone through 2 HVAC technicians in troubleshooting a condensate smell issue in my house with no luck.

About a month or so ago, I started to noticing a strong acidic smell in 2nd floor laundry room's drain pipe, the same type of odor that is being emitted from my furnace exhaust pipe.

vacuum just the ac compressor

vacuum just the ac compressor

Posted On: April 1, 2023
So I was tasked with doing a compressor swap the other day and I hate the burning off of the Refrigerant when I sweat it out. So I got to thinking.. if the compressor is bad, is it possible to use the true suction and liquid line ports to isolate the compressor and vacuum it down to avoid breathing in fumes? It was a Trane unit with the the other ports so I don't see why you couldn't. Thoughts? Question from user GreyCap89 at hvacadvice at reddit.com. Answer: Just don't sweat it out. Cut the copper 6 in away from compressor. And get couplings f...[More]

I just had a new Carrier 59TP6B060V171214 furnace installed with a 16x25x5 inch filter housing. What's the max Merv rating that the furnace could handle? I would like to use a Merv 15 filter if possible. Question from user zahna4 at hvacadvice at reddit.com. Answer: My recommendation would be to upsize your filter cabinet when going for a more restrictive filter. As more filter area will give better airflow.

got a new hvac unit at our house we rent today and there is a problem

Posted On: March 30, 2023
We usually run the house low temp at night, and the old system took about 10 minutes to cool to that temp, and didn’t run much during the night. Any ideas? I think the old blower was a single stage and the new is an ECM ( I checked). Could this be why? Does â€�more efficient” mean crappier cooling? Question from user CardMonarch at hvacadvice at reddit.com. Answer: If you have the means to monitor the energy used, you will see a difference. You are already experiencing that difference. Your old system blew hard and fast. The new one...[More]

Posted On: March 29, 2023
Hi! I had a tune up done on my AC system a few days ago and after the guy left my ac system was blowing warm air inside and cold air from the outside condenser. My boyfriend checked it out and there was a yellow wire that had came loose and he put it into one of the spots fixing the problem and it came back out a few days later. I'm having someone new come out because I'm using a home warranty company and they're refusing to send out the same company without me paying so I'm having a new company come back. I had no issues prior to the tune up. ...[More]
