    Hello, I have a Goodman GSZ160301 16 SEER HP, 2.5 TON heat pump w/ the AVPTC37C14 Air Handler. The fan speed is 1/2 or less than my old unit - based on same exact ductwork + filter. The Comfort Cloud app is showing 460 CFM during heat pump heating. I wanted to up the speed because the suction...

    Hello, I purchased an air scrubber as the one shown here https://library.coburns.com/specs/ACTIVTEK_9960009.PDF The installation per se is rather easy, but complicated by the extremely compact size of the system in my apartment. The info in the pdf says to mount the air scrubber past the air...

    I know there are DIY ductless heat pumps available, but I'm looking to retrofit a ducted system into the space designed for a downflow furnace in a manufactured home. I haven't seen any advertised DIY systems that are designed to mount the air handler in a downflow orientation. Even the MRCOOL...

    Hello: I need an air handler and a central a/c unit. It's a 900 sq foot space. I don't need heat - the floors are heated. Can I use a regular furnace, without connecting to gas? I was looking at the Goodman furnace and a/c packages available on amazon. What is recommended. What is my least...

    I have a Unico Series M air handler with a hydronic heating coil, 24V control circuit with Therm-O-Disc time-delay relay (no control board). When the thermostat Fan switch is turned from Auto to On, I see 24 volts move from the blue to the green terminal (measured from yellow as Common) and the...

    Hey all. Yesterday I started having an issue out of my E3EB-015H. We noticed after being gone all day that the blower motor was not running in the air handler. There was quite a bit of heat that had built up inside the wall compartment that the unit is in. No breakers were tripped and nothing...

    Hi All, So I need some help with my heat pump. Right now the outside condenser is not turning on in either heating or cooling mode. A few days ago the low voltage 3A fuse on the control mother board popped and I replaced it. It popped once more about 30 minutes later, so I checked all...

    I have a issue heat kit calls for 1 circuit of 60 amps and no other circuit and it has a Molex at the unit to the heat pump. Do I no longer need to circuit breakers for the air handler and it's heat strips? I'm trying to help a family member keep her kids warm and do not have my laptop but I can...

    My HVAC is a heat pump system, the air handler inside is a Goodman aspf183016ea. The whole system/house is about 3 years old, and is all electric. I recently moved into the home and noticed that the air handler blower would continue to run even when the set temp was reached, whether heating or...

    We had a new Mitsubishi Mini-Split system installed in our house this summer consisting of a central air handler to replace a gas furnace, plus a wall-mount head in the master bedroom on the 2nd floor. (Details at the end). The air handler and the wall-mounted head each are controlled by an...

    Hello All, few days ago we replaced our entire Central AC unit. New Heat Pump and Air Handler. Older unit was over 12 years old and finally had Freon leak in the evaporator coil. We went with Silver 14 Heat Pump (2.5 Ton) with matching Temp4 Air Handler. Most folks told us key to long lasting...

    This Nordyne Electric furnace mystery has me stumped. Hoping one of you can help figure this thing out. The heating elements seem to work just fine. The blower motor wasn't coming on at all, even when switched to "manual" at the thermostat. I could jump across contacts on the control...

    Good evening all! Last week I came home from work to a happy wife all too happy to let me know the AC was broken upstairs. I went up and started checking things out and found the evaporator coil completely frozen up. I turned the unit off and let it thaw overnight and went back to...

    I recently had an American Standard TAM Air Handler installed. One edge of the front panel on my air handler leaks a noticeable amount of air. The installer tells me that this is normal. That does not seem correct. We paid to have all duct leaks sealed and now the air handler leaks. Is this a...

    I have a gas furnace with hydronic heating system using baseboard pipes on my first floor (Zone 1) and a heat exchanger in the attic (Zone 2) that is used for forced warm air throughout the entire home. Zone 1 works without issues. Zone 2 seems to be behaving strangely. Here is a typical...

    I'm new to the heat pump game but so far I've did pretty well. I have all the electrical wired correctly and ran the line set but I'm stuck in the final stages of the install. I've noticed that there's a piston inside the opening where the liquid line set is suppose to go. Am I suppose to remove...

    I have a Lennox air handler (pending installation) and my contractor brought a platform box for it, which is roughly 2x2x3 and both returns go into it as the air handler's air intake is in its bottom. But the sheet metal box he brought has no framed reinforcement inside it, i.e. it is just a...

    The fan motor only works when the cover panel is removed... not sure what the issue is. The motor sounds weak when it starts up, could it possibly be a relay? I honestly have no idea. It's a 1985 TRANE model. I would appreciate any input. thank you

    I have a 4-ton Lennox XC14. It is 4 years old. I live in Oklahoma City in a house I purchased Feb 2011. Last year, even during the extreme heat, the unit kept my 2000 sqft house nice and cool from 72-74 degrees. This summer it's not going below 77-78 in the peak heat hours, which is strange...
