    Moved into a property with two old thermostats (one upstairs and one downstairs - one furnace and two zones). They are ancient but the furnace company said they can be replaced and that it’s a 5 wire thermostat. I’m not totally sure what this means… could I replace it myself with a wifi version...

    Hoping an expert here can help me out with an issue. I have a Goodman GMV9/GCV9 furnace and a General Aire 1042-L humidifier. When I went to replace the filter for the humidifier, I noticed it was dry and had no water going to the humidifier. My first initial thought was that the water line may...

    Carrier Furnace Model:58SXC060-100GG When I power up my furnace it will run a full heating cycle and stop but then it won’t start a new heating cycle when the thermostat calls for it. I was getting a Pressure switch error code so I took the tubes off and blew threw them without any...

    Hello I would like some idea about a problem we are having with our electrical furnace. If the furnace turns on for heat, it will run for a bit, let's say 20, 30 minutes, then the breaker will trip. If I feel the 125amp breaker, I can feel that its pretty hot. If I run the fan from the...

    Hello everyone. My furnace is not heating as it should. I've seen other posts mention their system only runs without the inducer cover on but could not find a definitive answer for a fix. This is also the case with my furnace. I've replaced the limit switch, flame sensor and the air filter. All...

    Short and sweet - I'm replacing my hvac system and am not sure what I should get - Single stage or two stage? I got quotes for both and the two stage is $1500 more. I figure that would have to save me about $15 a month over 10 years to be close to worth it if the only benefit I'm going to see...

    I went away for a week and shut the gas off to the house. When I can back, the furnace lit up only briefly and then shut down. After having an HVAC person out. I was told the switch and control board were bad. I just installed a new switch and the problem remains. I can provide a light suction...

    Good day to all. I have a nordyne g6rc furnace that I have replaced the igniter, pressure switch, and flame sensor, as well as the thermostat, too, because the ignition sequence would not complete. That issue is fixed. However, within days, I noticed that if the furnace hasn't run in a while, I...

    When the outside temperature gets cold in the early AM, the gas furnace kicks on for just a second. Sometimes this happens over and over and I turn it off at the breaker. I thought it was a short in the wiring so I disconnected all the thermostat control wires at the furnace control board, but...

    Anyone with a Honeywell ST9120U board who can tell me what the component value is for the components RV1 and U1 is on the board by the 5 Amp fuse. I just need the numbers off of it so I can get replacements. I connected something up incorrectly and blew them both off of the board.

    When I turned on my heat last couple days, the HVAC would kick on and then off again. When I removed the panel, there was water leaking from the exhaust tube (where that connection point is). It is a high efficiency HVAC (Lennox 5 years old). My guess is that one of these 2 areas is clogged...
