Having problems with your Air Conditioners ?

I have a Consolidated Industries gas furnace,

\015 This is the only section I could get to accept this post.I have a Consolidated Industries gas furnace, model USA 090 NH4R, serial 981218142. It was coming on correctly in the heat mode but sometimes the air would be hot and sometime it would be cold. I changed the thermostat from the old mercury style to a digital style. The unit did the same thing. The fan is coming on fine but the air is cold. Do I have my new thermostat wired wrong or where should I be looking to get the hot air?\015

Answers :

The digital thermostat must be programmed for GAS heat.
\015\012If the problem occured before the t-stat change and is still happening, the problem would be with ignition within the furnace.

Dear FixYa Experts, I am a new home owner. I have a Kenmore Air Conditioner (heat pump?, see more details below) with Lincoln Gas Furnace. According to the former owner, the heating system will start heat pump first when the temperature is above -15C and then turn on the gas furnace when the temperature drops below -15C. Recently, when I turn on the heating system, only the gas furnace was always running but not the Kenmore air conditioner. And our average temperature was always above +5C for

Twice in the last year, I have had a gas smell come from my Goodman furnace. In this last case, the smell of gas came through the duct work. There was not smell in or around the furnac itself. Some how it got into the duct work very quickly., Had tech check the unit and cannot find a leak. Everything (sensors, safety switches, etc) seems to work. Once you remove the gas then the unit seems to work fine.


Did the tech check to see that the heat exchanger does not have a hole of a crack in it...I have seen this and it is more common than you think....Make sure you get to the bottom of this as there is the danger of carbon monoxide poisoning...I would ... Goodman Air Conditioners

Hello, I have a Heater/Furnace problem. I have a Carrier 58RAV095-16 Natural Gas Furnace. My furnace keeps restarting it's heating process. Upon turning the heater on, a small fan will engage and run for about 60 seconds, then the fan turns off and the gas engages and the igniter clicks and you hear the gas combust and the flames spew out onto the heating rods(?) and after a minute or so, the big fan will turn on and begin circulating air throughout the house. Sounds all good so far? Well

My gas furnace is blowing cold air. I was told by gas company that it is due to a gas pipe leak. Is this true ? How will it be fixed? What problems can i expect in the future? The furnace is 20yrs old.


If the pilot light is on then it could be in the thermo coupler. If you don't know where to loon it is best to hire a professional. Gas indoors is no joke. Second is that a 20 yr old heater is pretty inefficient and a new one could be had for a littl ... Air Conditioners

I am trouble shooting a Bryant Hi-bred system that uses an air cooled heat pump with high efficiency gas furnace for backup and low ambient operation. How does the system decide whether to use the air cooled heat pump or the gas fired high efficiency furnace. It appears to be outdoor air temperature related, but I can't find the setpoint for it. The main zone Bryant thermostat appears to control the system, but it doesn't always bring the backup heat if the heat pump doesn't function.

I'm looking into replacing my 2 ac systems. They're working fine but 13 years old. They're 4 tons ac systems with gas furnace. I've got quote from local RUUD dealer using RUUD ac UASL-048JEC, RUDD gas furnace RGPE-07EBRQR and coil by ADP (RES066GE2ISB2722AD). Is it ok to mix ADP coils with RUDD ac system or should I insist on using RUUD coil?


This really shouldn't make a difference... the point of the coils is just to transfer a fluid/gaseous medium and transmit temperature differences via their surface area. I'm sure if the ADP part is cheaper, it will be fine to use. They're ... Air Conditioners
