Furnace and a c running at same time.
Furnace and air conditioner running at same time.
If you have a gas furnace and it was in fact running flames coming out of the burners at the same time your air conditioner was running then call a hvac repair guy.
I felt the air coming out of the register and it was warm.
Pros to running fan on air conditioner continuously.
The furnace blower comes on automatically and only when the thermostat calls for heat regardless of thermostat fan settings.
Look for the terminal marked w normally there would be a white wire connected to w but the wire could be a different color.
The problem with running an air conditioner and a humidifier at the same time is the two appliances fight against each other in a way.
Less frequent starts and stops of the fan can reduce the stress from startup and potentially help extend it s lifespan.
So i checked on the a c and it was running.
Keeping the fan on creates a more even distribution of heating and cooling circulating the air if you have cold or hot spots in your house like a bedroom above a garage.
I just turned the a c on for the first time this year and i noticed that my house was not cooling.
If you switch it to manual the blower runs all the time to circulate air.
If it s on auto when the heat or the a c comes on the blower comes on.
Replace your furnace and air conditioner at the same time if any one of the above requirements is met which is about 70 of the time.
In the rv there are 2 blowers.
One for the furnace and the other for the a c.
I looked at the thermostat and it was set to 72 the room temp was 79.
