Thank you for answering my return air and static pressure questions in another thread. I have one other question for yall.
I will try and give you a quick overview of our situation.
This spring we bought a 7 y.o. 2600 sq. ft. L shaped ranch with a full basement in se lower Illinois. It has a Heil 125k btu, DC90 furnace with AC. Im am not sure what brand the AC is. This is our first winter.........man does it get cold in Illinois.
We had a local company come out to do the furnace service. The company came very well recomended by a couple neighbors. From what I posted in the other thread it looks like the guy did a great job. He left me with a lot of documentation on the readings he took and made some adjustments that he said should have been made by the company who serviced it last.
I asked if the serviceman had any advice for our first winter here. He suggested that we run the furnace fan continually. He said we would be more comfortable and it would help stabilize the temperature in a cold bedroom that is at the end of the house. (it helped a lot)
At first he turned the thermostat fan to on. He said I wouldnt be happy with that because it had the fan blowing on high. He went back down to the furnace and changed a couple wires so the fan runs slower. The thermostat fan is still set to auto but the fan is running. He has a note on the paperwork that he has the "Continuous Fan Speed" set at "medhi"
My question is can the fan speed be set to a lower speed? It is noisy and a breezy from the floor registers.
I called the company and they said my furnace only has 4 speeds and that the low speed is already being used by the AC and he can not set it so both the "Continuous Fan" and AC, both use Low speed.
Does anyone know if this can be changed?
Should I call a "Heil" only serviceman to come out?
The electronic board that he changed the wires on says Honeywell. Should it be a Heil?
