It would aid in dehumidifying in thee summer months.

 

Rarely in California does anybody use the fan by itself....

 

I'm in western pa. I have a 2 story house with a finished attic. I'm replacing a 25 year old system. Both ac and furnace. House is about 2000 sq feet. That does not include the attic. The attic has vents but no returns and has never been able to cool itself without additional windows units. Our 2nd floor bed rooms have been havening trouble as well and we have had window units in them for as well.

I'm still unsure what I should do. Keep the current thermostat or upgrade to the trane one that can control the fan speed?

And if I do upgrade to the trane thermostat do I want the installers to not enable any automatic fan speed ramp up and let the thermostat handle it?

Thermostat is on the first floor.

 

New ac is 3.5 ton trane xr 14 seer. Replacing a 25 year old 3.5 ton lennox unit and a lennox pulse 21. The pulse still works but the ac has run out of refrigerant the last 2 years , and has had trouble starting in previous years.

So which thermostat should I go with? Installer says nest will be fine but I'm worried about not using all the features of the system.

 

I'd go with the Trane thermostat.

 

I have an S9V2 in my house and the Trane Stat as well, zero problems. It is WiFi capable but I don't use that feature.

JMO; a Nest Stat is like shingles, I wouldn't wish it on anyone...
