I have a new home built in 2009.
This is our second winter with the Geo unit. Temperature last two days was -10 to -20.
Is it normal for AUX HEAT to run frequently in those temps ?
I live in Caledon, Ontario, Canada.
My home is 4800 sq ft and I have a 6 ton for basement/main floor and 3 ton for upper floor. 4800 is excluding the basement. its unfinished. I have rigid board on the block calls with R-5 rating. Didnt finish putting up walls yet with R-14 bats.
When the temp outside was -20 the system couldnt bring the temp up. It stayed at 21 , it wouldnt budge. I set my anticipator high to try to keep AUX HEAT off. It would go into HEAT 2 and continously run at that stage and never be able to bring the temp up.
Today I decided to let AUX HEAT run because my wife was freaking
I have the problem where I need to put in 2 small plug in heaters for my kids rooms 1.5Kw heaters. One in each room because they get cold upstairs in their rooms.
The ducting for 3ton unit runs within the attic. I havent checked if the ducting is insulated.
I noticed we use around 4700Kw of electricity in winter months. Does this sound normal? We dont have anything abnormal running except usual appliances besides that, and the two plug in heaters for my kids room. If the geo would work properly then I could get rid of those.
Our upstairs unit uses a York AHX36 air handler connected to the climatemaster system. Do you think 1200CFM is sufficient for our upper floor?
Any help would be greatly appreciated.
