furnace run time ?

frumdogg

Fix'n it:

I'm with you on this thread, I just had a high efficiency unit installed (95%) and it seems as if runs more than my old unit (78%). My home was built in the early 90s.

I've been watching the gas meter every few days and comparing my bills with last year, and I am using about the same amount of gas. Any one here able to tell me if this is to be expected?

Nobody can give you anything even resembling an accurate answer to that question Way too many variables

I'm sorry. 95% efficiency 105k btu in 1900 sq foot home. Runs around 4-5 times an hour for anywhere from 5-10 minutes.

This nowhere near resembles an accurate statement.

what soecifics would be of benefit? no need to be rough

Type of home. Outdoor temperature. Time of day. Sun shining. People in the home. Ductwork. Filter. Setpoint.

How big was your old furnace?

105k for a 20 year old 1900sqft house sounds excessive....where are you located?

My 2000sqft house built in the same time period only needs 35k down to 18F.

Fix'n it

yeah. so surrounding items that have heat in them, don't effect what the thermometer is reading = it is reading only the air temp.

furnace = 70degrees it turns on. 74 degrees it shuts off.
