How often should a gas furnace cycle on and off for those living in
colder climates (Canada)? I have noticed that during winter, when
maintaining the temperature of the house steady, my furnace tends to
turn on every 5-10 minutes, staying on for about 10 minutes each time.
I find this to be a little to frequent. I have the specs from the
previous owner, and the furnace is 13 years old, 72,000 BTU (82%
efficiency) in a 1200 sq foot 2 story home. I am thinking about
getting it replaced as it had 3 separate problems this year with
components breaking down (hot surface igniter, blower, flame sensor,
etc.) and am wondering if perhaps it is oversized (i.e the frequent
cycling) and I should get a smaller model?

How long do gas furnaces typically last anyways? I have read on the
Internet that gas furnaces can last 20-25 years, but I'm wondering if
perhaps that is reflective for warmer climates where furnaces aren't
used as much. Over here the furnace is probably on from early October
until mid-May.

Hi,
It all depends how well your house is insulated.


Wrong. Seeing as you don't know what you're talking about,
STFU.

I have 2700 sq. ft. 2 storey house with 100,000 btu mid-efficiency
furnace. it cycles about every 20 minutes in coldest days in winter.
Those are normal wear and tear items you replaced. The blower some times
needs oiling for the shaft bearing. I think your furnace has
few more years left.


How in the hell do you pretend to know ANYTHING about it ?
Ever seen it ? Ever serviced it ? EVER EVEN BEEN IN THE SAME ****ING
BUILDING WITH IT ???

No ???? Then STFU.


I always keep HSI as a spare.
