I'll try to keep this short.
I have an 1000 sf 2nd floor condo in a 3 story all-brick building with concrete floors. I have a Carrier Day and Night electric furnace/AC inside a utility closet (from 1978 - original to the house) and a fairly new 10 seer compressor in an external wall.
The house is well insulated except for a few drafty windows which I plan on replacing. When the outside temp is above freezing, the heat rarely runs at all. If the temp is below 30 as we've had in NYC for the last month, the heat will run in spurts of 5 minutes on, 10 off, 5 on etc.
I also haven't had a chance to have an HVAC tech look at the unit since I moved in due to time and $ issues, I've just been running it as-is. I plan on getting it looked at and cleaned out in a month.
I know heat pumps are highly recommended, but would the high cost of installation pay off in my situation? Or am I better off keeping my current one running the best I can until it dies?
For comparison sake, my electrical usage has been:
- December 2100 kwh ($390)
- October 853 kwh ($185) - temps were very mild that month
- July 1103 kwh ($266)
