Should I go with a heat pump?
My central AC compressor bit the dust last night. I had a family friend come out to look at it and he said that I need a new unit (he is a lifetime HVAC person). My AC unit was/is from the early 70s, original to the house, so I expected it to go.
Anyway, I have a free central AC system coming to me, via my father, so I could replace this for only the labor. However, I have an oil furnace so I was thinking of getting an add-on heat pump and use the oil furnace (circa 2002) as supplemental heating. My question is, would it make sense to get this or should I just stick with oil? I am looking at both the resale value of the house and the running costs (mainly the running costs). At $3.80/gallon (in my area, PA, oil was about $3.70 at the end of the winter) and $.104/kwh (going up to $.15 in 2010) what would be the best choice? I am only heating 1200 ft2.

- Minimize the use of oil heat (use it as supplimental heat).
- Get a heat pump condenser w/matching indoor coil. They MUST be a matched set.
- Not go too crazy on SEER (14 max) because you are limited by the oil furnace air handler.
- Post the model numbers of the condenser and matching coil so we can tell you if it an ARI (American Refrigeration Institute) approved match.
- Make sure that the system is sized properly thru a heat gain/loss calc.
- Make sure that your duct work is sufficient.
- Remove your pricing from your post before one of the Moderators remove it.
with a properly sized HP and good ductwork, your decision is really a no brainer. in fact, it appears that HP with electric strip heat backup would save over oil.
Crunch the numbers on attached fuel comparison calculator.
OK, so you think the add-on heat pump is the way to go? He is going to be replacing the inside coil with one for the condenser. I asked if I had to replace the inside coil, if I just went with a new condenser, and he said no but he wouldn't do the job.
How do I calculate a monthly cost breakdown, the cost to heat my home?
Thanks a lot for the link! My duct work isn't insulated, it is from 1972, so it would need to be replaced I suppose. The good news is that all registers are on the floor and I only have one level so the runs aren't too long.

Reason: Clarification on ducts
what size is your existing AC condenser?
PECO give BIG discounts for heat pump,we have not an a/c unit in months!!
It's NOT the BRAND,it's the company that installs it!!!!!
