Heating and Air


I have 900 sq ft that needs to be heated and cooled. i do not have access to natural gas so I am assuming a heat pump is going to be my best bet
I have seen 2ton units on Ebay for appt 1500-2000 is that what i can expect to pay and how much can i expect for the ductwork? 5 or 6 registers?

Heat Pump is not efficient if you are on a very cold area.

Ebay prices don't mean anything when you buy a system from a contractor. What a contractor wil charge for an entire system is dependent on that house and contractor.

Care to back that up? OP has no gas available so lets say electric is the only option. Show me a heat pump that has a COP of 1 at 32 degrees.

I have dual fuel heat pumps in, that the heat pump heats the house at outdoor temps of 20F. And the gas furnace only comes on for defrost at 20 or above.

And yes, at 20F its still cheaper for those people to heat with the heat pump instead of the nat gas furnace.

Heat pumps are misunderstood by people that live in warm climates, or don't work on them.

JJ you need to educate yourself a bit better before making some comments or you are going to get shot down/embarrassed soon.
They are efficient well below 32 F.

Read up about the theory of heat pumps

When it gets to the point of giving wrong facts/mis-information to the original poster someone has to step in.

In the old days(oh no, not another in the old days story) LOL...

The terms/words of endearment(said out of ear shot of the customer) that the journeymen would use when I(ah I mean an apprentice) would tell someone how something works and of course be an incorrect explanation, are not allowed to be posted on this site.

It's one thing to be gung ho and try hard and have a good attitude but a fella can get himself hurt or electrocuted or damage something if he does not know what he is doing and thinks he does.

Yah, the good ole days (isn't that the first thing they taught you in school dumb azz is how I remember it, no time was wasted on subtleties)

What scares me about JJ is that he is going to get electrocuted the first time he sees a slow running condensor fan with a grounded compressor or other dangerous situations and marches into them naively. HVAC can be deadly if a guy starts thinking he knows stuff and doesn't. Pretty hard to learn it over the net or self teach yourself so working for a company to get started is necessary. A newbie needs some backup to call and not be afraid to ask questions when seeing something out of the ordinary.
