I just went Heat Pump / Duel Fuel on Long Island
The old AC unit was on its last legs. The Heat Pump did not cost much more than a new A/C unit. You will need to spring for a new coil either way and it is well worth it.
I am very happy. The house has been the coolest it has ever been this summer and I am stoked about not having to buy Oil this winter. My oil burner will only be kicking in at 20* or colder (COP will be about 2.49 at 20*) otherwise the HP will do the job. With oil at these levels I could save as much as 1,200 a year, even at 21 cents per KWH that LIPA is jamming us for out on the Island.
Like beenthere said "You will be starting a trend in your neighbor hood.
When I tell people I am almost totally off oil their eyes go wide.
The right to brag about your new heating system is not a reason to buy a new system, but I tell you, people will think you are the sharpest home owner in all the land.
Of course the guys on this site will always think we are just knuckle head home owners. Tough but fair
Keep these guys on the site up to date with the work that goes on. This site saved me huge when the installers tried to use a closed coil as a transition elbow UGLY. They came back and did the right thing, this site was the 1st line for defense from getting shafted.
Best of luck.
