Our heating and A/C system is about 17 y.o. is nearing it's end. The A/C professional said it's not worth fixing it - just let it die and buy a new system. It can go any day and I would like to know what system I should go with when the time comes for a decision.

We live in PA (Philly suburbs) and here's what we have now: heat pump with gas backup. It switches to gas only when it gets very cold.

I would like to know what is the best system in our climate? Should I go with the same set up - heat pump with gas backup or should I get a gas furnace and put in an air conditioner? Or should I go with electric furnace and an air conditioner?

You thoughts and advice is greatly appreciated, thanks!

 

Go to http://www.warmair.net there you can compare fuel cost for where you are. This should tell you how to go.

Generally, a heat pump with gas back-up is about as cost efficient as you can get with conventional equipment. The trick is finding the temerature at which it is cheaper to run the furnace than the heat pump & having the controls to shut down the pump & turn the furnace on.

 

dual fuel system using 90% furnace and heat pump would be my thought, but ed's like will tell the tale
