It was due to happen sometime, the blower motor died on my 20 year old
3.5 ton GE heat pump. I'm planning to switch to natural gas because
we like the warm air feeling of gas heat and we had the gas line
plumbed into the area already. The installer will only need to add
the PVC exhaust pipe to complete the conversion.

We've owned this house in Maryland for 7 years, and we plan to stay
here indefinitely, so we want to install a reliable efficient system.
The full system will cost a little over $8000 so I want to be sure I
do this right.

The company is recommending the Carrier Infinity 96 Gas Furnace

and the Infinity Series Central Air Conditioner (21 Seer)

Does anyone have experience with the Carrier Infinity products? Any
recommendations for a nice system? Should I look into buying the air
cleaner add-on, we have hay fever in the spring and fall?

I have another company coming out on Monday to quote a Trane system.


Where do you live??

Have you considered a ground source heat pump??? Installing a 3.5ton
gshp would not cost an arm and a leg more than what you are
considering. check out WaterFurnace and ClimateMaster. EER is running
in the 27-30 range with COP of 5.0 (5x more efficient than electric
resistance)

Unlike your 20 year old GE air source heat pump, you are not likely to
need a backup heater, but these two companies offer it if you want/need
it. I correspond with folks in Quebec who have a 2 ton gshp and they
don't need backup heat until the outside temp goes below -20F and stays
there for more than 48 hours.
