New heating system advice.

Posted by crice01 (My Page) on

So I bought a new home in WV six years ago. It came with a 57K btu propane heater, which heats rather well and a 10 Seer 3 ton Central AC. However, the price of propane has jumped to $3.10/gal and our estimated heating cost for next year are over $4k. Cost of electric in our area is .095/kw.

After crunching a bunch of numbers I have settled on a Goodman 3 ton 2 stage 16 seer/9.5 hspf system. The question I have is: the old unit was rated at 57K Btu and the Goodman is only 36K Btu, is this going to heat my home or do I need to be looking at a bigger unit?

Thanks.

Tell us the brand and model of the furnace.

More than likely, your furnace has a three ton blower rating. This needs to be confirmed.

If true, you can not go higher than a three ton HP condenser.

Also, you can not go to a high eff HP unless the blower on furnace is var speed or has the high eff X-13 blower motor which it probably does not have.

If above is correct, you would be just as well off to stay with a good 13 SEER HP condenser with matching evap coil.

You will also need a dual fuel thermostat and possibly an outdoor sensor.
