Efficiency?

Our home has the original forced air gas furnace from 1989, and we are thinking of replacing it. The unit with 93% efficiency will cost $1,000.00 more than the unit with 80%. Is it worth the difference?

Efficiency

I am assuming that someone will come along and tell you to calculate the amount of annual savings with the more efficient unit. If you plan on staying in the house, you will need to know the annual savings of one system versus another. You will also need to know the improvement value of your investment when it comes to resale value? How long do you plan to remain in this residence?

Unhappy Forget about resale

You need to get ALL the savings back in energy savings.
Most people only ask how old a funace is when purchaing a house, a 93% will bring little if anything at closing time.
I personally would run the old unit until something expensive breaks on it.
If you live in a cold climate the 93% can pay for itself quickly.
The quickest "payback" is to find a QUALITY contractor to correctly size the new unit (most likely will be smaller than the old one) and install it.
A good professionally done installation is worth every penny !!!
