When I bought this house 5 years ago, it had the "original" gas furnace. The house was built in 1964. A 30 year old furnace???? Yup, it sure did look like it, too, lol.

We got one through Sears. But we got a whole system: new furnace, central air, and accessory whole house humidifier. New electronic temperature control thermostat. THAT whole thing ran about $6000, 5 years back. WORTH EVERY PENNY!!!!

You can get the gas furnace through Home Depot as well, I believe.

Make sure you have the City Inspector view and sign off on the installation; we don't want to be reading about you and family dying from faulty installation which leads to carbon monoxide build up in the home! Just had a family of 3 die of that here in Providence, RI, 2 weeks back. So sad.

And be sure to put new batteries in your carbon monoxide detector right after the install is completed, just in case. (If you don't have one, GET ONE!!!) Heck put in new batteries today!

As it IS working (all be it not too well) take some time and get 3 estimates. Talking with different companies you learn SO much! And things have changed since you put that one in 13 years back.

Also check with your gas company. Most offer a rebate if you select an Energy Star rated unit. Not all of them are efficient. If I remember, we had a choice from Sears, you know the "Good Better Best" type of thing. Only the BEST qualified for the rebate. The "GOOD" one is only 80% efficient, and you will definitely lose the savings in yearly heating costs over the life of the unit. You should be able to find a rebate program from you gas company on line if they have one. Check their web site!
