Should I get a new furnace?

Its not...its a power sucker...I can guarantee that..

So..the coil was kinda hacked in...shame..

When you match the AC to the air flow capability of the new furnace, you get your best bang for the buck. Todays newer systems are designed to work with matching units. Period. You get your best savings when the units are matched and mated correctly to insure that every dime being spent to run the equipment is not being wasted. On a 10 year old furnace, it should need minimal work, if its been maintained properly over the last 8 years. If not, chunk it as well, and find a company that will service the things once they install them, and put your comfort first... The largest worry here, would not so much be the furnace, but matching the A coil, and the new AC unit are a proper match, and of course, mached to the airflow of the furnace.

Just went thru this same situation. We went ahead and had a new heat pump and backup furnace installed. So far, we are real happy with both. Have only had the furnace on just to make sure it works. Our electric bill has really dropped with the new heat pump.

Depends what kind of old furnace. Many of the ones from ten years ago were really great. Some were old klunks.

What did your furnace guy say? I'm betting he says to replace it and pay him.

I'm thinking that if your heat exchanger rots out, it's going to be a PIA to put the coil on a new furnace and redo the sheet metal work. But the savings in gas surely won't pay for the new furnace.

So, it's a coinflip. Rough change out, versus more cost now? Me, I'd likely keep the old one as long as it lives.
