Comfort Gas Furnace
Condensing gas heat at a sensible price point.
The best heating system for a house in East Tennessee depends mostly on what fuel is available at the meter and how cold your particular pocket of the valley gets.
Where natural gas is available, a high-efficiency condensing furnace is hard to beat for raw capacity on a cold night — and pairing it with a heat pump as a dual-fuel system gives you low-cost heat through the long mild stretches and full furnace output in sustained cold.
Where gas is not available, modern heat pumps have improved considerably since they earned their reputation. Cold-climate models hold useful output well below freezing, and they cost far less to run than electric strip heat, which makes them the usual answer for homes out in the county with no gas at the road.
Furnace efficiency is measured in AFUE — the percentage of fuel that becomes usable heat. An 80% unit sends a fifth of what you buy up the flue; a 96% condensing unit sends almost nothing.

How to choose
Start with the fuel you have
Whether natural gas reaches your road, and how the house is heated today, narrows the choice quickly.
What do you have at the house?
Natural gas at the road
A condensing furnace, or dual fuel
A condensing furnace is hard to beat for raw capacity on a cold night. Pair it with a heat pump and you also get low-cost heat through the long mild stretches.
Hybrid heat
No gas at the road
A cold-climate heat pump
It holds useful output well below freezing and costs far less to run than electric strip heat, which makes it the usual choice out in the county.
Heat pumps
Radiators or baseboard
A gas boiler
A boiler supplies hydronic heat to radiator and baseboard systems.
Where the gas you buy goes
80% AFUE furnaceNon-condensing. Vents through the existing chimney.
80% heats the house 20% up the flue
96% condensing furnaceVents through PVC and needs a condensate drain.
96% heats the house 4% up the flue
AFUE is the share of the fuel you buy that becomes heat in your house rather than going up the flue.
What to look for
What matters when you choose
Fuel type matched to what is available
Load-calculated sizing, not nameplate matching
Dual-fuel where it makes economic sense
Venting and gas piping brought up to code
Combustion tested on every installation
Temperature rise verified against specification
The equipment matters less than how it is sized and installed, and that part is our responsibility.

Common questions
What is AFUE?
Annual Fuel Utilization Efficiency — the share of the fuel you buy that becomes heat in your house rather than going up the flue. An 80% furnace wastes a fifth; a 96% condensing furnace wastes almost nothing, at a higher purchase price and with different venting requirements.
Can I put a high-efficiency furnace in an old house?
Usually, but the venting changes. Condensing furnaces vent through PVC rather than the existing chimney, and they produce condensate that has to drain somewhere. Both are solvable; both need to be planned rather than discovered on installation day.
