Furnaces

Gas furnaces sized for the house, installed with the venting done correctly.

North Carolina winters are mild enough that furnace sizing gets skipped, and oversized furnaces short-cycle their way through the season. We size to the load and treat venting and combustion air as part of the job, not an afterthought.

What to know before you buy

A cracked heat exchanger is a safety issue, not a sales opportunity. If we find one, we tell you and show you.

Furnace and heat pump combinations can be set up as dual fuel, with the heat pump carrying most of the winter.

Sizing and model selection

Published ratings describe the equipment, not your house. We size furnaces against the building's load, ductwork and existing equipment before quoting a model, so the numbers on the spec sheet actually show up in your comfort and your bill.
