Which brands do you install?

We install proven equipment from major manufacturers and recommend based on your home and budget, not on sales quotas. We will explain exactly why we suggest a given unit.

Should the ducts be cleaned when the furnace is replaced?

It is the best time to do it. A new furnace pushing air through decades of dust undoes part of what you paid for, we inspect and tell you honestly whether yours need it.

Can you replace an old oil or electric furnace with gas?

Fuel conversions depend on what service your home has. We assess what is feasible during the in-home visit and lay out the realistic options.

Is a bigger furnace better?

No, oversized furnaces short-cycle, heat unevenly, and wear out sooner. Correct sizing from real measurements is the single biggest quality factor in an install.

Furnace Installation & Replacement

A New Furnace, Sized and Installed Right

When a furnace is past saving, the install matters more than the brand on the box. An oversized unit short-cycles and wears out early; a sloppy connection to old ductwork wastes the efficiency you paid for. We measure your home, size the system honestly, connect it properly to clean ducts, and test the whole thing under load before we leave, with photos of every step.
