The overview

What it is, and why it matters.

A furnace reaches the end of its life when repairs pile up, efficiency drops or safety is in question. We size the new unit to your home's heat loss, check venting and combustion air, and recommend a model that fits your comfort needs and budget.

Installation includes removing the old furnace, new venting and gas connections as needed, thermostat setup, a combustion and safety test, and a walk-through of filters and controls.
