Pentagon Air sizes every furnace to your home's actual heating load and installs it to manufacturer specs so you get safe, efficient heat from day one. ## When You Need Furnace Installation If your current furnace is over 15 years old and the next repair costs more than half a new unit, replacement is usually the smarter investment. If your furnace can't keep your home warm. common in older Bowie homes where the original 60,000 BTU furnace is trying to heat an addition that was built 20 years later. a properly sized new unit solves the problem. New construction and finished basements also need furnace installation. ## Our Furnace Installation Process We start with a free in-home estimate. We assess your home's heating needs, check existing ductwork, and recommend equipment options at different price points. Installation includes removing the old unit, setting up the new furnace, connecting gas and electrical, testing all safety controls, and running the system through a complete heating cycle.
