Calculated sizing, altitude-correct setup and a spotless install. Free estimates and financing for Westminster homeowners.
Replacing a furnace in Westminster is a fifteen to twenty year decision. Mostly 1970s and 1980s tract homes, with newer homes toward the north and redevelopment around Downtown Westminster. Westminster sits between Denver and Boulder along US 36, with large established neighborhoods and steady redevelopment. We bring a calculated, written proposal to every estimate, and we install with floor protection, clean venting and full commissioning before we leave.
We see plenty of 20-plus-year-old furnaces in Westminster's established neighborhoods, which makes honest repair versus replace math important.
We calculate the heating load room by room, check ducts and static pressure, and recommend a furnace sized to the home rather than copied from the old nameplate. On install day we protect floors, remove the old equipment, update venting and condensate drainage, handle the permit where required, and commission the furnace by measuring gas pressure, temperature rise and combustion.
At about 5,300 feet, altitude setup is not optional. A new furnace that is not configured for elevation can run hot and wear early. We set and verify every Westminster install against the manufacturer's altitude guidance before we leave.
