Furnace & AC Maintenance in Mound, MN
A furnace or AC tune-up in Mound starts at $129, and both together are $219. We test and clean each system. In converted cabins, closet furnaces get a combustion-air and crawlspace-duct check.
Tune-ups in Mound homes
Mound's converted cabins put the furnace in a closet, so the tune-up starts with combustion air: a bath or kitchen fan can pull against a furnace that draws from the living space. We check combustion, draft and the vent, and take a carbon monoxide reading. Ducts run through vented crawlspaces lose heat before it reaches the room, so we look at joints, insulation and moisture, and we check the condensate drain, since lake humidity keeps the AC running from June to September.
Homes still on a gas wall furnace get the burner and venting checked, and electric baseboard homes get a safety look at the thermostat and the heating elements. Ductless systems get the filters and coils cleaned, which keeps mold from building in the coil. Shoreline homes lose heat through their floors, so we point out vented crawlspaces that would benefit from sealing. On the AC side we clean the coil and check the charge, and condensers placed close to a property line get a clearance check.

Tune-ups in Mound: questions
Why does the furnace in a small Mound house need combustion air checked?
A closet furnace in a small house often draws air from the living space. When a bath or kitchen fan pulls that air out, the furnace can burn poorly or backdraft. We check the air supply, the draft and the flame, take a carbon monoxide reading, and tell you if the closet needs an air opening.
Should we have the crawlspace ducts checked in our Mound house?
Yes, every few years or when rooms run cold. Ducts through a vented crawlspace leak heat, collect moisture and can grow mold if not sealed and insulated. We look at the joints and insulation during a tune-up and quote any repair in writing.
