Furnace & AC Maintenance in Excelsior, MN
A furnace or AC tune-up in Excelsior starts at $129, and both together are $219. Boiler visits fall in the $129–$349 maintenance range. Boilers here run hard for weeks, so we check the relief valve, expansion tank and circulator before January.
Tune-ups in Excelsior homes
Excelsior has more boilers than most Lake Minnetonka towns, along with converted furnaces in old coal-era basements. For a boiler visit we check the burner and controls, the pressure, the relief valve for weeping, the expansion tank for waterlogging, the circulators and the venting. Those are the parts that fail in the first real cold, and a leaking relief valve or a circulator that will not start is easier to fix in October. We also bleed radiators when they need it.
Furnaces in these houses sit in fieldstone or block basements that wick moisture, so we look for rust on the cabinet and flue, check the condensate trap and test the draft. Converted gravity duct systems can carry a musty smell upstairs once the air conditioning starts, so we look at duct joints and the coil. High-velocity and ductless systems get filters and coils cleaned, and condensers squeezed between houses are checked for airflow clearance.

What does a tune-up in Excelsior include?
Each $129 visit covers cleaning, a safety and carbon monoxide check and a written report. Boilers, heat pumps and mini-splits fall in our $129–$349 maintenance range, confirmed when you book. Houses near the water take the wind straight off the ice on Excelsior Bay and St. Albans Bay, and a long lake winter finds every gap in 1890s window frames and balloon-framed walls.
Tune-ups in Excelsior: questions
What should be checked on an Excelsior boiler before winter?
The relief valve, expansion tank, circulators, pressure, burner and venting. A boiler that runs hard for weeks shows weak points quickly: a leaking relief valve, a waterlogged tank or a circulator that quits. We also look for leaks at radiator valves. Boiler visits fall in our $129–$349 maintenance range, and we confirm the price when you book.
Why does our Excelsior basement smell musty when the AC starts?
Fieldstone and block basement walls wick moisture, and converted duct systems carry that damp air upstairs when the fan runs. A dirty coil or a clogged condensate line adds to it. We clean the coil and the drain, check the duct joints, and suggest a dehumidifier if the basement stays damp.
