Furnace & AC Maintenance in Dayton, MN
Dayton homeowners pay $129 for a furnace or AC tune-up on one system, or $219 for both. We clean, test and measure, check the vent and drain on condensing furnaces, and list anything wearing out.
Tune-ups in Dayton homes
Dayton's housing splits cleanly. The 1970s ramblers and split-levels have furnaces that have been swapped out once or twice and central air added years later, so we measure airflow and check that the coil suits the blower. The much larger group is new construction: 96% furnaces vented in PVC, an air exchanger and builder-sized AC in their first decade. For those, we flush the condensate trap, test the pressure switch and inspect the intake and exhaust pipes, which northwest wind can pack with snow overnight.
Because houses keep going up across the city, dust is its own issue. Drywall dust loads a furnace filter within weeks and grading dust coats condenser coils next door, so we advise more frequent filter changes while building continues nearby. Rural lots still on propane get the gas connection tested, and heat pumps are checked for a stand above drift height.

What does a tune-up in Dayton 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 are still going up across Dayton, and a neighborhood under construction is hard on air conditioners.
Tune-ups in Dayton: questions
A neighbor is still building in our Dayton subdivision. How often should I change the filter?
More often than the label says, at least until construction nearby ends. Drywall and construction dust loads a filter within weeks, and a clogged one cuts airflow and strains the blower. Check it monthly and swap it when you see a gray surface. We look at the filter, blower and coil at the tune-up.
My Dayton furnace shut off after a snowstorm. Will a tune-up prevent that?
It helps. A 96% furnace breathes through PVC pipes, and drifting snow can plug the intake or exhaust so the pressure switch shuts the furnace down. We inspect the vent, trap and switch at the tune-up. After each storm, clear the pipes by hand and keep shoveled snow away from them.
