Fall Furnace Checklist: What to Do Before Winter
A fall furnace checklist for Minnesota homeowners: filter, vents, drain, CO alarms, humidifier, propane and a test run, plus what a $129 tune-up adds.

A Rosemount furnace or AC tune-up is $129, or $219 for both on one visit, for newer homes with PVC-vented furnaces and condensate drains. It covers cleaning, testing and measuring, with the results explained.
Rosemount is mostly newer housing, and that changes what a tune-up looks at. Homes from the last twenty-odd years are tight, with 90%-plus furnaces, PVC venting and an air exchanger, so the fall visit covers the condensate drain, the intake and exhaust terminations and the exchanger's filters and balance. Terminations that sit low or face open fields can frost shut or drift over, so we note whether they need raising.
The first-generation furnaces in 1980s and 1990s subdivisions are due for a heat exchanger inspection, igniter test and carbon monoxide reading. On rural parcels near UMore Park, propane furnaces get a burner and regulator check, and heat pump outdoor units on exposed sides should sit on a stand above the drift line. Spring visits matter in the newer neighborhoods because young trees give little shade: condensers on the sunny side work hard, so we clean the coil and check refrigerant charge and airflow.

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.
Yes, once a year. We check the filters or core, the airflow balance and the controls during the fall furnace tune-up. A dirty or unbalanced exchanger in a tight house can leave air stale or humidity high. If it needs a part or a deeper cleaning, we quote that separately in writing.
A tune-up checks the vent and condensate drain and finds frost or drift problems, but the cure may be relocating or raising the termination, which we would quote first. It can also be a blocked pressure switch or drain. We clean the pipes and test the furnace, so we can tell which one it is.
