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 tune-up in Spring Lake Park is $129 for one furnace or one air conditioner, $219 for both on one visit. We clean, test safeties and combustion, check airflow and refrigerant, and tell you what is wearing before we leave.
Spring Lake Park houses have been updated by several owners, and the tune-up works around what they left behind. Where a 1980s basement remodel closed the furnace into a closet, we check combustion air and clearances along with the burners and safeties. In an addition, we measure what actually reaches the room at the register.
On the cooling side, central air added to heat-only ducts leaves the coil marginal on airflow, and the blower tolerates little added resistance. That is why we check filters closely: a clogged one, or a high-resistance filter fitted to a basic blower, can freeze the coil. Mature trees shade the 1960s roofs but drop cottonwood fluff and seeds into condensers, so the coil gets a rinse. Townhome condensers get a check of pad level and clearances.

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.
Often it hurts. Basic trunk-and-branch ducts from the 1960s have little spare capacity, and a restrictive filter adds resistance that can overheat the furnace or ice the AC coil. At the tune-up we measure static pressure and tell you what filter your system tolerates. If you want allergy filtration, a media cabinet is built for that.
Sometimes, but usually it is the duct. The tune-up confirms the furnace is delivering its full output, with a clean filter and blower. Then we check what the addition gets: one supply tapped off a branch is common, and sealing it, insulating the crawlspace or adding a return path usually helps. A small ductless heat pump is the fallback.
