What a Furnace Inspection Covers, and Why Each Check Matters
What a technician checks on a furnace inspection in Minnesota, from gas pressure to the heat exchanger. It is part of our $129 tune-up, or $219 with the AC.

For Golden Valley homes, a furnace or air conditioner tune-up costs $129 each, and $219 covers both in one visit. Each includes cleaning, ignition and safety testing, an airflow and drain check, and a carbon monoxide reading, with findings explained before any repair is discussed.
Golden Valley's 1950s ramblers are the most common tune-up job: an 80% furnace on an original chimney, central air added later, and an addition at the far end of the ducts. We check the heat exchanger as far as we can see it, test the draft, and measure airflow to the added rooms, since those are the ones that run short. Wooded lots matter in spring. Maple seeds, leaves and cottonwood pack into condensers near Sweeney Lake and Bassett Creek, so we wash the coil from the inside out.
The mid-century modern houses around Tyrol Hills need more attention to the system type. Some have radiant heat in the slab, others a boiler, and many have no attic for ducts at all. A boiler visit covers pressure, expansion tank, circulator and relief valve, and ductless heads get filters and coils cleaned.

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. Boilers fall in our $129–$349 maintenance range, confirmed when you call 612-429-3465. We check system pressure, the expansion tank, the circulator, the relief valve and any visible leaks, since a failing radiant loop or tired boiler is a serious repair. We can't inspect piping buried in the slab, but we can tell you what the boiler is showing.
Have it done in spring, before the first hot week. Maple seeds, leaves and cottonwood collect on the coil and cut airflow, which raises head pressure and wears the compressor. We wash the coil, check the capacitor and fan motor, and clear the drain. If you can see leaves against the fins, book earlier.
