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.

Tune-ups for New Hope homes run $129 per furnace or AC, with $219 for both together. A tune-up covers cleaning, ignition and safety tests, a blower and return-air check and a carbon monoxide reading.
Almost every New Hope house is a split-entry or rambler from the late 1950s to early 1970s, and many pull return air through panned joist cavities. That makes a tune-up here more than burner cleaning: static pressure, the return path and the blower's workload all get measured. A dirty filter on top of a leaky return is a common cause of a noisy furnace.
The split-entry also has two climates. The lower level sits half below grade and runs cool and sometimes clammy, while the upper level under the attic heats up in summer. In spring we check the condensate drain, clean the coil and tell you which supplies to close partway. Where a lower level has been finished, we also look at where the added supplies and returns run.

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. The upper level of a New Hope split-entry sits right under the attic, and where the attic insulation was never topped up, the bedrooms heat through the ceiling on a sunny afternoon.
A filter that is too restrictive or seated crooked can leave the blower straining or let air whistle past the frame. Check that it is the right size, sits flush and faces the right way. If the noise stays, the cause is often a leaky or restricted return, which a tune-up finds by measuring static pressure. We also check the blower wheel and bearings.
It helps if a dirty filter or blower is limiting airflow, and we also look at damper settings and returns. But the stair landing lets in cold air and the family room is half below grade, so balancing, a return in the lower level and a thermostat sensor often matter more. We tell you what we measure.
