Furnace & AC Maintenance in Montrose, MN
Montrose tune-ups are $129 for one furnace or AC and $219 for both, with capacitors, contactors, the igniter and the inducer tested before the first hot week.
Tune-ups in Montrose homes
A Montrose tune-up is built around the age of the equipment. Houses from the 2000s building run now have condensers and furnaces of the same vintage, so the visit tests the capacitor, contactor and fan motor, cleans the coil and measures the temperature split. On the furnace we test the inducer, igniter, flame sensor and pressure switch, check the condensate trap on 90% models, and read static pressure at the return, since an undersized one is common here.
Split-levels get one more stop at the basement trunk lines, where the manual dampers get set for the season. The few older frame homes in the core platted in 1878 that still vent through a chimney get a draft and carbon monoxide reading. The newest streets, with young equipment, get a lighter visit and a written record of the model and serial numbers for warranty paperwork.

Tune-ups in Montrose: questions
Why do so many Montrose air conditioners fail in the first hot week?
Many were installed in the same few years, so the capacitors and contactors are the same age and wear out together. Heat stresses them, and the unit hums without the fan spinning. A tune-up tests those parts before summer, and if one is failing you can ask for the repair and replacement numbers in writing before the first hot week.
Does a Montrose tune-up check the return duct size?
Yes. Many 2000s houses have a return smaller than the blower needs, which raises static pressure, heats the exchanger and trips the limit switch. We measure static pressure at the furnace during the tune-up. If the reading is high, we show you the number and quote return work as a separate line, so you can decide whether to fix it now or at replacement.
