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.

In Brooklyn Park, a furnace or AC tune-up is $129, and both systems together are $219. A visit covers cleaning, combustion and airflow testing, and a refrigerant check on the AC, with a rundown of what is wearing out.
Brooklyn Park spans three eras of equipment, so a tune-up changes with the street. In the 1960s and 70s south end, we test heat exchangers and draft on chimney-vented furnaces and expect long cycles below zero. In the Edinburgh area, original condensers from the 1980s and 90s get the closest look at the fan motor, capacitor and coil.
North of 85th Avenue, builder-grade condensing furnaces are old enough for their first big repairs. We test the inducer, the pressure switch and the control board, flush the condensate trap and check the line to the pump, since a line running through a cold garage can freeze. We also confirm the PVC intake and exhaust sit clear of drifted snow. Near the river, cottonwood fluff clogs condenser coils each June, so a spring visit is the time to rinse the coil.

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.
At that age, the parts that start to fail are the inducer motor, pressure switch and control board, plus a clogged condensate trap. We test each, flush the trap and drain, and measure the temperature rise. Catching a weak inducer in October is cheaper than losing heat in January. Any repair is quoted before we start.
Late spring, before the first hot week, works well. We rinse the coil from the inside out, check the fan, capacitor and charge, and clear the drain. Cottonwood fluff in June can clog the fins afterward, and you can rinse the outside of the unit gently with a hose once it falls.
