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.

A Savage tune-up is $129 for one furnace or one air conditioner, or $219 for both. We clean, test and measure, check drains and pumps, and tell you plainly what is worn.
Most Savage work involves two-stories, split-entries and townhomes from the late 1980s through the 2000s, and finished basements are common. Many have a condensate pump beside the furnace because the floor drain is across the room, so the fall visit includes testing the pump and float and flushing the line. We also clean the flame sensor, test the igniter and check the PVC vents.
Air conditioners installed before 2010 in these homes generally use R-22, which is why the spring visit leans toward leak checking and a candid report on remaining life. Cottonwood fluff from the river bottoms clogs condenser coils in June, so we wash them. On walkouts with a wall of glass, we also check whether the thermostat location is hiding an overheated upstairs.

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.
We test it as part of the furnace visit. That means pouring water into the pan to run the pump, checking the float and discharge line, and cleaning the trap and tubing where slime builds up. A pump that runs constantly is usually worn or is fighting a clogged line. A replacement is quoted before we do it.
A tune-up can show how it is doing: a coil cleaning, a capacitor test and a charge check. R-22 is no longer produced, so a leak turns into a replacement discussion rather than a top-off. The tune-up gives you that assessment, so you can plan the replacement instead of facing it on a hot day.
