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 tune-up in Arden Hills is $129 for a single furnace or AC and $219 for both together. The visit covers cleaning, safety and combustion tests, airflow and refrigerant checks, and a plain report of anything wearing out.
Half of Arden Hills' houses predate 1974, so fall tune-ups here often start with a chimney-vented 80% furnace on its second or third round. We test the heat exchanger, run a draft check on the flue and make sure the water heater sharing that vent is drawing properly. A 1970s house also tends to have its original gas piping and duct layout under newer equipment, so we look at those connections too.
Spring work leans on R-22 air conditioners from the 1990s and 2000s. We check for refrigerant leaks and weak compressors and tell you plainly if repair no longer makes sense. In Arden Manor's manufactured homes, we check the direct-vent furnace and look at the crossover duct and belly wrap for tears. Near Lake Johanna, we watch run times and humidity, since an oversized AC leaves lower levels clammy.

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.
Often yes, as long as it is not leaking. The tune-up cleans the coil, tests the capacitor and contactor, and measures pressures, which shows whether the charge is holding. R-22 is no longer produced, so a unit that keeps losing refrigerant is usually better replaced than topped off. We will tell you which case yours is and quote any work before we start.
Yes. The furnace is cleaned and tested like any other, including the burners, the venting and the safety controls. Because heat travels through ducts in the belly, we also look at the crossover duct between sections when we can reach it, since a crushed or loose crossover leaves the far bedrooms cold.
