In Ham Lake, a tune-up is $129 for one furnace or one AC, or $219 for the pair. We clean the burners or the coil, then test ignition, safeties and airflow; on open lots the furnace's side-wall PVC vent gets checked for drift damage too.
Ham Lake grew into a rural-residential city mostly after 1970, so the equipment ranges from 1980s furnaces on a second or third replacement to newer custom homes. Distance from the gas mains decides the fuel: natural gas where it reaches the road, propane where it does not, often paired with a heat pump.
The heat pump changes the spring visit: one that carries the house through fall and spring, and cools in July, runs far more hours than a plain AC, so we check its coil, defrost operation and charge before summer. In fall, the focus is the vent. High-efficiency furnaces breathe through side-wall PVC that snow can drift over on open yards, and a blocked pipe is a common cause of a furnace that quits on a stormy night.

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.
Both. The heat pump is best checked in spring, since it does the cooling and much of the shoulder-season heating, and the propane furnace in fall. A heat pump visit falls in our $129–$349 maintenance range, confirmed when you book. We check the controls too, so the furnace takes over at the temperature it should.
The tune-up covers the furnace and its gas connection: burners, ignition, safeties, airflow and the vent. The tank, regulator and outdoor lines are usually serviced by your propane supplier, so call them if the gauge or regulator looks off. Ask them to confirm the tank is topped up before a long cold stretch, then book the fall furnace visit.
