A fall furnace checklist for Minnesota homeowners: filter, vents, drain, CO alarms, humidifier, propane and a test run, plus what a $129 tune-up adds.

In New Brighton a tune-up is $129 for one furnace or AC, and $219 for both on a single visit, with vent routing and condensate checks. We clean and test the working parts, check vent routing and the condensate line, take a carbon monoxide reading, and set a humidifier or filter if you have one.
New Brighton is mostly split-levels and ramblers, so the furnace is usually in a lower-level utility room by the laundry. The fall visit reaches the burners and blower there, then follows airflow up to the bedrooms, since the top level runs warm and the bottom runs cold on one thermostat. If you have a whole-home humidifier, we clean the pad or replace it and set it for outdoor temperature, because sweating windows mean it is set too high.
Spring is about damp basements. Near the lakes and wetlands, supply ducts in unfinished ceilings can sweat, and the AC rarely runs long enough to dry the lower level. We clear the condensate line and look at duct insulation. On 1970s and 80s condensers we check whether the unit still runs R-22.

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 service it with the furnace: clean or replace the pad, check the water feed and drain, and confirm the humidistat setting. We lower it as the outdoor temperature falls, since high humidity sweats older windows. We can tell you what the humidifier needs when we are there.
The AC mostly cools the upper floors and rarely runs long enough to dry a low level. A tune-up cleans the coil, clears the condensate line and checks duct insulation where ducts sweat. The rest is usually a dehumidifier set at or below 50 percent.
