An Osseo tune-up is $129 for one furnace or air conditioner and $219 for both, with CO readings in postwar homes with shared chimneys. We clean, test the safeties, take combustion and CO readings, measure refrigerant and airflow, and report what is wearing.
Osseo's postwar houses have usually been through several furnaces, so a tune-up begins at the chimney, where the furnace and water heater often share one masonry flue. We run both appliances, watch the exhaust at the draft hood, look for rust at the flue-pipe joint and scorching on the water heater, and take a CO reading.
The air conditioning here is mostly a retrofit, with a coil set on a furnace that was never planned for one and returns sized for heating. When that kind of system runs all afternoon, the return side is often the limit, so we measure the coil's temperature drop and airflow, not just the condenser. For landlords, duplexes and townhomes with side-by-side condensers, we clean the coils and check spacing so units are not breathing each other's discharge. Since rentals are licensed and inspected by the city, a documented furnace check helps.

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.
Yes, and it is a sensible time. We clean the furnace, test the safeties, check the draft and flue, and take a CO reading, then give you a written list of anything wearing. Ask us whether the visit fits what the city's rental inspection looks at. A duplex is priced per furnace.
Draft and condition of the flue. We run both appliances, watch the exhaust at the draft hood and look for rust flakes, scorching or spillage, and take a CO reading. A failing flue or a water heater left alone in an oversized chimney after a furnace swap can spill exhaust. If it does, we quote a liner or new venting.
