Furnace & AC Maintenance in West St. Paul, MN
Maintenance in West St. Paul starts at $129 for a furnace or AC tune-up, or $219 for both. We clean, test combustion and safeties, measure airflow and refrigerant, and report plainly on what is wearing.
Tune-ups in West St. Paul homes
The big West St. Paul item is the chimney. Many 1950s houses vent the furnace and water heater into one masonry flue, and if the furnace has since been replaced with a PVC-vented 96% model, the water heater is left alone in a flue sized for two. At the fall visit we check the draft at the water heater, look for spilled exhaust at the draft hood and note signs of a damaged liner.
Spring is about airflow. Central air here usually arrived decades later as a coil on the furnace with ducts sized for heat, so iced coils and weak air to the far rooms are the common July problems. We clean the coil and measure airflow. Postwar houses have been remodeled often, and a finished basement or kitchen redo may have buried a return, which we look for. Landlords with several units can book unit by unit.

Tune-ups in West St. Paul: questions
My West St. Paul furnace was replaced but the water heater still uses the old chimney. Is that safe?
It can be a problem. A 96% furnace leaves the water heater alone in a flue built for two, and its cooler exhaust can condense, damage the mortar and spill at the draft hood. A draft test at the tune-up shows what is happening. The fix is usually a stainless liner or a power-vent water heater, quoted before any work.
I own rental properties in West St. Paul. Can I book tune-ups for several units?
Yes. Give us the addresses and access arrangements and we schedule around your tenants. Each unit gets its own written list of anything worn, so you can plan repairs across your properties instead of reacting to one no-heat call at a time.
