Furnace & AC Tune-Ups in Woodbury, MN
Book a Woodbury furnace or AC tune-up with us for $129, or both on one visit for $219. Many homes here still run builder equipment from the same era, so we test the parts that tend to fail at that age. Ask us about a maintenance plan for scheduled visits.
Tune-ups calls in Woodbury homes
Houses in a Woodbury subdivision tend to have the same builder furnace and condenser, installed the same season, and they age together. A tune-up here catches the parts that fail in that stretch of life: flame sensors coated enough to cause lockouts, hot-surface igniters near the end, inducer motors getting loud, and on the AC side, run capacitors that have lost capacity and contactors with pitted points. We test each one rather than just looking at it.
Two items are particular to Woodbury's newer homes. Many have an air exchanger, and its filters and core need cleaning and its airflow balanced, or it runs without doing much; we can check it on the same visit. Many also have a high-efficiency furnace with PVC venting and a condensate line running to a floor drain or pump in a finished basement, where a clog or a failed pump can soak carpet before anyone notices.

Tune-ups in Woodbury: questions
Can you service the air exchanger in our Woodbury home at the furnace tune-up?
Yes. We clean or replace the filters, wash the core if it's removable, clear the condensate drain and check that the fresh-air and exhaust hoods outside aren't blocked with lint, leaves or snow. Balancing the two airflows is part of it, since an unbalanced unit can depressurize the house. We confirm the price for adding the exchanger when you book; maintenance visits run $129–$349.
Furnaces on our Woodbury street are failing. Can a tune-up tell us how long ours will last?
Not to the month, but it tells you a lot. We check the heat exchanger for cracks and rust, the inducer for bearing noise, and the igniter and flame sensor, then tell you which parts are wearing and what replacing them would cost. If the furnace is close to the end, you get time to plan a replacement in fall instead of taking whatever's in stock during a January cold snap.
