You might wonder why you should invest in annual furnace maintenance. In short, spending a little now can help you save a lot later on. Here’s how:

  • Lower heating bills: When your furnace is clean, lubricated, and tuned up, it operates more efficiently. This, in turn, lowers your utility costs all winter long.
  • Fewer repair bills: Emergency furnace repair is not only inconvenient—it can also get expensive. Reduce the chance of a midseason breakdown and the associated repair costs by maintaining your furnace before winter starts.
  • Longer equipment life span: You will eventually need to replace your furnace, but why not prolong the life of your existing heating system? Routine tune-ups keep your furnace from experiencing excessive wear and tear. This simple preventative measure is the key to avoiding premature furnace failure—and the replacement costs that go with it.
  • Warranty preservation: Most HVAC manufacturers require proof of annual professional maintenance. Without this, you might void your coverage, meaning that any claims you make under your HVAC warranty could be denied. Preserve your warranty with a routine tune-up every fall.
  • Boost in-home comfort: The benefits of furnace maintenance aren’t just monetary. After all, you can’t put a price on home comfort! Still, you can expect to enjoy excellent airflow, even temperatures from room to room, and better indoor air quality by keeping up with recommended yearly maintenance.
