Furnace maintenance

A fall tune-up keeps your furnace safe and efficient, and makes a mid-winter breakdown far less likely.

What a tune-up covers

A precision tune-up, a professional cleaning, and a safety check. We inspect, clean and adjust the system and replace any worn parts.

Best time to schedule

Early fall, before the first cold snap. Krinkie’s Club members get this visit every year.

Why it matters

  • Safer operation, checked by a professional
  • Lower heating bills
  • Fewer winter breakdowns
  • A longer system life

Common questions

How often should my furnace be serviced?

ENERGY STAR recommends an annual pre-season check-up and says heating systems should be checked in the fall. In Minnesota, that means before the long heating season starts.

How often should I change my furnace filter?

ENERGY STAR recommends inspecting your filter monthly and cleaning or replacing it as needed. Check it more often during heavy use in winter or if you have pets.

What does the Krinkie's Club maintenance plan include?

Krinkie's Club includes two tune-ups each year, an air conditioning tune-up in spring and a furnace tune-up in fall, plus 20% off repairs, a reduced diagnostic fee and priority service.
