Ongoing Service
Why annual Air Conditioner maintenance is worth it
Fewer breakdowns
Most July failures start as small issues a May tune-up catches.
Lower energy bills
A clean, properly charged system uses less electricity.
Longer system life
Maintained ACs routinely last 15+ years. Neglected ones don't.
Warranty protection
Most manufacturers require annual service to keep coverage valid.
When to schedule Air Conditioner maintenance
Spring is ideal — get your tune-up done before the first heat wave, when your system is about to work its hardest and our schedule (and everyone else's) fills up fast. That said, a late tune-up beats no tune-up. If your AC hasn't been looked at in over a year, now is the right time, whatever the calendar says.

FAQ
Common Air Conditioner Maintenance Questions
How often should my air conditioner be serviced?
Once a year, ideally in spring. If you also have a furnace, pairing a fall heating tune-up with a spring cooling tune-up keeps the whole system covered.
How long does a tune-up take?
Plan on about an hour, sometimes a bit more for older systems or if we find something that needs attention.
Is maintenance really necessary if my AC seems fine?
"Seems fine" is how most breakdowns start. The problems that kill air conditioners — dirty coils, low refrigerant, weakening electrical components — don't show symptoms until they've already done damage.
Do you offer a maintenance plan?
Comfort Club membership covers your annual AC and furnace visits, plus 10% off repairs, priority scheduling, and more, for $189/year. Ask about it on any visit, or join anytime.
