AC Maintenance

Air Conditioner Maintenance in Scottsdale, AZ

Imagine driving your car for several years without a tune-up or oil change. If this sounds absurd, consider that the average air conditioning and heating system runs about 3,300 hours per year. (That’s like driving 214,500 miles at 65 miles per hour!) When your Phoenix-area air conditioner is neglected, it costs more to run, won’t perform as well—and requires earlier replacement. The best way to prolong the useful, efficient life of your home comfort system is to schedule routine air conditioner maintenance and safety inspections.

What Happens During a Phoenix AC Tune-Up?

The monsoon season, haboobs and dust storms in the Phoenix-Scottsdale area cause AC systems to deteriorate much faster than other parts of the U.S.

The goal of Larson’s precision HVAC tune-up is to pinpoint problems and restore your air conditioner to maximum operating standards. Regular HVAC care also reduces the chance of a catastrophic breakdown, since we find small issues before they become an emergency. Members of Larson’s Cool Club air conditioning maintenance program also benefit from VIP discounts on repairs and new equipment!  See our pricing here.

Upon arriving at your home, our technicians use a time-tested, exhaustive 24-point cooling checklist.
