AC Maintenance

Air Conditioner Maintenance in Scottsdale & Greater Phoenix

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.

My husband and I had shopped around for a business who could fix our air flow issues in our house. Larson Air Conditioning responded immediately and had someone out the next day for a quote. The quote was very reasonable and they were sure we understood our options. We decided to book our service and they were out the next day with two teams to get the job done. They were timely and efficient, they completed what normally sounded like a two day job in just over three hours. Bruno was sure to walk us through each step and answer any questions we had. Bruno, Sam, JC, and Caleb were awesome! We highly recommend this company.read more

I have used Larson twice now since I have two HVAC units to cover my home. They are professional, ethical, reasonably priced, and punctual. They send you reminders via email and text which I find helpful. They even send a picture of the technician who sill be showing up at your door so there are no surprises. All of their technicians (Victor, Lyle, etc.) do an excellent job. They go over pricing before they start the job so you know exactly what you are paying for. They even send you a handwritten thank you note in the mail! Who does that anymore? I highly recommend Larson.read more
