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.

Lyle from Larson Air was awesome! Great service and expertise. I never leave reviews but he was so professional and... good at his job I just had to! He was so clear, understanding, honest and thorough. He was always on time and finished up so quickly. He never left a mess. The A/C in our over 4,200 sq ft house is working so much better now! He sealed some leaks that he discovered when he came out the first time and he added freon. Also, the master bathroom Has never felt cool since we moved in. We are the original owners and have lived in this house for about 10 years. Even the builder had no solutions when we mentioned it during a walk through 10 years ago. Lyle had a great idea to add an A/C duct to the master bathroom with a direct shot from the a/c unit to the master bath. It was such a great solution and that room finally feels like it’s getting A/C! I think we will be seeing a huge savings on our electric bill too because we won’t have to crank down the air anymore to feel like it’s working. Great job Lyle! Highly recommend Larson! Ask for Lyle! You won’t be disappointed!!!read more

Not satisfied with a prior air conditioning repair company I searched online for a new one. I contacted Larson air... conditioning because of the great reviews on Google and Yelp and also because we like to support family run companies. I was not disappointed. Lyle came out yesterday since I was concerned about my mother’s air conditioner. He could have made up any problem and I would not have been any the wiser but instead, after a thorough review let me know the system had no problems. He took the time to explain why it was operating the way it was, using language I understood (and showing me as well). He was professional, courteous, and had appropriate Covid 19 protection on to keep my mother (and me) safe. He wore booties inside at all times to keep house clean, and in general made me feel we were in good hands. He offered suggestions for improvement but used no hard sell tactics whatsoever. Larson (and Lyle if possible) will definitely be both my mom’s and our go to company from now on. Thanks!read more

After a big storm hit our area last evening, one of our AC units went out. Larson Air was available the same day we... called, Leo (our service tech), was on time, considerate and communicated with us throughout the entire time he was here. Our AC is fixed and we couldn’t be happier! Definitely would recommend Larson to anyone.read more

Called Larsen on a Saturday. They arrived and got the A/C working within 4 hours of the initial call. Bad fuses. They... did not price gouge us for after-hours service. They provided several photos of read outs of diagnostics. I like these people! They are fair and square. Old school.read more
