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.

Courteous, professional and honest. Those are rare quality to find nowadays with service field people. Unlike today, most ac & heating people were trained to sell products for commission incentives, that help promote corruption and corrode honesty.read more

This is the best company I've ever worked with for any service at my home. My air went out on a day the high was over 120. I called and told Jamie that I didn't know if I needs a new system or a repair. She sent Jason who was awesome. He knows the repair and installation side of things. He brought parts and a temporary unit to cool the house until they could get back to do the install of the new system. Jason and Victor have been out several times to make sure everything was perfect throughout the house. A drywall company was lined up as well to fix the attic entrance. Larson Air was always a step ahead. Jamie and Jason were efficient and coordinated things the way they'd want it done at their own homes. Because of the stellar reviews online I waited to call Larson Air during their hours vs calling an emergency company during the night. I'm glad I did! I didn't comparison shop, I feel like their pricing is average, but the service can't be beat. I'll pay for service every time. Thank you all so much! I've passed your info along to my realtor friends and neighbors in the area.UPDATE:A year and a half later, still AMAZING! I called because I have been so cold downstairs at home. They scheduled someone to come out the same day. He was running early and I was not home yet. I spoke with Jamie several times that day and she was so accommodating with her schedule. She told me not to worry and to just give her a call when I was on my way home, because I was running late by that point. They're great and it was an easy fix.read more

I couldn't be happier I chose Larson Air. Everyone I came in contact with was friendly and courteous. It is very apparent the owners and employees care about their customers and providing excellent service while also remaining reasonably priced and straight forward. The process of replacing my unit was very smooth there were no issues and they were somehow very quiet while doing so, it was not as nearly as loud as I expected. They finished quicker then quoted and they triple check their work making sure everything is working perfectly that day as well as coming back a few days later. I couldn't be more pleased. Great company, great service!read more

After being jacked around by 3 other of the larger competitors in the valley, I called Larson Air. Despite taking my frustrations out on the young lady who answered my call, every one of the team members I interacted with were very professional, knowledgeable, PROMPT!, and thorough in their explanations. Their prices are very fair and quality of work was very good. They even text a picture of the tech who will be showing up so you know who's supposed to be there! Love these folks, highly recommend, and will most definitely use them again and again!!read more
