AC Replacement & Installation

Air Conditioning Installation & Replacement

The health, comfort and productivity of Scottsdale and Phoenix homeowners ride on the performance and efficiency of their air conditioner installations. If your aging cooling system can’t keep up with the Arizona heat or it’s nickel-and-diming you at every turn, it’s probably time for AC replacement.

Shopping for an AC system can be confusing and frustrating, and choosing a system size, efficiency rating, manufacturer and model can overwhelm even the most determined researcher. When you partner with Larson Air Conditioning, our team presents all your options and helps you select the HVAC unit that’s best for your comfort and budget needs. 

The Larson AC Installation Difference

Larson Air Conditioning hires experienced, NATE-certified technicians to complete your air conditioning installation, AC maintenance, or AC repair. Our commitment to homeowners begins with education, communication and understanding. Since our team members are technicians—not salespeople—you won’t get the hard sell. Instead, we take time to teach you about your system and help you decide if replacement is best, considering things like equipment age, efficiency and reliability. (Hint: If you’ve spent a fortune fixing your system or it is over 15 years old, a new air conditioner may be the wise choice.)

After recommending repair or replacement of your home AC unit, our highly trained technicians provide a flat-rate estimate that doesn’t leave you guessing. Arriving promptly and respecting your home, flooring and furnishings, we strive to create the ideal service experience. Most importantly, we promise your Phoenix or Scottsdale AC installation will be done right the first time. We don’t take shortcuts—and we never use substandard materials. Installing your air conditioner according to the manufacturer’s exact specifications, we guarantee our work and assure your new system operates at peak efficiency for years to come.

Installation Guidelines for Best AC Performance

Replacing an aging heating and cooling system with a new, high-efficiency model is a great start—but its performance is dependent on proper installation. According to ENERGY STAR®, improper installation can lower efficiency up to 30 percent while increasing utility bills and potentially shortening equipment life. Larson Air Conditioning takes pride in our work, so we guarantee best-quality AC installation. Quality guidelines include:

  • Proper equipment sizing. Selecting proper HVAC equipment size is essential to performance, comfort and energy savings. A system that is too large will cycle on and off frequently, and a system that is too small won’t keep up with the heat. Incorrect sizing puts undue stress on air conditioning components, shortening their lifespan.  
  • Duct sealing. Leaky ducts compromise comfort and drastically decrease cooling efficiency. Larson technicians evaluate your duct system, identify leaks and seal ducts with mastic tape or an aerosol sealant. We also install new ducts and replace aging ducts as needed, since a high-quality duct system is essential to home climate success.
  • Proper refrigerant charge. Incorrect refrigerant levels lower the efficiency of your air conditioning system by five to 20 percent and may even cause costly component failure. We ensure refrigerant levels are optimal for the system you choose.
  • Airflow optimization. High or low airflow leads to discomfort and escalating energy bills. Larson Air Conditioning installation includes thorough airflow testing and adjustment.

We just had a new unit installed. The entire team was great to work with from the time we got the quote to the installation. The techs, Anthony and Lyle, were prompt, very thorough and did a great job explaining everything. It's only been a few days but we are extremely happy with the quality of the unit and experience with Larson.read more

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
