Insulation & Envelope Sealing

Insulation Services in Scottsdale & Greater Phoenix

In a typical summer, Phoenix-area temperatures routinely exceed 100 degrees, driving residents indoors to test their hardworking HVAC systems. Continuously running your AC at maxed-out capacity takes a toll on equipment and prolongs discomfort. One way to reduce the chance of early air conditioning failure is to adequately insulate your home with R-30 (or higher) attic insulation. To avoid baking attic temperatures and overworked HVAC systems, owners of older homes in Scottsdale, Phoenix, Tempe, Paradise Valley and surrounding communities can request a home energy audit and insulation evaluation from Larson’s certified ENERGY STAR® home performance contractors.

Insulation Increases HVAC Efficiency & Extends Unit Service 

High-efficiency HVAC systems perform heroically through Arizona’s extremes: summer heat, torrential rains and choking dust storms. Poorly insulated homes put an even heavier burden on cooling equipment. When hot air infiltrates your house faster than a struggling AC system can transfer it outdoors, energy bills escalate. And, when your system works harder than intended, it doesn’t keep you cool—and may break down too early.

As heat enters Phoenix-area attics, temperatures can exceed 150 degrees. This attic heat migrates downward, raising indoor temps and overworking cooling systems. High-quality Scottsdale and Phoenix attic insulation eases your home’s HVAC burden and slows pent-up heat from entering the conditioned space. Blown-in insulation and a tightly sealed building envelope serves as a thermal barrier that keeps your home comfy while reducing equipment stress.

Importance of R-Values & Insulation Levels

Insulation ratings matter. Your insulation’s R-value represents the material’s ability to resist heat flow—in or out. The higher the R-value, the better your blown-in or batt insulation performs. After inspecting your home and evaluating insulation levels and installation quality, Larson’s energy experts recommend services for improved home performance. These may include total insulation replacement, batt insulation realignment or blown-in attic insulation installation.

Larson came highly recommended and they lived up to every expectation. We had our AC go out on a Thursday evening and contacted our home warranty who could not send someone out until the weekend. With it being the middle of July you can imagine how quickly our home heated up. Luckily Larson squeezed us in last minute on a Friday evening & were able to come back out the next day on a Saturday to make our repair. Victor came out & provided cooling and was very prompt & detailed. He schooled us on our AC system because when we purchased the home 1 year ago we were told the AC was less than 5 years old turns out it was 2003 and had no warranty. With this information we decided to replace our AC. We thought about getting other quotes but after the speedy response from Larson we wanted to ensure we had that service for the years to come as well. Victor & Larson got our proposal to us no later than Monday and we were ready to install that following week. We were in no rush since we had temp cooling and knew others were without. The day came for our install and all the guys from Bruno to Sam & Lyle were AMAZING! Very polite, clean & did a great job! We have no worries when it comes to our AC, Insulation & Duct System for at least the next 10 years and know we made the best choice. Thank You Team Larson! =)read more

Clean, neat, prompt and highly knowledgeable service provider. I liked the text photo of the technician along with a call before his arrival. We signed up for their yearly service call so our a/c never breaks down more

I was initially disappointed with the post-installation support I received from Larson. They had done a fantastic job of helping me pick out a new AC unit and then installing it. However, the installation caused a very disruptive strobe light reflection to go through a significant portion of my home. Luckily, Jamie was relentless in helping me find a solution for this problem and I truly thank the Larson team for their creativity and dedication to helping me resolve my issue. Thank you!read more

First time using this company. Setting up the appointment was easy and everything was explained with knowledge and patience. Ryan came out and checked 3 rooftop units He was very professional and did not rush even though it was about 110 degrees today. He showed me pics and explained what he checked on each of the units. Based on the professionalism in the office and from Ryan I signed up for for an annual maintenance program with this company. I have had many different service companies here over the past 20 years and I am sure that we will be working with Larson for a long more

Very professional. He was respectful and explained what he was doing and what his diagnosis and plan was. Took time to cover his shoes with booties no matter how frequent and how short his trips were in and out of the house. He also showed pictures and explanation of the work involved. It was an overall great experience and would highly recommend him and the more

My initial call to set up service was handled in a friendly and professional manner. The were able to send a technician out the same day.Lyle was my technician, he called about 30 minutes prior to his arrival to let me.know he was on his way and about how long it would take him. I really appreciate this kind of service. I also like that the company texted me his picture. He was very professional and knowledgeable. He completed the work quickly. I was very happy with Lyle. This would be a 5 star review but I was disappointed that the $79 diagnostic fee is not waived or taken off the cost of service if you choose to have them make the repair. This was disclosed up front I was not surprised by this. The repair its self I believe was fairly priced but because I had to pay the diagnostic fee the repair turned out to be a little overpriced but they were the only company with good reviews I could get out today. They do wave the diagnostic fee if you have their service more

This review is long overdue, I've starting using Larson Air Conditioning back in Sep 2018 when another energy company messed up my insulation, attic seal, and duct repair, the first consultation was with Victor, and trust me, this man knows what he is doing. He pointed out the duct repair that was clearly messed up, insulation was smelly, and attic seal wasn't completely seal. After Larson Air Conditioning came out, they removed the smelly insulation, seal up the attic, repair all ducts, and added new fiberglass insulation, my house has felt so nice and cool during the summer heat.Every since then, I've continued to used them for my 24-point tune up on my AC and Victor continued to come out and perform the maintenance needed and pointed out things that may need replacement or how to improve my AC unit.Credits goes out to Victor, Sam, Axel, and Ryan, along with the owner, Jamie, they have been all great throughout the years since I started using them in September 2018, and believe me, I'll continue using them for all AC needs. They are worth every more

New client first time - Well it all started with Olivia. She is an Exceptional receptionist /customer service person that has superior phone skills. Olivia's excellent demeanor, knowledge and ability to understand landed me as a client . She assisted me with excellent service plan email options explaining the various choices I had to choose from for my AC/Heating systems. Olivia is a tremendous asset for Larson and this definitely reflects ones impressions that customer service is first and foremost at Larson AC.Technician Ryan arrived on time with his shoe covers on. l had previously received a text with his picture announcing his approximate arrival time. Ryan spent a sufficient amount of time with both systems inside and outside cleaning and servicing each unit. All the service work was explained thoroughly by Ryan. It was easy to decipher he has tremendous pride and excellent knowledge about the AC/heating units. Ryan also exemplified Larson's customer service philosophy.For me reputation, customer service, response time and excellent workmanship are first and foremost when I choose a new supplier.I am very satisfied with Larson. I recommend them more

The Larson team is amazing starting with Daniel who bid our AC replacement as well as the install team of Anthony, Victor, Eli and Sam. Doug is the project coordinator and he is very professional and thorough. Their pricing is very competitive and they pay attention to detail which is so important in installing air conditioning equipment. We highly recommend Larson Air Conditioningread more

Every technician has been top notch on both talent and trust, and Ryan's work today was just like that. And we just had Daniel give us an estimate for a new unit, as ours is very old, and it was an equally solid experience. The office has been very dependable and communicates so well. It just doesn't get any better, especially considering that this is an industry infamous for the opposite. Well done!read more

Andrew, Sam, & Eli we’re rock stars. These boys are the hardest working young men. The first day of doing our reduction & insulation they arrived on time and worked until we could have air conditioning. The boys went beyond the call of duty. They are kind, hard working & extremely conscious. We would hire Larsen again for our air conditioning needs without hesitation. Daniel did an awesome too...all of the keepers! Whatever they are getting paid it is not enough!!!Julia & Michael Lichtyread more

I highly recommend Larson Air Conditioning. They are very informative over the phone, they emailed me the information I asked for right away. Today when the technician Ryan came out to service our unit he was very professional and friendly. He took before and after photos of everything he did (which is great because I have no desire to get on the roof). He did recommend we have one more part cleaned/ not replaced just cleaned. He did show me pictures and I totally agree with him. The price is very reasonable ex specially since I know what just the part alone would cost us not including labor. I love that the first thing he said is i recommend having it cleaned/ Not you need to replace it or should replace it. Like most companies will do. Because of the great customer service we have received so far from Larson Air Conditioning and because of their technician Ryan This company will be servicing our A/C unit for a very long time. ❤️read more

Can’t say enough good things about Larson! Daniel and Victor were our lead technicians that replaced the unit on our house and both were very knowledgeable and communicative every step of the way. I never felt like I was being hustled into an upgrade that I didn’t need and they really listened to us and respected our modest budget. A+ service - highly recommend!read more

I highly recommend Larson Air Conditioning for your routine maintenance. I’m new to AZ, but it’s obvious that it’s critical to have your AC system maintained properly for a long life and to reduce the chance of issues on a hot day. I’m especially impressed with Ryan as he is completely thorough in his maintenance check. Upon completion he reviews everything and has taken detailed notes along with pictures to show you. Please send Ryan for my next six month maintenance more

Customer Service and responsiveness is excellent. The tech that came was exceedingly professional and a welcomed change from what I have been accustom to dealing with. I felt like it was a pretty honest exchange. However, the pricing does seem pretty high, but I don't have much of a frame of reference on the cost of A/C service and repair. I spent $700 to have one units capacitor replaced and both units have preventative maintenance which includes refrigerant and thorough cleaning of coils, housing, evaporator, and blower. Other than the cost i'm pretty happy with the service more

Moved into the area a year ago, and had some A/C repairs done by Ryan of Larson A/C, as well as a system maintenance inspection. Today, Ryan returned for our annual system check. Everything was up to par and no work was required. Ryan is very friendly, extremely knowledgeable, and arrives on time. Larson also offers maintenance plans that are efficient and cost friendly. I recommend them without reservation; good folks!!read more

What a great experience! We previously had 4 different companies come out to figure out the kinks in our a/c system with no success. Ryan came out to do our tune up and immediately knew what was going on and is preparing a plan to remedy it. He was pleasant, on time, and answered all my questions. SO glad I went with Larson A/C. Top notch!read more

If I can give 10 STARS, I definitely would! Hell of Company from Jeff, Doug, and the 3 installers that came today - Anthony, Victor, and Rick! These installers have such great working attitudes. They came in CLEAN and left DIRTY! The path they used indoor all covered including the closet, aisles, stairwells, and our clothes. They cleaned up afterwards and there’s just too much to say. Outside, both front yard and back yard, spotless.Jeff answered all my questions and provided all the information I need to pick Larson Air out of 7 that placed their bids.The company is just AWESOME from all aspects and even if you say it’s too early to make these claims because they just installed, well I’m sure they’ll back up their work.Thank You Guys! and to the owner - GOOD JOB! I have successfully referred you already even before you installed my units today. Rest assured that you’ll get lots of referrals from me!read more

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 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 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
