Indoor Air Quality

Greater Phoenix Indoor Air Quality (IAQ) Services

Most homeowners worry more about outdoor pollution than airborne contaminants inside their homes, but since Americans spend around 90 percent of our time indoors, building air quality is critical to health. According to the EPA, some indoor pollutant levels are two to five times higher than those outdoors. Homes built to be airtight for energy efficiency are at an even higher risk for poor air quality.

At Larson, we care as much about your air quality as we do your comfort. The air circulating in your home contains allergens, molds, chemicals, bacteria, dust mites and other contaminants. Over time, these pollutants may cause sinus inflammation, aggravated asthma symptoms, headaches and more. To help you breathe easy, we install and service air purifiers, home ventilation systems and air filtration systems from industry-leading manufacturers.

Indoor Air Quality Expertise

You may need air quality equipment if you notice symptoms like these while spending time indoors:

Respiratory problems
Asthma & allergy symptoms
Headaches or migraines
Flu-like symptoms
Nausea

Larson is proud to provide Scottsdale & Phoenix customers with the following IAQ products and services:

Air Purification & Air Filtration

Whole-house IAQ equipment works with your home’s HVAC system to filter and destroy contaminants before they make their way into the air you breathe. Air filtration systems use media and electronic filters to capture pollutants. Air purifiers target and remove smaller particles that escape the filter.

During your home performance checkup, Larson’s air quality specialists will evaluate indoor air quality and ventilation systems. In some cases, we may recommend air purifiers or air filtration systems to protect your health and enhance indoor comfort.

Carbon Monoxide Detection

Called a “silent killer,” carbon monoxide is sneaky. It’s an odorless, colorless gas that may not be detected until someone in your home is sick. Newer, high-efficiency sealed homes are at higher risk for CO buildup because the tight joints trap gases and pollutants inside. Larson provides carbon monoxide testing that lowers your family’s risk of CO exposure.

Heat & Energy Recovery Ventilators

Airtight, energy-efficient homes keep contaminants from escaping and lack the ventilation required for optimal air quality. Larson’s air quality professionals install and service heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs) that improve indoor ventilation. HRV systems transfer heat from stale exhaust air to incoming fresh air to enhance winter comfort and air quality. ERV systems are ideal for warmer climates since they transfer heat and humidity from incoming air to outgoing air.

Larson-installed ventilator benefits include:

Minimized energy waste
Elimination of stale, stuffy or contaminated air
Fresher air without production of ozone
Balanced ambient humidity levels (40 to 60 percent)

Exhaust Fans

Similar to energy recovery ventilators, exhaust fans help your home rid itself of humidity, contaminants and odors from bathrooms, laundry rooms or closets—as it if it were exhaling. Ventilation and exhaust fans also control mold and mildew, protect wallpaper and paint and maintain wood by quickly moving moist air (like shower steam) outdoors.

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 time.read 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 company.read 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 contract.read 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 penny.read 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 highly.read 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 checkup.read 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 provided.read 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 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
