Ductwork

Duct Repair & Replacement in Greater Phoenix & Scottsdale

Air ducts are a vital part of any HVAC system. Correctly sized and sealed ductwork facilitates the smooth, quiet flow of indoor air, delivering cool comfort to every room. Suitably sized return ducts also maximize AC efficiency by promoting balanced air return and supply.

In older homes built before current energy standards, ducts are a common cause of poor AC performance and rising utility bills. Aging or deteriorating air ducts hidden in ceilings, walls and attics go unnoticed when new cooling equipment is installed. This neglect leads to common air duct problems like these:

  • Crushed, sagging or kinked ducts
  • Disconnected ducts
  • Leaky ducts
  • Incorrectly designed and installed ducts
  • Stamped registers & grilles
  • Undersized return ducts
  • Under-insulated ducts

Repair, Seal or Replace Outdated Ductwork

Larson’s duct replacement solves problems that stem from incorrect configuration, poor workmanship and old duct systems. Air duct design and arrangement is sophisticated and requires the expertise of specially trained technicians. Our NATE-certified team calculates your home’s recommended duct size and register placement to assure high-efficiency heating and cooling. Replacing an old HVAC unit without updating ductwork leads to poor equipment performance, much like attaching a frayed extension cord to a new lamp!

At Larson, we know ductwork design directly influences HVAC performance and other installation factors like these:

  • Equipment sizing
  • Unit efficiency
  • Equipment malfunctions
  • Envelope infiltration
  • Operating costs
  • Indoor air quality
  • Noise levels
  • Occupant comfort
  • Owner satisfaction with the system

Duct Services by Larson

To ensure year-round comfort during cooling and heating seasons, our Phoenix-area indoor air quality specialists provide duct repair and sealing, duct replacement, new duct installation and duct insulation. Other expertise includes:

  • Duct design & Manual D calculation. The Air Conditioning Contractors of America Manual D is the method used to determine ductwork layout and duct sizing. Larson’s NATE-certified specialists use this gold standard for designing and sizing ducts for new and retrofitted HVAC systems. Manual D calculations are used in conjunction with other HVAC installation standards to deliver homeowner satisfaction and assure system efficiency, quietness and performance.
  • Return air additions. When replacing HVAC systems and ductwork, it is often wise to incorporate additional return air vents. Most HVAC systems have undersized return-air ducts, resulting in noisy and less-effective cooling. Adding a return air vent reduces static pressure and prevents air from becoming “bottlenecked” in your vents.
  • Duct leakage testing. It’s no fun to pay for wasted AC. In a typical house, ENERGY STAR estimates 20 to 30 percent of conditioned air is lost through duct cracks, leaks or poorly sealed joints. Larson technicians will test existing ducts for leaks and recommend duct repair, duct sealing or duct replacement when necessary.
  • Installation of high-flow registers. High-flow return grilles are designed to be more aerodynamic than previous models, reducing static pressure and enabling more air to flow through. This means increased comfort, reduced energy use and less chance of noise.

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
