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Repair, Seal or Replace Outdated Ductwork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.

Lyle was awesome and very informative. One thing however was when they called to make my maintenance appointment they... quoted me one price. Larson installed both of my units and they should have that on record. Lyle was surprised to learn that I had 2. The price quoted was only for one. So it was double the cost I was expecting. They should have quoted me at both of them so I knew what to expect. I was a bit blindsided and that affected my budgetread more

Our heating went out. The next day I was able to get a crew out to check the system. Since the compressor was shot and... it would cost nearly $3,000 to repair a 15 year old system I opted to buy a new one. I met with the rep the next day who went over all the options. The day after that the crew arrived and replaced the old unit. They were friendly, thorough & efficient. So after only two days I have a new system. No complaints.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.10 Dec 2019 - recently had Sam do some work to bring both of my furnaces up to code. He is extremely knowledgeable and explain what he was doing as well as some things to keep any eye out for in the future. Thanks for great work Sam!read more

Sam was the technician sent for my service call and I really appreciate that he called prior to his arrival to let me... know he was on his way. He arrived on time and immediately set about his work. He covered his shoes with booties prior to entering my home, which I truly appreciated. Sam was professional, courteous, and personable; I hope I can request him for my next service call. i will definitely be recommending Larson to those I know who may be in need of the services offered. I have already recommended the company this morning to someone I know.read more
