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Repair, Seal or Replace Outdated Ductwork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.

My husband and I had shopped around for a business who could fix our air flow issues in our house. Larson Air Conditioning responded immediately and had someone out the next day for a quote. The quote was very reasonable and they were sure we understood our options. We decided to book our service and they were out the next day with two teams to get the job done. They were timely and efficient, they completed what normally sounded like a two day job in just over three hours. Bruno was sure to walk us through each step and answer any questions we had. Bruno, Sam, JC, and Caleb were awesome! We highly recommend this company.read more

I have used Larson twice now since I have two HVAC units to cover my home. They are professional, ethical, reasonably priced, and punctual. They send you reminders via email and text which I find helpful. They even send a picture of the technician who sill be showing up at your door so there are no surprises. All of their technicians (Victor, Lyle, etc.) do an excellent job. They go over pricing before they start the job so you know exactly what you are paying for. They even send you a handwritten thank you note in the mail! Who does that anymore? I highly recommend Larson.read more
