Ductwork

$79 HVAC Check-up

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 intake and return.

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 floors 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 duct seals
  • Incorrectly matched duct joints
  • 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Repair, seal or replace outdated ductwork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 ventilation 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 vent 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

Our indoor air quality specialists provide duct repair and sealing, duct replacement, new duct installation and duct insulation. Other expertise includes:

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.
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.
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.
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.
