Ductwork

Increase the Efficiency and Lifespan of Your A/C Unit

High-efficiency A/C and heating systems perform heroically through Arizona’s extremes: summer heat, torrential rains, and dust storms. Poorly installed ductwork and insulation put an even heavier burden on cooling equipment. When hot air infiltrates your house faster than a struggling A/C system can transfer it outdoors, energy bills escalate and puts your system at risk for failure. Larson Air Conditioning provides ductwork, insulation, and sealing services for long lasting efficiency.

Expert Ductwork Services

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. Larson Air Conditioning technicians use the Air Conditioning Contractors of America Manual D method to determine ductwork layout and duct sizing. We 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 effective climate control and to assure system efficiency, quietness and performance.

 

Return Air Additions. When replacing a heating and cooling system, it is important to consider return air duct sizing. Many HVAC systems in Phoenix have undersized return-air ducts, that result in increased system stress, reduced airflow, reduced system capacity, reduced efficiency, and increased noise level from high air velocity.  Adding a return air duct reduces static pressure and allows the system to operate within its designed conditions.

 

Duct Leakage Testing. In a typical house, ENERGY STAR estimates 20 to 30 percent of cooled 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 and Grilles. 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.

Insulation Services

Insulation ratings matter. Your insulation’s R-value represents the material’s ability to resist heat flow—in or out. The higher the R-value, the better your blown-in or batt insulation performs. After inspecting your home and evaluating insulation levels and installation quality, Larson’s energy experts recommend services for improved home performance. These may include total insulation replacement, batt insulation realignment, air sealing or simply more blown-in attic insulation.

 

Air Sealing

Air sealing is a recommended service along with insulation. One key to having an efficient home is controlling air leakage. An inefficient home has high levels of uncontrolled air leakage. In Arizona, most air leakage occurs between the attic and the living spaces. Air sealing in combination with proper insulation improves the home’s ability to store conditioned air, which in turn improves home comfort and energy performance.
