HVAC Rater Service

We seal off all the supply and return registers and connect a fan pressurization device to pressurize the duct system to record the amount of leakage. With this information and calculating the airflow of your system, we can determine the percentage of duct loss in the duct system. Without proper duct sealing, the average duct leakage in California is 30%! Proper sealing is cost-effective and provides more heating and cooling into the building providing an energy savings, improved comfort and improved indoor air quality.
