The new building code which is applicable to all homes permitted after March 1st requires duct leakage testing of all new duct systems. This includes new duct systems for existing homes. We are receiving a number of calls from HVAC contractors requesting duct leakage testing. This is a test that we are experience in as we perform duct leakage testing on all of the ENERGY STAR homes and on many of the existing homes that we inspect. Give us a call today to schedule a test for your next job.
