Duct Leakage counts for more than 30% of the air loose in your HVAC system. The more air your system looses before it makes it into the home the harder the system will need to work and the more it will cost. With proper duct repair and insulation your system could become 30% more efficient making your rooms more comfortable while lowering your utility bills. Under the 2012 Energy Code in Maryland all new duct work needs to be tested in accordance to the 2012 IECC code. Contact Dr. Energy Saver to schedule your duct blaster testing.
