Checking for Leaks in Your HVAC System

Do you have a traditional ducted HVAC system? Energy loss through the ducts alone could be 30% or more! If you have the time and energy to do so, finding the leaks in your ducts is worth it. On average, fixing the leaks in ducted system costs about $350, but the savings are higher in the first year after repair.

Equipment Leaks

If there is a leak in the air handler itself, it should be able to be seen, heard and felt. Poorly fitting cover panels missing screws and where the air filters are inserted are common places for air leaks to occur. Every panel on the unit should be secured with a screw and not bent. Leaks in this area can be sealed with tape mastic or permagum.

Leaks Due to Duct Damage

When ducts are located in storage areas like attics, it’s easy for them to experience damage as a result. Depending on the severity of the damage, these leaks could be a minor issue or a colossal waste of energy. Metal ducts that are not correctly mounted with screws and duct zip ties are prone to falling apart. Fiberglass ducts commonly experience crushing and puncturing. Flex ducts have an outer covering that can tear and cause moisture accumulation on the inside of the ducts, leading to even bigger problems.

Air Return Leaks

One of the most difficult HVAC system leaks to detect is in the air returns. Negative pressure is difficult to see or hear, so finding these leaks requires a detailed inspection of the ductwork. Non-ducted returns are common sources of air leaks and indoor air pollutants, so it is best to have them refitted with a metal or plastic lining. Seams should be tight and covered with mastic.

Ask a Professional

Finally, you should work with a professional HVAC technician to have your system evaluated for leaks. A professional will know what to look for and have specialized equipment to make the necessary repairs.
