Leaking Air and Losing Money?

Is your home leaking air, and are you losing money in the process? You’re not the only one. This is a common problem. In fact, the Department of Energy estimates that the average homeowner can save 10% by focusing on the airtightness of their building.


KW Lang Mechanical has been serving homeowners in Solon, Ohio, with HVAC services since 1927. Our company cannot stress enough how important it is to have your ducts cleaned and inspected every several years or so. Joint seals will wear out over time and allow conditioned air to escape. Such leakage can be particularly problematic and expensive if the air is leaking into the attic.

Natural Ventilation

A hallmark of modern home construction is that they are sealed well. This is not the case with older homes, including those just built 10 years ago or so. A home that is not sealed well can leak air through walls and even the foundation.

Windows and Doors

Doors and windows are other common areas where air leaks can occur. Sometimes, the fix can be as simple as new weather-stripping, fresh caulk and a door sock or three. In more serious cases, it may be necessary to upgrade to energy-efficient windows and doors.


Insulation breaks down over time. Insulation in your attic is particularly important because the attic temperature should be closer to the outdoor temperature. Insulation in walls and crawlspaces that have begun to break down can cause loss of air as well.


Fireplaces can leak a lot of air, and the professional recommendation is to have your fireplace inspected annually. You can skip cleaning it yearly if you don’t use the fireplace that much, but the inspection for air leakage should never be skipped.
