Seal Air Leaks and Maintain the Health of Your HVAC System

If you have any places where uncontrolled air is escaping or entering your home, you’re wasting energy and money. As a homeowner, you spend a great deal of effort making sure you have healthy and comfortable air inside your home. Air leaks, however, have the opposite effect. The good news is that you can seal air leaks quite easily once you know what to do.Seal Air Leaks and Maintain the Health of Your HVAC System

How to Check for Leaks

Checking for air leaks is simple to do on your own if you don’t have the budget to call in a professional. While you might not find them all, you can find most of your leaks by focusing on areas where they’re common. Start by checking these:

  • Doors

  • Windows

  • Piping or electrical wiring entrances

  • Fireplaces

  • Garage

  • Attic

Some homeowners just feel for leaks in likely spots with their hands on a cold day, while others walk the interior of the home’s outer envelope with a lighted incense stick, watching for places where the smoke wavers. You’re looking for any significant drafts coming from the garage or attic, along with other types of leaks.

Sealing Those Leaks

With half the job done, it’s time to seal air leaks. The two tools that you’ll likely need are caulking and weatherstripping. If the leak is on a stationary joint, use caulking, unless the gap is quite large. In that case, use spray foam. For leaks around doors or window sashes, weatherstripping is the way to go.

Insulation is also imperative for a properly weatherized home, though most types of insulation are intended to slow the transfer of heat energy rather than moving air. Any good energy-efficiency strategy for a home should combine finding and sealing air leaks with ensuring adequate insulation.
