Periodically replacing your air filter will significantly improve your heating and cooling system’s performance. When the filter is dirty, the fan uses more energy to force the air through. When the filter gets too clogged, the whole system can shut down –triggering the need for professional services that could cost hundreds or even thousands of dollars.
The outer walls, ceiling, windows, doors and floor make up the “thermal envelope” of your house. Any gaps or holes in this envelope allow the conditioned or heated air inside your house to escape. When you add up all the small gaps, holes, cracks, and leaks, it’s often the equivalent of leaving a couple of windows wide open– all the time.
