There are a variety of factors that impact a heating and cooling system's efficiency, including the size and age of the equipment. Your home's insulation also affects how well the device runs. When a structure isn't properly insulated, you may require more frequent HVAC repairs. If you’re facing issues with your system, here are a few steps to take to decide whether your insulation may be to blame.

3 Ways to Tell If Your Home Is Under-Insulated

1. Measure Insulation Levels

While you don't have easy access to the inside of your walls, insulation is visible in the attic. Recommended insulation varies by the type of material used, but on average, you want 10 to 14 inches of coverage. You can measure this using a ruler or simply eyeball it.

If the material is covering the floor joists, it shouldn't be a problem. However, if it's filled up to the joist or lower, then you may need to add more. 

2. Check Your Utility Bills

When a home is poorly insulated, the heating and cooling system is constantly battling to maintain a comfortable interior temperature. In this case, the equipment has to work harder than normal, often kicking on more frequently and running for longer periods.

3. Evaluate Your Comfort Level

One of the simplest ways to identify an insulation problem is checking for drafts. This is easy to do in the winter because rushes of cold air are more noticeable. Drafts are common when windows and exterior doors aren't properly insulated. If you find a gap letting in a draft, weatherstripping or caulking should help.
