Energy Efficiency Auditing FAQs, answered by experts

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.

There are several strategic ways to lower your home insurance premium. The primary one is to shop around and get quotes every few years to make sure you’re getting the best deal.

Finally, try to keep your credit score up; many homeowner insurance companies use credit scores to generate quotes.
