"The company was paid to diagnose and fix a leak to my roof. They determined that a small patch of roof needed to be replaced. A couple of weeks later the leak continued from the same spot in the ceiling. The tech again came out and claimed it was another leak in a different spot although the leak inside was in the exact same spot. They did not fix the problem the first time and wanted more money for this “new leak.”"

Energy Efficiency Auditing questions, answered by experts

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

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.

Leaving lights on raises the electric bill, but not as much as having high-wattage light bulbs. The best way to save on electric costs is to swap your light bulbs to LED or CFL bulbs that use far fewer watts. You can also use smart lights and light switches to control usage via a smartphone or voice-controlled device.

Smart home upgrades can be worth the money. Several upgrades, including smart thermostats and ceiling fans, can help reduce your energy bills. Others make life more convenient, freeing up your time to do what you love (or get more work done). And some smart home upgrades, such as entertainment systems, simply make life more enjoyable. All are worthy causes.

R-value is a measurement that dictates how much resistance an insulation material has against heat flow—or how well it can stop heat from coming and going. A higher R-value, which is attributed to thicker and more dense materials, means the better the insulation performs. There is not one universal recommended value. It depends on climate zones. For example, Alaska, which has a naturally cold and arctic climate, has higher R-value recommendations than the hot and humid Hawaii.
