"Tech said the fins were dirty causing it not to cool and cleaned fins, saw little dirt. I pointed out condenser fan was not running fast, he ignored. Found later that the fan was bad. They did nothing to fix the problem"

Energy Efficiency Auditing questions, answered by experts

You can increase your home’s load factor by replacing fuse boxes with a circuit breaker, hiring a licensed electrician to upgrade your electrical panel, upgrading wiring, or installing subpanels. An electrical inspection by an expert can help determine the state of your current electrical systems and how they can be improved.

Keep the unit full but not overloaded, ensure door seals are tight, set correct temperatures, and avoid frequent door openings. Position the appliance away from heat sources for optimal performance.

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.

Wood windows fall in the middle of the window frame materials when it comes to energy efficiency. They’re more insulating than aluminum and vinyl, but they aren’t as efficient as fiberglass or composite frames. If you love the look and lifespan of wood windows and want to maximize efficiency, you can upgrade to double-pane or triple-pane glass and consider window tinting and low-emissivity (low-E) coatings to minimize heat transfer.

A blower door test shouldn’t take more than an hour, and most can be completed in less than 30 minutes. Expect the test to take longer once you start searching for leaks with thermal imaging or want to include sealing such leaks in the time estimate. The test doesn’t take much time and can’t be rushed, but it will take longer in large homes or those with many air leaks.
