"Heatmizer (Bob Frechette) did an energy audit on our 1970 mobile home we were about to remodel. We followed his recommendations and had them spray foam and insulate after we gutted it. He installed a Mitsubishi Heat Pump that heats, cools and dehumidifies our cozy, home. The energy audit helped us attain an efficient, healthy home! We highly recommend using Heatmizer to make your home as efficient aand healthy as it can be."

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.
