"Solari energy is great. They guided me through financing, and I was able to pay nothing down. I spoke with my tax representative, and I qualified for the federal renewable tax credit as well. They put in a 12 kW system with a 9 kW battery backup at my house. They made the whole process easy. The installation team was fantastic and friendly. Any questions I had, Solari got back to me that day."

"Went very smoothly. Everyone I was in contact with was professional. Reasonably priced. The service tech was also very respectful of me being immunocompromised regarding COVID-19, which I greatly appreciated. I plan to use them when it comes time for a tune-up."

"Our Home Warranty Company (Old Republic) sent Onesource to our home to fix an AC problem.   They were the 2nd company sent out, the first one charged me a 60 dollar service call fee and left in 10 minutes after saying he cleaned some dust out of the fly wheel.   Turned out, when Onesource came out our A-coil was frozen over and that is what was causing the vibration noise, not the "dusty" fly wheel.       Since we had paid the service call fee just a few days before, Old Republic paid for the Onesource call.   They're due to return in the spring to add R-22 to the unit because they found it was only low in pressure.    We'll let you know how that visit goes."

"After installation there were various problems that required my propane provider to become involved. Comfort solutions took care of all of the coordination as both companies worked to locate and resolve the problems. All said it took 2 days. By the 2nd day the service manager was on-site with the technician. The attention and responsiveness were excellent. That really went a long way to easing what could have been an extremely frustrating experience. Excellent customer service."

Energy Efficiency Auditing FAQs, answered by experts

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.

Electric fireplaces use an average of $1.85 of electricity every eight hours. These minimal operational costs aren’t likely to make a big difference in your electric bill—unless you’re using it as a primary heating source for your home and it’s running most of the time.

There is no blanket figure for a residential home’s electrical load, since load varies by the size of the home, how many appliances are used, and the efficiency of their electrical systems. Typically, however, it’s safe to assume 40 to 60 amps is the average electrical load of a residential home. 

Yes, with features like LED lighting and variable speed controls for efficiency.

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.
