"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."

They are not cheap but they do a very good job. Everyone is very professional and very educated. They always show up on time."

Energy Efficiency Auditing FAQs, answered by experts

Yes, advising on models that save electricity and reduce utility bills.

Yes, barndominiums are energy-efficient as long as insulation professionals properly install quality insulation, windows, and doors. Utility bills for barndo living can be up to 50% lower than those for a traditional home.  Make your barndo more energy efficient by working with contractors and HVAC professionals to strategically place windows, doors, and heating/cooling systems. 

Yes, skylights can affect a home’s energy efficiency, either positively or negatively. Properly installed, energy-efficient skylights with Low-E coatings, double glazing, and UV-blocking glass can help regulate indoor temperatures and reduce heating and cooling costs. However, poorly insulated or older skylights can contribute to heat loss in winter and excess heat gain in summer, lowering overall energy efficiency.

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. 

A home energy audit costs about $420 on average, with prices ranging from $100 to $2,250 or more. The final cost depends on factors like your home's size, location, the thoroughness of the audit, and the specific tests performed. A basic Level 1 walk-through inspection typically costs between $150 and $200, while a comprehensive Level 3 audit with detailed testing and a report costs around $900. Homeowners may be able to use the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit to cover up to $150 of the audit cost.

Costs for common individual tests include:

  • Blower door test: $350

  • Duct testing: $100

  • HERS test: $375

  • HERS certification: $200

  • Infrared imaging: $200
