"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

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

Home power is measured in kilowatt-hours, commonly expressed as kWh. The average home uses between 800 and 1,000 kWh per month. Peak usage (and highest bills) occurs in the middle of summer and the depths of winter. Keeping on top of your usage during these crucial months will lower your annual average usage considerably. 

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

Dehumidifiers typically use 300 to 700 watts of electricity per hour, whereas portable dehumidifiers use about 40 watts per hour. The exact amount of electricity your dehumidifier will generate depends on its capacity and energy efficiency. Generally, higher-capacity dehumidifiers generate more electricity than lower-capacity units, but they also usually have better energy efficiency over the long run.

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.
