"At every step along the way they were thorough and professional. The estimator provided a very detailed scope and quote and patiently answered my questions. The installation crew was quick, efficient, friendly, and were so meticulous with their prep that up you couldn't even tell they were here after they left. I also appreciated the "after-photos" they sent me, it looks great!"

"We had a wonderful experience having our new units installed by Sunset Air. Our initial contact Jessie was great to work with. The installation team of Ian, Jason, and Michael, and the Electricians Tristan and Justin were all very professional and did a great job. Jessie made several trips to our home, confirming our system as the team at Sunset Air put together a plan and identified what system would best suit our needs. The team was able to troubleshoot our old 1970 furnace and heat pump system. The system was a unique installation in an outside furnace room with a lot of the plumbing running under the home. Removal was quick. The new installation required some custom-designed Ductwork and some changes to the electrical system to ensure proper installation. The installation team was always on time, and when they left, you would never have known they were there; they took everything with them daily. Once the system was complete, we received a comprehensive run-through of the entire system and tips for maintaining the overall system. We were kept informed all the way through the process. Ian and Michael went the extra mile at the end and noticed the UV Units were not working correctly because our custom system wasn’t providing enough pressure to turn the units on. They spent the time troubleshooting and custom fabricating a workaround on the fly, adjusting to ensure the system was working. We had our County Inspection the next day, and the County inspector was impressed and had great things to say about the installation. We hesitated for years to replace the furnaces because with an old farmhouse, everything turns into a “CUSTOM” Job and typically is full of heartache and pain with cost overruns and the “What We thought was.” Not with these guys. They came in, did a fantastic job, and finished not just on time, which has never happened at our home. They Finished Early !! Thank you to the whole team at Sunset Air. Especially our team Ian, Jason, and Michael, and the Electricians Tristan and Justin. We highly recommend Sunset Air."

Energy Efficiency Auditing questions, answered by experts

As you look for the right soundproofing drywall for you, you’ll likely come across the Sound Transmission Class (STC) rating. This rating measures a building material’s ability to absorb sound. The higher the number, the better the material absorbs rather than reflects sound, reducing noise transmission. The STC rating for drywall doesn’t mean it’s for the panel itself—it refers to the STC rating for the entire wall system, including the soundproofing drywall.

Depending on the level of audit you choose, a home energy audit will at least include a walk-through of the home to determine visible inefficiencies, but may include testing and a highly detailed inspection and report laying out the home’s inefficiencies and providing recommendations to fix those issues. The audit may also include a review of utility bills and mechanical testing. Consult your home energy auditor about the types of services they provide before hiring.

Energy-efficient windows cost more than other window types, but they can help you save on your monthly energy bills, get you some breaks on your taxes, and even increase the value of your home. According to Michael S. Regan, Administrator of the U.S. Environmental Protection Agency, when people invest in green upgrades like energy-efficient windows, they save energy, money, and more.

An average, 400-square-foot electric heated driveways consume approximately $3 per hour in terms of electricity. The price may slightly fluctuate depending on your local energy cost. A simple formula to calculate your heated driveway’s total wattage consumption is by multiplying the square footage by 50 watts and then dividing it by 1,000 to get the kilowatt number. Multiply that with your local energy cost per hour and there you have the hourly operating cost.

The best way to save money on home heating oil is to get large deliveries in the summer months when the prices are lowest. However, this method will only work if you have a separate storage tank or an unusually large primary tank. You can sometimes save money by opting into a delivery contract, as some companies offer set prices that they believe will sit at the average cost over the contract term. If the price of oil rises, you could enjoy some savings, but keep in mind that you might also pay a bit more if the price decreases.
