"Smart Electric was pretty good to work with. We were especially pleased with the technician, Gram, who was kind, communicative, and thorough with his work. He came back multiple times for final touches and adjustments after the inspection report. In general, there were a couple of communication gaps with the company when initiating the project and day 1 of work, but it got settled by the end. We are pleased with our new heat pump and furnace."

"I just bought a large older home and received my first electric bill.....wait for it.....$850 for this month! Ouch!! I decided I needed to figure out where to start and what to replace and where and how exactly I was burning through so much energy. I called Evergreen Energy Services. Kirk was great! He showed up on time and with a smile. He was very professional and explained exactly what tests he would be preforming during my homes energy audit. He showed me all of the areas my home was not sealed and letting cold air in and letting all my warm air out. Kirk offered ideas and advice on making my home more energy efficient, lowering the heating bills and saving money. Kirk does not sell Energy Products so I felt like I got a very non bias energy consult and was not pressured towards certain Brands or Systems. I would definitely recommend Evergreen Energy Services! Megen 😊"

"William and Matt from HSR showed up on time and wore masks. I am absolutely blown away with the quality of their work and responsiveness to my requests. My project involved replacing our current furnace with a new furnace which is now installed in the attic. They promised me much reduced noise and greater energy efficiency. All goals 100% achieved. Highly recommend William, Matt and his team of workers."

"Heather is awesome! She was punctual, knowledgeable, and courteous, and took the time to inspect everything thoroughly. She showed me how to change out the furnace filter and even rearranged the rocks in my fireplace to give it a fresh look, above and beyond! She also troubleshot some work done last year (by another contractor) that was not done properly and gave good advice. It's rare I feel good about shelling out a few hundred bucks for maintenance work, but Heather delivered a high quality service and left me with the confidence that everything was checked correctly and is in good working order. Thank you!"

Energy Efficiency Auditing FAQs, answered by experts

The answer is a resounding yes, as dishwashers save significant water and energy compared to washing dishes by hand. The difference is so drastic in fact that those who use energy-efficient dishwashers can expect savings of over $450 per year. This is because dishwashers use less water, they wash at a higher temperature than a hand rinse, and you don’t need to rinse them after washing. New dishwashers use around 4 gallons per load, whereas washing by hand can use up to 2 gallons per minute.

Heat pumps transfer existing heat instead of generating it, using less energy. Compared to baseboard heaters, they can reduce heating costs by up to 50% and provide efficient cooling, lowering electricity bills and carbon footprint.

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.

While some aspects of an appraisal, such as comparable properties nearby, are out of your control, there are several steps you can take to potentially increase your home's value. Make any necessary repairs and upgrades before the appraiser's visit, as they can only value what is currently part of the home, not its potential. Examples include renovating older areas, updating landscaping to boost curb appeal, and staging your home. You can also provide the appraiser with the cost of recent upgrades, which may increase your home's value by about 50% or more of what you paid for those improvements.

The number one culprit of high energy bills is older appliances, especially fridges and freezers that are left on all the time. These two appliances tend to last a long time, which is good, but it also means that newer models are usually significantly more energy-efficient due to upgraded technology. The second most common reason for a high bill is heating and air conditioning.
