"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!

"Well, it was fun as well as giving me just what I wanted for my house.....more light, more privacy, and aesthetics. The nice thing about Tim, aside from the fact that he's a nice person and very intelligent, and gifted in his field, is that he listens and makes you part of the process. I felt totally at ease and secure giving him keys to my house for work that was done when I wasn't there. My house maintains it's old feel (he blended the new with the old) as well as contributing to making it an even more beautiful house."

Energy Efficiency Auditing FAQs, answered by experts

Attic and whole-house fans improve a home's energy efficiency and comfort. They ventilate hot air from the attic, which reduces peak cooling loads, lowers reliance on air conditioning, and decreases indoor temperatures. This improved air circulation and expedited heat exit helps lower cooling costs, balance moisture levels, and enhance overall natural airflow, contributing to the efficient operation of other home equipment.

Solar water heating systems are not one-size-fits-all. You'll likely work with a team of experts to get the job done—including solar panel installers, plumbers, and water heater installers. A specialist will help you decide if a passive or active system is best for your local weather, home layout, roof stability, and your budget.

Replacing a window frame will improve your home’s energy efficiency if the old frame is cracked or damaged in a way that allows unconditioned air from the outside into your living space or if you upgrade to a more energy-efficient window frame material. Aluminum is the least energy-efficient window frame material, followed by vinyl and wood. Fiberglass and composite frames are the most energy-efficient.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

Yes, these services often increase home value by preventing moisture-related issues and enhancing the usable space in basements or crawlspaces.
