"Awesome job and service from Seatown. I called Seatown after looking at the reviews online. My main breaker had tripped several times over the course of a month, very concerning since I knew my 82 year old house had knob and tube wiring. For the initial assessment, Craigan W. came out and explained that my house only had 100 amps coming in. I really had no idea what that meant and Craigan took the time to tell me about the amp usage for the major appliances. Apparently, using the washer, dryer, oven and dishwasher at the same time was taxing my system to the limit. Craigan went through the house, noting items that were not up to code and reviewing my options with me. He was very thorough and professional. Although it was very expensive, I decided to have the whole house rewired along with updating the breaker box/increasing the amps to 200. The next step was the installation. The installation team consisted primarily of Kurt Hodge and Tyler. On the first day, they walked through the house and garage and explained how the work would proceed. Kurt and Tyler were a great team. They work so well together and worked solidly every day. There was no downtime for them - they were working hard every day. Each evening they would clean up, pack up the trash and vacuum up what they could. They would review with me what they did that day, and what they were going to work on the next day. The job was scheduled for 9 days but they completed it a day ahead of time. Part of this might have been the extra help they had a few of the days from another Tyler and someone else whose name I don't remember. All of them were great, very friendly, patiently answered all of my questions throughout the process, and always wore masks. I would highly recommend the whole team, especially Kurt and Tyler. Also, a shout out to the office staff. I spoke with a number of different people at the office and was so impressed with how friendly they were. Kudos."

For 45 years we’ve been making Puget Sound homes the most healthy, energy efficient and comfortable homes in the country. Our experienced team brings decades of expertise installing and maintaining the most innovative and efficient technology. As a Mitsibushi Cooling and Heating Diamond Contractor, Evergreen Home Heating and Energy has some of the world's most efficient and innovative products available.
"We had Evergreen Home Heating and Energy install a new water heater and furnace, and unfortunately, the quality of their work has been disappointing. Recently, I noticed several issues with the intake and exhaust pipes. Several hanger straps attached to the wall are broken, and one of the joints on the water heater exhaust pipe is leaking water. I suspect this leak is caused by the imbalance due to the broken hanger straps. I expected a professional and reliable installation from Evergreen Home Heating and Energy, but these problems indicate a lack of attention to detail and quality. Based on my experience, I cannot recommend Evergreen Home Heating and Energy. If you’re considering them for your home needs, be cautious and perhaps look elsewhere."

"I have used this company before for plumbing repairs, and I have to agree with many of the reviews. They were prompt, professional and I thought they charged a reasonable fee. So when I decided to install a water softener in my home, I immediately thought of them and asked them for a price estimate. I was told that they charged $69. When I balked at that, they said they would waive the fee and send someone out. I thought that was really nice of them to do that and was looking forward to getting their estimate. I was going to supply the water softener myself, so all I needed was to have them install it. I am fairly handy around the house myself and I knew that this wasn't going to take much more than a hour or so of their time and a few parts. It was not a big job. I was absolutely floored when I go their estimate. They wanted $4,243 for installation only. I find it hard to believe that they would want so much money for so little. I truly felt like they were trying to rip me off. I found a licensed plumber on Angis's List who did the job for $600, which as about what I had estimated the job would cost. I was extremely disappointed in CM Heating's highly overpriced estimate for a simple job. It certainly didn't inspire confidence in the company. They have lost my business forever."

"This review is long overdue in my praise of Washington Energy Services for their customer service, pricing and workmanship ! My first interaction was in 1999 when they installed windows throughout my house. They are still in excellent condition. I might note I called them over 20 years later to inquire on how I could repair a broken slider and they sent someone right out, charging a very nominal amount to repair it. In 2020, I needed to replace my hot water tank, and the extremely knowledgeable Christy presented several options, answering my many questions. I settled on one with a booster that seemed to best fit my needs. Finally, in December 2023, I purchased a new gas furnace from WES. I had a minor issue with a fan switch and they responded quickly to rectify the situation. Within the past two months, I seemed to be having an issue with my thermostat (something they had not installed), and the manager, Greg, came out twice with his crew to explore the problem. Today they installed a new thermostat FREE OF CHARGE! Their excellent response and customer service is beyond any company I have hired. And I particularly love that they are family owned and have been around for decades. Their employees seem to be there for the long haul, which speaks highly of the owner. I refer all my friends and family and I won't go anywhere else for services that they offer. Many thanks to the staff I have interacted with over the past 25 years!"

Energy efficiency auditing services FAQs
An energy audit costs about $420 on average, ranging from $100 to $2,250, depending on the size of your home, property, location, and the tests the auditor needs to perform. Keep in mind that the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit covers up to $150 of home energy audit costs. Common energy audit tests include:
Blower door test: $350
Duct testing: $100
HERS test: $375
HERS certification: $200
Infrared imaging: $200
To find a reputable energy auditor, find a local company that offers energy audit services. Research the company’s reviews, methods, and certifications to find a reliable professional in your area. The most reputable energy audit companies are HEP-certified by the Building Performance Institute (BPI). Be sure to check our state licensing tool to review the local energy auditor guidelines to ensure you’re hiring a certified professional.
The difference between an energy auditor and a home inspector is primarily in the purpose of the inspection. The energy auditor conducts tests in your home to determine the energy efficiency levels in areas like windows, insulation, and doorways. The auditor then makes recommendations for ways to improve a home’s energy efficiency.
A home inspector examines various structures of your home to determine that everything is up to code and gauge the condition of features like the roof, foundation, HVAC, and electrical. The home inspector reports on the overall home and makes repair recommendations.
Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.
The three levels of home energy audits include:
Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.
Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.
Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.
