"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."

"The whole process was not pleasant. We went with Arrow because of the good reviews, but the insulation process was anything but easy. We have an older home that had nailed in dry wall. We decided to have the installation done through the home exterior in order to minimize clean up (we had a 3 month old at the time that we didnt want exposed to the dust/insulation particles). When the insulation was being blown in, many of our dry wall nails began to pop through the dry wall. We were never made aware of any of the potential problems with blowing in insulation through the home exterior, and this process created far more work than we were expecting. As for the exterior of our home, we were left with many siding boards damaged (which thankfully Arrow decided to pay for). Some of our siding could not get removed, and holes were instead cut into our siding. When these were initially patched, they looked awesome, but after only 1.5-2 months, the patch work began to show cracks, and now every hole that was created is visible from the street (some of the plugs have even been able to be moved around with very little pressure). This process has been a nightmare, and our home exterior, after almost 3 months, still is not what it was before the work was done."

FAQs for energy efficiency auditing projects in Roy, WA

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

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.

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.
