"We highly recommend this company. Kirk was on time and did what he said he was going to do. A complete and thorough energy audit was done including negative pressure test, smoke stick testing, thermo imaging evaluation, photos up in the attic and ending with a summary of what he found and advice on prioritizing projects. We opted to take notes because we didn t need a formal report. Kirk was very pleasant, patient and answered our multitude of questions. We learned a lot from him and we really appreciate all of the time he spent with us helping us understand the what s, why s and how s that need to be done. He went above and beyond what we expected and we are very grateful for it."

"Perfectly! The installers, Dan and Tristan, were timely, professional and clearly experts in their field. Erik Hoover, our estimator, couldn't have been more timely and professional. I've worked with this company for 20 years and have never been disappointed."

"I called Home Squad not knowing what to expect, I haven't heard of this company. But, I'm GLAD I did, Home Squad was amazing throughout the entire experience from calling them and setting up an appointment to meeting a wonderful electrician. Tyler was his name. Tyler was very personable and made sure he answered all my questions, I would highly recommend calling this company. They are greatly trained techs that come out and diagnose and explain things like no other. They installed a Tesla charger for my home in Bellevue and I can't wait to have them install a solar roof to my home. I have been running a generator for quite some time and solar shingles look beautiful on homes, I am ready to switch and have this team take care of it for me."

"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

Yes, pros suggest units with high EER ratings for energy savings.

No, it isn’t necessary to have energy-efficient windows. However, if you care about your energy bill and making your windows more energy efficient, fixing any heat, UV, or air transfer issues is an excellent way to lower your bills and keep your house cooler in the summer and warmer in the winter.

ENERGY STAR®-certified windows are the most energy-efficient windows on the market. This certification means that the window meets strict efficiency guidelines set forth by the Environmental Protection Agency. While they might cost more upfront, they can save you money on your energy bills in the long run. ENERGY STAR®-certified windows lower household energy bills by an average of 12% annually.

Smart home upgrades can be worth the money. Several upgrades, including smart thermostats and ceiling fans, can help reduce your energy bills. Others make life more convenient, freeing up your time to do what you love (or get more work done). And some smart home upgrades, such as entertainment systems, simply make life more enjoyable. All are worthy causes.

DIY is possible with basic tools. Professional audits provide comprehensive assessments and tailored recommendations.
