"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."

"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, most audits include a report with prioritized recommendations for improving energy efficiency. Confirm with your auditor.

Installing weather stripping or upgrading to insulated panels can improve efficiency.

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.

After you receive your audit and report, review the findings and determine which of the prescribed changes you want to make to improve your home’s energy efficiency. Start by contacting the type of professionals recommended by the auditor who can help you remedy the issues discovered during the audit. Prioritize the projects by urgency, importance, and budget. Then, gather estimates from several professionals, remembering to verify any necessary licensing and experience information.

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.
