"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

You can check your home's humidity in a few ways. A simple option is to use a hygrometer, which you can find at a hardware or big box store. Your smartphone may also have an app that can measure humidity. Modern thermostats, particularly smart thermostats, are also able to measure humidity levels.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

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.

The number one culprit of high energy bills is older appliances, especially fridges and freezers that are left on all the time. These two appliances tend to last a long time, which is good, but it also means that newer models are usually significantly more energy-efficient due to upgraded technology. The second most common reason for a high bill is heating and air conditioning.

There are several signs that your house might have poor ventilation, including lingering odors, condensation on your windows, or mold and mildew. Your home may also feel stale and stuffy, or you might have trouble maintaining a comfortable temperature in your home. On top of that, you might develop allergy symptoms, such as sneezing, coughing, or headaches.
