"Tom is an expert in this field. He is a wealth of information during the energy audit. He is complete and takes the time to ensure he is measuring things correctly and most importantly to answer any questions so you understand. You need to try this service if you live in an older house. Our house was like night and day after the insulation work in walls, floors, and some ceilings. The house was easier to heat. An added bonus was how quiet it became. Tom will come back in the spring for another energy audit after we finish some final work. This will find any gaps and help prove the benefits we have already seen. Tom came back and did a post review to confirm the steps and work. While we saw and felt results, the technical results were amazing. What great follow through by a contractor! I have hired him for again for additional work as he does other home efficiency recommendations and work besides insulation. Highly recommend using and taking his advice."

"I recently purchased a house that left a lot to be desired when it came to the wiring, panel and fuse boxes in the basement. The service was only 100 amp as well. I wanted to upgrade to 200 amp service and get the rats nest of wires in the basement fixed. I searched Angie's List and found Mike's Electric. He had a good rating and great reviews so I gave him a call. Despite that fact that I was an hour away, Mike had no problem coming out to take a look and provide me with an estimate. He originally quoted me between $1900-2000 to do the upgrade and installation. He was very flexible in working with me and my hectic schedule and called to schedule the work within a week of doing the estimate. He maintained the original quote despite the fact that the work was probably more extensive than what he first realized. They cleaned up very nicely after themselves once the work was completed and he even called the next day to ensure that I wasn't having any issues. To sum it up, Friendly, Courteous and Professional. A top-notch job and I'd hire him again in a heartbeat."

Energy Efficiency Auditing FAQs, answered by experts

String lights require electricity, but not an excessive amount, especially when compared to other lighting fixtures. LED rope lights, for instance, consume around one watt per foot. Running six or seven light strings simultaneously should only cost you around $10 to $15 each month. You can save even more money by remembering to turn off your lights during daylight hours. 

To find a reputable home energy auditor, start by researching local companies that offer the service and check their reviews, methods, and certifications. The most reputable professionals are often Home Energy Professional (HEP)-certified by the Building Performance Institute (BPI). You can also consult the Department of Energy’s certified list of energy auditors or use a state licensing tool to review local guidelines and ensure you are hiring a certified professional for your area.

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.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

Yes, Tesla Powerwalls are worth the upfront costs, as you can recoup your investment within six to eight years. Plus, they provide peace of mind that you'll have power during a power outage, and, depending on the system you install, you can become energy-independent. While they may be more expensive than other solar power systems, they offer higher battery capacity and lifespan.
