"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

The extra insulation helps reduce energy costs by minimizing drafts and temperature exchange between indoors and outdoors.

Energy-efficient windows cost more than other window types, but they can help you save on your monthly energy bills, get you some breaks on your taxes, and even increase the value of your home. According to Michael S. Regan, Administrator of the U.S. Environmental Protection Agency, when people invest in green upgrades like energy-efficient windows, they save energy, money, and more.

Electric bills tend to be lower in spring and fall because people use less electricity during these seasons. Milder temperatures allow for less use of heating and cooling, unlike during winter and summer, which usually bring more extreme temperatures.

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.

While you can perform many routine home maintenance jobs yourself, it’s often a good idea to bring pros in for certain tasks. HVAC maintenance, fireplace and chimney inspections, foundation repairs, and roof inspections and repairs should be handled by professionals who know what to look for and can safely perform repairs. You may also find it helpful to hire a local house cleaning service to help with deep cleaning.
