"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."

"They come once a year. They don't appear to have a standard checklist for what their technicians are suppose to do. Consequently, everyone does something different. In addition to that, they don't appear to have the appropriate training because they come up with various levels of conclusions. One guy might say everything is fine, another guy says you need a new air conditioner. Another guy says a new humidifier and a new filter. It's nice that they come and look at the furnace. I can get about as much out of it if I send them a picture. I had this done for about 10 times and that's what's occurred in over 10 visits. Some people re excellent. They do a wonderful job. Other people are clueless. They want his and they want that. The air conditioner is still running and that was two years ago. On the other hand because of that service contract, if there's any problem, I go to the top of the list for prioritization. I get an immediate response for anything I call in. For the most part, I think it's the labor, there's no cost on minor repairs. I pay them $28 a month. They come when you call them and they do a reasonable job."

"Initially we made contact and we couldn't set a date. I didn't hear from them and tried them back in the summer. They never called us back. I feel there was a lapse in the communication. The people on the phone were very professional and nice -- but there was just no follow through."

"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

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.

Depending on the level of audit you choose, a home energy audit will at least include a walk-through of the home to determine visible inefficiencies, but may include testing and a highly detailed inspection and report laying out the home’s inefficiencies and providing recommendations to fix those issues. The audit may also include a review of utility bills and mechanical testing. Consult your home energy auditor about the types of services they provide before hiring.

Fireplaces can theoretically help you save on heating bills if you lower the temperature throughout the rest of your home and heat only a single room that you occupy using the fireplace. However, in most cases, homeowners won’t save any money on heating bills. Gas and electric fireplace inserts could actually lead to a spike in your respective energy bills if you use them frequently, and if you don’t keep up with chimney maintenance and repairs, your traditional masonry fireplace could actually be a source of heat loss in the winter.

Costs depend on the property size, audit complexity, and whether additional testing (e.g., blower door) is included.

Motion-sensor lights use one watt while on standby and five watts while turned on. They’re usually on for one hour over a 24-hour period, bringing the total wattage to about 28 watts per day. LED lights use around 6.5 to 8 watts while on. If you leave an LED light on all night, with night ranging from 10 to 14 hours, you’re looking at using 65 to 112 watts a night. You can minimally cut your wattage in half by switching to a motion-sensor light.
