"We had serious issues with our second (half) story being consistently warmer than our first story, bringing with it very high electric bills. Peak Energy performed an energy audit that identified the issue and then sealed our attic (in the middle of a summer heat wave, no less) in 2 days. The team was professional and punctual and the discrepancy in our temperatures between the two floors went from >5 degrees to <2 degrees."

"Technician was running about 10 minutes behind schedule but called to let us know. He had to go to the hardware store because he did not have the correct outlet. We had to pay for the outlet which was not costly $10. Once he had all needed items he was able to get the job done quickly. He also answered some questions that we had about additional electrical concerns."

"Project went very well from quote through completion. Price was very competitive. Team was prompt, hard working, and neat. They made sure we were able to review the finished project areas before signing off on their work. All (sales, admin and install crews) were professional, polite and respectful of us and our property. We hope to see energy savings as a result of bringing the insulation levels up to recommended standards. Thank you EcoMaster!"

"I had another come out and service my furnace and when I did that they came up with like $1200 worth of work. So what I did, I thought I would get a second quote. So, a friend of mine told me about Bull City Heating & Air, so I called them and I told them exactly what the other one told me. They went under and basically said there was no problem. There was a switch or a turn that had to be tightened, so they tightened it. There was something else that needed to be replaced and they said "No it didn't need to, it had a little rust." They kind of got the rust off and basically said it was fine. So, they saved me all kinds of money. It was excellent and I decided right there, I am using them for now on. I think they are just in the ballpark with everyone else for price. It's not like they are the highest or the lowest. I don't remember that kind of thing. They didn't break the bank, which is nice."

We had Rick perform all the electrical work needed to bring our home office project to life, which included installing several new outlets, relocating several outlets, and installing a splitter for high speed data.  Rick had to make several trips to our house in coordination with the carpentry work being conducted, and he was very good about scheduling the dates and times for those visits.  Rick always kept us informed as to when he would be coming by and what he needed to do.  Rick was very friendly, professional, and provided us with high quality work.  We will use Rick in the future for all of our electrical needs.

Energy Efficiency Auditing FAQs, answered by experts

HVAC systems use the most household electricity. This major and essential system is responsible for heating and cooling your home all year round. Since they operate for a significant amount during the day, it consumes more energy than other appliances. 

A whole-house humidifier can positively impact energy consumption by improving heating efficiency. During colder months, humidified air feels warmer, which allows you to lower your thermostat without sacrificing comfort. This adjustment can lead to significant energy savings as your heating system works more efficiently. However, it's important to use the humidifier judiciously, as excessive humidity could potentially strain your cooling system in warmer months.

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

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.

Dryers are designed to use as little electricity as possible, but power is still required to run the motor that turns the drum and to heat an element that pumps hot air. Eco devices are available and may lead to cost savings in the long term, but you should run the figures before committing to an eco-friendly device as they are often much more expensive to purchase.
