"I called to set up a free consultation and was promptly met at the agreed upon time. We discussed my desires and how to achieve my project goals. I was given a quote and agreed upon the price for the garage work to be done the following week when I was free. The spray foam and "drill and fill" have been awesome! I have a 24K BTU AC unit in the garage that was unable to keep the temps low as there was so much heat in the garage all day. After the insulation was done it can hold the temps at 70F in the garage while barely turning on during the day. The attic above the garage tops out at 85F when it was over 110F outside, just amazing. We had them do a home energy audit and found that there were plenty of leaky areas in the attic and the insulation was 15 years old and about an R-10 level. It needed some serious work so we agreed to have it topped off with new fiberglass insulation. The guys came out and did and amazing job bringing me up to R-39 as well as keeping the house very clean while doing it. On both days they cleaned up after themselves and took great care of my house. I would wholeheartedly recommend them to anyone that could use more insulation!"

"Brad is passionate about energy savings and loves to help customers implement creative solutions. He thinks outside the box and brings valuable advice to the table, sometimes including ones that reduce his own fees.
By carefully considering all the facets of the situation, he helped me select a 2-ton unit to replace my aging, poorly installed 3-ton. Improvements to the ducting, etc. made up the difference. The house is now quieter and cools at least as well as before. The installation is also much more visually appealing than the last one. My new unit should last many trouble-free years, saving money all the while. I didn't check around to see if he was the cheapest, but the price was definitely reasonable.
We also worked together to install a small mini-split heat pump in an addition that no HVAC before. I wanted a unit he wasn't familiar with and had some picky ideas about how it should be installed. He was open-minded about how to make it work and the project was a success. His fees were pretty reasonable on this job, too.
I have at least one other project that I'll be doing with Brad this year. I wish more HVAC contractors were as creative and flexible as he is. This city would be a much cooler place!

Energy Efficiency Auditing questions, answered by experts

Leaving vents open but closing doors in unused rooms will probably not save money on your energy bill. Closed doors prevent the natural flow of air throughout the home, which could reduce the efficiency of the overall HVAC system. They could also restrict airflow into and through the return vents, making the HVAC system less efficient.

Dehumidifiers typically use 300 to 700 watts of electricity per hour, whereas portable dehumidifiers use about 40 watts per hour. The exact amount of electricity your dehumidifier will generate depends on its capacity and energy efficiency. Generally, higher-capacity dehumidifiers generate more electricity than lower-capacity units, but they also usually have better energy efficiency over the long run.

Yes, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.

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.

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.
