"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

Audits include inspecting insulation, HVAC systems, windows, and appliances to identify energy inefficiencies.

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.

DIY is possible with basic tools. Professional audits provide comprehensive assessments and tailored recommendations.

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.

R-value measures an insulation material's thermal resistance, indicating its ability to resist heat transfer. A higher R-value signifies better insulation performance because the material is more effective at slowing heat flow. The R-value depends on the type, thickness, and density of the insulation material, such as fiberglass, foam, or cellulose. Each inch of insulation typically provides an R-value between 3 and 8. There is no single universal R-value; the optimal choice depends on your climate zone. Colder climates require a much higher R-value than warmer ones to maintain energy efficiency, keep the home warm in winter and cool in summer, and manage costs.
