"Marshall Insulation was great. They arrived early and worked quickly and efficiently. For a messy job they made sure it was clean when they left. Jeff did a good job explaining the SRP programs,"

"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

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

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

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.

Keep the unit full but not overloaded, ensure door seals are tight, set correct temperatures, and avoid frequent door openings. Position the appliance away from heat sources for optimal performance.

You can increase your home’s load factor by replacing fuse boxes with a circuit breaker, hiring a licensed electrician to upgrade your electrical panel, upgrading wiring, or installing subpanels. An electrical inspection by an expert can help determine the state of your current electrical systems and how they can be improved.
