"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

"It was okay; it was nothing more than I expected. It was so cheap that I thought I'd give it a try and maybe we could get some insight into ways to make our house more energy efficient, it's already pretty efficient, and the option that they offered was just cost prohibitive. So honestly, I thought that it was more of an opportunity to get a qualified lead to sell their service to. But we did get some artefacts, and for the money I suppose that was worth it."

Energy Efficiency Auditing FAQs, answered by experts

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

While many states require all new construction to undergo blower door tests, it’s not a requirement for existing homes. But in both cases, a blower test helps confirm that the contractor has sealed the exterior, that the type of ductwork installed is functioning properly, and that your home is as efficient as possible.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

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.

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.
