He was very professional and following the Tune-Up asked if there was any other items that needed done or looked into that he could take care of. His services were very much appreciated and very professional. Lee"

"I had 5 vendors bid the job and they were the lowest cost, I did not feel I was being pressured to buy anything I did not want. They developed the plans and worked with the City to get the permit. Contacted me well ahead of time to setup an install date. They were there right on time, worked the whole time completing the project on time with no problem.

Did all the foot work with PG&E to get the meter turned on. and once everything was completed walked me through the monitoring program and provided a simulated PG*E bill and explained what the billing would look like. They provided the stamped plans, permit card and all the warranties that support the equipment install.

"Attic masters did a good job at my house by cleaning the ducts. I spoke to them prior and they were nice to me. they gave me several options and explain to me the difference between each one and they recommended me which one to choose. The work that they did was good and the people that did the actual work were very nice. I will hire them again.

Energy Efficiency Auditing questions, answered by experts

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.

Solar water heating systems are not one-size-fits-all. You'll likely work with a team of experts to get the job done—including solar panel installers, plumbers, and water heater installers. A specialist will help you decide if a passive or active system is best for your local weather, home layout, roof stability, and your budget.

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.

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.

Home power is measured in kilowatt-hours, commonly expressed as kWh. The average home uses between 800 and 1,000 kWh per month. Peak usage (and highest bills) occurs in the middle of summer and the depths of winter. Keeping on top of your usage during these crucial months will lower your annual average usage considerably.
