"Gridwise did the electrical work tied to our battery install. Stas gave a clear estimate up front, communication was easy, and the work looks neat. Passed inspection without drama. That’s the whole checklist for me."

"Omid was great to work with. Showed up when he said he would and did an excellent job. I appreciated his honesty when he recommended the less expensive option for my project. He could have easily said the more expensive option was the only way but he didn't."

"James, Graham, and Lazaro did a fantastic job on our home rewiring and panel upgrade. James came out fast for the initial quote, turned it around very quickly after the site visit, and got us on the schedule quickly after we decided to move forward. His price was extremely reasonable compared to quotes from other highly rated providers, especially considering that they included drywall patching, which most other firms didn't. At several points in the job, small changes needed to be made (moving switches, adding some lighting, removing old fixtures and their support, installing fans, etc.). We had good back-and-forth discussions in figuring out the right solutions, and all three team members were extremely responsive and cooperative in making sure these fixes were made as requested. They treated our house with as much care as their own. I highly recommend New Design."

Bathroom Fan Installation questions, answered by experts

Attic and whole-house fans improve a home's energy efficiency and comfort. They ventilate hot air from the attic, which reduces peak cooling loads, lowers reliance on air conditioning, and decreases indoor temperatures. This improved air circulation and expedited heat exit helps lower cooling costs, balance moisture levels, and enhance overall natural airflow, contributing to the efficient operation of other home equipment.

The square footage of your room will dictate the correct ceiling fan blade size. For example: 

  • Rooms smaller than 75 square feet require a fan that is 29 to 36 inches.

  • Rooms up to 175 square feet require 42- to 48-inch fans.

  • Rooms up to 350 square feet require 52- to 56-inch fans.

  • Expansive spaces over 350 square feet need a fan larger than 60 inches.

WD-40 in its liquid or aerosol form is highly flammable. Using it around live electrical parts, such as a bath fan, can generate fire and a dangerous condition. However, if you follow proper safety procedures, including disconnecting the power to the fan before working on it, WD-40 can help remove some of the grime that builds up in your bath fan.

Before committing to this new project, you’re likely weighing the pros and cons of attic fans. The good news is that typical roof vents can only ventilate 150 to 300 square feet per unit, whereas a single attic fan can circulate enough air to vent an entire attic. By moving large volumes of air within and out of the attic space, an attic fan can lower the temperature by 15 to 40 degrees Fahrenheit and reduce moisture to prevent mold and mildew.

For a 12x12 room, a fan between 36" and 50" will work, as it falls in the range for spaces up to 144 square feet. These size fans provide adequate air circulation and ensure a comfortable environment without being overpowering. Even better, they come in a broad range of styles, offering aesthetics and functionality, making them suitable choices for maintaining an ideal room temperature and enhancing overall comfort.
