Customers say: Quick response

"Several years ago I hired ESV to install new panel lighting in my crawlspace, prior to it being encapsulated; the electrician worked in a dirt surround environment, installed (4) 4-foot lights, and ran a separate line to the panel box. I was impressed with the work ethic and professionalism of ESV's electrician. Years later I requested a line-item quote (by room) for re-wiring my entire house. Dan provided a succinct quote and coordinated the work permit; he and his crew re-wired each room individually (which fit both our schedules per room). This quote also included a new, updated panel, with Dan working with the electric company to shut down power to the house for panel replacement. I definitely trust Dan and ESV with all my electrically needs."

For over 30 years, Root Electric Services has been serving the Northern Virginia area as a residential and commercial service electrician. The company is now in its second generation, being founded by Bill and Janice Root in 1986, and now growing under the direction of their son, Bill. Root employs a small number of professional, highly productive, and friendly electricians. \n \nRoot Electric sets itself apart from competitive companies by providing comprehensive, up-front pricing. That means Root Electric provides bids that include all of the components needed for each specific installation. In contrast, some contractors omit certain critical parts from the bid to win the job, then add them back in as a change order after the contract is signed and work has begun. Our customers appreciate that we tell then what they are buying, then deliver what we promised at the price that we quoted. \n \n

"It went very well. Jake did a great job of replacing my fan motor -- no problems. He was very thorough and he is very professional. He checked to see if there were any other problems, and found none. He arrived on time and was very polite. I like this company very much."

"Terrific, we decided to go w/ Stoneberger because their sales representative spent time advising and guiding us through the options, the colors and styles of doors. She listened to what we thought we wanted and helped us find the right solution. No other sales rep we met with offered that customer service. She also followed up on time and was super easy to work with once we decided on specific doors. Installation also was on time, efficient and went very smoothly. We had one issue that arose b/c of the age of our house and Stoneberger addressed it quickly and beyond fairly. Highly recommend them."

Bathroom Fan Installation FAQs, answered by experts

While it may seem like it makes sense to put a fan in the attic to cool it down, it won’t be as effective as installing attic fans. Ventilation installed near the peak of the roof, whether passive (just allowing heat to escape) or active (drawing the air up and out) will be more effective at cooling the attic.

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.

A small wobble isn’t worrisome, especially when you’re using your fan at top speed, but a significant one is. Ball joint fans, which are used on sloped ceilings, are more likely to wobble than a standard fan based on their design. But even then, you shouldn’t see significant wobbling, as this can be a sign of a bad installation.

Fan power is measured by CFM, or cubic feet per minute. For every 1,000 feet of square footage in your attic, you need a minimum of 700 CFM. Steeper roofs may need larger fans or about 840 CFM.  You can figure the size of attic fan you need by multiplying the square footage of your attic floor by 0.7. (multiply by 1.2 for a steep roof and 1.15 for a dark roof). That number is the CFM required for your fan to run efficiently.

Selecting the right size wood stove fan depends on the size of your stove and the room it heats. Larger stoves or rooms may benefit from fans with larger or multiple blades, as these can move more air efficiently. Consider the fan's specifications and airflow capacity to match it with your stove's heat output for optimal performance.
