"Switching from a gas car to an EV entails a sharp learning curve. Having a charger installed with an outlet that didn’t previously exist isn’t an easy job. Josiah installed a new outlet, changed the paneling, and set up my charger in two hours. It’s hard enough just to get an electrician to show up. Make your life easier and just hire Josiah to get the job done right."

"Besides a wiring upgrade, I had a humidifier installed on my furnace, a whole house surge protector installed, a mini-split heating/cooling unit installed on the 2nd floor, multiple outlets added and upgraded, the furnace and outdoor AC compressor cleaned, and even a couple of light fixtures and ceiling fans replaced. Rick is thorough, friendly, efficient, transparent, and very patient when it comes to explaining the how's and why's of what he's doing to a customer who really knows nothing about electrical. I will absolutely use him again for any and all of my electrical needs, and feel 100% confident in referring him to friends and family."

Bathroom Fan Installation questions, answered by experts

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.

Your blower motor may make a loud sound if the bearings overheat or wear down as your system ages. You may also hear loud noises coming from your blower if it’s struggling to pull in air due to dirty or damaged ducts, closed or blocked vents, or a dirty air filter. Typically, this causes a loud whistling sound.

The most efficient ceiling fan height is 8 to 9 feet from the floor to the fan blades. For ceilings higher than 9 feet, a downrod can be used to lower the fan to the optimal height. This positioning ensures adequate air circulation and maximizes the cooling effect. Remember, fans should be installed at least 7 feet above the floor for safety.

Ceiling fans are very often worth the investment because they improve comfort in your living space and help reduce utility bills. In the late spring and early fall—and even in the summer in some areas—homeowners with ceiling fans can often get away with open windows and fans, which can cut down on cooling bills and also reduce wear and tear on the HVAC system. Over time, ceiling fans can pay for themselves by saving you money on electric bills and air conditioner repair and maintenance.

You should generally avoid using WD-40 on a ceiling fan. While it might quiet a squeak temporarily, it is primarily an anti-corrosion and water displacement agent, not a true lubricant, and can damage the fan's components over time. Most modern ceiling fans have sealed bearings and do not require oiling, so a squeak may indicate another issue. For fans that do require lubrication, it is better to use a light machine oil, 30-weight motor oil, or a lubricant specifically designed for ceiling fans.
