"We were pleased to work with Greg Mair who came to.our house the night of Jan17, 2024 after our 14 year old furnace died. He reviewed our entire system and made recommendations that fit our needs correctly. He arranged for a new furnace to be installed the next day and provided us with space heaters to be used until the work was completed. We will definitely call on Greg for any future needs."

"Matt came right out and fixed two light switches that weren't working for one of my customers. He was quick, efficient and very professional. We especially appreciate it because it was done a Friday and we called at the last minute. We highly recommend them and will call them for all of our electrical needs in the future!"

"They were extremely professional. They knew exactly what we were talking about when we said what we wanted and gave us a good price. They didn't come exactly when they said they would, but as soon as they realized they would be late because their prior job was harder than expected, they called ahead. We had plenty of time to reschedule our day. We had them install three fans, including new fan control switches, and all three fans are solidly in place with no glitches. Overall, this was a great experience and I'll probably head straight for them the next time I need electrical work done."

"Adam and Pat do amazing work. They have been doing any work on the house we need for many years now. Most recently they fixed an internal sliding door which came off its tracks as well as installing handrails on the outside steps of our house. We would highly recommend Adam and Pat for any jobs you need completed."

Bathroom Fan Installation FAQs, answered by experts

Most duct booster fans are not designed to run continuously, though some models can be programmed for constant operation. Typically, they are controlled by the user via a switch, controls on the unit itself, or by being wired to the HVAC system's thermostat. Wiring the fan to a thermostat allows it to run automatically only when heating or cooling is active, which saves energy and is an effective way to activate the fan only when needed to address issues like uneven room temperatures.

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.

It depends on your budget and cooling needs. Whole-house fans keep your home breezy by pulling in cool air and pushing out hot air. In places with milder climates, they can replace air conditioning. On the other hand, Attic fans focus on keeping your attic cool—not your entire house. Often, whole-house fans cost more than attic fans, with installation ranging from $600 to $3,600.

Leaving an exhaust fan on constantly isn’t ideal. While it helps remove moisture and odors, continuous use will lead to wear and tear, higher energy costs, and even fire risks if the motor overheats. Bathroom fans should run for 20 to 30 minutes after a shower, while kitchen exhaust fans should be used only when cooking or clearing air.

Yes, ceiling fans come with a few other features that help with function, style, and convenience. Multi-speed fans can give you specialized control over the airflow. Consider getting one with an integrated light to save ceiling space. Some ceiling fans come with a remote control that enables you to change direction without climbing a ladder. Of course, you can also consider installing a wall switch to enjoy that convenience.
