"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

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.

If you think your fan needs to be oiled, the first thing that you have to do is cut the power to the fan. The best and safest way to do this is by flipping the circuit breaker that leads to that room.  Depending on the model of your fan, you may need to remove a cover. Look for a hole labeled oil. If there isn't one, check the manual or look for schematics online. Once located, use the recommended lubricant or spray. 

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.

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.

Regularly clean fan grilles, check for dust buildup, and ensure proper venting to prevent mold growth.
