"I hired K & K to install a range hood. There was no electrical there previously so they had to run electric. I also had them install a new light fixture and remove an exhaust fan. K & K did excellent work and even repaired an electrical box that another contractor had installed. I was given a great estimate and was charged the estimate price. Would definitely use again and recommend."

"So glad we chose B.C.G. to do the work we needed on our house. They were very professional, reliable and prompt. Bryan checked in each day to plan for start time and supplies, no surprises. They did great work from installing penny tile molding and bead board in the bathroom, repairing drywall, hanging interior doors and replacing our block retaining wall. Along with the excellent work they cleaned everything each day- We plan to have them back for the rest of our home improvement project big and small."

"I asked Mr. Nesbitt to do an update in two bathrooms which included replacing the toilets, faucets, lights, and painting of one bathroom. He was very responsive to my communications. He started the work on the day agreed upon and advised of any change in arrival times. He was very skilled and proficient in how he did the job. He cleaned up and removed the discarded items. Afterwards, I did notice a small leak in under the sink in one of the bathrooms, but Mr. Nesbitt came back the next day and quickly fixed it. Overall, he did excellent and high-quality work. Anyone would be very pleased with his services."

"Tony and AJ showed up on time. They were very friendly and got right to work. Because the original ceiling fan was not installed properly, AJ had to make do with what was installed in the ceiling. He explained everything as he did it and did not push for an option that I didn't want. The end result is just what I wanted. Both Tony and AJ were very professional. I highly recommend them for electrical work and will call them in the future for other projects. "

Bathroom Fan Installation FAQs, answered by experts

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 whole-house fan works best to pull chilled and dry air into your home in the early morning hours and at night. This system allows you to close your windows after turning off the fan and trap the cool air inside. You can run your whole house fan continuously for maximum ventilation and fresh air, or you can turn it on for ten minutes or so at a time to introduce cool, fresh air as needed.

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.

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. 

The direction your ceiling fan spins helps create comfortable airflow in your home and can also help cut down on energy costs. 

During summer, your ceiling fan should spin counterclockwise. This will push cooler air downward in a column and help lower your room’s air temperature. In the winter, set your ceiling fan to spin clockwise and at the lowest speed setting. This will pull cool air upwards, displacing the warm air that pools towards the top of your ceiling and bringing it down towards the floor.
