"John was awesome! I had three other guys come out and never come back. He fixed the bigh problem we had with our shower wall, reinstalled the faucet, and tiled a bathroom window. Very professional, on time, quick. I've already been telling my friends if they need a tiler, this guys the one! The price fair, and the quality definitely worth it."

"WONDERFUL AND ALWAYS ON TOP OF THINGS! I highly recommend Best builders group. We used Best Builders Group to completely remodel our large kitchen. We received several estimates from 4 other construction companies and Best Builders Group was not the lowest nor the most expensive. But, Zohar was able to present us many sets of photos from their past projects and also seemed the most truthful from the other ones. We needed to have our kitchen fully complete within 5 weeks because we didn’t want to move in to our new house without having the new kitchen. Zohar and his skilled team did complete the kitchen project on time and a little bit less than the agreed budget. After the kitchen was complete, Zohar and his people came over several times in order to do some small adjustments as we asked (things that we can ask only after we start using the kitchen). To be more specific - they came over 3 months after the work was done. We currently have new plans on remodeling our bathrooms and Zohar at Best Builders Group will be for sure the first and only team we call."

Bathroom Fan Installation FAQs, answered by experts

When maintained and repaired when necessary, your whole-house fan can last between 10 and 20 years. Check your warranty when purchasing the unit, as it will typically only cover between 5 and 15 years. Its longevity will also depend on your local climate and how much you use the fan. Having a professional size your fan appropriately for your home size will also help ensure it doesn’t get overworked, which can limit its lifespan.

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 your fan blades are spinning and there is no airflow, your blade pitch may be too flat, or your motor is failing. Adjusting the pitch is a simple DIY task if you have the tools. A failing motor is a bigger problem. You may need to replace your ceiling fan altogether. But fret not, we’ve got a guide for that!

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.

Exhaust fans push air out of spaces, removing moisture, heat, odors, and pollutants. They vent air outside through ducts, preventing mold and improving air quality. Unlike ventilation fans, which circulate fresh air in and out, exhaust fans focus solely on expelling unwanted indoor air.
