"Ferney oversaw a full renovation of my entire (small) bathroom. It was a complicated job and I had (unbeknownst to me at the time) selected an especially difficult bespoke floor tile, which ended up requiring enormous skill to install. Mr. Leal took the work exceptionally seriously, was capable, punctual, and completely reliable. He kept my small apartment clean throughout the job, and I felt very confident leaving him and his team in my home during the day while I was at work. While his pricing is not the lowest, I will 100% use his services again, and recommend him to anyone."

"Saul and his father came on time and inspected the attic fan, installed insulation washers, and added an override switch. The work was done in a professional manner, very neat. And I was shown photos of the final work (I did not want to climb into the attic). I highly recommend Three Brothers to anyone who needs electrical work."

"I needed to clean up the interior of a hall closet before new shelving and cabinetry could be installed through a different vendor. The work entailed removing some wood planks that supported the previous wire shelving, patching a large hole in the drywall, and resurfacing and painting those spots. I already had the paint on hand. They did an excellent job, had the best pricing relative to competitors, and were able to schedule the work very quickly after I reached out. Would definitely hire them again for handyman-type work -- and probably will at some point."

"The work that Mr Nesbitt did for us was to replace a bathroom fan that had failed. I do a fair number of home projects myself but didn't have the time for this one, and as anyone who has replaced a bathroom fan knows, this job is not as simple as it might seem. Here's how I would summarize the experience of working with Mr Nesbitt: Advantages - He was responsive to initial inquiries about the service as well as to other questions leading up to starting the job. - The quoted cost was reasonable given other estimates that we received, and he completed the job for the agreed price - He found a fan unit that met the specs that we requested (especially for sound level) - He was able to start the job within a matter of days after we agreed to move forward - He arrived on time on the day that we arranged with him to do the work - He completed the work exactly as we had discussed and within the time that he estimated it would take - He left the area clean after he completed the job - The workmanship of the work he performed was very good Disadvantages - I cant think of any The overall experience of working with Mr Nesbitt was very good, and we would definitely work with him again if other projects come up."

Over the past few weeks we have had various projects completed, including, exhaust fan installation, stairwell repair, dry wall repair, exterior dormer and trim replacement and gutter/downspout painting.

Pedro, Kevin and Antonio in particular were exceptional in going above and beyond to produce truly beautiful work. The craftsmanship and precision displayed by these technicians was extraordinary and they were an absolute pleasure to have in my home.”"

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 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.

There are many signs of a bad AC fan motor, including if the fan blades don’t spin when the AC kicks on or if they keep spinning when the AC is off. The AC fan cools down the condenser coil, so a faulty motor can also cause the system to overheat. Unusual noises in the exterior AC unit, including grinding or rattling sounds, may also be a sign that the AC fan motor is worn out.

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.

Every municipality has its own codes. But generally speaking, all bathrooms must have some ventilation, whether it's a fan or a window. Check your local building codes before doing any bathroom fan installation to make sure you are meeting the code requirements. A reputable electrician or bathroom fan installer will be able to answer this question.
