Customers say: Quick response

"Tom from Synergy did the bid for under cabinet lighting install, however sent someone else to do the job. Originally discussed with Tom that he would use a regular converter box inside the cabinet and place a dimmer switch on the wall, but the other guy he sent wasn't aware of this and placed the dimmer converter in the cabinet. This has resulted in us having to use the dimmer switch inside the cabinet instead of on a wall switch -- not what I requested. Also, I discussed with Tom installing an additional outlet in our kitchen during the bid process. After he left I noticed he did not include that on the written bid. The guy he sent didn't know about it either. The outlet was installed however. Overall, I was charged $95 additional over the bid and didn't get exactly what I wanted in regard to the dimmer switch for under cabinet lighting. Both electricians were very nice and professional, but there was definitely a communication problem in regard to the installation of the under cabinet lighting. Perhaps I should have clarified the issue more strongly, or perhaps I didn't understand. Either way, I'm happy with the lighting overall, but not 100%."

"I had Local Handyman help me with a long list of “to do’s” I had been avoiding. They helped me with multiple interior and exterior projects. Their communication from beginning to end was fabulous. They helped me evaluate the scope of the work against other bids I received. Their work was professional, their men arrived on time and they completed everything in a timely and quality manner. I will hire them again."

Bathroom Fan Installation questions, answered by experts

For a 12x12 room, a fan between 36" and 50" will work, as it falls in the range for spaces up to 144 square feet. These size fans provide adequate air circulation and ensure a comfortable environment without being overpowering. Even better, they come in a broad range of styles, offering aesthetics and functionality, making them suitable choices for maintaining an ideal room temperature and enhancing overall comfort.

While it may seem like it makes sense to put a fan in the attic to cool it down, it won’t be as effective as installing attic fans. Ventilation installed near the peak of the roof, whether passive (just allowing heat to escape) or active (drawing the air up and out) will be more effective at cooling the attic.

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.

Yes, you can lubricate a ceiling fan without taking it apart. Ensure the fan is off and clean any dust around the motor area before lubricating. Apply several drops of machine oil to the top of the motor housing where the shaft enters or via the oil ports if available. Regular lubrication helps maintain smooth operation and reduces noise. If your fan lacks an accessible oil port, it may require disassembly or professional maintenance.

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.
