"Handyman JC was on time and courteous. I needed some help with my AC, re-caulking my tub, and a special carpentry project (I needed a removable screen above my front door to keep birds out). Price was reasonable. I have more projects and plan to contact him again in the near future!"

"I had a problem with the airgap and the garbage disposal. I also needed some help with low water flow in one of my showers. Lano helped me resolve all my problems very promptly and professionally. He is very competent and does the job efficiently. I would hire him back for any of my other handyman needs as well."

"Hector came by and gave me a quote. Explained what I needed done to setup my level 2 EV Charger from Electrify America. They came out, showed up early. Got everything done on a timely manner, Even hardwired the station, instead of installing an outlet. Hook up my Car before they left and everything is charging and working great. Great business, Great employees."

Bathroom Fan Installation FAQs, answered by experts

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.

Yes, dust and pollen on a fan can trigger allergy attacks in many people. Additionally, fan blades can hold onto potentially dangerous bacteria particles before they die out. That’s why it’s important to keep all of the fans in your home clean and dust-free, which will help avoid any sickness or allergy flare-ups.

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.

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.
