"Joe from Rebeccaâ s Handyman Services was able to come out the same day I called about removing old, cracking caulk around my garage door. Price was very reasonable and he did a great job, and made sure to clean up the area afterwards. Iâ ll be using him again for other â honey-doâ items in the near future."

Bathroom Fan Installation FAQs, answered by experts

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.

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!

Regularly clean the blades, check for loose screws, and lubricate moving parts to prevent noise and wear.

It is unlikely that a ceiling fan will fall, even if it develops a wobble. During a proper installation, ceiling fans are securely bolted to a ceiling joist, and the fasteners used for mounting are generally separate from the components related to balancing. A wobble is typically caused by an imbalance, which can be annoying and may lead to other issues, but is not usually dangerous on its own.

However, if a fan is wobbling because it was not installed correctly, it could be at risk of falling. For safety, it's always a good idea to ensure all mounting screws are tight and to address any wobbling or imbalance issues promptly.

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.
