"First and foremost if i could give Solorios Insulation Services 10 stars i would. The work completed was exceptional. Every step of the job from the beginning bid to the last part of the clean up was better than expected. The work was completed in the time they said it would be and (Jesus) was a stand up guy to have working in our home and paid attention to every detail that meant so much to us. I cannot say enough of how happy i'am with this company. We definitely will be calling them again in the near future i highly recommend them. Thank you!!"

Bathroom Fan Installation FAQs, answered by experts

Your blower motor may make a loud sound if the bearings overheat or wear down as your system ages. You may also hear loud noises coming from your blower if it’s struggling to pull in air due to dirty or damaged ducts, closed or blocked vents, or a dirty air filter. Typically, this causes a loud whistling sound.

If your ceiling fan is humming, that's usually a sign of an electrical issue. A low-pitched grinding sound could be caused by the motor or a lack of lubrication in the bearings, but a true humming sound will be caused by a failing capacitor or faulty wiring. Unless you have experience with electrical issues, you should call a pro for any ceiling humming noises.

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.

You should generally avoid using WD-40 on a ceiling fan. While it might quiet a squeak temporarily, it is primarily an anti-corrosion and water displacement agent, not a true lubricant, and can damage the fan's components over time. Most modern ceiling fans have sealed bearings and do not require oiling, so a squeak may indicate another issue. For fans that do require lubrication, it is better to use a light machine oil, 30-weight motor oil, or a lubricant specifically designed for ceiling fans.

On average, a bathroom fan lasts between five and ten years. The fan's lifespan depends on its quality, installation, and frequency of use. You can extend its life with regular cleaning and by promptly addressing any issues. Common signs that you need a new fan include mold growth, a burning smell, unusually loud noises during operation, or lingering odors in the bathroom. If your fan is no longer working as well as it once did, consider replacing it. The cost to install a new bathroom fan is typically between $240 and $550.
