How To Know When To Replace Your Whole House Fan

When to replace whole house fan

A whole house fan can be a wonderful way to cool a home without using so much air conditioning but it can also be some people's worst nightmare.

Reports of noisy, loud fans that sound like a broken helicopter are common. Yet, this is often because the house has an old whole house fan installed or for other reasons such as a bad installation.

If you're at the point whether you're not sure if you should replace your whole house fan or remove it entirely, our professionals at Comfort Cool Fans can offer a little information to help.

Fortunately, if replacing your whole house fan is an option you'd want to consider over removing it entirely, you may just need to replace the fan motor rather than the entire system.

Your Whole House Fan Is Noisy

Older models of whole house fans are noisier than new models. If your fan is driving you crazy, replacing it with a new model will solve the problem. Plus, with a good quality brand, you'll enjoy more energy efficiency and durability. It's up to you whether you prefer to remove it or replace it, but know that the newer models like our QA-Deluxe and CentricAir Fan are ultra-quiet.

A bad installation can cause an entirely good, new model to make noise. In this case, you can probably get another installer to help you out if too much time has passed and you can't or don't want to keep working with the original installer.

Rattling and banging most likely means the fan blades are banging against the housing as they turn. It sounds like a helicopter with bad blades is sitting on your roof. This will mean it's time to replace it or remove it because it's not a motor problem.

Your Whole House Fan Is Nearing 10-15 Years Old

Depending on the model you own, your whole house fan will be warranted for around 5 to 15 years. Keep in mind the warranty is limited, offering coverage for parts and material failure due to manufacturer defects, not if the fan just stops working for any reason.

The most obvious sign your fan is getting old is usually noise. If the motor is still working, the weaker fan blades go first, often knocking around as they turn.

If your fan is getting louder and louder, it's probably time to replace it or remove it entirely because it isn't working properly anyway.
