How Do I Know My Whole House Fan Isn’t Working Right?

A whole house fan is a great addition to your home because it can help to improve indoor air quality and even lighten the load on your HVAC system. But even the best whole house fans experience problems from time to time. The trick is identifying these problems early and getting them fixed before your whole house fan breaks down and stops working completely.

We can complete an inspection and let you know if anything is wrong with your whole house fan that needs to be fixed. If it’s getting close to time for a replacement, we can talk to you about your options for upgrading to a newer whole house fan model. In the meantime, you can keep reading to learn more about the signs that your whole house fan may not be working the way it should.

Fan Age

The top factor to consider when you think your fan is not working right is the overall age. Whole house fans usually last for 10 to 15 years. So if your fan is within that age range, it may be nearing the end of its life. Noticing changes in operation with an older whole house fan can mean that it is time to consider a replacement. It’s completely normal for these fans to slow down and not work as well toward the end of their lifespan as they are wearing out. Sometimes we can make repairs to address the problems. 

Loud Noises

Hearing loud noises come from your whole house fan is a red flag that the fan is not working correctly. Most of the time loud noises come from weak fan blades that are bowing or bending so that they knock against other components during operation. 

Loud noises are never a normal part of the whole house fan operation and need to be addressed immediately. If possible, turn off your whole house fan when you hear a loud noise to prevent any additional damage from continued use. Our team may be able to repair the weak blades and put them back in place so you don’t have to replace your entire unit.

Changes in Indoor Air Quality

If your fan is not working the way it should, you may notice a difference in your indoor air quality. A whole house fan is helping your home by bringing in fresh air from the outside and circulating it to remove stale indoor air. If the air begins to feel heavy, it may be because your whole house fan is no longer filtering in clean air. 

If you don’t notice a difference in how the air feels, you may begin to experience allergy or illness symptoms. Stale air inside of your home can be up to five times more polluted than the outdoor air, increasing the likelihood that you suffer from allergies or get sick. It’s a good idea to have your whole house fan checked out if you suspect that anything is wrong with it.

Shutters Stuck

Your whole house fan has shutters that open and close based on operating cycles. This helps to ensure proper airflow when your fan is blowing and prevents backdraft when your fan is turned off. It’s possible that these shutters are stuck in either the open or closed position. It’s especially concerning when your shutters are stuck closed because your whole house fan cannot operate to circulate airflow properly.
