How to Know When It’s Time to Replace an Old Whole House Fan

Whole house fans have been around for decades, but as the air conditioner became more commonplace in American homes, whole house fans became more scarce. However, in more recent years, as the masses have become more aware of their carbon footprint and indoor air pollution, the whole house fan has made a comeback. Plus, opening some windows and turning on your whole house fan is a cheaper option than running your air conditioning.

That being said, if you have an old whole house fan, it might not be up to standard, and could be inefficient, costing you more than a newer, updated model might. In this article, we will explore how to identify when to replace an old whole house fan.

When to Replace Your Whole House Fan

Your Whole House Fan is 10-15 Years Old
Most whole house fans are warranted for somewhere between 5 and 15 years. These warranties are usually limited and cover parts and material failures due to manufacturer defects. So if your fan just stops working, not because of a particular part breaking or failing, your warranty may not cover it. As whole house fans age, the motor might start slowing, and the fan blades can start to go, causing them to knock around. This means that the fan will be less effective and may cause more noise.

The easiest way to spot if you should replace your whole house fan is if it is getting very noisy. If your whole house fan is rattling loudly, it could be a problem with the motor. Plus, even if your old whole house fan is in good shape, it may still be too loud. Older models are generally much noisier than newer models. So if the noise from your whole house fan is bothering you at all, it may be time to replace it.

Replacing older models with newer whole house fans will boost your home's efficiency. Newer models are much more energy-efficient than older ones, meaning you will spend less money on your energy bill, and your home will become more environmentally friendly. At the same time, newer models may be more fitted to your home, cooling down and cycling air through your home faster while also using less energy.

Plus, newer models are now designed with noise in mind. Therefore, many new models are designed to be quiet so that they can run in the background without bothering you.
