Attic fans can be a game-changer for homeowners in the Tampa Bay area. With the sun relentlessly beating down on our homes for the better part of the year, our attics can become ovens, driving up indoor temperatures and pushing our cooling systems to the limit. An attic fan can help dissipate this heat, reducing the strain on air conditioners and potentially slashing energy bills. If you’re considering installing an attic fan, Positricity, one of Tampa Bay’s leading electrical companies, has five essential considerations to keep in mind.

1. Type of Attic Fan

Before diving into the installation process, it’s crucial to decide on the type of attic fan you need:

     1. Solar-Powered Fans

These utilize solar panels to operate. They’re energy-efficient, can lower electricity bills, and are particularly suitable for sunny Tampa Bay. However, their efficiency can drop on cloudy days.

     2. Electric-Powered Fans

These are the most common type and are connected to your home’s electrical system. While they are consistently effective regardless of the weather, they do consume electricity, which can affect your bill.

     3. Wind-Powered Fans

These rely on the wind to operate. They’re not as common as the other two types and are dependent on wind speed for efficiency.

     4. Florida’s Insurance Standards Compliance

The Sunshine State has strict homeowner insurance criteria related to electrical safety. With Positricity’s expert installation of Alumiconn connectors, homeowners are well-equipped to meet these exacting standards, thereby maximising their chances of policy approval.

2. Size and Capacity

It’s not a one-size-fits-all situation. The size and capacity of the fan should correlate with the size of your attic. Typically, you’ll need a fan that can move about 700-1200 cubic feet of air per minute for every 1,000 square feet of attic space. A too-small fan won’t effectively ventilate the attic, while an oversized fan can cause unnecessary energy consumption.

3. Thermostat and Humidistat Control

Modern attic fans come with built-in thermostats that automatically turn the fan on or off based on the attic temperature. This is a valuable feature that ensures your fan only runs when necessary, thereby saving energy.

Additionally, in humid areas like Tampa Bay, you might consider a fan with a humidistat. This feature detects moisture levels, and when they’re too high, it activates the fan to prevent mold growth and other moisture-related issues.

4. Proper Installation and Sealing

A poorly installed attic fan can end up being more of a liability than a benefit. Improper sealing can allow rainwater to seep into the attic or lead to drafts that negatively impact home insulation. At Positricity, we emphasize the importance of professional installation. A trained electrician ensures that the fan is securely mounted, all gaps are sealed, and electrical connections are safe.

5. Maintenance and Safety Checks

Once installed, an attic fan isn’t something you can set and forget. Regular checks are necessary to ensure that it’s functioning properly and safely. This includes:

     1. Blade Checks

Over time, fan blades can become dirty or bent. Regularly inspect them to ensure they’re clean and in good shape.

     2. Motor Checks

Ensure the motor isn’t overheating or making unusual noises. If it is, it might be time for a replacement.

     3. Electrical Inspections

This is where a company like Positricity comes into play. Periodic electrical checks can spot any potential issues before they escalate into more significant problems. Remember, combining moving parts with electricity always demands respect and caution.


While an attic fan can significantly improve the comfort and energy efficiency of your Tampa Bay home, it’s essential to make informed choices during the installation process. From selecting the right type and size of the fan to ensuring its proper maintenance, every step matters.
