PRN Roofing, the best local roofer in Tuscaloosa, is always on the lookout for new innovations in roofing. While a whole-house fan is nothing new (fans themselves have been around for centuries and the idea of cooling your home by drawing in the outside air has been around since electricity was invented), using a whole-house fan with air conditioning has recently become popular. In this blog post, we’ll take a look at whether or not you should install a whole-house fan. Contact us today for a free roofing estimate!


  • Save money. A whole-house fan works by drawing in the outside (cooler) air into your home that is hotter. For the most part, you can use a whole-house fan for most of your cooling needs and save your air conditioning for the hottest days. Even then, you can use your whole-house fan in the morning and then turn on your air conditioner during the hottest part of the day. The whole-house fan will draw heat out, leaving your air conditioner to do less work than it normally would have had to do. This saves you money on electricity and in repair costs when your air conditioning unit decides to give up the ghost.
  • Continually have fresh air to breathe. A whole-house fan constantly replaces the air inside your home. Having clean air to breathe instead of stale air helps to reduce the airborne particles, pathogens, or chemicals that are in the air that you could be breathing in. Radon, formaldehyde, carbon monoxide, cooking smells, and pet odors also hang in stale air. While these aren’t necessarily bad for you, then can irritate your allergies and cause other respiratory conditions to flare. On the flip side, a whole-house fan can bring in these airborne allergens as well. It’s definitely a delicate balance that you will have to find if this is a concern of yours.
  • Fast. A whole-house fan works extremely fast, cooling your home in minutes if the outside air is cooler than the inside. PRN Roofing in Tuscaloosa recommends that the outside air temperature be at least five degrees cooler than the indoor air temperature and 10 degrees or more is ideal.
  • Can replace your entire air conditioning unit. If you live in a temperate climate, a whole-house attic fan can replace your air conditioning completely, leaving you with hundreds of extra dollars in saved utility expenses.
  • Extends the life of your roof. By flushing out the hot air from your attic, you are lowering the temperature of your home and your roof. Excess heat can damage your roof’s shingles, causing the need for either a roof repair or a roof replacement service by PRN Roofing.
    Rids your roof of excess moisture. Moisture attracts trouble. It allows mold and mildew to grow and attracts insects and critters you don’t want in or near your roof. By flushing out hot air, you’ll also cause evaporation to happen, getting rid of any excess moisture in your roof as well.


The key with the whole house fan is to not use it at the same time as your air conditioning unit because your whole house fan will draw out the cooled air. For best results, PRN Roofing, your local roofer in Tuscaloosa, recommends that you use both for your air conditioning needs. Use your whole-house fan as much as possible and then switch over to your air conditioning unit only on the hottest of days. If you are still in doubt, give us a call. We can help you decide if a whole-house fan or an attic fan would best suit your individual needs.


Unless you feel extremely confident in your abilities to cut a hole in your roof and install an attic fan, you should leave the installation to a professional roofer, such as PRN Roofing. You’ll need adequate vents installed in the right places in addition to the attic fan itself. Your roof is just too important to the health of your home to attempt a project you really have no expertise in. You could end up turning your simple and easy whole-house fan installation project into a major roof repair instead.
