Attic Ventilation in Florida

When the Florida sun starts beating down on your home, your attic heats up fast. And when the air inside is trapped, the heat has only one place to go—down into your living space. Once it’s infiltrated the main area of your home, it’s up to your air conditioner to help bring the temperature down again. When you consider just how hot it can get in your attic during the Florida summer (attic spaces alone can exceed 180 degrees F), it’s no wonder that your energy bills may seem out of control.

At Geiger Mechanical, we’re dedicated to helping you keep your home comfortable all year and helping you maintain control of your energy costs. That’s why we recommended installing passive attic vents in your roof line which use no power.

What Attic Vents Do

Heat enters your attic right through the roof. The hot summer sun beats down on your shingles, heating them up. This heat has to go somewhere, so it moves down through the shingles and into the plywood of your roof deck. You may think that insulation you’ve placed below the deck will stop any further heat transfer, but unfortunately, this just isn’t true. The heated surfaces will just transfer the heat to the insulation itself, plus the walls, beams, and any other surfaces they touch. This in turn heats up the air in your attic, and drives that heat down to places to escape. Remember, the rule of heat conductivity is that heat will always look for a cooler place to go. While heat rises, it’s still making its way into your cooler living spaces at the same time.

The air inside your attic can reach temperatures upwards of 180 degrees—far hotter than it actually gets outdoors. Vents allow the Florida heat to escape by both letting it rise and ensuring that it doesn’t remain trapped in your living space. This lowers the heat load in your attic and the air pressure at the same time. The result is a more comfortable home, and an air conditioning unit that doesn’t have to work as hard. In turn, you also get lower energy bills because the passive vents have no moving parts and require no energy to work. Vents allow your AC to run more efficiently, which translates into lower energy costs.

At Geiger Mechanical, we’re concerned with keeping your whole home cool in the most efficient ways possible. Let us help ensure a cooler summer by starting in the warmest part of your home. Call us to install attic ventilation today. Even if you think your attic is already ventilated, research shows that most houses do not have sufficient or properly placed attic ventilation, leading to higher energy costs and overworked AC units. Call us today and make an appointment to speak to a trained technician about adding more ventilation to your attic, so that you can keep cool this summer.
