Attic Rodent Removal and Proofing Service Orange CountyThe Only Home Comfort with 10 Years HomeDepot Experience in O.C.!
Cooling an attic in the summer can be challenging for several reasons. The most straightforward explanation is that we are working against the prevailing heat outside. So, the higher the mercury rises, the more difficult it can be to keep the inside of a home or office cool.
However, in our experience, attics are uniquely challenging to keep cool. For starters, the attic can become extremely hot due to the sun’s rays beating down on the roof. We know that in some states, an unventilated attic can reach 150 degrees Fahrenheit in the summer, which is 50 degrees higher than it should be. This can cause damage to the roof’s shingles and push the air conditioner to work harder, leading to higher energy bills.
The other challenge is preventing heat transfer from the attic to the living space. High-quality insulation prevents heat from radiating downwards while keeping cool air from escaping through the attic. An improperly vented attic can generate a lot of heat with lots of hot outside air entering the attic.
The good news is that there are various ways to cool an attic, but the bad news is that not all of them are effective. Some recommend using powered attic ventilators (PAVs) to keep their attic cool and reduce air conditioning costs, but this is only effective if done right.
Using a quiet cool smart gable fan is probably the most efficient way of keeping the attic and home in general cool. It is also highly energy efficient compared to having your air conditioning run over time when it starts boiling outside.
In this article, we’ll walk you through how a quiet cool smart gable fan can lower the temperature around the house and how you can get it installed for free!
How Does A Gable Fan Cool Your Home?
If you are thinking, “how to cool down my attic in summer.” Then you probably heard that a gable fan is one of the most effective options. However, to understand why it is an option you should consider, you need to know how it works.
A gable fan is a type of attic fan installed on an attic’s gable walls. The purpose of a gable fan is to ventilate the attic space by drawing hot air out and allowing cooler air to enter. The idea is that reducing the temperature in the attic will consequently reduce the temperature in the rooms below, which can help reduce cooling costs because the air conditioner does not have to work as hard. However, depending on how hot it gets, you may still need to run the air conditioning, so it does not replace it.
The rule of thumb regarding proper attic ventilation is for every 1 square foot of ventilating ability for every 150 square feet of space. A typical gable fan for residential use provides 1 square foot of ventilating space. That is more than enough for most homes.
We usually install a quiet cool smart gable fan for free, which costs over $650. However, this is part of our #1 selling attic upgrade service called Comfy Combo. The ‘smart’ in the fan means it can be controlled via your smartphone. You can turn it on, off, reduce or increase speed. This means you can fine-tune it to precisely what makes you feel comfortable and what the weather calls for. That is unlike loads of cheap gable fans installed in most homes.
Plus, the gable fans move a lot of air, way more than most others. That’s why they can evacuate more hot air in a shorter time than most other types of gable fans…and yes, we’ve tested this!
Gable Fan Misconceptions
Over the years, we’ve heard and read some blatant misconceptions about gable fans. Trust us; we wouldn’t be selling this as our #1 attic upgrade if these fans didn’t do anything or if there were better options. But like all other myths, they need to be debunked by experts like us.
Gable Fans are Not an Effective Solution
Some so-called experts suggest that gable fans may not be the most effective solution for cooling an attic. They suggest there are better ways to spend money, like reducing air leaks in the ceiling, improving insulation, or sealing leaks in the attic ductwork rather than installing a gable fan.
The truth is that a gable fan should be installed even after all the above is done because none of that can actively improve ventilation. That’s why it is part of our attic upgrade since that allows us to upgrade the attic in more ways than one.
Used In Conjunction With Other Ventilation Systems
It is said that gable fans are highly effective when they are used in conjunction with other attic ventilation systems, such as soffit vents and ridge vents. If an attic uses soffit vents at the bottom and gable vents at the top for ventilation, having a gable vent fan drawing air into the attic would not be the best solution since it would tend to create positive pressure in the attic which could reverse the natural airflow that occurs when the heat rises through the soffit vents and out.
Yes, this can be a problem, so the attic and the associated venting system must be carefully designed and planned by professionals like us!
