How To Cool A Garage In Arizona Florida & Texas


1. Install Garage Attic Insulation To Keep The Heat Out

Garage attic insulation, also known as, garage radiant barrier is important to keep out the heat out of your garage. Arizona, Florida & Texas summers get up to 120 degrees Fahrenheit and working in a garage with no AC can send temperatures rising even higher. Insulating your garage attic is a must if you want to stop the heat from making its way in. Our SRX insulation is perfect garage attics and garage doors. SRX is best garage door insulation for hot climates like Arizona, Florida & Texas.

Installing garage radiant barrier will cost you about $500 for a one car garage and about $800 for a two car garage. In general, it costs about $2 per sqft to install garage attic insulation.

However, insulating your garage will do a great job at keeping out most of the heat, but you are going to need a way to cool your garage as well. That’s where garage air conditioning comes into play. Before we get into that though, let’s talk a little more about insulating your garage door.

2. Install a Garage Mini Split To Cool The Space Down

Garage Mini SplitsYou need garage air conditioning to cool your garage cool in Arizona, Florida & Texas. Most garages in the Phoenix, Arizona Valley weren’t built to have an air conditioning unit or a garage ventilation system. That’s where our energy experts come into play. We have the capability of installing garage mini-split systems, also known as ductless garage ac units, in your garage. Garage air conditioning units only need a single port of ventilation, and can cool down garage areas faster than portable air conditioning units can. With professional garage air conditioner installation, you can turn your garage into a garage workshop.

Garage Mini Split Systems

Installing a mini split system for your garage will help you get the temperature down in the space, and your garage insulation will keep the cool air in longer.

These mini split systems are great for cooling down small spaces like garages and can cool down an average size garage in about 15 minutes. Not even a swamp cooler or portable ac unit can cool a room down that fast.

Installing a garage ac unit is the fastest way to cool down a garage in Florida, Texas & Arizona. Fans blow the heat around. You need something more powerful during the summer to cool down the garage space. Install SRX garage insulation first, then a mini-split to keep the space cool. The mini split won’t even have to run very long because SRX will hold the temperature of the room like a thermos.

Can’t I Just DIY Install A Mini Split System In My Garage?

Yes, with the right tools you can install a mini split system yourself. Although, we strongly urge you not to try to do so. This job involves cutting, electrical work and more. Installing a mini split ac unit is dangerous for the average homeowner and is not an easy task to perform DIY. We suggest hiring a professional ductless ac installer such as ourselves to install your mini-split system for your garage.

3. Install Garage Door Insulation To Keep The Cool Air In

Garage Door InsulationShould i insulate my garage in Arizona, Florida, or Texas? Yes, installing garage door insulation is the most important step for cooling a garage in AZ, FL, and TX. Your garage door is where most of the heat escapes due to no insulation in the door. Insulating your garage door is an important step if you want to keep all of that cool air inside the garage. If you do not insulate your garage well, the air will escape, take longer to cool down your garage and cost you additional money in cooling bills. The utility bill for your home is already high enough, why not save a little money and still keep your entire home cool?

On average, insulating a garage door costs about $300 for a single bay one car garage (single bay), $600 for a two-car garage (double bay), and $900 for a triple car garage (triple bay).

Not only does SRX work for your garage attic and garage door insulation but it also works for your home. Installing SRX in your attic is guaranteed to save you at least 20-50%. Furthermore, if you choose to go with other energy products, you could save up to 100% of electricity. Yes, We said 100% Guaranteed!!!

Can’t I Install Garage Insulation or Garage Door Insulation Myself?

Yes, you can install your garage insulation yourself. Although will you be sure that you are doing it correctly? Do you know where to look for the places the air seeps in the most? Do you also have the capabilities of installing the next part of the job that cools down your garage (mini split system)? If the answer is no to any of those questions, you should hire a professional insulation contractor or radiant barrier contractor such as ourselves that have decades of experience with installing insulation in garages.
