Imagine stepping into your Phoenix garage during the scorching summer, and the air hits you like a blast furnace. It’s not just uncomfortable; it’s an oppressive wave of heat that radiates into your home, compromises stored items, and makes any quick task unbearable. Your garage becomes a superheated box, often reaching temperatures well over 120°F (49°C), especially when outside temperatures regularly push past 110°F. This isn’t merely an inconvenience; it’s a critical point of heat transfer that burdens your entire household, forcing your AC to work harder and driving up energy bills. The good news is, much of this extreme heat can be mitigated with effective garage door ventilation strategies.
