An automatic door won’t close properly, and nothing on the door looks broken. Sometimes, the weather is the culprit. Georgia summers push your air conditioning hard. The increased air flow changes the air pressure inside your building. A door that worked all winter can start to struggle in June.
Why does summer weather change how your doors work?
Your doors respond to the air around them. Pressure builds on one side of the panel and pushes. Your operator works against that push every cycle. Small pressure shifts create real resistance at the door. The seasonal change from winter to summer brings the largest shifts of the year.
What does your A/C do to building air pressure?
Air conditioning moves large volumes of air through your building. The system pulls air out and drives conditioned air in. That exchange rarely stays perfectly balanced. Most commercial buildings run slightly positive or slightly negative in summer. Your doors feel that imbalance on every open and close.
Why the problem reverses in winter
Winter flips the pattern. You switch the A/C off. The pressure that held your door in check goes away. The same door now swings with too much force. Interior doors begin to slam. A setting that worked in July becomes a problem in December. This change can be more than just annoying. A door closing with too much force or too quickly can become dangerous to people passing through it. Addressing the seasonal changes in door pressure becomes a liability issue.
Why won’t my automatic door close in the summer?
Positive pressure inside your building pushes back on the closing door. Your operator meets resistance it did not face in winter. The door slows down and stops short of the frame. It may not latch at all. Staff prop it open out of frustration. That habit drains your cooled air and weakens security.
What makes interior doors slam when the A/C turns off?
Negative pressure pulls doors shut fast. Without summer’s air load, the closer overpowers the door. The door hits the frame hard. Repeated slamming wears out hinges and closers over months. It also rattles everyone working nearby.
How do you fix an air pressure door problem?
You adjust the door, not the weather. Apollo tunes your operator to match the pressure you have now. We reset the closing force, speed, and backcheck. The door then closes cleanly against summer pressure. Schedule a return visit in the off-season and recalibrate it for winter.
What Apollo checks during an air pressure service call
Our technician watches how your door behaves under load. We measure the closing force against your current building pressure. Then we adjust the operator’s speed and force. A full test cycle confirms the door latches. We never touch your HVAC system. Air balancing is a job for your mechanical contractor. Apollo makes the door work with whatever pressure your building has which can vary doo by door.
Book a seasonal air pressure check
If your automatic door won’t close properly in the summer heat, air pressure may be the reason. Book an air pressure and operator check with Apollo. We adjust the door to match your building, this season and the next. Call 404-590-4599 or request service online.
