AC Emergency? Here's What to Do Before the Tech Arrives

Your AC just died and the technician is on the way. It is 91 degrees outside and climbing inside. What you do in the next hour matters — for your family's comfort, for your safety, and possibly for the condition of your HVAC equipment when the tech walks through the door.

This is not a guide to fixing the AC yourself. That is not the goal here. This is a guide to making smart decisions during a real emergency while a professional is en route, written specifically for Birmingham homeowners who know firsthand how fast a house can become dangerous in an Alabama summer.

Immediate Priority: Protect People First

Before you worry about anything with the HVAC system, take stock of who is in the house. Elderly adults, infants and young children, pregnant women, and anyone with heart conditions, respiratory conditions, or heat-sensitive medications are at significantly elevated risk in heat emergencies. These people should not stay in a home without cooling when outdoor temperatures exceed 90 degrees.

If you have vulnerable family members, make arrangements immediately:

• A neighbor's air-conditioned home
• A local library or community center
• A grocery store or shopping center
• A hotel with immediate availability

Heat stroke can develop faster than most people realize — particularly in elderly adults who may not feel thirst even when significantly dehydrated.

For healthy adults, the risk threshold is higher, but it is still real. Indoor temperatures above 95 degrees are dangerous for anyone. By that point, you should be taking active cooling measures or leaving the home.

Lower the Indoor Temperature as Fast as Possible

Every degree of indoor temperature gain you prevent now is energy your body does not have to spend staying cool. Here is how to slow the temperature rise effectively.

1. Close every blind, curtain, and drape in the house immediately — solar heat gain through windows is the primary driver of temperature increase
2. Close interior doors to rooms you are not using — concentrate in the smallest, most central area
3. Run every ceiling fan on highest setting in counterclockwise mode (summer cooling direction)
4. Position portable fans for cross-ventilation if outdoor temp is lower than indoor temp
5. Move to the lowest level of the home — heat rises, making ground floors naturally cooler

What Not to Run While Waiting

Several common household appliances generate substantial heat and should be avoided during an AC outage:

• The oven and stove — the most obvious heat generators
• The clothes dryer — generates enormous heat and humidity
• The dishwasher — produces heat and steam
• Desktop computers and gaming consoles — meaningful heat in an enclosed space
• Large-screen televisions — produce more heat than you might expect

Minimize electronics use and stick to phones and tablets, which generate very little heat. Use a microwave if you must heat food, and stick to cold meals or delivery if possible.

Active Cooling for Your Body

Air movement is the key. A spray bottle filled with water applied to your skin — especially pulse points on the wrists, neck, and temples — combined with fan airflow is genuinely effective body cooling. Cool, damp cloths on the same pulse points provide direct heat exchange.

Stay hydrated. In hot conditions, you lose fluid faster than you feel thirsty, especially at rest. Drink water consistently, not just when you feel thirsty. Avoid alcohol and excessive caffeine, which accelerate dehydration.

Helpful Things to Tell the Technician When They Arrive

Good information speeds up diagnosis significantly. When the technician arrives, be ready to share:

1. When did the system last work normally? Not just today — when did it last cool properly?
2. Did you hear anything unusual before it stopped? Clicks, buzzes, grinding, or unusual fan sounds?
3. Have you done anything to the system recently? Changed the filter, adjusted programming, reset a breaker?
4. How old is the system? The model and serial number on the outdoor unit data plate helps determine age
5. Has the system had any recent repairs or recurring problems?

The technician is your partner in this — the more they know upfront, the better they can help you.
