Don’t let AC problems ruin your summer. At Superstition Cooling, we provide fast assessments and quotes for malfunctioning ACs all season long. One of the most common problems we encounter is an AC not blowing cold air. If your AC is running but not cooling and the temperature is steadily increasing in your home, don’t wait. Read this quick guide of steps you can take to get your AC running again.

Possible Causes

There are many different possible answers to the question, “Why is my AC not working?” While you can cross some off the list with a quick check, we recommend calling in a trained HVAC technician to get everything back in working order.

- Your thermostat isn’t working properly: It might be as simple as your thermostat turning off or having a dead battery. Power flickers can also turn off your thermostat or reset the temperature settings to ‘ventilation’ mode.
- You don’t have enough refrigerant: The cooling power of ACs relies on refrigerant. This fluid absorbs heat and expels it outside your home. But if refrigerant levels get too low because of a leak, it can’t cool the air.
- There are leaking air ducts: Your AC might be providing cool air, but it’s getting lost in the air ducts. A technician can check for variations in air pressure or rips and holes in the ducts.
- Internal components are dirty or frozen over: Every AC requires maintenance, such as keeping the evaporator coils clean and replacing the air filter. Without regular maintenance, dust and debris will build up, and the unit won’t work properly. Dirty coils can even freeze over, straining the system.

Troubleshooting Steps

Because there are so many potential causes of your AC not blowing cold air, you need a systematic approach to determine which is the right fit.

- Ensure your thermostat is on, set at the right temperature and mode, and has no error codes.
- Inspect the coils for ice or debris. We recommend calling a technician to service the AC if you see dust, buildup, or ice crystals.
- Replace the air filter. AC air filters should be replaced at a minimum once a quarter. But it’s generally best to replace them once a month, especially if you live in an area with allergens or you have a pet.
- Call in a trained AC technician. Refrigerant leaks, mechanical issues, and general wear and tear on your unit can all contribute to an AC running but not cooling. The sooner you call in a repair technician, the sooner you can enjoy relief from the heat, and the less likely the issue will become a major repair problem.

How to Prevent

Most air conditioning problems—including having a thermostat set to cool but the AC not turning on or cooling effectively—start as small problems. Preventive maintenance and regular, seasonal tune-ups can keep your air conditioning running in better shape with fewer malfunctions and costly repairs over time. We recommend changing your air filters regularly, inspecting your unit and ducts for problems, and hiring a service for annual or twice-annual servicing.
