If your air conditioner has suddenly stopped cooling, don’t panic! Before calling a professional, there are several steps you can take to diagnose and fix the problem yourself. This comprehensive guide will provide you with everything you need to know about how to fix an air conditioner not cooling.
Check the Power Source
Before diving into more complex troubleshooting, it’s essential to ensure that your air conditioner has power. Check if the circuit breaker has tripped or if the fuse has blown. If the power source is faulty, reset the circuit breaker or replace the fuse.
Inspect the Thermostat
The thermostat is responsible for controlling the temperature of your home. Make sure that the thermostat is set to “cool” mode and that the desired temperature is lower than the current room temperature. If the thermostat is malfunctioning, it may need to be replaced.
Clean the Condenser Unit
The condenser unit is located outside your home and is responsible for releasing heat into the air. Over time, the condenser unit can become clogged with dirt, leaves, and other debris. Clean the condenser unit using a garden hose or a soft brush.
Check the Refrigerant Levels
Refrigerant is the lifeblood of an air conditioner. Low refrigerant levels can result in poor cooling performance. If you suspect that your air conditioner is low on refrigerant, contact a qualified HVAC technician to have it checked and recharged.
Inspect the Air Filter
A dirty air filter can restrict airflow, reducing the efficiency of your air conditioner. Replace the air filter every month or two, especially during the summer months when your air conditioner is running more frequently.
Unclog the Drain Line
The drain line is responsible for draining condensation from the air conditioner. If the drain line is clogged, condensation can build up and cause the air conditioner to malfunction. Clear the drain line using a wet/dry vacuum or a wire hanger.
Reset the Air Conditioner
Sometimes, simply resetting the air conditioner can resolve the issue. Turn off the air conditioner at the circuit breaker or fuse box. Wait for a few minutes, then turn it back on. This will reset the air conditioner and may fix the problem.
When to Call a Professional
If you have tried all of the above steps and your air conditioner is still not cooling, it’s time to call a professional HVAC technician. A qualified technician can diagnose and fix the problem quickly and efficiently.
