Troubleshooting a Non-Cooling AC

Few things are more frustrating than an air conditioner that won’t cool your home. If your AC repair in Oshawa is overdue, several issues could be causing poor performance. The most common culprits include refrigerant leaks, dirty filters, faulty thermostats, or electrical problems. Identifying the issue early can prevent further damage and restore comfort quickly.

Common Causes and Solutions

1. Dirty or Clogged Air Filters

A blocked air filter restricts airflow, reducing cooling efficiency. Replace or clean filters every 1-3 months, especially during peak usage.

2. Low Refrigerant Levels

Refrigerant leaks prevent proper cooling and strain the compressor. A professional technician must locate and repair leaks before recharging the system.

3. Thermostat Malfunctions

If the thermostat isn’t reading temperatures correctly, your AC may not turn on or cool properly. Check batteries and recalibrate if needed.

4. Frozen Evaporator Coils

Poor airflow or refrigerant issues can cause coils to freeze, blocking cooling. Turn off the system and let it thaw before calling for repairs.

5. Electrical Failures

Faulty wiring, tripped breakers, or capacitor problems can prevent the AC from starting. A licensed technician should handle electrical diagnostics.

When to Call a Professional

While some issues (like filter changes) are DIY-friendly, most AC problems require expert attention. If your system blows warm air, makes strange noises, or cycles constantly, schedule air conditioning repair in Oshawa immediately. Delaying repairs can lead to more expensive damage.

Preventing Future Cooling Problems

Regular maintenance, including annual tune-ups and filter changes, keeps your AC running efficiently. Scheduling service before summer ensures your system is ready for peak demand
