Air Conditioner Repair Tips For Ottawa Homeowners

During the height of summer in Ottawa, there’s nothing more frustrating than an air conditioner that suddenly stops working, especially when high heat and overwhelming humidity are present. At AirZone HVAC Services, we specialize in diagnosing and rectifying any issues with your cooling system, from minor fixes to significant repairs such as compressor replacements. Before you pick up the phone, however, there are a few do-it-yourself tips you can try to resolve common air conditioner problems.

Self-Help Tips for Air Conditioner Troubleshooting

  1. Inspect Your Furnace Filter: A clogged filter can block air from passing through the evaporator coil, leading to freezes, water overflow, and potentially severe damage to your system.
  2. Check the Electrical Panel: Overuse on hot days can trip breakers. If your air conditioner stops, ensure the breaker hasn’t been flipped to prevent power from reaching your unit.
  3. Outdoor Disconnect Switch: This is essentially your outdoor unit’s power switch. Ensure it hasn’t been mistakenly turned off.
  4. Condenser Maintenance: Verify that your outdoor condenser is clear of any debris or obstructions to maintain proper airflow.
  5. Drainage Check: Ensure the drainage tube or PVC pipe connected to your indoor unit isn’t clogged. This common issue can lead to water damage if not addressed.
  6. Thermostat Settings: Make sure your thermostat is set to cooling mode and that the temperature setting is lower than your home’s current temperature.
  7. Furnace Switch: A surprisingly common issue is the furnace switch being turned off, which halts distribution of cool air throughout your home.
