10 Troubleshooting Tips For Common AC Problems

When the sweltering summer heat is at its peak, there’s nothing more refreshing than stepping into an excellent, air-conditioned space. However, just like any other system, air conditioners can encounter problems from time to time. It can be incredibly frustrating to experience an AC malfunction, especially when you need it the most. But fear not! Niagara Home Heating is here to assist you with our expertise and reliable service.

We are the best HVAC contractor in Niagara Falls, ON, area providing comprehensive AC repair services. Before you call us, here are ten simple troubleshooting tips to help get your air conditioner running again:

  1. Check the Thermostat: Start your troubleshooting process by checking the thermostat settings. Ensure it is set to the desired temperature and mode (cooling). Replace the batteries if necessary, and ensure the thermostat is clean and debris-free.

  2. Inspect and Change the Air Filter: A clogged air filter can restrict airflow, reducing the efficiency of your AC system and potentially causing it to malfunction. Regularly inspect and replace the air filter every 1-3 months or as the manufacturer recommends.

  3. Inspect the circuit breaker: If your AC isn’t turning on at all, check the circuit breaker. Sometimes, a tripped breaker can disrupt the power supply to the unit. Resetting it may solve the issue.


  4. Clear debris from the outdoor unit: Leaves, dirt, and other debris can accumulate around the outdoor unit, obstructing airflow. Ensure the area around the unit is clear to maintain proper ventilation.


  5. Examine the condensate drain line: A clogged drain line can lead to water leaks or an overflowing drain pan. Clean the line regularly to prevent such issues and ensure the smooth functioning of your AC.


  6. Inspect the evaporator coils: Dirty or frozen evaporator coils can impair cooling efficiency. Gently clean the coils with a soft brush to remove any accumulated dirt or ice


  7. Verify the fan operation: Check if the fan blades are spinning correctly. If not, there might be an issue with the motor or fan belt. Contact a professional technician for assistance.


  8. Examine the ductwork for leaks: Leaky ducts can waste energy and reduce the effectiveness of your AC system. Inspect the ductwork for any visible leaks or disconnected sections. Seal them to improve efficiency.


  9. Ensure proper insulation: Inadequate insulation can cause cool air to escape and hot air to enter your living space. Properly insulate windows, doors, and walls to maintain a comfortable indoor environment.


  10. Schedule regular professional maintenance: By scheduling regular maintenance with Niagara Home Heating, our expert technicians can identify and address potential issues before they escalate.
