So My Air Conditioner Stopped Working, What Now?

If your air conditioner has stopped working, it can be frustrating, especially during a hot day. Here’s a step-by-step guide on what to do next:


1. Check the Thermostat

  • Ensure that your thermostat is set to "cool" and that the temperature setting is lower than the current room temperature.
  • Replace the batteries if necessary, or try resetting the thermostat.

2. Inspect the Circuit Breaker

  • Check your home's electrical panel for any tripped circuit breakers. If you find one, reset it and see if the AC starts working.

3. Examine the Air Filter

  • A clogged air filter can restrict airflow, causing the system to shut down. Check and replace the air filter if it’s dirty.

4. Look at the Outdoor Unit

  • Ensure that the outdoor unit (condenser) is free of debris like leaves or dirt. Clean around the unit to maintain proper airflow.

5. Check for Ice Build-Up

  • If you notice ice on the outdoor unit or the refrigerant lines, turn off the AC and let it thaw. Ice build-up often indicates a problem with airflow or refrigerant levels.

6. Inspect the Drain Line

  • A clogged condensate drain line can cause the AC to stop working. If the drain line is clogged, it may need to be cleaned to allow proper drainage.

7. Listen for Unusual Noises

  • If the AC unit is making strange noises, it could indicate a mechanical issue, such as a loose part or a failing compressor.

8. Contact a Professional

  • If you’ve checked the basics and the AC still isn’t working, it’s time to call a professional HVAC technician. They can diagnose and repair more complex issues, such as refrigerant leaks, compressor failures, or electrical problems.

For residents in Pickering or the surrounding Durham region, it’s essential to contact a reliable local HVAC service like TwinTech Heating and Cooling. They offer expert AC repair and maintenance services to get your system back up and running efficiently.

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all!

I definitely recommend TwinTech!

I returned from vacation to find my AC unit on the Fritz. After calling way too many places I connected with TwinTech. I’ve used the company in the past for my furnace so I was happy when I recognized Greg at my front door. He’s great and the service is always top notch. I’d highly recommend using twintech for honest, superior service in the Durham region. Thanks!

by Nicole Alain on Twintech Heating and Cooling

I called Twin Tech when my air conditioning stopped working. Greg came over to diagnose the issue - the same day. He was able to diagnose the issue and resolve it quite quickly. Although it was a quick fix, Greg was very thorough in explaining the issue and provided great advice. Not to mention, I felt very comfortable having Greg in my home - which I consider very important when hiring a service provider. Twin Tech will be my go-to from now on. Thank you!!

Twintech Heating & Cooling installed my furnace in 2022 and in fall of 2023 installed my Panasonic Heat Pump. Greg and Mitch did a great job. Helped me through the rebate process. Super happy with the Heat Pump. Only used my furnace 5 times this winter. Energy bills lower, carbon emissions lower.Thank you Twintech. I recommend highly!
