Air Conditioner is Not Turning On
Posted On: April 7, 2024
If your air conditioner is not turning on, there could be several reasons for this issue.
Here are some steps you can take to troubleshoot the problem:
If your air conditioner is not turning on, there could be several reasons for this issue. Here are some steps you can take to troubleshoot the problem:
-
Check the power source: Ensure that the air conditioner is properly plugged into the power outlet and that the outlet is receiving power. You can try plugging in another device to verify if the outlet is working correctly.
-
Inspect the circuit breaker: Check the circuit breaker or fuse box to see if the circuit that powers the air conditioner has tripped or blown a fuse. If it has, reset the breaker or replace the fuse and try turning on the air conditioner again.
-
Thermostat settings: Make sure that the thermostat is set to a temperature lower than the current room temperature and is set to the "cooling" mode. Sometimes, incorrect thermostat settings can prevent the air conditioner from turning on.
-
Check the air filter: A dirty or clogged air filter can restrict airflow and cause the air conditioner to malfunction. Check the air filter and clean or replace it if necessary.
-
Inspect the condensate drain: If the condensate drain is clogged, it can cause the air conditioner to shut off. Clear any obstructions in the drain to ensure proper drainage.
-
Inspect the outdoor unit: Check the outdoor unit for any debris, such as leaves, dirt, or branches, that may be blocking airflow. Clear away any obstructions and ensure that the unit is not covered or obstructed in any way.
-
Check for signs of damage: Inspect the air conditioner for any signs of damage, such as frayed wires or damaged components. If you notice any damage, it's best to call a professional HVAC technician to assess and repair the issue.
-
Reset the system: Sometimes, simply turning off the power to the air conditioner for a few minutes and then turning it back on can reset the system and resolve the issue.
If none of these steps resolve the problem, it's possible that there is a more serious issue with the air conditioner that requires professional repair. In such cases, it's best to contact a licensed HVAC technician to diagnose and fix the problem.

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.

Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!

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 did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!

The technicians took the time to explain everything and made sure I was comfortable with the system before they left. Great customer service and fair pricing. I highly recommend them for anyone needing HVAC services!

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

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!!
