Is My Air Conditioner Working?
Posted On: June 11, 2024
To determine if your air conditioner is working properly, you can follow these steps:
1. Check the Thermostat:
- Ensure that the thermostat is set to "cool" mode.
- Make sure the temperature setting is lower than the current room temperature.
- Check if the thermostat display is functioning and shows the correct settings.
2. Inspect the Airflow:
- Check the vents for proper airflow. If the air is not cool or the airflow is weak, there may be an issue.
- Make sure the vents are not obstructed by furniture or other objects.
3. Examine the Air Filter:
- A dirty or clogged air filter can impede airflow and reduce cooling efficiency. Replace the filter if it’s dirty.
4. Listen for the AC Unit:
- Go outside and listen to the outdoor unit (compressor). It should be running smoothly without any unusual noises.
- Inside, the fan should be running, and you should hear a consistent hum from the unit.
5. Check for Ice or Water:
- Look for ice buildup on the refrigerant lines or the evaporator coil inside the unit. Ice formation can indicate a problem with the refrigerant levels or airflow.
- Check for water leakage around the indoor unit, which might indicate a clogged drain line.
6. Feel the Air from the Unit:
- If the air coming from the vents is not cool, there might be an issue with the refrigerant or the compressor.
7. Check the Circuit Breaker:
- Ensure that the circuit breaker for the air conditioner is not tripped. Reset it if necessary.
8. Inspect for Error Codes:
- Some modern thermostats or AC units display error codes when there’s an issue. Refer to the user manual for troubleshooting based on these codes.
9. Energy Bills:
- A sudden increase in your energy bill can be a sign that your AC is working harder than it should, indicating a potential issue.
When to Call a Professional:
If you’ve checked all these items and your air conditioner still isn’t working properly, it’s time to call a professional HVAC technician. They can diagnose and fix issues related to refrigerant levels, electrical components, and other complex problems.

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!

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!!
