When Do AC Error Codes Show Up?
Posted On: June 17, 2024
AC error codes typically show up under the following conditions:
-
System Malfunction: When there is a malfunction in any part of the AC system, such as the compressor, fan motor, or thermostat.
-
Sensor Issues: If any of the sensors that monitor temperature, humidity, or pressure are faulty or malfunctioning, error codes will be displayed.
-
Electrical Problems: Issues with electrical components or wiring, such as short circuits, power surges, or voltage drops, can trigger error codes.
-
Maintenance Alerts: Some AC units are programmed to show error codes when routine maintenance is required, such as cleaning or replacing filters.
-
Blocked Airflow: If there is an obstruction in the airflow, such as clogged filters or blocked vents, the system may display an error code.
-
Refrigerant Issues: Low or high refrigerant levels can cause the AC to display error codes, indicating a need for refrigerant recharging or checking for leaks.
-
Communication Errors: In systems with multiple components (e.g., split systems), if there is a communication failure between the indoor and outdoor units, an error code may be displayed.
These error codes help diagnose and troubleshoot the issues, allowing for timely repairs and maintenance to ensure the AC system operates efficiently. The exact nature of the error code and its meaning will depend on the make and model of the air conditioning unit.

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!

Amazing experience with TwinTech Heating & Cooling! Their team was professional, knowledgeable, and efficient from start to finish. They installed my new furnace quickly and left everything spotless. 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. IÂ’ve used the company in the past for my furnace so I was happy when I recognized Greg at my front door. HeÂ’s great and the service is always top notch. IÂ’d 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!!

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!

Just had a new furnace installed by Twintech. I canÂ’t express how great these guys are at what they do. From the sales to installation they were professional all the way. Very reasonable pricing and courteous during the installation and willing to answer any questions I had. Highly recommended !!!
