Air conditioning (AC) systems often come equipped with error code displays to help users diagnose problems more easily. Here are some common error codes you might encounter:
-
E1: Indicates an issue with the temperature sensor. This could mean it's faulty or disconnected.
-
E2: Suggests a problem with the indoor unit's coil sensor.
-
E3: Points to an issue with the fan speed. It could be that the fan motor is malfunctioning.
-
E4: Indicates a problem with the outdoor unit's coil sensor.
-
E5: Points to an issue with the room temperature sensor.
-
E6: Suggests a problem with the communication between the indoor and outdoor units. This could be due to wiring issues or a faulty control board.
-
E7: Indicates a refrigerant leakage or a refrigeration cycle issue.
-
E8: Suggests an issue with the high-pressure switch.
-
E9: Indicates a problem with the low-pressure switch.
-
E0: This usually means that the unit is in standby mode or that there's no fault detected.
Keep in mind that error codes can vary depending on the make and model of your AC unit. Always refer to your unit's manual or contact the manufacturer for specific error code meanings and troubleshooting steps.

My old furnace had finally broken down for the last time when contacted twintech to have a new furnace installed They were prompt, knowledgeable and very reasonably priced. They did such a great job i tell all my friends and family about this company.

To whom it may concern, I recently had TwinTech (Greg and Grant Dainty) replace my furnace and service both my gas fireplaces and air conditioning unit. They were professional, courteous and very fair in their pricing. I would gladly recommend TwinTech to anyone needing work done. I can be contacted at 905-626-XXXX.

My Fiancé and I have relied on Twintech Heating and Cooling now for the better part of the last 10 years. In that time, Greg has installed a furnace, an air conditioner, and a heat-pump at our residence in Toronto. In each instance Greg and his team were a pleasure to deal with. They were courteous and professional throughout the whole process and the quality of their work is first rate. Our experiences have always been extremely positive and we have referred his services numerous times to our friends and family. Without hesitation, I would recommend Greg and TwinTech Heating and Cooling to anyone looking to service or replace their existing heat/AC equipment
