Comfortmaker air conditioners are built to last, and even come with an impressive warranty. But don’t go rushing to replace your furnace if it breaks. If it’s less than 10 years old and still under warranty then it can easily be repaired. So if your Comfortmaker air conditioning isn’t cooling, try these troubleshooting tips before you go calling your HVAC repair company.


First, make sure power is getting to the unit properly and that the thermostat is set to cool. If the unit is on and plugged in but not getting power, check your circuit breaker. If the unit is on and set to cool but isn’t cooling the way you want, try lowering the temperature by a few more degrees. Next, make sure the air filters have been cleaned or replaced to ensure unrestricted airflow.


Next, inspect the fan. If it’s not running or is noisy or overheating, the issue may be with the dual run capacitor. Check the manual to see where it’s located and make sure it’s not bulging or leaking. If it is, replace it. If that doesn’t help, you can use a multimeter to inspect the voltage going to the motor. If it’s receiving the correct voltage but still isn’t working, you likely have to replace the motor.


Lastly, if the unit still isn’t cooling, check the compressor. This is the part responsible for circulating the refrigerant needed to cool the air through the AC system. If you suspect the compressor is the reason for the issue, use a multimeter to check for continuity. If the circuit is open, then this may be the problem and your HVAC technician will be able to replace it for you!

TwinTech was a pleasure to deal with from the estimate through installation. We replaced a 28 year old a/c unit with one recommended by TwinTech's sales representative Dave who took the time to go over the product with us and answer any questions. The warranty is for 10 years parts and labour and they will complete the registration for you. Installation was by Greg (owner) and Mitch and Spencer who were quick and efficient and left everything clean and tidy.

Very professional, from the sales consultation and inspection to the final installation. Met every expectations we had for the job. A local business with great client support. We highly recommend. Twintech is a blue chip! Thanks!

by Private User on Twintech Heating and Cooling

I left a live chat message on their website that my air conditioning was not working. Within 1hr a representative called me to discuss my options.
The next day he came to the house to review my needs and give me a price for a new system. Price quoted was less than I expected and the installation was completed the following day. I found their salesman and the installers very knowledgeable and easy to deal with. All my questions were answered. Everything was properly explained in regards to what unit was needed and why, along with instruction where needed for use.
The installers made sure everything was working properly before they left.

This is to thank Twintech Heating and Cooling for their exceptional and timely service. Mitch, their technician was very courteous and generous with his time right from his first meeting with us. He not only took the time to check everything but also educated us on why we needed what he recommended. Greg and Mitch graciously accommodated us on our requested day and time for job to be done. They were both very courteous and responsive to our needs and special requests especially in a tight spot. The job was finished neatly and on time. Thank you Twintech for your great service !
