Armstrong air conditioners are tough and reliable. With regular maintenance and service, your Armstrong air conditioner should last you a long time. But if you start to run into technical problems with your unit, you don’t necessarily need to call your service representative right away. Below is a troubleshooting guide that can help you pinpoint or fix the problem yourself. However, always remember, if you’re not confident you can safely execute any of the procedures, your HVAC repair technician will be happy to help!


Tip #1: Before going into specific fixes, it’s best to make sure your unit is getting the power it’s supposed to. Make sure it didn’t get accidentally unplugged, and if it still has no power, check your fuse box/circuit breakers.


Tip #2: Not getting cool air. If this is your issue and your furnace is receiving power, first check to make sure your thermostat is set to COOL. Otherwise check the filters to make sure they aren’t blocked with dust or dirt. Filters should be changed or at least checked around once a month.


Tip #3: No airflow. Again, check to make sure your filters aren’t blocked. Another thing to check for is a dirty or frozen coil. To do so, check the indoor unit for any water underneath it. If there’s none, feel around the coil enclosure. If it feels cool, turn off the AC for 1-3 hours to see if it defrosts. If the problem persists, contact your HVAC tech.


Tip #4: Overflowing drain pan. If this is the problem, then there’s a problem with the overflow switch. The best thing to do is to contact your HVAC tech to take care of the problem.


Tip #5: The air conditioner never shuts off. This could be due to the thermostat being set too high. The best thing to do is to adjust the thermostat depending on the weather so that the system isn’t overworking.

Professional, courteous and efficient, don’t need to say more than that! Use them you will not regret it.

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 !
