Durham Region Air Conditioning Repair, Service and Installation
Armstrong furnaces are tough and can get you through the coldest winters. But if you don’t take care of it properly, you may find yourself with higher than normal utility bills and lots of HVAC bills. Luckily there are some things you can do to increase the life and strength of your furnace.
The easiest and most important is to change the filter about every month. This will keep airflow strong through your HVAC system, prevent other parts of the furnace from getting clogged and it will keep the air in your home free of allergens and dust. To change the filter on your Armstrong furnace, first locate the filter access panel and slide it open or remove it. Then look inside and locate the filter. Remove the old filter by sliding it out of the positioning rails. Then align the new filter with the arrows and slide it in, similar to how you removed the old one. Then close and access panel and you’re done!
If you’re running into other problems with your furnace, there are a few other easy things to look for: making sure the furnace is plugged in and there are no blown fuses or circuits on your circuit breaker, and making sure the thermostat is set properly. If you’re still having trouble, Armstrong has supplied a list of error codes:
Single LED flash - Flame is burning when gas is off
Two/three LED flashes - Problem with the pressure switch
Four LED flashes - Problem with the height limit switch
Five LED flashes - Problem with the rollout switch
Six LED flashes - Problem with the pressure switch
Seven LED flashes - Problem with the ignitor
Eight LED flashes - The flame is low/dropping
Nine LED flashes - Problem with the voltage

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!

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!
