Durham Region Air Conditioning Repair, Service and Installation
Rheem furnaces are all equipped with an advanced 7-segment diagnostic display you can use as a guide if something goes wrong with your heating system. Unlike many other furnaces, Rheem ones don't use flashing LED light sequences to indicate errors, and the display will instead give you a simple code you can use for diagnostics. For instance, 0 means the unit is in standby, while H means the heat is on.
The flashing LEDs on your furnace will correspond to a specific fault code that is shown here on their diagnostic chart.

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

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!
