Durham Region Air Conditioning Repair, Service and Installation
The Payne gas furnace has built in diagnostics and is designed to assist with the identification and correction of faults. The furnace utilizes an LED, to describe its condition.This can be viewed through a port on the blower access panel. You can take corrective action in response to any faults indicated by the LED.
The number of short flashes of the LED represents the first digit of the two digit fault code. The number of long flashes of the LED represents the second digit of the fault code.
CODE: RED LED1 ON.
RESULT: Furnace is operating in emergency heat.

Class Act ! These guys were professional right from the quote stage through to installation. They know their stuff and took their time to help educate me. They take pride in their work and it shows. I would recommend TwinTech Heating and Cooling to anyone. Keep up the great work !!!

This Company is terrific. No high pressure sales and they deliver exactly what they promise to deliver. The new furnace is great and we now get consistent temperatures throughout the house. The installers were great and very efficient and completed the work on schedule on the promised day. Everyone representing this company was very aware of their presence in our house and worked diligently to keep our home as uninterrupted and as clean as was humanly possible. We did not need to go around the house to clean up after they left, what a nice surprise. We have had follow up by the company to ensure everything is to our satisfaction. How unusual in today's environment. The impression left by Twintech is that they care about us and our home. This is so refreshing in today's high tech world. Out thanks go out to Dave in sales and G, G, and P (the installers).

They were Timely and professional. They were very Knowledgeable with answering all of my questions.
Dec 23, 2018
The entire process was prompt and professional, from the initial quote to the installation of the new furnace. The team installed the new furnace and removed the old one in approx. 4 hrs. The guys were very knowledgeable and gave me lots of information. I have used Twintech before for a new A/C installation and new I was in good hands.

The overall experience dealing with this company was great from start to finish when getting a new furnace and ac this year. Everything was clearly explained to us during our consultation with Dave and there were no surprises with added costs. The work was done as expected and their response time to inquiries were very timely generally within a few hours or less. They are all very professional and was a pleasure to do business with them. Highly recommend to anyone looking for honest quality professional service.

From the initial contact we had an excellent experience with this company and all its personnel. Dave Gergley was an excellent, helpful, sales person and solicitous of our needs. He recommended only what was required and did not up sell or make any suggestions for products that we did not need, such as a new A.C. He explained the rebate process and basically outlined how to get the best furnace at the lowest price. When it was time for installation, the technicians could not have been more considerate, careful, attentive to detail, obviously committed to safety and optimum functioning of the appliance they were setting up. We have been perfectly satisfied with the functioning of the furnace and all aspects of acquiring it from the initial contact with Dave through to the installation process and follow ups inquiring about our satisfaction. Also they initiated the rebate process and contacted the appropriate inspection agency to carry it out. We highly recommend this company for all heating and cooling needs and we will contact them again when it is time to replace our A.C.

Twintech was excellent from the initial quote and throughout the install. They had a competitive rate for hot water tank and ended up buying the tank from them, had them remove the old tank and install the new one. The day of install they were prompt and out in about 2 hours. Professional , courteous really great guys. We took a look at my 30 year old furnace and they were able to offer some suggestions for future there too.

Ever since I turned on my furnace on Oct 2018 I hear a humming sound when the furnace fan kicks in. I called Adamson Air System who installed my furnace 7 years ago and couldn't figure it out the problem. I just wasted money to the guy who couldn't figure it out. I found Twin Tech via Amana / Goodman website. I checked the reviews from previous Twin Tech customers. I called Greg and was onsite on time this morning Sunday, Nov 25 2018. He figured it out what's wrong with the furnace and explained what the previous installer (adamson air system) did wrong when they installed it. His knowledgeable about his job. He recommend to replace the fun motor because the sound is not normal when it's running. Looking forward to see him again to replace the fan motor.

Our house is over 22 years old and I had been researching furnaces and A/C brands for a while and thought it was time to take the plunge. After calling three different companies to come in and quote the job, this one won me over. From the first visit from Dave all the way to the end of the install by Greg, Grant, and Piotr, I was glad to have picked this company. Dave was very knowledgeable and really took the time to explain what kind of quality installation I was going to get as well as showing me some of their previous work and certificates.
I was also surprised at how quick the installation took and how nice everything looked afterward, I mean it's only a furnace right? They even re positioned the furnace so that I have easier access to my filter and humidistat, awesome! If you are looking for a company that cares about their customers and is proud about the quality of work they do, along with a great and competitive price, then stop right here because you found it.

Once our AC Unit started to fail, I called our past Heating & Cooling provider for support. The response was we needed a new motor for our Furnace. It was time to check their Quote against the marketplace, I reached to other providers online. One of the owner of Twintech (Greg), called me and offered a preliminary Quote and recommendation online. The others needed to set an appointment and came to measure and spend 1 hour before offering a quote. Then I asked Twintech to come finalize their quote to make sure their recommendation was aligned and met our needs.
Twintech was professional throughout the process, easy to deal with (Web, Phone and in Person), price right and met their commitment. Their team expedited the process and installation, arranged for a energy assessment for available rebates and most importantly, delivered on their commitment and managed to do a few extras. They installed a New Furnace, AC unit and Nest thermostat in a day, remove all older units, left the house and outdoors clean and without any debris. Great to be able to support a Local Company, Neighbour and Professional team - Well Done Team Twintech !!!
