Durham Region Air Conditioning Repair, Service and Installation
Carrier furnaces are sturdy, but the models can vary widely in terms of size and design. When it comes to fixing one of these furnaces things can get complicated. Complicated fixes should be left to the pros but luckily there are a few simple troubleshooting steps that anyone can follow to get Carrier furnaces up and running again.
Firstly, make sure your Carrier furnace is getting power. If it isn’t, check your circuit breaker and fix any tripped circuits. Next, check the thermostat and make sure it’s in the right mode. Set it to the heat position and input your desired temperature (ideally above 70 degrees for proper heating). The next steps include checking your furnace filters to make sure they’re clean and replace them if they aren’t.
If your furnace still isn’t heating: The problem could be the igniter as it may be cracked or faulty. Check it for cracks and if you find anything, replace it. If you don’t find anything, you can check for continuity with a multimeter.
If your furnace is cycling irregularly: then your thermostat may be incorrectly adjusting itself. To fix it, see if the thermostat has an adjustable calibration scale. If it does then adjust the heat anticipator. If this doesn’t work, then you should call your HVAC repair company as you may need a new thermostat.
Taking the time to go over these few simple things may just help save valuable time and money! Any regular maintenance you can do (like changing the filters) will keep your Carrier furnace happy for a long time.

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 !

Our furnace was rattling, as soon as we put our air conditioner on this past week. We had researched looking for a company that was Registered with Better Business Bureau, and this company TwinTech, had A+ Rating. Scott, was immediately helpful via text/phone and sent his technician as soon as he was able...Mitchell/technician provided great professional service. Thank you TwinTech.

I contacted various companies when looking to install a new furnace and I found Twintech to be transparent with their communication and approach. They had options to suit my various requirements and the price vs quality was very good. The after installation communication was also very good and they answered all queries I had.

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.

Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!

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!
