Durham Region Air Conditioning Repair, Service and Installation
Coleman furnaces are tough machines, but furnace trouble is never far behind. Furnaces work by drawing in cool air, heating it, and then pushing the now-warm air through your ducts and into your home. It’s a simple process in writing, but in reality, there are so many different parts and units that make up the furnace system. If you’re having trouble with your Coleman furnace, there are some things you can do before calling your HVAC repair company.
If your furnace isn’t providing enough heat, first try turning up the thermostat by a few degrees. Every home is different and may require different base temperatures to heat properly. Next, make sure all the vents are open and that the air filter is clean. If neither of that help, then the problem may be due to dirty burners or a blower motor's fan belt that’s loose or frayed. These things should be fixed by a pro.
But if your furnace isn’t working at all then you should check the power. Make sure it’s plugged in and check your electrical box to see if there are any blown fuses. After that, make sure the power switch on the furnace is in the “On” position. If it’s still not working, come back in about an hour as the motor may just be overheated. Next, check the pilot light and if it’s out, refer to the manual on how to re-ignite it. If all these steps still don’t get your furnace back into shape, then you’ve done your part and it’s time to call in a professional!

Very pleased with the installation of our new furnace and A/C unit. From quotation stage to the completion of the job Twintech was very professional.
Thank you for a job well done.

My old water heater quit on me. I called TwinTech. In less than 4 days, I had my new water heater installed and the old one taken away. The whole process was quick, easy, pleasant, and well done. This is the third time I've dealt with TwinTech and I've been satisfied each time.

I had them replace my furnace last year. When it came time for the air conditioner this year, I did not hesitate to call Twintech again. I will also have them perform regular maintenance on them.

We required a new HVAC replacement after running the old
system for 18 years.
Dave understood our requirements and gave us a quote that
covered all the necessary items.
Installation was fast and very tidy. Everything works as
it should. Our thanks to Greg, Mitch and others for their
excellent work. Recommend this family owned business to
anyone else, considering HVAC or other work.

I needed a new furnace and A/C to replace my 21 yr. old units, and went to the internet to view potential companies in May, I received 3 quotes,
and chose Twintech based on their salesman Dave who was very detailed and covered off everything on what Twintech was all about,
an extremely dedicated company with so many years of experience, and after reading the on line reviews I was sold on Twintech, who did not disappoint as the installation team were top notch with Greg leading,
I would highly recommend this company without any doubts, in my books they are first class all the way. Our new Amana furnace and A/C are working perfectly !

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!
