Winters in Canada can be tough, and they can be even less fun if you have gas furnace problems. We rely on our furnaces to keep us warm and cozy no matter how frosty it gets outside. While issues can be big and require a complete replacement of the furnace, often issues are caused by smaller things. Here are some of the common furnace problems:


- Dirty filters
- Ignition or pilot control problems
- Cycling between on and off
- Malfunctioning thermostat
- Broken blower belt
- General mechanical problems
- Cracked heat exchanger


Many of these problems can be prevented with simple maintenance, such as making sure your filters are changed and getting regular furnace maintenance. At Twintech, we've been fixing gas furnaces in the GTA for over 30 years, so whether you need a simple furnace check-up before winter hits or a bigger repair, call us for quick, easy and simple service! Even if your furnace breaks down unexpectedly in the middle of winter, if we can, we'll be there the same day to install a new one! Just ask Anna from Ajax:


"On one of the coldest days of winter, our furnace stopped working. Grant showed up a short time later and a new furnace was installed the same day with no troubles at all. Best of all, we received a higher-end furnace than what was offered by our previous company and at a cheaper price."


So if you find yourself stuck in the cold this winter with gas furnace problems, just give Twintech Heating & Cooling a call at 1-844-894-6832 for a free consultation and quote and quick, easy repairs!

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.

by Robert, Ajax on Twintech Heating and Cooling

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.

by John Armstrong, Pickering on Twintech Heating and Cooling

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 !

Flawless transaction. They did exactly what they promised, showed-up on time, cleaned-up, and were highly professional. Highly recommended.

Great experience getting an old furnace replaced.
Sales Guy (Dave) was great - honest, responsive, and friendly.
The work itself was done quickly and we are very happy with the outcome, thank you! We recommend TwinTech!

by Private User on Twintech Heating and Cooling

This review is late coming so my apologies to the amazing Twin Tech team! I contacted Dave at Twin Tech for a quote this past Feb (as I was collecting a few) and his recommendation was excellent. From the first meeting with Dave to the team installing the new furnace, not once did i feel uncomfortable . The team were extremely professional yet personable and clean and tidy. Decent companies still exist!
The new furnace just purrs and its just amazing the difference it has made!
(PS my sibling ended up getting a furnace from them as well)

by Private User on Twintech Heating and Cooling

The service was Twintech was excellent.
Dave our salesperson was easy to talk to and was professional. The unit recommended meets our needs and budget.
Greg and his team arrived on time for the installation and even got rid of the garbage the contractors left in our furnace.
Would definitely recommend Twintech.

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 definitely recommend TwinTech!
