Emergency HVAC Repair in the Durham Region

When your heating or cooling system fails unexpectedly, it’s more than an inconvenience—it can quickly become a safety issue.
Whether it’s a furnace breaking down during a cold snap or an air conditioner failing in extreme heat, fast and reliable service matters.
That’s where Twintech Heating & Cooling comes in.
We provide dependable emergency HVAC repair in the Durham Region and Toronto, helping homeowners restore comfort when it matters most.
What Counts as an HVAC Emergency?
Not every HVAC issue requires immediate service, but some situations shouldn’t wait.
Common HVAC emergencies include:
No heat during winter
Furnace or boiler failure in cold weather
No air conditioning during a heat wave
Burning smells or unusual noises from HVAC equipment
Systems repeatedly shutting down or failing to start
Suspected gas, electrical, or carbon monoxide issues
In these situations, delaying repairs can risk damage to your home—or your health.
Why Fast Emergency HVAC Repair Matters
In the Durham Region and Toronto, temperatures can swing dramatically throughout the year.
HVAC failures during extreme weather can lead to:
Unsafe indoor temperatures
Frozen or burst pipes
Increased humidity or moisture damage
Disrupted sleep and daily routines
Quick response isn’t just about comfort—it’s about protecting your home and family.

Emergency Furnace Repair During Winter
A furnace breakdown in winter is one of the most urgent HVAC emergencies.
If your furnace stops working, indoor temperatures can drop quickly—especially overnight.

Restore heat as quickly as possible

Prevent further damage to the system
Help protect plumbing from freezing

Summer heat waves can be just as dangerous as winter cold.
When your air conditioner or heat pump fails during high temperatures, indoor conditions can become uncomfortable or unsafe.
Our emergency cooling services help:
Restore airflow and cooling
Diagnose electrical or compressor issues
Address refrigerant-related problems
Improve system reliability during peak demand
We work efficiently to get your system running again as soon as possible.

Catch small issues before they become emergencies

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!
Very pleased with the professional service that TwinTech Heating and Cooling provided in replacing my furnace. I got several quotes from different service providers. Their price was excellent and they explained the features very well. We are very glad we went with TwinTech and highly recommend their services.
We were new homeowners in need of a second opinion. TwinTech Heating & Cooling were Amazing and professional. Very knowledgeable and great service all around. Recommend to anyone looking for honest and reliable services. Treated with respect and care. Thank you Greg, Mitch and Bob!
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!
Amazing experience with TwinTech Heating & Cooling! Their team was professional, knowledgeable, and efficient from start to finish. They installed my new furnace quickly and left everything spotless. The technicians took the time to explain everything and made sure I was comfortable with the system before they left. Great customer service and fair pricing. I highly recommend them for anyone needing HVAC services!
Great experience all around. Bob was sharp and easy to talk to, and Greg handled the installation perfectly. Would hire them again in a heartbeat.
I returned from vacation to find my AC unit on the Fritz. After calling way too many places I connected with TwinTech. Ive used the company in the past for my furnace so I was happy when I recognized Greg at my front door. Hes great and the service is always top notch. Id highly recommend using twintech for honest, superior service in the Durham region. Thanks!
I called Twin Tech when my air conditioning stopped working. Greg came over to diagnose the issue - the same day. He was able to diagnose the issue and resolve it quite quickly. Although it was a quick fix, Greg was very thorough in explaining the issue and provided great advice. Not to mention, I felt very comfortable having Greg in my home - which I consider very important when hiring a service provider. Twin Tech will be my go-to from now on. Thank you!!
Just hired TwinTech Heating & Cooling to do an A/C Unit removal & reinstall to allow for landscaping access on the side of my house, and they were wonderful!
Bob, Greg & Mitch make a great team! Quick appointment times, super knowledgeable, expert troubleshooting capabilities & very customer service oriented.
I would highly recommend them for all of your HVAC needs! Great job guys!!
