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.


Twintech’s Emergency HVAC Repair Services


Twintech Heating & Cooling offers prompt, professional emergency service for a wide range of HVAC systems, including:


Furnaces


Boilers


Heat pumps


Air conditioners


Ductless mini-split systems


Our technicians are trained to diagnose problems quickly and provide clear, honest recommendations—so you know exactly what’s going on and how it can be fixed.


Local Service You Can Rely On


Because Twintech is a local HVAC company, we understand the specific challenges homeowners face—from older heating systems to newer energy-efficient upgrades.


Our local focus means:


Faster response times


Familiarity with regional weather conditions


Experience with homes of all ages and layouts


Service that’s tailored to local needs, not one-size-fits-all solutions


When you call Twintech, you’re working with a team that lives and works in the same communities you do.


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.


Twintech provides emergency furnace repair to:


Restore heat as quickly as possible


Identify safety concerns like cracked heat exchangers


Prevent further damage to the system


Help protect plumbing from freezing


If replacement is the only safe option, we’ll explain your choices clearly and help you make the best decision for your home.


Emergency Cooling Repairs in Extreme Heat


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.


What to Expect When You Call Twintech


When you contact Twintech for emergency HVAC repair, you can expect:


Clear communication from the start


Prompt dispatch of a qualified technician


Thorough system inspection and diagnosis


Honest recommendations without pressure


Professional repairs focused on safety and reliability


Our goal is to reduce stress during an already frustrating situation.


Preventing Future HVAC Emergencies


While not all breakdowns can be avoided, regular maintenance greatly reduces the risk of unexpected failures.


Preventative HVAC maintenance helps:


Catch small issues before they become emergencies


Improve system efficiency and performance


Extend equipment lifespan


Reduce the likelihood of mid-season breakdowns


Twintech offers maintenance solutions designed to keep your system dependable year-round.


Final Thoughts


HVAC emergencies don’t wait for a convenient time—and neither should your repair service.


When heating or cooling problems strike, homeowners in the Durham Region and Toronto need a company they can trust to respond quickly and professionally.


Twintech Heating & Cooling is proud to provide reliable emergency HVAC repair when comfort, safety, and peace of mind are on the line.


If your system fails unexpectedly, expert help is just a call away.

by Aaron on Twintech Heating and Cooling

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.

by Linda on Twintech Heating and Cooling

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!

by Robert Rogers on Twintech Heating and Cooling

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.

by Robert Mizuno on Twintech Heating and Cooling

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!

by Ruth on Twintech Heating and Cooling

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!

by Anna Chin on Twintech Heating and Cooling

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!

by Connor Agnew on Twintech Heating and Cooling

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.

by Trevor Owens on Twintech Heating and Cooling

I returned from vacation to find my AC unit on the Fritz. After calling way too many places I connected with TwinTech. I’ve used the company in the past for my furnace so I was happy when I recognized Greg at my front door. He’s great and the service is always top notch. I’d highly recommend using twintech for honest, superior service in the Durham region. Thanks!

by Nicole Alain on Twintech Heating and Cooling

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!!

by Courtney Parkes on Twintech Heating and Cooling

Bob, Greg & Mitch make a great team! Quick appointment times, super knowledgeable, expert troubleshooting capabilities & very customer service oriented.
