Emergency HVAC Repair in Oshawa

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.

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.

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.

by Samta Chanana on Twintech Heating and Cooling

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 air conditioner failed. Made a call and within 15 min a technician was at our door.
The issue was fixed and many suggestions were provided.
Thanks to Mitch. Great service !

by Kazuko on Twintech Heating and Cooling

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.

by Private User on Twintech Heating and Cooling

My furnace broke down last month. The team was quick to respond, courteous, professional and mindful of COVID-19 concerns. I highly recommend them if you are considering replacing or servicing your HVAC equipment.

I was very happy with the installation and price. I would definitely recommend. Thank you Twintech.

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!
