Emergency HVAC Repair in Whitby
Posted On: February 17, 2026
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

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.

Faster response times

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.

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.

On coldest night of the year our furnace quit. At 8:40 in the morning Greg arrived and gave us a diagnosis and a recommendation. By 2:30 we had a new furnace and were warm again. Great company. Great customer service. Good reasonable price.

Twin tech team was very efficient and prompt. They provided a quote within hours of request and got the job done on time. No disruption to home function. We would highly recommend this team. Job well done.

Our furnace bit the dust, and Twintech came out to troubleshoot and diagnose the problem within a couple of hours. Mitch was super helpful, patient, and answered all of our questions. When we decided to get the furnace replaced, the crew was over first thing the next morning and did a fantastic job. Not only did they complete the job in a few hours, but they cleaned up and respected our house as they went, and answered all of our follow-up questions. I've used Twintech for our HVAC needs in the past and will continue to do so. I'd recommend them to anyone, and it feels good to support a local, family-owned business.

Dave and the Twintech team were fabulous from day 1 and helped us through the process to identifying a new furnace and AC unit. This was our first time through this process and Dave did a thorough job explaining all the components and was very patience answering all our questions. Dave provided great insights and fair pricing.
The Twintech team did an awesome installation. Very clean and efficient. I would highly recommended their service.

We had a new Amana furnace installed by Twintech and we were very pleased with the installation. It is nice to have a warm house again.
Jul 3, 2022
Excellent job. Excellent service. Competitive price. Its rare to find a company with the knowledge and professional results we have experienced with Twintech. The clean and neat installation with attention to detail and drop sheers to respect our property is a clear indication of Twintechs high level of integrity. The 1-1/2 gas line upgrade they did for our pool 3 years ago was awesome. Can't say enough. Thank-you Twintech.

Twitch did a great job with the installation of our new furnace. I really appreciated their honesty and I could trust what they were telling me. Another company tried to suggest significantly more work at a greater cost claiming it was necessary to meet current building code. Twintech is very fair. All staff I meet were friendly, polite and trustworthy. I would recommend Twitch for a furnace.
Jul 3, 2022
This is a professional team that's easy to deal with. I would strongly recommend them
Jul 3, 2022
Very professional firm from start to finish!
They removed the old oil tank and furnace. They installed air conditioning and a new propane furnace.
Professional installation, on time and no mess.
Very pleased with their work and would highly recommend the company. Our house is three stories so they spent the time to do all the calculations to make sure we would have great performance on each floor.
Thank you again!

Upon a routine yearly maintenance, it was discovered there was a leak in the heat exchanger and a I needed a new furnace. I know nothing about these things and was completely stressed out. The company I had the maintenance plan with quoted me a huge number to rent a furnace, I just wanted to cry. Then I spoke to Dave at Twintech. He was so knowledgeable and calming, provided me a fair quote and within a few days I had an amazing crew show up to my house and install my new energy efficient furnace! I have already recommended these wonderful people at Twintech to a good friend of mine. Thank you Twintech!!
