Has your furnace stopped working? Is it not heating your home properly? At Twintech, our licensed repair experts are ready to provide emergency or non-emergency furnace repair services. We have HVAC technicians available 24/7 across Ajax for emergency furnace repairs.


Your comfort is important to us. We have outfitted our service vehicles to provide immediate furnace replacement or service with parts and even full units by Napoleon and Trane. That means shorter wait times to get your heat back on.


Are you hearing strange noises from your furnace? You might need replacement, repair, or maintenance services for your home’s HVAC equipment. Don’t ignore the first signs of trouble — it’s always a good idea to call the professionals for a consultation.


When you schedule a furnace repair with our Ajax team, you get:


  • - Top-quality service from fully licensed technicians
  • - A fixed-price quote upfront that includes all parts and labour – no hidden charges
  • - A complete diagnostic and safety check of your equipment
  • - A comprehensive home care report outlining the health of your heating equipment


After servicing thousands of homes, Twintech understands firsthand what happens when people put off maintenance service. Though we offer emergency service 24 hours a day, we know that’s not what you want. To make sure your heater never stops working and keeps you warm throughout the year, call us for an annual maintenance check-up.


Ask the following questions while deciding to keep or replace your heater:


  • - How Old Is It? — Heaters don’t last long past 10-12 years. Age is a critical factor.
  • - How Often Have I Repaired It? — If your repairs (or anticipated repairs) this year come out to 50% the cost of replacement, it’s time to get a new model.
  • - How Much Does It Cost Me? — If your heating bills are continuing to rise despite regular maintenance, it may be time for a new model.
  • - How Well Does It Work? — If your home isn’t as warm as it used to be, then that’s also a valid reason to replace your system.


Our technicians know the ins & outs of these systems and are able to offer service at every level of need. Whether it’s installation, maintenance, or repairs, Twintech’s your best choice for all things furnace.

by TraceyG from Toronto on Twintech Heating and Cooling

Last night was the coldest day of the year so far and I woke up to my house being 54 degrees... I called Twintech at 2:45am and Greg was on site by 3:30am. The furnace required a part and he returned to his shop and came back to my home around 4:15am, furnace up and running by 4:30am. THANK YOU TWINTECH! Your service is second to none.

by Cristelle from Ajax on Twintech Heating and Cooling

After much research & getting 4 quotes, we hired Twintech team for our new furnace installation, prices were fair, they carried great product brands & more importantly installation was expertly done by one of the owners (Greg & his assistant Peter) which gave me an added piece of mind. Dave was very organized & answered all my questions in great detail, especially re: the Enbridge & Govt. rebate program.

by David from Pickering on Twintech Heating and Cooling

My old air conditioner was 20 years old and developed a Freon leak and it was more cost effective to replace rather than repair. There are a large number of heating and air conditioning companies available in my area so I contacted several for quotes. Twintech heating and cooling responded quickly to the inquiry I left on their website and their sales person Dave came by the following day. He was knowledgeable about the field and was able to show copies of the various refrigeration and gas fitting licenses along with workmens compensation, TSSA and other certifications. He also suggested a particular manufacturer and model of AC unit appropriate to my house and gave me a quote. Since the price was reasonable, service had been good and the reviews on the internet were also good, I decided to purchase an AC unit from them. Installation was quickly scheduled. They showed up on time, did a good job installing the new unit including some sheet metal work to get the new heat exchanger to fit in the furnace duct, and cleaned up afterward. In addition, they noticed that my existing AC was installed too close to the furnace exhaust (based on building code) and were able to mount the new AC the appropriate distance from the exhaust. Overall, they did an excellent job and were a pleasure to work with.

by LP from Pickering on Twintech Heating and Cooling

All interactions from sales to installation were Courteous and professional. The installation was seamless and the attention to detail including clean up was outstanding. I highly recommend TwinTech Heating and Cooling.

by David in Pickering on Twintech Heating and Cooling

Twintech's Salesman Dave arrived promptly was friendly and courteous, listened and assured us the installation would be completed according to our requests. The crew arrived early morning on May 11th, 2018 and worked through till late afternoon non-stop. They were very friendly, very professional, their expertise was excellent, their workmanship outstanding and the installation was completed in a timely and efficient manner. We were completely satisfied and happy with the quality of the work.

by Jennifer in Toronto on Twintech Heating and Cooling

I had cold and hot spots all over my 70 yr old home. My furnace is quite new and Greg optimized the fan and furnace. The original installer just took it out of the box with factory settings and installed it- basically running at 50% of capacity. Greg also routed heat into my laundry room, yeah - so now I can renovate laundry room - thanks Greg. He is honest, professional and knowledgeable. I will be calling him back in the spring to optimize my AC as well.

by Happy Homeowner in Toronto on Twintech Heating and Cooling

Wonderful from beginning to end. I tend to fret and worry about home improvements but the excellent team at TwinTech put my mind as ease. They listen, they are patient and best of all ... the work they did is amazing! I chose the Goodman 80K BTU 2 stage furnace and the matching Goodman air conditioner. Greg, Grant and Poitr "Peter" arrived on time, took great care, explained everything to me and they answered all of my questions. They carefully adjusted the factory settings to optimize the furnace for my house and they also checked the duct work in the basement. Dave, the Sales Manager, came by to say "hello" and to see if I was happy. YES, I am happy with the work! The furnace is very quiet. I have it running on low just to circulate the air in the house and it's so much quieter than my old furnace. When I need new duct work for an upcoming basement renovation TwinTech will be my first choice. I highly recommend TwinTech. PS. They were even nice to my dogs.

by Les G. from Pickering on Twintech Heating and Cooling

Greg was prompt on the scheduled day of installation and the work was done well within the time estimated beforehand. Installation was neat and the equipment and scope of work was as specified in the quote. One item I must point out is that we were faced with a "No Heat" situation the day before the scheduled installation and Greg came out to address it free of charge. Not only that, but he also corrected an installation fault with our smart thermostat that was not part of the original job, again free of charge.

by one19 in North york on Twintech Heating and Cooling

Greg came by to do a routine furnace checkup. He was very knowledgeable and professional, letting me know what's being checked/adjusted and giving me tips to ensure everything runs smooth. Very honest and upfront about what's working fine vs. what may need to be fixed/replaced. He didn't attempt to up sell anything that wasn't necessary. I'm glad to have finally found someone I can trust and rely on for all my HVAC needs - furnace, A/C, and hot water tank.

by Paul M. from Toronto on Twintech Heating and Cooling

I'm very happy with the work that was done. Everyone from salesperson to the installers were friendly and professional. They were on time and cleaned up the job site after it was installed. They also answered all my follow up questions promptly. I wouldn't hesitate to work with them or recommend them again.

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.
I would highly recommend them for all of your HVAC needs! Great job guys!!

by Jacqueline Graham on Twintech Heating and Cooling

Twintech Heating & Cooling installed my furnace in 2022 and in fall of 2023 installed my Panasonic Heat Pump. Greg and Mitch did a great job. Helped me through the rebate process. Super happy with the Heat Pump. Only used my furnace 5 times this winter. Energy bills lower, carbon emissions lower.Thank you Twintech. I recommend highly!

by Bill Grainger on Twintech Heating and Cooling

Just had a new furnace installed by Twintech. I can’t express how great these guys are at what they do. From the sales to installation they were professional all the way. Very reasonable pricing and courteous during the installation and willing to answer any questions I had. Highly recommended !!!
