When was the last time you hired an HVAC technician for maintenance checks and furnace services Oshawa? Winter has finally arrived and if they aren't already, your furnaces are going to be working overtime. That's why it's important to get your furnace checked out annually by an HVAC expert because the last thing you'll want is to get stuck with no heat in the middle of winter.


There are a few things you can do to keep your furnace working efficiently, such as regularly changing the filter. But the majority of tests and checks should be left to the pros. At Twintech Heating & Cooling, we've spent over 30 years repairing furnaces in Oshawa and the surrounding area. We've helped many people stay warm over all those winters and we'd love to help you out too! Look at what one Oshawa customer had to say about Twintech's service:


"My father woke up to no heat one morning... TwinTech made the time in their schedule for what they judged to be an emergency: no heat in the home of an elderly person. They recommended an upgraded furnace unit and explained that we would qualify for a rebate that would bring the price down to that of a lower model. They set us up with the rep from the MNR that covers the rebate so that we didn't have to deal with the paperwork & phone calls ourselves. Installation was quick, efficient, & smooth. We were so pleased with their service we ordered a new water heater too."


To get started, just give us a call at 1-844-894-6832 to set up a free consultation and get your furnace services Oshawa and maintenance checks done today!

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!

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.
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 !!!
