Is your water heater at the end of its lifespan? Time to replace it with a new system? Twintech is ready to help! We provide fast, affordable, and efficient water heater repair, maintenance, and installation across Oshawa.


As your water heater is used day in and day out, expect to have to perform some amount of repair. If repair is not an option, we will help you determine the best replacement. Water heater repairs with Twintech are upfront, cost-efficient, and effective. You can trust our licensed technicians for satisfactory service.


If your water heater is doing the following, call us:


  • - Not supplying adequate hot water
  • - Taking a long time to heat water
  • - Leaking from the water heater tank
  • - Making noise from the water heater tank


Depending on the type of water heater you currently have in your home, life expectancy can range anywhere from 11 years to 20 years. If you would like to find out if your water heater is due for a replacement, feel free to reach out to Twintech. We can come to your house, inspect your water heater, and help you determine the best replacement timeline and option.


Whether your water heater is failing to produce anything but lukewarm water, has sprung a leak, or is simply outdated, we can help you find the perfect replacement for your home.


We can replace your current system with the following types:


  • Conventional – Water is stored in a large tank (varying sizes available) and heated by electric or gas energy. High-efficiency models can reduce water heating bills by as much as 7 percent.
  • Tankless – Water is heated only as needed, providing access to unlimited and instant hot water through a tankless water heater. May reduce water heating bills by as much as 30 percent.
  • Hybrid – Combines the conventional tank storage style with a heat pump and uses existing water / electrical connections. Can reduce water heating costs by as much as 60 percent.


Proper maintenance can help prevent costly water heater repairs. As we inspect your water heater, we can quickly repair minor issues before they become major ones. However, if you do experience major water heater problems, we offer 24/7 emergency services at no extra charge. The quicker you call, the more quickly we will be able to help you get your Oshawa home up and running again!

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 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!!

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!
