by Steve V, Toronto on Twintech Heating and Cooling

Our old water tank was installed in 1997. Wasn't working as well as it should so we looked into a tankless as it is more efficient and a space saver! we had used Twintech in the past for a furnace cleaning and were satisfied with that so we decided to ask for a quote for the changeover. Gary arrived and provided the options and the quote fit within our budget so we decide to go with them after receiving a few alternative quotes from other companies. They did what the said would be done and it was completed within a reasonable time frame! Removal and cleanup of the old tank was seamless. We are now enjoying consistent and efficient Hot water! I recommend Twintech and would use them for future projects!

by New AC Unit + Humidifier on Twintech Heating and Cooling

One of the most honest HVAC companies out there! Dave was very helpful and informative in helping us choose a new AC unit. While they weren’t the lowest quote, we went with them because we trusted Dave and he was the most honest guy out of the companies that quoted us.
Greg and his crew who installed the unit were very professional and did a great job. If I could do it over again I would choose Twintech again.

by Private User on Twintech Heating and Cooling

Relocated and replaced our air conditioning unit. Fast, professional, and high quality service. We would definitely use them again for future projects!

by Ian, Toronto on Twintech Heating and Cooling

The term excellent or incredible does not seem high enough praise for the Twintech Heating and cooling company that recently replaced our 15 year old furnace. To start with, the response from Dave at Twintech to our original pricing request was the quickest and most professional of the 5 prices we received which included two of the primary natural gas providers. The Twintech pricing was the most competitive by a considerable margin.
We had Dave visit our home to confirm all pricing which he did and scheduled us for next day installation which was not offered my the majority of the other providers.
The installation; the team arrived on time and provided coverings to all of the hardwood flooring and stairs and proceeded with the removal and reinstallation of the new furnace, the workers predicated six hours and were completed in five hours. I have to mention how courteous and polite the workers were each time we interacted with them from start to finish.
The final result was amazing, all materials were cleaned up and removed from the house and the workmanship very impressive.
One feature that really stood out for me which shows a high level of professionalism was that we had various condensation hoses from the furnace , humidifier and an air filtration unit meeting at the one drain, the installation crew ran PVC tubing including elbows along two sides of the furnace to guide the hoses into one PVC tube at the drain, it looks great!
When the install was completed and tested the Twintech technician guided us through the features and recommendation's for care of the new furnace.
We highly recommend Twintech to anyone for the outstanding service provided to us.

by Stephen, Pickering on Twintech Heating and Cooling

I didn't hesitate to call Twintech in for a 2nd time as they did an outstanding job installing my new furnace last year. This time my 18 year old air conditioner was on its last legs. Greg and the team are top notch, highly skilled technicians. The job was executed in a timely and professional manner. Greg was extremely thorough and went the extra mile to make sure everything was operating efficiently. Lastly, Dave is a true gentleman and really made the customer experience pleasurable and worry free. Always remember that good work ain't cheap and cheap work ain't good.

by Derek, Whitby on Twintech Heating and Cooling

It's so hard to find solid companies these days, but I was very pleased to find one in Twintech. Greg and his crew were very clean, respectful and professional. We were most impressed at how all the things they said they would do, were done. Sounds strange, but usually when a contractor comes to your home they say they will take care of this and that, make sure this is done, etc but when the work starts you have to constantly remind them of your previous discussions. Greg ensured every item he said he would do was done, no reminders required. The work was done right, at a fair price and on time. We will be sure to call them when our A/C unit dies (fingers crossed that's not going to happen too soon :) )

by Patrick, Toronto on Twintech Heating and Cooling

Replaced our aging hot water tank with a tankless system. Excellent work, fast efficient and clean.

Walked us through the new system and recommended maintenance schedule.

This is our second time working with TwinTech and we are very happy with the quality of their work and professionalism.

by Troy, Toronto on Twintech Heating and Cooling

Efficient work and great follow up by the team at Twin Tech. Great product and communication.

by Peter, Pickering on Twintech Heating and Cooling

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.

Peter, Pickering

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!

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!

by Connor Agnew on Twintech Heating and Cooling

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.
