I contacted various companies when looking to install a new furnace and I found Twintech to be transparent with their communication and approach. They had options to suit my various requirements and the price vs quality was very good. The after installation communication was also very good and they answered all queries I had.

by Private User on Twintech Heating and Cooling

My furnace broke down last month. The team was quick to respond, courteous, professional and mindful of COVID-19 concerns. I highly recommend them if you are considering replacing or servicing your HVAC equipment.

by Private User on Twintech Heating and Cooling

by Dorothy on Twintech Heating and Cooling

Had furnace and air conditioning unit put in. They did an excellent job great price and everything clean as can be, I was very pleased

by Barry on Twintech Heating and Cooling

All winter I have had an issue with very little heat reaching the 2nd floor of our home. After this past winter ended I decided to look into this. I found Twintech Heating and Cooling on line and started the process. After explaining my problem I had a call form Twintech and the tech came out and walked through things with me. The problem was the heating vent pipe had been dropped down in size by someone years ago causing little heat reaching the 2nd floor. Further into checking out the older furnace and AC they found a few things not properly installed by the last install of the old furnace and also that the AC was on it's last legs. I asked for a quote and waited a few days and we decided to go ahead with Twintech. They called a few days before to set up an installation time and date. The day of the install the guys were a half hour early which was a plus. The day of the install was great, the guys worked away removing the old furnace and AC.After which they installed the new furnace and AC. After they cleaned up the basement with all their tools and scrap metal etc. they came back inside to walk thru what they did. They also tested both the furnace and cooling systems to make sure everything worked and I the customer was happy. I now have heat on the 2nd floor for next winter. The guys from Twin tech were very professional. Their work habits and knowledge of the job was excellent. Their workmanship was just excellent, it was just up there with my standards as a homeowner. I am very pleased to have chosen Twintech for my new furnace and AC.. If I had to rate this experience with Twintech this company is a 10 in my books.Product,workmanship and customer care says it all.

by Craig in Whitby on Twintech Heating and Cooling

I called Twintech during the Covid 19 crisis because our furnace was broken and it was still very cold during the nights. Dave answered all of my questions by phone but wanted to come have a look but only if our family felt comfortable having someone visit during the uncertainty surrounding the pandemic and was able to attend that very same affternoon.

He was very courteous and informative but most importantly he respected his and our safety by wearing medical gloves in our home and maintaining proper physical distancing. He reviewed the various options of the products that suited our needs going over not only price but quality of workmanship, warrantees and where the product was manufactured which were all important factors in making such a large purchase. You could tell that Dave had been in this industry for a very long time.

The installation was done by a fine young gentleman the very next day and we now have a toasty warm home to ride out this crisis in while humming along at 96% efficiency!

I would recommend this very professional, small family business for anyone in need of HVAC equipment or maintenance.

by Lucy in Markham on Twintech Heating and Cooling

My special thanks to Twintech teams! They had replaced my furnace and A/C, and installed a new humidifier for me 2 weeks ago. Dave, the sales manager, not only provided me with an honest quote on the best HVAC products with best quality and warranties, he also arranged portable heaters for me and sent supporting docs to energy company for energy audit. Above and beyond service!

Greg, Grant, Mitch had worked tirelessly and professionally to perform the HVAC installation. They worked with professional tools, and performed proper measurement readings after installation. They are very patient with all my questions, and very pleasant to communicate.

Great work guys! This company sure knows their products and they stand behind their services. My home comfort level has improved! I am glad that I can support an ethical and honest local family business.
