Ever since I turned on my furnace on Oct 2018 I hear a humming sound when the furnace fan kicks in. I called Adamson Air System who installed my furnace 7 years ago and couldn't figure it out the problem. I just wasted money to the guy who couldn't figure it out. I found Twin Tech via Amana / Goodman website. I checked the reviews from previous Twin Tech customers. I called Greg and was onsite on time this morning Sunday, Nov 25 2018. He figured it out what's wrong with the furnace and explained what the previous installer (adamson air system) did wrong when they installed it. His knowledgeable about his job. He recommend to replace the fun motor because the sound is not normal when it's running. Looking forward to see him again to replace the fan motor.

Our house is over 22 years old and I had been researching furnaces and A/C brands for a while and thought it was time to take the plunge. After calling three different companies to come in and quote the job, this one won me over. From the first visit from Dave all the way to the end of the install by Greg, Grant, and Piotr, I was glad to have picked this company. Dave was very knowledgeable and really took the time to explain what kind of quality installation I was going to get as well as showing me some of their previous work and certificates.
I was also surprised at how quick the installation took and how nice everything looked afterward, I mean it's only a furnace right? They even re positioned the furnace so that I have easier access to my filter and humidistat, awesome! If you are looking for a company that cares about their customers and is proud about the quality of work they do, along with a great and competitive price, then stop right here because you found it.

Once our AC Unit started to fail, I called our past Heating & Cooling provider for support. The response was we needed a new motor for our Furnace. It was time to check their Quote against the marketplace, I reached to other providers online. One of the owner of Twintech (Greg), called me and offered a preliminary Quote and recommendation online. The others needed to set an appointment and came to measure and spend 1 hour before offering a quote. Then I asked Twintech to come finalize their quote to make sure their recommendation was aligned and met our needs.
Twintech was professional throughout the process, easy to deal with (Web, Phone and in Person), price right and met their commitment. Their team expedited the process and installation, arranged for a energy assessment for available rebates and most importantly, delivered on their commitment and managed to do a few extras. They installed a New Furnace, AC unit and Nest thermostat in a day, remove all older units, left the house and outdoors clean and without any debris. Great to be able to support a Local Company, Neighbour and Professional team - Well Done Team Twintech !!!

In October 2018, I contacted Greg at Twintech to do a furnace cleaning. Greg discovered that my furnace, installed in 2006 by another company, had been installed incorrectly, leading to restricted air flow. The heat exchanger was also defective. As well, my furnace was too large for the size of my house.
In my opinion, the biggest concern most of us have as consumers is that we have no idea of the quality or knowledge and experience of the technicians any heating and cooling company will send into our homes. I could have avoided having my 2006 furnace installed improperly (leading to early replacement), had I known about Twintech then.
With Twintech you get it all. Because Twintech is a smaller company you can rest assured that the only technicians who will work in your home are Greg and his twin brother Grant who are co-owners and fully licensed and certified with over 30 years of experience in installing and servicing heating and cooling equipment. They are both friendly and personable and answer all your questions. Their workmanship is outstanding. We had a 2 stage, variable speed Goodman furnace installed. My wife and I noticed a difference in the heating and even temperature of our 2 storey home almost immediately. Our old furnace always heated too much on the main floor and too little upstairs. We are also impressed with how quiet the furnace is.
Twintech's office manager, David Gergley, is equally friendly and not only gave us a competitive quote to replace our furnace (we sought other quotes), but also went above and beyond my expectations when he made arrangements with an energy audit company so that we would be considered for a grant from Enbridge and IESO.
Needless to say, I give Twintech a 10 out of 10 and highly recommend them!

Clean, Fast and Efficient Work. Between all the quotes I received Twintech was a few dollars less and offered the best warranty.
Oct 29, 2018
They did an excellent job. Everything was very well explained. At the end of the job everything was very well cleaned up.
Nov 1, 2018
Twintech offered me a competitive price but more importantly great sales and installation service. They did everything with attention to detail and quality workmanship that is hard to find in this day and age. Dave who first game to visit me answered most of my questions and probed about my needs. For the technical/install questions he was unable to answer he quickly had Greg and Grant the owners answer for me. They did not cut corners on the installation or do anything to simply save time. They stayed into the early evening to complete the job and removed all my old components and even fixed up mistakes other workers ahd made in the past. I would highly recommend them and use them again if the need arises in the future. If you are looking for service or new equipment I would highly recommend Twintech be on your list of Heating companies to get a quote from and ask your questions to.

The company epitomizes high quality service: from the initial client interaction with Dave to the installation and follow up with the technical team. One of the key features I look for is the ability of a technical person to talk to and not talk down to the customer when responding to questions and I had quite a few, all of which were very professionally addressed. I was also quite impressed with the follow up service, promptness, the obvious competence of the team who left no stone un-turned to ensure I was a satisfied customer. Thank you guys.
Nov 9, 2018
All staff concerned were total professionals. Sales rep Dave was like having an old friend at your house. No up selling or pressure, just good honest facts and figures. The owners and assistant who installed our unit worked quietly, efficiently and left our home clean. We could not have been happier with the service and attention we were given. We are so happy a family member recommended Twintech. She said "don't call anyone else, just call them...they are amazing". And they were!!! Thank you guys for the great work!!! A. Johnson

We are completing a large project adding an addition on to our house and couldnt be more pleased with our decision to trust Twintech with our hvac work. They removed and replaced the furnace, installed a new A/C unit, swapped our tank water heater for a tankless unit, and completed ducting and new A/C lines through the addition. Without hesitation we would recommend Twintech to anyone.

Feb 18, 2025
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!
Feb 18, 2025
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!
Feb 18, 2025
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.
