My 19 year old furnace stopped working when the cold weather hit in November, and I was left without heat. I interviewed several companies and found TWINTECH HEATING and COOLING to be very knowledgeable, quick to respond to my inquiries and very competitively priced.
Dave provided all of the information and pricing ahead of time and set up the appointment for the installation. Greg and Mitch arrived on time to do the installation and worked quickly and efficiently to complete the job.
After the completion of the installation, Dave followed up to ensure that everything was working well and that I didn't have any concerns.
Overall, this was a low-stress and flawless experience from start to finish. I would highly recommend TWINTECH HEATING and COOLING to anyone that requires a new furnace.

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.

Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!

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!
