We had Grant and Greg Dainty quote to replace our 20 yr old furnace. I have known them for years and have had other jobs done by them ( AC and Pool Htr). The price was very reasonable and the job was completed in one day.

TwinTech was the right choice. Our consultation with Dave set the tone. Professional and knowledgeable, we even received a follow-up call within hours of our install completion, wow! TwinTech arrived as scheduled to install our A/C unit. Within minutes of arrival Greg noted and explained a few out of code faults on our furnace installed by another company, problems fixed, thanks TwinTech. Greg, Grant and "Subaru" Pete were meticulous start to finish. Highly recommended!

Twintech replaced our aging +20 yrs old Furnace & AC with the variable high efficiency Napoleon Furnace matched with the Goodman AC. Sales guy ,Dave was great, gave a no pressure estimate, explained about the Government Rebate program which they took care of completely including arranging the home energy audit. On the scheduled day Greg and his team arrived on time, did a great job and completed the same day , extremely professional and courteous, cleaned up everything , tested the system, Greg took his time to explain the setup. Very impressed with the Napoleon Furnace 9600 which did a great job in maintaining a comfortable temperature last winter and now with the hot weather the Goodman AC cooled the house in much less time than the old AC unit could ever. From start to finish Twintech were great and have no hesitation in recommending them 100%.

Dave from TwinTech was very knowledgeable, professional and thorough in the buying process. He helped us to identify the best furnace for our home and our budget. When we needed a new filter a year later and seemed to have a problem finding the right one, I called Dave up and he delivered a filter to me the next day! The cost was on par with other retailers, but it was this unexpected personal service that really was impressive. The furnace? Works like a charm.

Imagine, it's 5 minutes after the midnight countdown New Year's eve and the furnace quits. We called TwinTech fully expecting to leave a message and actually spoke with Greg, one of the owners! We had an immediate repair early the next morning & a new furnace within the week. We have entrusted TwinTech with all our home HVAC service needs for over 6 years. That's why this week with an opportunity to purchase a new BBQ, we called them 1st to see about a gas line install. It's chicken on the grill tonight! They are efficient, reliable, honest, hard working, and -- attentive is an understatement.

Wonderful customer service, starting from the job quote (Dave), to the clean install, to the follow-up. Twintech is a small company which installed my Napoleon furnace, A/C, John Wood tank, and ran the line for my gas dryer. The installation was completed as promised in one day. The work area was kept very clean, and they even took care of my old rental tank. The professionalism and wonderful customer service is second to none. They completed all of my rebate paperwork, and now I'm getting $2000 back! You will not be disappointed if you hire this company for your project.

I was referred to Twintech by a neighbour and was not disappointed. Not only was the customer service excellent their workmanship was second to none. Greg and Grant work extremely clean covering the pathway to the furnace room, labeling the essential parts, left the area spotless and were efficient. They cleaned up the mess left by the previous installers (wiring, improperly installed AC coil, and gaps in venting etc). They also ran through the operation of the new furnace and gave me some maintenance tips. Greg and Grant are professional and all around good guys. I will definitely recommend their service to anyone without hesitation.
