I received three quotes before deciding to choose Twintech. Dave's prices was much more reasonable than the competitors. I most appreciated their honest recommendations. Others tried to oversell their products and services. Thank you Dave!

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.

Our 20 year old furnace broke down during the first cold weekend this past November and our usual HVAC company never returned our phone call. Their loss, missing out on a sale since we didn't want to spend much fixing an old furnace and our 40 year old air conditioner was also long overdue for replacement. We proceeded in obtaining three different quotes for furnace and air conditioner replacement, and proceeded with the one we received from Twintech.
Dave was friendly, knowledgable and accommodating to our schedule and provided with us with a price that fell in the middle of the three quotes that we had. We felt that the Amana furnace and air conditioner he quoted us on were the best products and value offered to us and felt most comfortable with the professionalism and reputation of Twintech.
Greg, Grant and Mitch were at our house for installation the day after we decided to proceed. The guys were friendly and informative, the job was completed efficiently and workmanship appears excellent. Our house is certainly much more comfortable with the new two-stage variable speed Amana furnace compared to the old clunker! And, we're looking forward to enjoying the new air conditioner once summer rolls around again. Thanks Twintech!

We are very happy with our new furnace. The service was excellent the guys worked 6 hours straight through and there was no mess at all they took the old furnace boxs etc with them they then explained everything to us they were very helpful and pleasant , when we need a new air conditioner we know who to call!

We couldnt have been more impressed with Twintech - from our first service call with Mitch who took the time to thoroughly diagnose the issue with our furnace, to Dave who proposed a well thought out solution to meet our needs and finally Greg and team who acted quickly to install given we had no heat.
We did our due diligence by soliciting quotes from alternate providers and were shocked and disappointed by the aggressive and manipulative tactics used.
Twintech was honest in their approach, detailed in their product knowledge, reasonably priced, diligent in their follow-up and valued our business.
Well done Twintech! You made this a positive experience for us and our new furnace works beautifully!

We recently purchased an Amana high efficiency furnace and humdifier through Twintech. The work was completed very professionally and the quality of the workmanship was high. There was some additional sheet metal work required to complete the installation, which they were able to complete themselves. Overall I am very pleased with the work and would highly recommend Twintech for a furnace replacement.
