Dave was very pleasant to deal with and Twintech responded quickly when our furnace needed to be replaced ASAP. Installation was done on time and the crew were neat and tidy. We now have a great furnace that suits the needs of our family.

When your furnace kicks in over the holidays and you're not sure where to turn.. I'm so thankful that this company returned my phone call. I appreciated their transparency and clarity which allowed me to make an informed decision. With various quotes thrown at you, it can be difficult to make the right decision and trust the solutions offered by different companies. TwinTech spoke the truth and delivered on their word. Neat, timely and clean service; the peace of mind I needed during a very cold holiday season. I highly recommend them!
Feb 1, 2021
Pulling a old unit out and installing a modern heating system! Required drilling holes in the wall for the newer pipes. We went from 70% (I am willing to bet it was far less due to lack of maintenance and just old) to 96% newer . It now feels warmer and more pressure and we use to run extra heaters and feel as though they are not necessary!
Feb 1, 2021
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!

They had the best price and did a great job on the installation. Recommend them to anyone.

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!

The crew from sales to installation was very professional and had great attention to detail

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!

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.
