• I chose them based upon my uncle's recommendation when they did his HVAC. Their price was more competitive, and I went to school with the owner. They were very easy to work with to replace my furnace & AC system and provided fast turnaround time. So far everything is working great. I just need to make sure it is serviced and maintained properly. Thank you.

• Installation was seamless. Lorenzo arrived on time, was polite and kept the workplace clean. Lorenzo was professional and very thorough in explaining everything. If you are looking for honest HVAC service, this is the company to call.

• Sunday night went on the website and posted a service request. Received a call a 6:45am. By 7:30am Tech was in my basement and diagnosed the problem and made some adjustments and also checked for other issues. He was very through and I felt comfortable having him in our home and servicing our furnace. Tech also suggested their protection program which was a no brainer for future service calls as well as checkups. Very happy my neighbor suggested Hightech.

• Top notch service, courtesy. Furnace went out coldest weekend, other providers could not get anyone out same day. Paul came out and while the end was needing a new furnace, he quickly got the furnace going, showed me what to do in case it went out. Did not get a huge bill, 2 days later, promptly at 8 am, a new furnace was delivered, installed. The 2 young men were very courteous, conscious of keeping the living area clean, laid a cloth down to protect flooring, kept me up to date on what was happening, explained the equipment. Price was very fair, got some good inclusions with the Lennox furnace, good explanations of different types and prices of furnaces. I feel really good about this company and would highly recommend. Great communication all around and I LOVE when people say they will be there at a certain time and they actually are even a few minutes early!!!

• Our heat went out during the 40 below weather today. I called HIgh Tech at 6 am they were here and had my heat back on by 730. Although they cost a bit more I like to think "you get what you pay for." $290.75 for a wire nut... but I couldn't fix it myself so...

• Prompt and professional service! Fair pricing and Aiden does great work. Thank you!

  Stephanie S.★★★★★

• Poor customer service. At initial visit stated the Lennox furnace purchase would give him a $600 tax credit. Now they tell us “up to a $600 credit. So it could be a dollar. They also would not provide the paperwork for the credit to give to the tax preparer. When installed my father wanted anything on paper to say he paid in full. They said they only email or mail. My father doesn’t have email. My dad was willing to give them a price of paper of his own to just write a simple receipt but they wouldn’t do it

  Barb M.★★★★★

• I recently had a great experience with High Tech Heating and Air Conditioning. I needed a new furnace and I received a quote from a couple of places, including High Tech. I chose to move forward with High Tech because they had great customer service, good pricing and they worked quickly to get our new furnace and zoning installed. We've been very pleased with their suggested furnace and how the zoning is operating. They did a great job!!

  Kevin H.★★★★★

• The service I’ve received from High Tech has been outstanding. Josh and his team have always been honest, prompt, and professional. Their pricing is straightforward and competitive. It’s refreshing to do business with a local company like this. I highly recommend them for HVAC installation and service.

  Michael Y.★★★★★

• These gentleman saved me from a horrible experience with another company. We felt like we were taken advantage of elsewhere and the owner came in, taught us what we needed, gave us a fair price, and executed exactly as planned. They were trustworthy, thoughtful and had clear communication. Couldn’t recommend more!!! Great job!

  Brittany S.★★★★★

• George is my technician. He has done an outstanding job, each and every time he has come out and serviced my boiler!

  Chick L.★★★★★

• I called at 8:05 am and they were here by 8:20 am. Lorenzo was excellent. He explained everything he found and replaced what was needed now. He was friendly, professional, and efficient. I took out a service plan with them for the year. Now I will have regular checks on my HAVC. What a relief!

  Mary L.★★★★★

• This was the first time I met Paul. He was enthusiastic, congenial, knowledgeable and helpful.

  Elizabeth M.★★★★★

• This place deserves 10 stars. Today my furnace decided to sleep in and failed to keep us warm. After calling a couple of places I settled on high tech. I was very happy with the response time and Lorenzo, the tech who assisted on site. He was knowledgeable and swift. I highly recommend this place. They got my furnace back on and warming my home in no time at all. These are the people you want working on your furnace. Thank you High Tech and Lorenzo for helping us today.
