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...
