"Benjamin and his entire crew were the best! From the start I was provided with personal, thorough and professional inspection of my HVAC unit. When I decided that I wanted to do an entire replacement of my system, Benjamin provided multiple options to fit my needs. He always responded to my questions and their crew showed up on time each day they were scheduled to work. My project was tough as I live in an older townhome, but Benjamin and his team worked hard to make sure everything was done right. He truly cares about his clients, and the quality of work that he does. If you need any type of work done on your AC or HVAC unit - this is your guy! "

"I highly recommend this company. Penguin heating & Air was very quick to respond to my request, fast text reply, sent them pics, they replied with a quote, which was way lower than anyone else on this site, or even our regular guy that we normally use, we scheduled an appointment for the very next day, which was today, he also finished the job the same day! David did a very good job, very professional. Despite a terrible rainy day, he got the job done. When he was done he walked me through with exactly what he did. He also quoted me for a service on an existing unit and his quote was almost $200 less than what our regular guy charges us... We will absolutely be using this company again."

"Air Tech was great. I would HIGHLY recommend. I initially had 2 other companies besides Air Tech come out for a replacement estimate. Price wise Air Tech was right in the middle but were doing a lot more than the other 2 quotes I got. For example they were changing the copper refrigeration lines, which the other 2 weren’t going to do. When I called the other 2 companies to add the lines in there was going to be an additional $1500-$2000 charge. I’m very pleased with this the work that was done by Air Tech"
