Testimonials
Christopher Walsh
"I had an excellent experience working with Advanced Tech HVAC for my CAC replacement install. Rob and Zach were very thorough in answering all of my questions and were very responsive whenever I texted. The price they quoted was extremely competitive and didn't change once the job started... They were clean, neat and courtesy."
Katerina Kyriakakis
"We are so pleased with the work done by Advanced Tech HVAC! From start to finish, the experience was excellent. They responded quickly to our initial inquiry and after they visited the following day, we were provided with an estimate within 24 hours. The work was completed promptly, professionally and with great attention to cleanliness... We couldn't be happier with the service and would absolutely recommend them!"
Nicholas DeCeglia
"I got recommended this company from my brother. They completed an installation for him this summer. Called them on a Tuesday and Rob showed up on that Thursday, I had a quote in my hand before they left. Scheduled the work for them to install three 5-ton units for me. Job was completed in 2 days. They were early, good communicators, and super clean. All of their guys had boot coverings which my wife loved. Highly recommend this company for any installation."
