"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."



"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!"



"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."

Most Long Island homeowners invest between $8,000-$15,000 for a complete heat pump installation, depending on home size, system capacity, and the type of heat pump. We provide 100% free, no-obligation in-home consultations where we assess your specific needs and give you an unbeatable quote.

Heat pumps are up to 3x more energy-efficient than traditional furnaces and boilers. Most Long Island homeowners see 30-50% reductions in their heating and cooling costs after switching to a heat pump. For a typical 2,000 sq ft home, that translates to $800-$1,500+ in annual savings. Your exact savings depend on your current system, home insulation, and usage patterns - we'll give you a free personalized quote during your free consultation.
You're fully covered. Every installation comes with a 1-year labor warranty in addition to the manufacturer's parts warranty (typically 5-10 years depending on the brand).
