A1 Heating and Air Conditioning Inc 11 Hulse Road, Setauket- East Setauket, NY 11733

"Ricardo is always so helpful when coming to my hospital for any heating issues. We are greatly appreciative for their help and assistance. Melissa is great with communication on the phone and always gets us on the schedule right away."

"Competent, courteous, efficient and knowledgeable. The entire A1 Team - Ricardo, Christian and the Men who performed our air conditioning installation exhibited a high degree of professionalism and superior customer service. Our home is important to us and the new air conditioning system is a significant investment. The Team's approach to us, our home, and our concerns—and the extent of their knowledge—put us at ease. Ricardo's expertise and mastery of air-cooling principles and technology is impressive; he answered all of our questions and provided new information. Our discussion with Gary (Owner) was also key to our confidence in the company—a long-time businessman and former mechanical technician. We were pleased with his knowledge, understanding and appreciated his willingness to connect with us personally. We're grateful to have found such a skilled, dedicated, and responsible company. Thank you A1!"

"A1 is the best service provider on Long Island. I’ve researched dozens and worked with several companies over the years. No one comes close to their professionalism, service, and value. Their scheduling service for example meant that I knew when they were coming. The job was done in a timely manner. The employees were courteous and clean. Beyond the service I received I would go a step further and recommend A1 as a great company to work for as well. Employees are trusted and respected."

"We recently used A1 for air conditioning installation in our school. Ricardo was extremely accommodating and did all the installation on the weekend and after school hours so they didn’t interrupt our school day. All of the workers were professional and neat. The price was also very reasonable and much lower than other companies we received quotes from. Highly recommended."

"I recently had an issue with my 9-year-old Navien boiler, which was damaged due to internal leaks. Thankfully, the plumber went above and beyond. Not only did they promptly identify the issue, but they also called the company and guided me through the warranty process. Thanks to their expertise and assistance, I ended up with a brand new boiler hassle-free. I wholeheartedly recommend this plumber for their professionalism and exceptional service. 100% satisfaction guaranteed."
