How refreshing!!! I will definitely call them back next year when I will need service. And no charge for the check up! B“

“We have been Sweezy’s customers for almost 30 years. We have been getting our oil and furnace serviced in that time. Our sons needed a new central air conditioning system so we gave Sweezy’s a call. I spoke with Michael McBride. Michael came out and assessed the old system and recommended the replacement system we would need. The price was very good and we were very happy because it was being backed by a company we’ve known and trusted for years. Pedro and his team came out to install the new system on one of the hottest days of the summer. They were neat and worked very fast, gone in about 4/5 hours. The system is working on perfectly and keeping the house like an icebox. We’re very happy with Sweezy’s and highly recommend.“

“Excellent service !!!!! came within 24 hours just like they said
very professional“

“My hot water heater sprung a leak on the afternoon of July 3, meaning that I was not going to have a repairman come until Monday. At 8 am Monday morning I called a firm with whom I have transacted in the past with excellent results, Sampson Plumbing and Heating. Their two plumbers were here by noon. Not only did they fix my water heater, but they repaired another half dozen problems with my plumbing that I had put off for the last year. Their work was fabulous, everything installed as I asked for, everything worked perfectly. Nice fellows with excellent personalities, I really felt that they were prioritizing my interests while they were here. The were neat, creative with their solutions, and the cleaned up after themselves when finished. I could not be happier about the work performed by Sampson Plumbing and Heating, especially that their prices were very reasonable as well. If you need a plumber in the Stony Brook area, I recommend Sampson Plumbing and Heating as your first call, they always have exceeded my expectations.

“I can’t say enough great things about this entire experience. From the very beginning, Jon came to our home, took the time to understand exactly what we were looking for, and guided us through every option with professionalism, patience, and genuine care. He made the whole process easy and stress-free and was always available to answer questions and keep us informed.

We had a mini-split system installed in our basement and central air installed throughout the upstairs of our home, and the results have exceeded every expectation. The quality of the work and attention to detail were outstanding.

On Day 1, field supervisor Angelo was absolutely phenomenal. His leadership, attention to detail, and commitment to quality were evident from the moment he arrived. He kept everything organized, made sure the work was done to the highest standard, and treated our home with incredible respect. His professionalism and positive attitude immediately gave us confidence that we were in excellent hands.

On Day 2, field supervisor Will continued that same level of excellence. He was knowledgeable, personable, and went above and beyond to ensure every last detail was perfect. He took the time to explain everything, answered all of our questions, and made sure we were completely satisfied before the job was finished. His dedication to customer service and pride in his work truly stood out.

From Jon’s outstanding guidance to Angelo’s exceptional leadership and Will’s meticulous follow-through, every part of this experience exceeded our expectations. The entire team demonstrated professionalism, expertise, and a level of customer care that is hard to find today. The installation was seamless, the craftsmanship was top-notch, and the final product looks and performs beautifully.

If you’re considering a mini-split system, central air installation, or any HVAC project, this is the team to trust. We couldn’t be happier with our experience and would recommend them without hesitation. Five stars simply aren’t enough!“

“Had to call early this morning for service for my central air conditioning. To tell you the truth, due to the heat wave that is on its way, I figured it might be a long wait. So I called and left a message and within 1/2 hour Dominick called me back. He said that he would have someone at my place in about an hour. He was as good as his word, and the service man came and took care of everything. My main problem was downstairs was not cooling as it should be, and it seemed to be struggling. A part needed to be replaced, and some Freon added. I forget the name of my service man, but I want to mention how polite, efficient and understanding he was. He really went above and beyond , but actually that has always been the way anytime I call for service and of course, several years ago when they installed my entire HVAC system. Couldn’t be more pleased. So basically, my primary adjectives for describing Absolute HVAC servicing are: Friendly, polite, efficient, knowledgeable, and timely!“
