"Garden state water heat company came to my house to swap replace water heater. They replaced it and left a faulty leak that they caused during the installation. I asked them to fix it. They promised to do so but now they are not responding to my texts. They gave me a quote for 750 but changed the amount to 1050 because my water heater is two feet above ground. The water heater was a warranty replacement. I just wanted them to fix the leak they had caused. I am so disappointed. "

Alpine is a fourth-generation, family-owned business proudly serving Central NJ as the region’s premier air conditioning and heating company for more than five decades. We specialize in HVAC repairs, system replacements, and ongoing maintenance. Custom HVAC Solutions: We design systems specifically for your home’s size and your financial goals, with robust rebates, reduced utility bills and 0% financing available for up to 7 years. Honest, Skilled Technicians: Our licensed, fully trained technicians are focused on fixing the problem, not upselling you on unnecessary equipment or services. Seasonal Tune-Ups & Protection Plans: Keep your system running efficiently with seasonal tune-ups and take advantage of our service contracts for year-round peace of mind. Beyond Heating & Cooling: We also install hot water heaters, indoor air quality solutions like humidifiers and air cleaners, as well as generators and sump pumps to keep your home protected in emergencies.

"Alpine installed my Trane heating and air conditioning system 18 years ago. At that time, I decided to purchase a service contract that would allow me to receive 2x a year cleaning and inspection. It was the best investment I could have made! Today their technician Troy came to conduct the preseason service on my air conditioner. My appointment was for 10am and Troy arrived promptly at 10am! During the course of the inspection, Troy discovered that the dual run capacitor was leaking oil. He showed me the part and suggested that it could be a problem down the road. Since the system is 18 years old, I wasn't surprised that there might be a worn part that would need to be replaced. Luckily, he had the part on hand and was able to do the repair right away. Because I had the service contract, I received a discount on the parts and labor which was greatly appreciated. I'm so glad that I called Alpine all those years ago. I highly recommend them for your heating and cooling needs!"

When you need help with your heating, ventilation and air conditioning, you don’t want to hear that your technician is stuck in traffic. You won’t hear that excuse from us. We’re based in Brooklyn, at Sheepshead Bay road - in an office, not a phone drop or a postal address. It gives us quick access to many of our customers. But we also have workstations in Staten Island and Long Island. This way, our techs can quickly help you, whether you have an emergency or a routine call. They can rapidly fan out across Manhattan, Queens, Brooklyn and Long Island, ready to install mini-splits and portable AC units, clean chimneys, service residential and commercial HVAC systems, solve your radiant heat problem or get your furnace running more effectively. Our techs are experienced in all sorts of HVAC installation and repair, from heat pump systems and oil furnaces to air conditioner compressors and ac units. How we began As veterans of the industry for more than 10 years, we formed the company in Brooklyn in June 2016 with just one van and one technician. Fortunately, satisfied customers have rewarded us with many referrals and now we have seven vans and 15 people on our team, including office staff. We’re very proud and very grateful for our success. The team leader is Greg. He oversees all three locations and keeps us organized, making sure we respond to calls and we don’t leave until the customer is satisfied. Our techs are experienced, licensed and insured. We can help you, whether you want a new heat pump, a boiler repair, clean air ducts or a commercial HVAC overhaul.

"I called Premier HVAC Services for a routine check-up, and they never showed up. After waiting 3 hours, they rescheduled for a week later without any apologies. Completely unprofessional and unreliable. I wouldn’t trust them with my HVAC needs."
