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!"
