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.

"We had used Alpine previously for small system repairs and were satisfied with their service. This was a big project, however, and we obtained several quotes. Their price was in the middle and we felt more confident using them, based on past experience. The crew of three showed up right on time. They were very professional. Wore masks the entire time, due to the pandemic and used shoe covers and drop cloths to minimize tracking dirt into the house. They worked well together and willingly answered all my questions. They cleaned up the debris before they left and explained the operation of the system thermostat, answering all questions. And the furnace even worked after they left! Won't be able to comment on the AC unit for several months. Could not have asked for better service."
