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.

"Excellent service . Stayed and troubleshooted the system until it got back into operation."

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!"

FAQs for boiler repair projects in Dover, NJ

The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.

Yes, most states require plumbers to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations.

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.

The average cost to hire a plumber is around $100 an hour but can vary between $45 and $200 an hour depending on the plumber’s experience and the repair that you need. It’s also important to note that these prices can go up on holidays, and emergency plumber rates average $150 per hour, in addition to a flat-rate trip fee of $100 to $350
