"If I could, I would give this horrible service provider a 0.0! I scheduled a plumbing appointment on a call, which was confirmed via multiple texts the day prior to the appt. Then had an employee go to the location during the 4 hour window they specified and wait for the plumber. On the day of the appt, 1 hour into the time window someone calls and says, sorry we’re not going to go because we only do residential plumbing. This was a surprise, as it was communicated to them that this was a business when I had set up the appt. So, I decided to speak with a manager. After spending over an hour of being bounced around from one dept to another, asking for a manager, they never connected me to one and their dispatcher had the audacity to say “sorry for your inconvenience, but you’ll just have to find someone else.” WOW! The hoops they make you jump through and the rudeness is not worth the hassle. I would definitely recommend you find a different plumbing pro for your project!"

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.

"I’ve been an Alpine customer since 1975. Alpine is a remarkable example of a small business model (regardless of industry) that other businesses would be smart to emulate. It’s astounding, how they continue to flourish given accelerated market threats, market opportunities and government regulations. They also figured out how to stay more than relevant even with rapidly changing technologies, suppliers and price, along with the active consolidation of small companies by the behemoths (e.g. public utilities, big-box). Their secret sauce is their founding principles of authentic commitment to customer perceived value and continuing to grow/train their exceptional technical service folks. Congratulations on achieving and sustaining your founding vision. Well done! --------------------------My Alpine History------------------------------------------------ I moved to NJ in 1975 and began an immediate search for the best services providers (e.g. MDs, HVACs, Auto Mechanics). I have extremely high standards in terms of quality, price, customer focus and ethics. Furthermore, because of my professional background as a senior consultant for IBM, I am very detailed and fact oriented. All houses in my development had been built 15 years earlier with ducts for forced-air heating only. I brought 3 specialist contractors to evaluate installing AC using the existing ducts. Art Staloff (the owner of Alpine Refrigeration, founded 1972) was the only contractor whose assessment seemed credible and reasonably priced and then proved to be absolutely true. Over a 44 span, I’ve exclusively used Alpine for all my HVAC needs and most recently a whole-house generator. I’ve also taken advantage of their well-priced and high-value pre-season service agreements Paul Raskas East Brunswick, NJ"

"Worst service I’ve ever have experienced. They wanted to sell me the product, never told me that there was an early termination fee and another penalty for an initial offer they gave me. Had double charges every month, once for the oil they provided (which they never told me they were going to provide before coming. They just came without my knowledge and then I find a high amount bill) and another for an “automatic payment” for 500 that they never could explain. The didn’t even fix this issue and it kept happening every month even after I cancelled the service. Then having to call them is a hastié for the refund of the 500. Stay away of this company"

"I asked them for help fixing a job that another HVAC company had completed. There was an obvious issue, they uncovered it, and advised me to go back to the original person. When I expressed doubt that the original person could fix it, they said they had my best interest in possibly having the service under warranty. I said I just wanted them to fix it and was willing to pay, but they refused to do it. I ended up with no heat overnight and having to pay another professional the same amount to fix it. I?m not sure why after I was authorizing the repair that they didn?t want to do it."

Boiler Repair questions, answered by experts

It is usually worth it to repair your HVAC system instead of replacing it. However, one exception is if your system is reaching the end of its life—usually 15 to 25 years. Otherwise, repairs will cost an average of $350, and a full HVAC replacement would total $7,500 in most cases, or between $5,000 and $22,000, depending on the type of system. A reputable HVAC repair company can inspect your system and let you know if replacing it would be more cost-effective.

There are several types of home radiators, and the most common are steam heat radiators, electric radiators, and dual-fuel radiators. Steam heat radiators are connected to a boiler. Electric radiators can operate without being connected to anything else—they just need an electrical outlet. If you have a dual-fuel radiator, you’ll see a valve at the bottom of the system with a wire coming out of it and going into a wall. These are often your towel radiators in the bathroom. The type of radiator you have will impact how you turn it on.

Regular maintenance includes annual inspections, filter changes, and checking for leaks or pressure inconsistencies to improve efficiency and longevity.

A furnace takes in cool air, heats it through the burner and heat exchanger, and sends the air on its way to warm your home. A boiler is a pressurized vessel that produces hot water or steam to heat the home and provide hot water. A boiler may or may not work together with a furnace.

HVAC quotes may be negotiable. It’s important to be upfront about what you need, your budget, and your expectations. However, your contractor must suggest repairs or the system they think is best for you, and those things may not be negotiable. So, when can you negotiate an HVAC quote? When installing a new system, you may not need to replace ductwork or install specialty items such as whole-home air purifiers. If your contractor is bidding on those items or others you don’t need or want, ask them for a quote on only the equipment and services you need.
