For over 24 years, our company has been taking care of the homes of New Jersey residents through our top quality plumbing, HVAC, and electrical services. We are available 24 hours a day, 7 days a week to address even the most mind-boggling issues of your in-home equipment. From repairs, installations, and upgrades, our technicians are known for getting the job done right every time.

"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 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!"

"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"

Heating and Air Conditioning questions, answered by experts

During the summer, it’s best to set your AC to 78 degrees when you’re home and awake, according to the Department of Energy (DOE). For better energy efficiency, raise the temperature slightly to 85 degrees while you’re out of the house. The National Sleep Foundation advises lowering your thermostat to between 60 and 67 degrees when you’re asleep.

Fall and spring are the best times of year to purchase an air conditioner, furnace, or other HVAC components. In fact, by shopping during these periods, you could save 10% to 15% on an AC unit. For HVAC professionals, spring and fall are less busy than summer and winter, when extreme temperatures create an urgent demand for heating and cooling.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.
