Founded in 1984, Advanced Heating & Air Conditioning (AHAC) initially operated as Alpha Oil Company until 2000 when it transitioned exclusively to HVAC services. Established by brothers Lou and Danny Roerig, the business flourished under Danny's leadership until his retirement in 2009. The company, now helmed by nephews Louis & Nicholas, continued its upward trajectory by acquiring local HVAC businesses from 2010 to 2012, such as Advance Service Inc. & Ship Mechanical. Serving Warren, Hunterdon, and Middlesex Counties in New Jersey, as well as Lehigh and Northampton Counties in Pennsylvania, AHAC has built a strong reputation for exceptional customer service since its inception. Today, it remains committed to growth and customer satisfaction, adapting to meet the evolving needs of its expanding clientele.

"The tech called ahead to say we will be there in 35 minutes. They came on time! ( Between 10-12) efficient, knowledgeable and did a great job. Canâ t ask for better than that! Thank you!"

We're dedicated to providing our clients with the very best in service, installation, and repair for your heating and cooling needs. We are a locally owned and operated company that values honesty and integrity. We specialize in central A/C and cooling systems, as well as heating and furnace systems. We take pride in the quality of our work, and our commitment to outstanding results. We look forward to building long-term relationships with our clients, and guarantee your satisfaction! Visit us @ RJKMECH.com

"Short version: Professionalism, competency, and integrity is what you can expect from RJK. When our AC stopped working, another company came out to investigate and we were quoted an outrageous temporary repair cost and were advised to replace the whole system. We called RJK and they called back almost immediately. Upon arriving, they advised that a whole system replacement would be unnecessary for starters. But before even doing that, they wanted to have their techs double check that the system was truly in need of any replacement. Turns out the fix was straightforward and within 30 minutes the system was repaired at a fraction of the cost of the original contractor's quoted repair cost and definitely cheaper than a whole new system."

"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!"

"Had to reschedule my original appointment due to their late arrival for the first scheduled time. The office admin was helpful in taking care of that.

Heating and Air Conditioning questions, answered by experts

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

It depends on the number of zones and rooms and how sophisticated the system is. On the low end, a ductless AC system costs $2,000 for one or two zones in one room. Covering two zones for more rooms can cost $6,000 to 8,000. If you want a larger ductless AC system to cover your entire home, multi-zone systems cost upwards of $13,000.

Installing a new AC unit costs $5,850 on average, but costs vary by the make and model, unit size, and unit type. Portable and window AC units cost between $90 and $550, which is significantly less than central or ductless AC systems. You’ll also have to pay for labor.

You should know the main components of an air conditioner: the condenser coils, evaporator coils, drip pan, AC filter, ducts, and refrigerant. Each part plays a key role in the performance and safety of your AC system. When tracking the source of AC issues or odors, it helps to know where to look. Your outdoor unit houses your condenser coils, fan, and compressor. Your indoor unit houses your evaporator coils, drain lines, and filter, and it connects to your ductwork. 

Repairing an AC unit is usually more cost-effective than replacing it, but you should consider the age of your system. Most central AC units last around 15 years, and window units last for between eight and 10 years. If your central AC is more than 10 years old or your window AC is over six years old, you should consider replacing the AC unit rather than repairing it. The repair will fix your issue, but you’ll likely save money in the long run by replacing it rather than repairing it only to replace it a few years later.
