Accurate Conditioning is a small, but not tiny personally owned company started in 2004. This company has been built on its reputation and referrals from customers to customer, not big time advertising. So don't call the big name guys and get robbed call the small guy not looking to take advantage of you. Accurate conditioning has a small fee which includes the first 1/2 hour of labor and trip charge. Our prices are very competitive to all the local small company's.

"Accurate Conditioning was extremely professional, fair, and knowledgeable. Everything was explained thoroughly and we are very happy with the finished product. All work was done in a clean and timely manner, and I would highly recommend this company for any HVAC needs. Thank you!!!"

"My wall gas heater one day just went out. I called several companies and was told they didn’t service that type of heater. One company gave me the number for Angi. The guys with Whitestone came immediately and suggested I replace it because the problem was the pilot. I bought a new heater and they installed it in just a couple of days later. I feel that they were very knowledgeable, diligent and pleasant. It’s working great."

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.

"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!"

Arctic Air Conditioning is a family run business that has served New Jersey since 1977. We specialize in residential and commercial Air Conditioning, Heating, Humidification, and indoor air quality. Our other services include Plumbing, Electrical, and Garage Doors. Our philosophy is to provide top of the line equipment with the best installation and service available in the industry. We are an award winning Lennox Dealer and Home Depot Service Provider.

"I found Arctic Air Conditioning via the NJ Clean Energy website as they are a certified contractor for the NJ Clean Energy Home Performance Program. I researched the program before hand and knew that the energy efficient rebates (up to 4K) and financing (0% for 7 years) would be perfect for me. Arctic thoroughly accessed my home, this included examining the current equipment, calculating the size/area of the house, and took the time to discuss any issues I was currently having. The technician explained everything, answered all my questions, and let me know about the Home Performance program and how equipment has improved over the years. What I really like was that they didn't just want to replace my system, they took additional time to test my existing system to see how everything was working - this critical step showed that I was not getting enough return air for the system to run properly. Very quickly after the assessment I received their proposal which included a few different levels of equipment to match different budget levels. I also got quotes from two other contractors, but neither offered options, they seemed to offer standard packages regardless of the size of house. I chose to install a 96% efficient two stage HVAC system with 3 ton AC, a power vented 50 gallon high efficient water heater, an interactive digital thermostat with tons of settings/schedules/reporting, and adding additional insulation in the attic along with sealing any gaps/spaces in the attic floor. They also suggested an additional return to ease the system. Scheduling was effortless, and the workers arrived on time to begin the install. All the workers were excellent, they were nice, worked clean, installed everything perfectly, and they completed the job fast! I am very cautious with people working on my house, nobody cares as much about my home as me, so I was very relieved that these guys were total professionals. The new system is so quiet, looks good, and works perfectly. In the end, I am very glad I found Arctic, this project went as smooth as possible. I look forward to using Arctic to service my equipment in the future and have great confidence that they will continue to impress me... there is a reason that this company has been around for 41 years!"

Plumbing, HVAC, and electrical systems make your house livable. One minor issue with any of these systems can put your home at a standstill. In case you find yourself in this unfortunate situation, know that you can count on Gold Medal Service. 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. We also provide upfront pricing with a full description of the service before commencing work to avoid any surprises down the line.

"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!"

FAQs for heating and air conditioning service projects in Monmouth Junction, NJ

Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.

While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.  

The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.

Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations. 

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
