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!"

Water Heaters questions, answered by experts

Boilers are used mainly for central heating, and water heaters are used for ordinary household water use. In fact, a conventional boiler works best if your home already has a water heater system in place. Sometimes a boiler can be combined with indirect water heaters. But there are also premade combination boiler heaters.

Not all homes are required by code to have water heater expansion tanks, though some cities, like Los Angeles, do. Sometimes, municipalities will require a code that asks homeowners to install an expansion tank if their water heater is on a closed system. A closed system setup without an expansion tank can place unnecessary stress on appliances and shorten their lifespan.

Going from a tank to a tankless water heater is one of the most effective ways to lower your utility bills. The switch also frees up more space and ensures a consistent hot water supply, as the water is heated on an as-needed basis. It costs between $5,400 and $7,400 to install a new tankless water heater. Most installation companies will also help dispose of your old water tank.

The standard copper wire gauge to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.

Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.
