Princeton Air is the right choice for AC installation and repair. We evaluate your current HVAC system or situation, thoroughly explain the available options, and make expert recommendations that fit your specific needs and budget.

Residential Boiler in Brick Basement

Unlike furnaces, which generate heated air, boilers transfer heat or steam heat to generate indoor warmth. New models can be highly efficient, saving you 25-40% on heating bills and lasting 50-75 years if maintained properly.

Furnaces installed in a basement

Your home’s heating needs can account for up to two-thirds of your annual energy bill, so it’s important that we inspect your current furnace to ensure it is not too old, too large or too small for the job it is being asked to do. When a repair is in order, we stand by our quality work and put warranties on any parts we replace. However, with the efficiency of modern furnaces, having a new furnace installed is also a good option as you will begin saving money on heating immediately.

heat pump outside house, part of a hybrid heat pump system

A heat pump, as the name suggests, pumps heat from one location to another location within your home to keep you warmer during wintertime. However, a heat pump can also cool your home in the summertime through the use of a reversing valve and heat exchanger that pushes heat out rather then in.

A typical home's heating and cooling system has too little control, too little comfort, and uses too much energy. Emme Room-by-Room can change that; it provides the control to make your home more comfortable and energy efficient. We won’t simply install the system, we’ll make sure you know how to use it to maximize your comfort and efficiency.
Believe it or not, the #1 reason for heating and cooling systems failures is dirt and grime. A distant second reason is parts failure. That's why during most repairs we determine that regular tune-ups in the past could have prevented the equipment problem being addressed.

Princeton Air is your Middlesex and Mercer County resource for water heater installation & repair. We service all types, makes & models and our master plumber can pinpoint energy savings from a water heater upgrade. Princeton Air's water heater experts ensure your new heater fits your home's needs and your budget.


How do your emergency services and live technicians work?

We have a service technician on-call 24 hours a day, 7 days a week. So you will always speak to a person, not a machine.

If you are calling to schedule a tune-up, we’ll put you on the schedule and confirm the date and time with you the next day during regular business hours.

Do you offer service plans?

Yes. Our Gold service maintenance plan covers a multitude of things that typically go wrong with your heating and AC system and includes annual 12-point heating and cooling tune-ups to maximize performance and longevity. Other benefits include a 15% discount on repairs, Loyalty Credits and more. All this for little more than the cost of an annual tune-up. For more comprehensive coverage, we offer the Platinum plan, which includes all of the Gold member benefits as well as 100% parts coverage!

Is annual maintenance necessary?

Yes! In our area, comfort systems work hard; and just like anything that might be operating virtually non-stop for months on end, a little regular maintenance goes a long way. Think about the car you drive daily -  without the regular maintenance of a tune-up, you lose efficiency (Miles Per Gallon) and money (to replace those gallons used).

Regularly-scheduled & performed tune-ups keep your system working at their peak efficiency, and can extend the life of your equipment by giving our technicians a chance to potentially catch minor problems and signs of wear before they turn into major trouble down the road. An annual tune-up also protects your family/building occupants by helping prevent life & health-threatening conditions from occurring, likecarbon monoxide poisoning for example.
