I have been a customer with Weltman for years and here recently, Weltman was taken over by Princeton Air. I made an appointment for my seasonal checkup for my air conditioning unit.. Technician Ryan Gobel was dispatched to my home.He came in and was very professional, knowledgeable and tentative to my concerns and he answered all my questions regarding my system..I wanted to change my two zone system back to it's original state as I didn't have 2 units, I have one unit with dual zones. I set up an appointment to have that done. Ryan came back for this appointment to do the work and he had another gentleman he was training by the name of Dayone Brack. They both came in and went right to work. As Ryan changed parts, he showed me the old parts explained the reasons why the part was defective and explained the insulation of the new parts all while training Dayone. After all the work was done, he tested the system to ensure everything was working up to standard. He cleaned up his work area and left my home nice and neat just as he found it. Both Ryan and Dayone even put on shoe coverings without me having to ask. Over all my experience was a good one and I will request Ryan again when it's time for my seasonal maintaince. Keep up the good work Ryan and continue to keep up the excellent customer service. Dayone, good luck with your training and keep up the good work.
Fantastic communication and service quality, they do great work. I have used them for many jobs and would recommend them as the best HVAC vendor in central NJ.
I had an issue with my air conditioner give a call to Princeton air they was very professional and fast respond, love their service
Great job. Worked efficiently. Work area clean
Alberto was great. Super friendly and fixed the problem in no time.
Had a new minisplit system placed. From the initial quote to actual instalation it was very organized and professional. All appointment times given were honored and during the 2 hour windows they would text updates narrowing the actual times for their arrival. Instalation was done in 1 day, for us, and the installers and electrician were very professional during the install and wiring. They were also great about cleaning up after themselves. We just had the three days of 90 plus degrees, this past week, and all our units performed as expected. Incredibly within the 1 degree as promised. This will be my first year not carrying up, and then down again, from our basement the 6 window units I had to place to cool our home. That alone was worth the cost, which was signicant but also very reasonable considering the quality of the outdoor and indoor units used and complexity of the install, in home built in 1947. Thank you Princeton Air!!
Princeton Air technician came out to check out A/C that stopped working yesterday. He went down, checked and diagnosed the problem, and had the air back on within 10 minutes. I recommend this company.

Joe was super thorough and very knowledgeable during his inspection of the commercial HVAC units. I felt informed and well equipped as a potential future tenant. Highly recommend!
As a second generation McAllister, now, Princeton customer in Atlantic County, I am pleased to report another successful system installation. This year it is a state-of-the-art Combi water heater and HVAC installation at the seashore. Scheduling occurred with "military precision." The bevy of workers and equipment arrived on time — all friendly and informative. By the second day all done, manual provided & questions answered. Always a good crew to have onsite. Company was also very helpful in scheduling my A/C system maintenance at the same time as all the other work beating the start of the summer season.
Service man Ryan is always very professional and thorough and takes the time to explain whatโ€™s going on with our heating and air-conditioning system.
I waited all day three times for the repairman. I am going to change my service provider.
Technician was very good.
Prompt, polite, informative, professional, thorough
Ryan G arrived promptly to my home to see why my air conditioning unit wasn't working. He clearly explained upfront the charges for diagnosing the problem. He quickly discovered the source of the issue and showed me pictures of the clogged a/c pipe and explained the work he would be doing. After the work was completed, he showed me how much debris he pumped out of the pipe and explained the charges which were very reasonable. I was thoroughly happy with the service that Ryan G provided. His descriptions and instructions were very clear. I would highly recommend Ryan G. & Princeton Air to all !
Our tech Dominic was Great!!
Princeton Air did a great job installing my new Carrier Furnace and A/C system. Devin and Woody were really polite and professional. Great experience and thorough cleanup. Also, Joe was a really professional electrician, and a really nice guy.
Iโ€™m very happy with my new system.
Thank you Princeton Air.
Latrell and Norman two very hard workers ran into situations replacing a compressor on our air conditioning unit but kept us informed as to their progress. It was frustrating for them on hottest day of year but they kept their professional and customer service attitudes up in a pleasant manner. Two excellent maintenance service repair professionals.
Excelente servicio, el tรฉcnico Dominic muy profesional y muy amable. 100% recomendable
Ali was great! We have a very confusing system here at the office and Ali went over and above and let us know what happened, what he did to fix it, and an action plan going forward. He also provided with solutions and recommendations to corporate in his work order, providing me with peace of mind that our company and the people who need to know what is going on.
Back to normal
They sent someone out when my Central Air died in the middle of a heatwave; it turned out to be frozen so they had to return after it thawed, but everything was timely and I felt well taken care of. Dispatchers, office staff and my tech, Cruise, were all excellent. I was up and running by noon!
Very knowledgeable and professional Navien tech.
Maurice Gaines was friendly, helpful, knowledgeable and efficient! I've used Princeton Air's services a few times now and it's always been a good experience.
Latrelle did an excellent job
I had issues with my A/C unit that would sporadically not turn on and wouldnโ€™t be able to reach the desired set temperature. I had a service contract with the utility company , who I called out 3 times to fix the issue and each time they couldnโ€™t find anything wrong. This time I called Princeton Air, was able to book online and they came out the next day. Ryan came to my house and listened to the entire history of my A/C issues. He was able to troubleshoot and quickly found there was a wiring issue which he was able to correct that day. He educated me on my unit and explained in detail to me everything he did along the way. Thank you Ryan, you are very talented in your skill.
Maurice was terrific and solved the problem very quickly. I highly recommend Princeton Air.

happy mother with two happy children

Emergency Service for All Types of Cooling Systems

Throughout West Windsor’s diverse neighborhoods, from Princeton Junction to Dutch Neck, homeowners rely on an equally varied range of cooling systems.

At Princeton Air, our technicians are trained to diagnose and repair all major cooling system types throughout West Windsor. When your system stops working, you can trust our team to identify the issue quickly and restore emergency cooling service with the right solution for your equipment.

Most West Windsor homes depend on central AC for their primary cooling needs. Refrigerant issues, electrical faults, compressor failures, or frozen coils can cause system breakdowns. These problems quickly make the entire house uncomfortable. Our technicians bring experience with all major central AC brands and configurations to West Windsor, working fast to get whole-home cooling back online.

Both heating and cooling depend on heat pumps in West Windsor homes, with summer cooling performance relying on precise refrigerant cycles and mechanical operation. Component wear, electrical faults, or refrigerant loss can disrupt this balance. Performance drops sharply. The nuances of heat pump operation are well understood by Princeton Air technicians, who can identify and fix these problems efficiently.

Additions, finished basements, and spaces without existing ductwork in West Windsor homes increasingly rely on mini-split systems. Depending on the configuration, a failed indoor air handler or outdoor unit can impact just one room or compromise the entire system. Our team accurately diagnoses ductless issues in West Windsor and restores the quiet, efficient cooling performance these systems deliver.

Zoned systems deliver targeted temperature control to different areas of your West Windsor home. But malfunctioning dampers, thermostats, or control panels create hot spots and rooms that refuse to cool properly. Our technicians evaluate the complete system to pinpoint exactly where the breakdown occurs, then restore balanced comfort throughout every room.

Most cooling emergencies are the result of small issues that went undetected until the system finally gave out.

The Princeton Air Comfort Club is our annual maintenance program designed to catch those issues before they become emergencies. Members receive scheduled seasonal inspections and tune-ups that keep cooling systems running efficiently and reliably through the hottest months.

Regular professional maintenance improves performance, extends equipment life, and significantly reduces the likelihood of a breakdown on the worst possible day. For homeowners who want fewer emergencies and lower long-term costs, Comfort Club membership is a smart investment.

Frequently Asked Questions

What counts as an AC emergency in West Windsor, NJ?

A cooling system failure becomes an emergency when your West Windsor home can’t maintain comfortable temperatures during hot weather and indoor temperatures start climbing. This covers units that refuse to start, systems running without producing cool air, strange noises or odors coming from the equipment, or units that shut down before reaching your thermostat setting. West Windsor’s humid summer conditions make these breakdowns particularly uncomfortable. Getting emergency AC repair in West Windsor quickly prevents minor issues from turning into major system damage.

What steps should I take while waiting for a technician?

Start by confirming your thermostat is set to “cool” with the temperature below your current room temperature, then check if your air filter is clogged or if a circuit breaker has tripped. Pull blinds and curtains closed on sunny windows to reduce heat buildup. Skip using the oven, dryer, or other heat-producing appliances while you wait for emergency AC repair in West Windsor. Turn the system off immediately if you hear strange sounds or see ice formation on the unit, and keep it off until our technician can safely diagnose the problem.

Why is my AC running continuously without cooling the house?

Your AC runs constantly but doesn’t cool your West Windsor home for several reasons. The problem typically stems from low refrigerant, a dirty or frozen evaporator coil, compressor failure, or an undersized system struggling with New Jersey’s summer heat. Leaky ductwork can also cause this issue by allowing cooled air to escape before reaching your living areas. Our technicians will diagnose the exact problem through a complete system inspection and get your cooling back to normal operation.

How does West Windsor’s humidity affect air conditioning systems?

High humidity levels in West Windsor create extra demands on air conditioning systems beyond simple temperature control. Your AC must pull moisture from the air while cooling. This forces the compressor and refrigerant system to work much harder than they would in drier climates. This additional strain speeds up wear on aging components and makes your home feel warmer than the actual temperature reading, leading many homeowners to push their systems harder to achieve the same comfort level.

Is it worth repairing an older air conditioner, or should I replace it?

Three key factors determine if repair or replacement makes sense: your system’s age, what’s actually broken, and how much the fix costs compared to a new unit. Systems over 10-15 years old with major component failures like compressor problems often cost more to repair than they’re worth. This is especially true when repair bills hit half the price of replacement equipment. West Windsor’s humid summers put extra stress on aging AC components, so older systems here tend to develop multiple issues once major problems start appearing.
