Expert Commercial Services for Reliable Business Comfort

I needed a new HVAC system. From the beginning of the process through the finished installation the McAllister Service Co team was very professional and answered all my questions to my satisfaction. The installation went smoothly and the team did a thorough clean up of the equipment installation locations. I want to say a special thanks to Zeus and Michael D my maintenance reps, Jason L my system and installation project manager, and Joe D, my installation team manager and his team on 6/8.

Princeton Air Conditioning replaced my 25 year old central air conditioner. The sales person was very knowledgeable, made sure I was getting the correct size unit, explained the available options and got a quote out very quickly. They were very competitive on price and did an excellent job installing the unit. I am planning on having them provide all maintenance on the unit. I highly recommend Princeton Air Conditioning.

They are a great company, hvac techs where totally professional,

Ryan G is a knowledgeable, professional and has great customer service.

Martique was 5+! Extremely knowledgeable and thorough. I do have a significant concern about one of the inspection findings related to the evaporator coils. Will address directly with the company.

Helped with an electrical issue. Fair and affordable.

Great service and follow up. Honest answers

Dominic was very professional and installed my new Nest Thermostat in. He showed me some features and mage sure I had the app set up on my I- Phone. Dominic forgot to put the door back on my furnace but returned and put it securely back on.

I was very happy with the central air conditioning system Princeton Air installed for me. They were very prompt in getting a quote to me, were very competitive and did an excellent job with the installation. I plan on using them for all maintenance on the unit and highly recommend them.

I appreciate how responsive Princeton Air is. Tom did all he could to fix our system.

They did a great job. Nelson was very knowledgeable and professional.

MOST RECENT June 2026:
Weltman has been purchased by Princeton Air. They have been really great. A seamless transition on the customer side. Eric was just here to put in a new anti-scaling system and a pressure relief valve for the house. Very happy!

UPDATE:
Now in our home for almost 8 years and Weltman has never disappointed! Chris L came today and was completely professional and quick for our yearly inspection of our furnace before the cold winter! It’s great to know they keep great notes and, almost, know more about our system than we do!

Weltman will always make it right if something is wrong. They will also get to you ASAP! We have been customers since we bought our home 3 years ago and have been completely satisfied!

Teck was knowledgeable and courteous

The technician Alfredo is great

I was recommended Princeton Air by a friend and I’m very happy that I was. I had a hvac and furnace system that was 25 years old and in dire need of replacement.
Chris from the company came out very promptly and did a full review, taking the time to take me through the different options. From there we reached an agreement and within one week the team came out and did a full dual zone system replacement.
I was blown away by the professionalism and indeed sheer hard work of the installation team. They arrived at 08.30am and finished at 8.30pm working tirelessly to complete the job in one day. A huge thank you to Princeton air, Chris and the install team -Jorge Vizueta, John Jaramillo, Juan Torres and Jhonny Anacona for a really cool air conditioning experience. Thank you!

The repair man, Dominic came out this morning to inspect our AC system. He was extremely knowledgeable, incredibly kind, and explained things very well. I work in construction and can tell you that Dominic is one of the best I’ve seen in years. Princeton air is very lucky to have him as an employee as he is SUCH AN ASSET to your company.

I also want to give a special thanks to Leah the customer service representative I spoke to. Also extremely kind and helpful. I have had the worst two weeks of my life and two strangers taking the time to kind made my heart smile. Thanks again Leah and Dominic.

Norman was great!!! He has come before. His advice and work were great!!!! Unfortunately Princeton Air, formerly a family run business, has been bought by a large corporate group, and we have chosen not to use them any longer

The technician was thorough, knowledgeable and professional. He also called for an ETA and was punctual.

I wanted to say a BIG Thank you to Princeton Air and Jesus C for coming to our rescue when AC in our house wasn’t working (despite it working fine 3 weeks ago). My daughter and her friends arrived on Friday afternoon for a girls weekend. Even though the compressor unit outside was running, no air was coming through the vents inside the house. After talking her through a few things over the phone (none of which resolved the issue), I called Princeton Air.
Despite it being already 5pm on Friday, they dispatched a technician who arrived within an hour. Jesus C called me several times to keep me updated about the repair. Within 45 min, the air was blowing COLD!!
I highly recommend this company. I am beyond grateful for the prompt and professional service we received.

Thanks so much for the EXCELLENT service from Norman. He was very knowledgeable and so friendly. Really nice guy. Thank you Norman and thank you Princeton Air.

Just to let you know everything here is fine. Norman was wonderful!! Helpful and very friendly. Thank you Norman and thank you Princeton Air.

Great service , Ryan was fantastic

We recently had a new AC unit installed by Princeton Air and had a great experience from start to finish. The installation went smoothly, the team was professional, knowledgeable, and respectful of our home, and we are very satisfied with the quality of the work.
We did have one minor issue after the installation, but Dominic McGinley responded quickly and took care of it right away. His prompt service and commitment to making sure everything was working properly really stood out.
Overall, we’re very happy with Princeton Air and would highly recommend them to anyone looking for HVAC services.

Dillion was very pleasant ,He informed me what he was going to do what Needed to be done and afterwards Everything that was completed
