We moved into a new home and had no idea about the heating system. The technician. Dominic, took time to show us the system and made good recommendations. Now 6 months later we had Maurice Gaines technician, come do a maintenance check on our air conditioner. He found a problem and fixed it immediately. Now the unit will run smoother and is in good working order We now feel we have good knowledge of the workings and look forward to working with Princeton Air for our future needs.

A-1!!! Compared to other HVAC companies, Dominic provided a full explanation of problems with steam boiler, along with photographs- appreciate the “education” and recommendations. Christian and team replaced the boiler today. Team of three worked efficiently and kept me informed of their progress. Nice guys, too. Very happy with PA.

Ryan G. arrived to perform regular A/C maintenance and determined the drain pipes leading from the condensor coil into the sump were clogged and in need of replacement. He performed the work in timely fashion at a reasonable price and also took the time to provide some useful advice. This is the second time Ryan has performed service in my home and I find him to be a helpful and conscientious professional.
