ProCore are the BEST. I would highly recommend to anyone who needs fast, professional, courteous and very skilled repair for air conditioning in NYC. When my Mitsubishi central air conditioning system in my Manhattan apartment (Chelsea) abruptly stopped working in the middle of a heat wave the night before the July 4th holiday I was worried I would wait days (even weeks) to find a qualified repair. I called six different NYC HVAC repair companies and either couldn't reach anyone or was told that their first appointment was two weeks away. When I called ProCore (on the recommendation of a friend) I was immediately connected to a technician who listened to the situation and told me he would be there the next morning "first thing". At 8:30am two technicians arrived and immediately got to work. They solved the problem, fixed the system, and even made some minor adjustments to make my system more energy efficient. They were friendly, courteous, professional and obviously very good at their job. Their price was very reasonable - to the point where I gave both of them a little extra to thank them for their excellent work and for coming on a holiday early morning. My apartment immediately started cooling down and the system is working better than ever. Just to illustrate the professionalism: both technicians put "covers" on their shoes that they brought with them so they didn't bring any dirt on to my floor (without even being asked to do that). This is a FIVE STAR business and I will highly recommend them to anyone who needs excellent HVAC / Air Conditioning services in NYC. In a city where there are many options - ProCore is the best of the best and I highly recommend them. read more
