Beware of their bad business practices, 9/17/2013

O'Callaghan Heating and Air Conditioning is not a reputable company. During a routine maintenance call, a new service technician allowed more than 5 pounds of Freon to escape. Instead of admitting... his mistake, the company said my unit was leaking Freon and had to be replaced. Another company replaced the missing Freon, checked for leaks several weeks later, and found nothing wrong with the system. Now, the owner, Dennis Roach will not respond to my requests for a refund of $450 it took to replace the Freon. Do not do business with this company.


High quality HVAC service, 8/26/2013

I had a $10,000 system installed by them a year ago and it went very smoothly. They provided excellent service with the system over the next year, without any issues or problems. The service calls... were 100% on time, unlike others that give you a huge 4-6 hour window to show up. The Trane systems aren't cheap, but they're very high quality. O'Callaghan gave us an awesome upgrade in our home over the old junky construction grade compressor and furnace we had. thanks!
