I have the Platinum Program for my air conditioning unit and my furnace, through Randazzo Heating And Cooling. They installed these units, and also come out to the house a few times during the year to check it and make sure they're fine, and working properly. If there are any issues, they resolve it. They are always flexible with scheduling those service appointments, and the guys that come to service our units are always nice and polite. We have been with the company about 7 years, and we will continue to use them through our service contract.
