We had a get together at our house Friday evening and 30 minutes into the event our AC stopped working. We've worked with RK HVAC in the past so we decided to call them once again. Initially, they attempted to help us over the phone per our request. Once that did not work, they came out within the hour and found a Freon leak and fixed it immediately. We're aware our system is quite old and needs to be replaced in moving forward. Once that time comes, we'll be sure to call RK HVAC. Thanks for the great service!
