This is our second time using this company. The first time they installed a drain pan, cleared lines and made some adjustments to the drainage lines. This time, they refilled the Freon. The tech recommended we start getting ready to replace our 20 year old unit, and also didn't think it was worthwhile to try to find refrigerant leaks given the age of the system. That's a matter of opinion, but the service was prompt and courteous and done right as far as I can tell.
