Without AC with 90+ F temperature, Burkholders was able to fit me in on the same day I called as a first-time customer. I happily accepted the after hours service charge. A very professional and knowledgeable technician, Dan, diagnosed a leaking and corroded evaporator coil and low R22 refrigerant level. He re-charged the system back to full function and rightly advised that several replacement options were in the near future, including R410A compatibility issues.
