Our aging A/C unit kept tripping the breaker, so we called Ron Jon. Even though it was the middle of the summer, they were able to send out a technician early the next day. He thoroughly checked out the system and determined that the time had come to replace the whole compressor/condenser unit. He was able to quote us a (quite reasonable) price right away and - because of a cancellation - they were able to install the unit the same day. All the employees (in the office and the ones that came to our house) were knowledgeable and courteous. Great experience overall!
