The technician David was very friendly, explained what he was doing and answered all of my questions. He invited questions and made sure I understood what was going on with my system. He spent the time to throughly inspect and diagnose my issue; thankfully only having to adjust some things rather than jumping to costly repairs.
He did have some suggested maintenance that sounded reasonable, but I didn't feel pressured at all, giving me time to think before scheduling.
I would highly recommend this company.
