My technician was Keyon. I thought he was very professional, thorough, and forthcoming about repair options, maintenance, and ways to prolong the life of door openers. He finished the job quickly, and the doors are operating beautifully. I also thought the cost of it all was fair and comparable to that of other service work I've had done in the past (i.e. hvac, plumbing, electrical, etc.). I'm glad I contacted Precision, and I would definitely recommend them to other prospective customers.
