Just experienced an amazing service call from Dave S. #1618. I have been struggling with understanding and appreciating things to be done with my furnace and AC and was anxiously waiting for a service technician to come over. Dave came in on time and started his process extraordinarily. As against simply walking to the furnace room and thermostat he started by understanding what were my expectations from the service call. After I explained my issues, challenges, need to know technical stuff etc, DAVE immediately understood that my I truly needed a proper orientation. He then went about logically explaining each aspect of the furnace and AC, maintenance , how can I save energy, how should I set my temperature, how do I periodically clean, change for weather etc. He then completed his task of cleaning, checking for readings etc, On a request of mine he voluntarily called his office and set up immediate appointments to get some additional things to be done. I am writing this review because I have so far only been experiencing technicians who come in a rush, complete their job, rush out as fast while having very little patience for home owners who ask a lot of "silly" simple questions. Dave was a refreshing difference. Truly very impressed and wish there were more professionals like DAVE #1618 who enjoy what they do. Best Regards. Dr. G Shermon.
