Showed up on time for my regular 6 month HVAC health check. I explained to the technician that the smart thermostat was complaining about high humidity, which he quickly diagnosed and fixed (by siliconing the hole in wall behind the thermostat). He then performed a quick and thorough check of the HVAC system. Kudos to Raul, who was a very friendly technician that answered my questions clearly.
