Upon arrival tech was informed atm room would get hot. Tech confirmed that room does not have a stand alone system but it attached to teller counter system. Thermostat for area was set for heat only at 70 degrees reading 73 indoor. After reviewing history more previous thermostat setting was auto with lower temp. Tech recommended setting back to auto and lowering temperature. Informed customer that if issue continues we could install exhaust fan in room with temp sensor to pull extra heat out if room reaches certain temperature. Customer stated they would like a quote for that option.
