Arrived at the customer’s home to inspect their whole home HVAC system to find the cause of a reported gas smell. Tested heating and cooling from the thermostat. Measured the refrigerant pressures and electrical component readings. Inspected the safety and cleanliness of the system. Checked the 1” air filter. Treated the condensate pump with pan treatment tablets. Left the thermostat in the “off” position. Reported findings to the customer. Based on our findings today, it might be time to think about getting a brand new system.
