for this job, I did an evaluation. Upon arrival, indoor and outdoor were both not running. Opened the air handler and saw the fuse popped. Checked thermostat wiring at the indoor and outdoor unit and all wiring looked good. Noticed the pressure switch wires, resting on copper, and when I checked them, they had burn marks. Fixed up the wiring and moved them out of the way. Put a new fuse in and System stayed on and cooling for over 20 minutes. While the system was running, I noticed the UV bulb was not on. Recommended The homeowners speak with air quality to get a better idea of their options. Homeowners agreed and we scheduled it for October 16 in the afternoon.
