Upon arrival the homeowner informed me that the indoor fan has been running but not blowing cool air. Ownee noticed this happened for the first time 3 weeks ago but has not used the cooling side of the unit since then. Followed the path of 24 volts starting from the outside back to the inside. When arriving to the thermostat,the system began cooling. Jumpered wires y, g, o to r together to keep system running. Checked refrigerant levels and deltas. Everything checked while system was running came back within normal limits. Recommended soft start kit due to over amperage on startup, recommended drain strip due to dirty drain lines, recommended new thermostat due to thermostat being the last thing checked on the 24 v path, recommended membership for discounts and warranties. Owner declined all recommendations at this time and stated they had to talk with their wife before spending mone on anything aside from the evaluation. Left system running on 72 cool.
