Arrived to remedy an inoperable system. Upon arrival homeowner walked me around to the outside unit. Started testing components of the system. Found that the capacitor is failing. This would cause the compressor to not operate. Without refrigerant flow the system can’t cool. Replaced the capacitor to test system operation. System is operating with a new capacitor installed. Spoke with homeowner about repair solutions. Sold the already done capacitor replacement and signed the homeowner up for the maintenance membership. This way we can come out and perform maintenances and make sure there are not any uncomfortable days in the home. System is operational upon departure.
