Springtime HVAC Maintenance for a residential customer near Robson Ranch. Upon arrival performed a one system maintenance checking cooling. Checked inside units electrical, mechanical and safety components. Checked filter, capacitor and amp draw on blower. Everything checked out good. Then checked outdoor units pressures, amp draw and capacitor. Found that a snake had wrapped itself around the capacitor causing it to short out. With approval made wire repairs and replaced 80/5 capacitor. Made another wire repair under coil where some rodents had chewed through the wire. System is now operating properly at this time. System is 19yrs old. Recommended that replacement time is coming soon.
