Springtime HVAC Maintenance for a residential customer near Back Elementary School. Came out today on a one system maintenance Checked temp split checked filter cleaned condenser coil checked bearings checked blades checked electrical connections checked contactors checked run capacitors checked Amp draws checked pressures checked ductwork checked insulation levels Found Very low insulation levels cause higher electric bills and the unit to work harder and longer putting more wear and tear on the unit. Bad 45/10 run capacitor (replaced under warranty) No surge protection No IAQ (AIR PURIFIER)
