Completed first time homecare maintenance. Homeowner stated that the bill for electricity spiked up. Noticed that the return ducts was undersized. The zone damper for the first zone was not fully opening. The bypass was not functioning either. We checked the outside unit the dual capacitor was below manufacture specs on here side. Homeowner decided to swap the bypass and zone damper. Also added a 10” duct to the return plenum because it needed 300 CFM. Homeowner also paid homecare upfront. Collected payment and signatures. System was functioning at departure.
