Today I performed a routine maintenance on your American standard heat pump split system. I checked all the electrical connections on both the indoor and outdoor equipment, flushed the drain line, changed the air filter, checked the capacitor ratings and checked the system operations when the maintenance was completed. Your system is over 20 years old and is rusted badly on both the indoor and outdoor unit. Your emergency pan under the unit in the attic is rusted badly and needs to be replaced. Everything seems to be running as good as it can in the condition it’s in. .
