Properly Performed spring/fall maintenance 2 systems. Replaced all filters checked blower wheels for built up dirt/dust, cleaned flame sensors, cleared inducer ports, tested hot surface igniters, took delta Ts, cleared drain lines, tested safety switches, tested all electrical components, tightened all electrical connections, took running volts/amps, monitored systems operations System overall is in bad shape. System is not cooling properly. Only 9 degrees delta T System is R-22 refrigerant and 19 years old Both capacitors are bad Gave option to get a new system quote. Homeowner approved to only replace the indoor capacitor, add a wet safety switch and add an ss1 safety switch. Work performed properly. Tested system, system is operating ok afterwards. The bare minimum basic repairs to get the system running today.
