During Powell & Turner’s HVAC maintenance tune-up, we check the indoor and outdoor components of your system, and although an issue with your system could occur at any time, a maintenance tune-up helps identify any parts that are starting to fail. Our maintenance tune-ups include an evaluation/inspection of your HVAC system, as well as replacing 1″ air filters, replacing thermostat batteries (if needed), cleaning the CAD cell eye or flame sensor (during a heating maintenance on furnaces), replacing the oil nozzle & oil filter (during the heating maintenance on oil furnaces), cleaning the indoor and outdoor coil with cleaner (during a cooling maintenance), and flushing and treating the drain line with bleach tablets (during a cooling maintenance). Please call our office at 410-636-7614 and we can discuss our 2 different Maintenance Plan options that we offer!
