Drain Line Clog in Winston-Salem — causes and fixes

drain line clog is one of the most common hvac repair callouts in Winston-Salem:

• Typical causes: wear at end of service life, skipped maintenance, environmental stress.
• DIY check first: power, filters, and obvious blockages — safe checks only.
• Pro diagnostic: instruments find the real cause; parts-swapping without diagnosis wastes money.
• Fix or replace: if repair exceeds ~50%% of replacement on an old unit, replacement wins.
