Common Duncanville AC Failures
Capacitor failure (most common, easiest repair)
Symptoms: Outdoor unit hums but fan doesn't spin, or compressor doesn't engage. Clicking sound at startup. Common on systems 7-12+ years old.
Repair cost: typically $150-$350 with same-day parts availability
Contactor failure
Symptoms: Outdoor unit completely silent, no fan, no compressor. Indoor air handler may still run.
Repair cost: typically $200-$400
Refrigerant leak
Symptoms: System runs but produces no cool air, cools intermittently, indoor coil freeze-up.
Repair cost: $400-$1,500 depending on leak location and refrigerant type. R-22 systems (pre-2010 equipment) are particularly expensive to recharge.
Compressor failure
Symptoms: Outdoor unit hums but no cooling. Major repair on systems past year 12-15.
Repair cost: $1,800-$4,500 — at this cost level, replacement consideration becomes appropriate. See Repair vs Replace AC Dallas TX.
Indoor air handler / blower motor failure
Symptoms: System cycles but no airflow at registers, or weak airflow throughout home.
Repair cost: $400-$1,200 depending on motor type
Drain pan / condensate issues
Symptoms: Float switch activates and shuts off AC, water accumulating around indoor air handler.
Repair cost: $200-$500 for cleaning and drain line repair
Duncanville Housing Stock Context
Duncanville's residential housing stock concentrates in 1960s-1980s ranch and traditional homes — typically 1,400-2,200 sq ft with original or first-replacement ductwork. Common failure patterns for this housing stock:
- R-22 equipment — many homes still running pre-2010 systems with R-22 refrigerant. Replacement refrigerant cost has risen significantly; refrigerant-related repairs increasingly tilt toward replacement decision.
- Aging single-stage equipment — past expected service life on most systems installed before 2015
- Duct system degradation — attic ductwork showing insulation breakdown and air leakage

After the Repair
Most AC failures are predictable. Annual maintenance catches roughly 70% of failures before they become emergency events. Capacitor testing, contactor inspection, refrigerant pressure trending, and drain line cleaning during annual service prevent most peak-summer breakdowns.
