Capacitor & Contactor Replacement
Is Your A/C Making a Humming Noise But Not Starting? These two small, inexpensive components are among the most common points of failure in any HVAC system. A bad capacitor or contactor can stop your cooling completely, mimicking more serious problems. We keep them in stock for same-day repairs to get your comfort back fast.
01.
Dual-Run Capacitor Testing & Replacement
The capacitor provides the necessary jolt of electricity to start the compressor and fan motors and keeps them running smoothly. We test capacitance and resistance to diagnose weak or failed capacitors and replace them with correctly matched, high-temperature-rated units.
02.
Contactor (Relay) Inspection & Replacement
The contactor is the heavy-duty switch that sends power to the compressor and condenser fan. We check for pitted, burned, or welded contacts, weak coils, and proper 24-volt signal from the thermostat. We replace faulty units with durable, amp-rated replacements.
03.
Preventive Maintenance & Hard-Start Kit Installation
During tune-ups, we proactively test these components for early signs of failure. For older systems or those in areas with power fluctuations, we can install a hard-start kit to reduce strain on the compressor and capacitors, extending their life.
04.
Complete Electrical Safety Check
When replacing these parts, we inspect all related wiring for brittleness or corrosion, verify tight electrical connections at the disconnect and breaker panel, and ensure the system is grounded properly for safe operation.
