HVAC Components We Repair & Replace, Georgetown TX
Motors & Fans
Diagnose and repair indoor blower motor failures, bearing wear, winding failure, and capacitor issues.
Replace failed indoor blower motors, we stock common motors for Carrier, Trane, Lennox, Goodman, and Rheem.
Lubricate blower motor bearings before they fail, catches motors that squeal before they burn out.
Clean blower wheels coated with dust and debris that reduce airflow and strain the motor.
Repair or replace condenser fan motors, outdoor fan failure causes compressor overheating on Georgetown's 100°F days.
Diagnose and repair outdoor condenser fan motor failures, common cause of AC shutdown in peak summer heat.
Replace cracked, bent, or imbalanced outdoor fan blades causing vibration and motor strain.
Capacitors & Contactors
The #1 Georgetown summer repair. Capacitors overheat and fail in sustained 100°F+ heat, fast, affordable fix.
Test capacitors before replacing, an out-of-spec capacitor causes the same symptoms as a failed compressor.
Replace failed run capacitors on compressors and fan motors, the most common summer AC component failure.
Replace start capacitors that provide the extra torque needed to start compressors on hot days.
Install hard start kits on aging compressors to reduce starting current and extend compressor life.
Replace pitted or failed contactors, the relay that connects power to the compressor and condenser fan.
Replace AC contactors with pitted contacts that cause intermittent power to compressor and outdoor fan.
Compressor Service
Diagnose compressor failures, not every compressor problem requires replacement. We test before recommending replacement.
Compressor replacement with full circuit flush, filter drier, evacuation, and recharge, done correctly to protect the new compressor.
Replace discharge mufflers that reduce compressor noise and protect the refrigerant circuit.
Install crankcase heaters to prevent refrigerant migration into compressor oil during cold Texas nights.
Replace failed high-pressure safety switches that protect compressors from dangerously high discharge pressure.
Replace low-pressure safety switches that prevent compressor damage from loss of refrigerant charge.
Furnace Components
Replace failed high-limit switches that shut furnaces down on overheating, essential safety component.
Replace faulty furnace control boards, we test all connected components first to confirm the board is the failure.
Repair or replace fan control switches that govern blower timing in older furnaces without electronic control boards.
Replace fragile silicon carbide or silicon nitride ignitors, the #1 furnace no-heat repair in Georgetown.
Replace or clean flame sensors that fail to detect the burner flame, causing furnace lockout.
Replace failed gas valves that prevent gas flow to burners, verified diagnosis before replacement.
Replace thermocouples on older standing pilot furnaces that fail to keep the pilot lit.
Replace tripped rollout switches, but also diagnose why flames rolled out, as this indicates a serious underlying condition.
Replace failed draft inducer motors in 80%+ efficiency furnaces, failure causes pressure switch trips and no-heat conditions.
Replace failed heating elements in electric furnaces, test all elements and sequencers before partial replacement.
Replace failed sequencers that stagger heating element startup to prevent circuit overload.
Replace cracked or blocked pilot tubing on older standing pilot furnaces and boilers.
Repair standing pilot assembly issues on older furnaces, thermocouple, pilot orifice, and gas valve.
Replace corroded or leaking main gas shutoff valves at HVAC equipment.
Outdoor Unit & Noise Components
Install compressor sound blankets to reduce outdoor unit noise, particularly useful in Georgetown's zero-lot-line neighborhoods.
Replace deteriorated equipment pads and isolation mounts that transmit vibration through slabs and walls.
Contactors Across Different HVAC Equipment Types
A contactor is an electromechanical switch controlled by a low voltage coil, typically 24 volts from the thermostat circuit, that closes to complete the line voltage circuit powering larger loads like a compressor, condenser fan motor, or in some setups a heat strip contactor bank. Residential split systems most commonly use a single-pole or double-pole contactor rated around 30 to 40 amps, while commercial rooftop units and larger residential package units sometimes use three-pole contactors to switch three-phase power to bigger compressors.
Every contactor wears out the same fundamental way, mechanical and electrical stress at the contact points. Each time the contacts close, a brief arc forms as current jumps the closing gap, and that arcing physically erodes the contact surface over thousands of cycles. Pitted, eroded contacts develop resistance, generate heat, and eventually either fail to make solid contact, causing chatter, buzzing, or intermittent operation, or in less common cases weld themselves together in the closed position, which keeps the load running continuously even when the thermostat is satisfied.
We diagnose contactor problems with a combination of visual inspection for pitting or carbon buildup, a voltage drop test across the closed contacts under actual load, and a check of the 24 volt coil circuit itself, since a contactor that isn't pulling in at all sometimes has a perfectly good set of contacts but a burned out or open coil rather than a mechanical fault. This distinction matters for repair cost and for making sure we're actually fixing the failure rather than replacing a part that wasn't the problem.
On multi-pole and commercial applications, we also check phase balance and confirm the contactor's amperage rating is appropriate for the connected load with some margin, an undersized contactor run near its rated capacity continuously will wear out its contacts significantly faster than one with appropriate headroom. Replacement always matches pole configuration, coil voltage, and amperage rating to the equipment's original specification rather than installing a generic part that happens to fit the mounting bracket.
