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 100ยฐF 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 100ยฐF+ 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.
The Capacitor That Only Works for a Split Second
A start capacitor is fundamentally different from a run capacitor in both its job and how it's wired into the circuit. Rather than staying continuously connected while a motor operates, a start capacitor is wired through a current-sensing or voltage-sensing relay that connects it only during the brief moment a compressor motor is starting, delivering a strong, short burst of additional torque to help the motor overcome initial mechanical and pressure resistance, and then the relay disconnects the start capacitor entirely within a fraction of a second once the motor reaches normal running speed.
Because it's engaged so briefly, a start capacitor is built with a much higher microfarad rating than a comparable run capacitor, but it's also not rated for continuous duty, and this is exactly why a failing relay is the most common cause of start capacitor failure. If the relay's contacts stick closed or fail to disconnect properly after startup, the start capacitor stays energized well beyond its intended split-second window, and the sustained current and heat quickly cause it to overheat, bulge, and fail, sometimes within a single extended run cycle.
Start capacitors typically show up as part of a hard start kit added to a compressor that was originally designed to start on just a run capacitor alone, providing extra assistance for an aging compressor, a system with long refrigerant line runs, or a household experiencing voltage sag on startup. When we diagnose a failed start capacitor, we always test the associated relay alongside it, since replacing a burnt-out start capacitor without also verifying or replacing a relay that's sticking closed just sets up the new capacitor to fail the same way within a short time.
Replacement requires matching microfarad rating and voltage rating exactly, and confirming the relay is correctly sized and functioning to disconnect the capacitor promptly after each start cycle. Because start capacitors experience such a different duty cycle than run capacitors, brief, high-intensity bursts rather than continuous moderate load, they fail in a genuinely different pattern, and understanding that distinction is part of correctly diagnosing why one failed in the first place rather than just swapping the part and hoping it doesn't happen again.
