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.
Reading the Diagnostic Codes on a Furnace Control Board
The integrated furnace control, often just called the control board, is the central electronic brain that sequences your furnace's entire ignition and safety process: energizing the draft inducer, confirming the pressure switch closes, powering the hot surface ignitor or spark igniter, opening the gas valve at the right moment, monitoring the flame sensor signal to confirm ignition, and finally bringing on the blower motor after an appropriate delay to avoid blowing cold air. Most boards communicate their diagnosis through a blinking LED, and the blink pattern, a specific count of flashes, corresponds to a documented fault code in the manufacturer's troubleshooting chart mounted inside the furnace's access panel.
Reading that blink code correctly is the starting point of any control board diagnosis, but it's important to understand the code often points to a symptom detected by the board rather than definitively confirming the board itself has failed. A code indicating flame sensor failure, for instance, could mean a genuinely dirty flame sensor, a bad connection, or, less commonly, a board that's misreading a perfectly good sensor signal, we verify the actual component before condemning the board.
Control boards fail from a handful of common causes: power surges, which Georgetown sees periodically from summer thunderstorm activity across Williamson County, moisture intrusion in humid crawlspace or attic installations, and simple age-related component failure on the board's relays and circuit traces after years of thermal cycling. A board with a failed relay might successfully run the inducer and ignitor but fail to energize the blower, or vice versa, producing symptoms that look confusing until you understand which specific relay function has actually failed.
When we diagnose a suspected board failure, we test the board's output voltages at each relevant terminal against manufacturer specification with the furnace attempting to run through its normal sequence, rather than replacing the board on the strength of a blink code alone. Replacement requires matching board specifications exactly, terminal configuration, timing parameters, and compatibility with your specific furnace model, a mismatched universal board can sometimes physically fit but run incorrect timing sequences that create new problems rather than solving the original one.
