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.
Preventing Electrical Overload With Staged Heat
A heating sequencer is a time-delay relay that controls the order and timing in which multiple electric heating elements energize within an electric furnace or heat pump air handler's heat strip package. Rather than energizing every element simultaneously, which would create a massive instantaneous current draw and could trip breakers or overload household electrical service, the sequencer brings elements online one at a time, typically with a delay of 30 seconds to a couple of minutes between stages, spreading out the electrical demand.
Most sequencers use a small internal heater element that warms a bimetal strip, which then physically closes a set of contacts to energize the next stage, an elegant, purely mechanical timing mechanism that doesn't rely on any electronic logic. That mechanical simplicity is also the source of most failures, over years of heating and cooling cycles, the bimetal strip and its contacts can weaken, drift out of proper timing, or the contacts themselves can weld shut, causing a stage to stay energized when it shouldn't or fail to energize when the thermostat calls for it.
We diagnose a failing sequencer by checking its stage timing against the manufacturer's specified delay intervals and testing continuity across each set of contacts both when it should be open and when it should be closed. A sequencer with welded contacts will show a stage energized even with the thermostat satisfied, which can present as elements running continuously and driving up electric bills unexpectedly, while a sequencer with contacts that never close means one or more heating stages simply never comes on, showing up as reduced or absent heat output.
Replacement means matching the sequencer's stage count, contact ratings, and timing specification to the original part, since installing a sequencer with the wrong number of stages or an incompatible timing interval can either underpower the heating system or, in the case of a sequencer that brings elements on too quickly, create the exact overload risk the component is meant to prevent. As with heating elements generally, sequencer service in Georgetown comes up most often on heat pump backup heat strip systems given how much more common heat pumps are here than pure electric furnaces.
