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.
How a Combination Gas Valve Actually Works
The gas valve on a modern furnace is a combination valve, meaning it houses several functions in a single assembly: redundant safety valve seats that must both open for gas to flow, a pressure regulator that controls the gas pressure delivered to the manifold and burners, and, on many furnaces, the built-in electronics that time gas flow relative to the ignitor or pilot signal. The valve opens on a 24 volt signal from the control board once the entire ignition sequence, inducer proving draft, ignitor reaching temperature or pilot flame confirmed, has been satisfied.
Gas valve failure generally falls into one of two categories, and they carry very different implications. A valve stuck closed, or one whose internal coil has failed electrically, simply won't allow gas flow, resulting in a no-heat call where the furnace goes through its ignition attempt, inducer runs, ignitor glows, but no flame ever establishes since no gas is reaching the burners. A valve stuck partially or fully open, by contrast, is a genuine safety concern, since it can allow gas to continue flowing even when it shouldn't, and this failure mode requires immediate attention rather than routine scheduling.
Diagnosis starts with verifying the valve is receiving its 24 volt signal from the board at the correct point in the ignition sequence, since a valve that never gets the signal isn't actually a valve problem at all, it's an upstream issue with the board, pressure switch, or wiring. If the valve is confirmed to be receiving signal but not opening, or opening incompletely, we test manifold gas pressure with a manometer against the manufacturer's specified pressure, both with the valve fully open and, on two-stage valves, at both low and high fire settings.
Replacement of a gas valve is significant enough work that it always includes a post-installation leak test on all connections using both a manometer pressure decay test and a bubble solution check on every joint, and a combustion analysis to confirm the furnace is burning cleanly and safely once the new valve is regulating gas pressure correctly. This isn't a component we ever treat as a routine, low-attention swap given what's at stake if a gas connection isn't sealed properly.
