We repair and calibrate thermostats for accurate temperature control, ensuring your AC runs efficiently and maintains consistent comfort
We repair faulty compressors to restore full AC functionality, improve efficiency, and extend the life of your cooling system
If your AC hums but fails to start, your outdoor fan spins slowly or not at all, or your system starts intermittently and then runs normally, a failed capacitor is the most likely cause. Capacitors store and release the electrical charge your compressor and fan motors need to start and maintain correct operating speed. Houston's sustained high ambient temperatures accelerate capacitor dielectric breakdown faster than in almost any other city, making capacitor failure the single most common electrical repair on Houston AC systems every summer. A failed capacitor left unaddressed forces motors to attempt startup without adequate electrical support, drawing locked rotor current that burns out windings within minutes of repeated attempts.
If your outdoor unit fails to start when the thermostat calls for cooling, runs continuously without shutting off, or you hear chattering or buzzing from your outdoor electrical compartment, your contactor has failed or is failing. The contactor is the high voltage switching relay that connects and disconnects power to your compressor and condenser fan motor with every cooling cycle. In Houston's heat contactors perform far more switching cycles annually than in seasonal climates and the contact points erode, pit, and eventually weld together or fail to close entirely. A contactor stuck closed causes continuous uncontrolled compressor operation that leads directly to compressor failure.
If your AC system behaves erratically, loses power intermittently, trips breakers without an obvious cause, or your technician has been unable to identify a specific component failure to explain your system's symptoms, wiring faults or failed electrical connections may be the underlying cause. Houston's heat causes wire insulation to become brittle and crack over time, vibration from years of compressor and fan motor operation loosens terminal connections, rodents nesting in outdoor units damage wiring, and moisture intrusion causes corrosion at electrical terminals that creates resistance, voltage drops, and intermittent faults that are difficult to diagnose without systematic electrical testing.
If your AC system displays error codes, operates unpredictably, ignores thermostat commands, runs components in incorrect sequences, or your technician has confirmed all individual components are functioning correctly but the system still misbehaves, your control board has likely failed. The control board is the electronic brain of your air handler that coordinates every operational sequence from startup through shutdown. Control board failures in Houston are accelerated by power surges from Houston's severe storm activity, voltage fluctuations during peak grid demand in summer, and the accumulated thermal stress of years of operation in Houston's heat cycling environment.
If your AC system loses power entirely, trips the circuit breaker at the electrical panel repeatedly, or the disconnect box at your outdoor unit shows signs of burning, arcing, or heat damage, you have an electrical supply problem that goes beyond the AC system itself and affects the safety of your entire electrical installation. Disconnect box failures and breaker problems in Houston AC systems are caused by contactors drawing excessive amperage due to compressor problems, fuses rated incorrectly for the system's load requirements, disconnect boxes that have degraded from years of outdoor Houston weather exposure, or circuit breakers that have weakened from repeated trips and no longer hold reliably at their rated amperage.
Your technician begins with a complete inspection of every electrical component in your AC system including the disconnect box and fusing, contactor and capacitors in the outdoor unit, control board and low voltage wiring in the air handler, all high voltage wiring connections at every terminal throughout the system, and the circuit breaker serving the AC system at your main electrical panel. Every visible sign of electrical damage including burn marks, melted insulation, corrosion at terminals, physical damage to components, and heat discoloration is documented before any testing begins.
Your technician tests every electrical component using a digital multimeter to measure voltage supply at every key point in the system, verify correct resistance across all wiring runs and motor windings, and identify shorts to ground in motors and wiring. A capacitor meter tests every capacitor against its rated microfarad value. A clamp meter measures amperage draw on the compressor and all fan motors against their nameplate ratings. Low voltage control circuit continuity is verified from the thermostat through to every controlled component to identify any signal breaks in the control wiring.
Your technician identifies not just the failed electrical component but every factor that caused or contributed to the failure. Whether the cause is Houston's ambient heat accelerating capacitor and contactor degradation, a compressor drawing excessive amperage due to developing mechanical problems that is burning electrical components prematurely, voltage supply irregularities from your electrical panel stressing sensitive control components, moisture or rodent damage to wiring, or accumulated switching cycles from Houston's near year-round operation exhausting component design life, understanding every contributing factor ensures the replacement components are not subjected to the same conditions that caused the original failures.
Before any electrical repair work begins you receive a clear written quote covering every replacement component, all labor involved, and any additional electrical corrections identified during testing such as disconnect fuse upgrades or wiring repairs. There are no hidden fees and no pressure to approve work beyond what your system genuinely requires. You see every cost upfront and approve all repairs before your technician begins work on your system.
Your technician replaces every failed or out-of-specification electrical component with correctly rated replacements matched to your system's specific voltage, amperage, and configuration requirements. This includes replacing capacitors with correctly rated microfarad and voltage specifications, installing new contactors rated for your compressor and fan motor loads, repairing or replacing damaged wiring with correctly rated conductors and properly terminated connections, replacing failed control boards with compatible units, upgrading disconnect boxes and fusing where undersized or damaged components are identified, and verifying correct low voltage control circuit operation from thermostat to every controlled component throughout the system.
After every electrical repair your system is tested through a complete startup and operating cycle to verify correct voltage at all key supply points, amperage draw on every motor within nameplate rated limits, stable contactor engagement and release without chattering or arcing, correct control board sequencing through startup and shutdown, and confirmed temperature differential in the 16 to 22 degree Fahrenheit range at supply vents confirming the system is producing correct cooling output with all electrical components functioning safely within their design parameters.

Yes. A failed capacitor that causes repeated locked rotor starting attempts burns out compressor windings within minutes. A contactor stuck closed causes continuous uncontrolled compressor operation leading to overheating and failure. Wiring faults that create voltage drops force the compressor to draw higher amperage to compensate, accelerating winding deterioration. In Houston's heat any electrical fault that stresses the compressor progresses to permanent compressor damage faster than in cooler climates.

We are available Monday through Friday from 7am to 10pm, Saturday from 8am to 10pm, and Sunday from 7am to 9pm. Most Houston customers receive a technician within 2 to 4 hours of calling during our available service hours with most electrical component repairs completed within the same visit.
Houston's extreme summer heat is the primary reason AC electrical components fail faster here than in most other cities. Capacitor dielectric material, contactor coil insulation, and control board components all degrade at accelerated rates under sustained high ambient temperatures. Houston's near year-round cooling season also means these components perform far more operational cycles annually than in seasonal climates, compressing their effective service life significantly compared to cooler regions.
No. Repeatedly resetting a breaker that keeps tripping means your AC system is drawing more current than the circuit is rated for due to a compressor fault, electrical short, wiring problem, or failing component that has not yet been identified. Every reset attempt without diagnosing the cause risks permanent compressor damage, wiring damage from sustained overcurrent, and in serious cases an electrical fire hazard. Call for professional diagnosis before resetting a repeatedly tripping breaker.
AC control boards in Houston fail most commonly due to power surges from Houston's frequent severe thunderstorm activity, voltage fluctuations during peak summer grid demand, moisture intrusion into the air handler cabinet during Houston's high humidity conditions, accumulated thermal stress from years of operation in high ambient temperatures, and physical damage from rodents accessing the air handler cabinet. Whole-home surge protection significantly reduces control board failure risk from storm-related power events.
Yes. We are available for AC electrical component repair Saturday from 8am to 10pm and Sunday from 7am to 9pm. Evening appointments run until 10pm Monday through Friday. An electrical fault in your AC system during Houston's summer heat is not something that can safely wait until the following week because continued operation with an undiagnosed electrical fault risks compressor damage and creates potential electrical safety hazards in your home or business.
