Thermostat & Controls Services, Georgetown TX
Thermostat Installation & Service
Install any thermostat, standard, programmable, or smart, with proper wiring, configuration, and testing.
Replace faulty or outdated thermostats. We identify compatibility requirements before recommending equipment.
Recalibrate thermostats reading inaccurately, a 2-3°F offset causes significant comfort and efficiency problems in Georgetown's heat.
Determine if the thermostat or the system is the cause of HVAC problems, the thermostat is rarely the actual culprit.
Relocate thermostats away from heat sources, drafts, or direct sunlight that cause inaccurate temperature readings.
Install a common wire for smart thermostats that require continuous 24V power, without it, smart thermostats often malfunction.
Full smart thermostat setup including wiring, app configuration, scheduling, and compatibility verification.
Optimize thermostat response settings, anticipator adjustment, and stage sequencing for your specific system.
HVAC Electrical Diagnostics & Repair
Systematic low-voltage and line-voltage electrical diagnosis, find faults without replacing working components.
Repair damaged, corroded, or incorrectly wired HVAC control and power circuits.
Diagnose and repair HVAC power supply issues, breakers, disconnects, and line-voltage components.
Correct overcurrent or undersized circuit conditions causing tripped breakers or component damage.
Recover HVAC systems stuck in lockout, error states, or post-power-surge conditions.
Trace and repair 24V control circuit faults, shorts, opens, and incorrect wiring between thermostat and equipment.
Repair or replace outdoor AC disconnect boxes, fuses, and weatherhead connections.
Replace deteriorated flexible conduit and wiring connections at outdoor AC units.
HVAC Control Components
Diagnose and repair HVAC control system failures including boards, relays, and communication wiring.
Full system calibration, thermostat, controls, and equipment operating parameters aligned and verified.
Calibrate system staging, fan delays, and operating behavior for your specific comfort and efficiency goals.
Calibrate control signals between thermostat and equipment, staging, modulation, and communication signals.
Replace failed 24V control transformers, the power supply for the entire low-voltage control circuit.
Replace failed relay boards that control equipment staging and multi-zone operation.
Install safety disconnect switches for code compliance and service safety on HVAC equipment.
Replace aquastat controls on hydronic and boiler systems that regulate water temperature.
Install and configure zone control panels for multi-zone HVAC systems.
Install outdoor temperature sensors for weather-compensating controls and smart thermostat systems.
How We Handle Whip and Conduit Replacement
The electrical whip is the short section of flexible, liquid-tight conduit that runs from the outdoor disconnect box to the condensing unit's electrical access panel. It carries 208 to 240 volt line power to the compressor and outdoor fan motor, and it is built with a bend to absorb the small amount of vibration a condenser produces during startup and normal operation. In Georgetown, this conduit sits outside year round, exposed to direct sun for most of the day on south and west facing pads, and to UV breakdown that makes the plastic jacket brittle over time.
The most common failure we see is UV cracking of the outer jacket, which lets in moisture at the fittings. Once water tracks down inside the whip, it reaches the wire connections at the disconnect or the unit's low voltage and line voltage lugs, causing corrosion, resistance heating, and eventually a burned connector or a nuisance breaker trip. A second common failure is squirrel or rodent damage where conduit runs along a fence line or through mulch beds. We also see whips that were never properly strain relieved at installation, so years of wind and lawn equipment vibration work the conductors loose at the terminal screws.
Our repair process starts with a visual and continuity check of the whip and both end connections with power locked out at the disconnect. If the jacket is cracked, brittle, or shows scorching at either end, we replace the entire whip assembly rather than patching it, since a compromised jacket usually means moisture has already reached the conductors even if damage isn't visible yet. We size the new whip to match the unit's minimum circuit ampacity listed on the nameplate, torque every terminal to the compressor manufacturer's spec, and reseal both conduit connectors with proper liquid tight fittings so they meet the same weather sealing standard as the original installation.
Georgetown's summer storm season brings frequent high wind events that put repeated stress on outdoor conduit runs, and homes near mature oak trees see more debris impact on exposed whips than open lots. We also check the conduit's bend radius during replacement, a whip installed with too tight a bend work hardens the conductors inside and shortens its service life regardless of jacket condition. This is line voltage work, so it should only be performed with the disconnect open and locked, and by a licensed technician familiar with the unit manufacturer's terminal torque specifications.
