Real components throughoutDiagnostic Pricing
Real diagnosis, on a meterOutdoor Unit Electrical
Same DayDual Run Capacitor Replacement
The number one reason a South Bay AC quits on a 95 degree afternoon. A swollen or weak run capacitor starves the compressor and fan motor of starting torque. We test microfarads under load, confirm the fault, and install a properly rated replacement. Most calls are same day.
Same DayContactor Replacement
The contactor is the relay that sends 240 volts to your condenser every time the thermostat calls for cooling. Pitted or welded contacts cause no cool, chattering, or a unit that will not shut off. We install the correct pole and coil voltage and verify pull-in.
Same DayHard Start Kit Installation
For an aging compressor that grunts, hums, or trips the breaker on startup, a hard start kit gives it the extra kick to get spinning. It buys time on a tired compressor and takes the strain out of every start.
Same DayDisconnect Box Replacement
The outdoor shutoff that lets us cut power to your condenser safely. A burned or corroded disconnect is a fire risk and a code problem. We install the correct pullout or breaker style and verify it holds voltage under load.
Controls and Safeties
ControlLow Voltage Transformer Replacement
The transformer steps line voltage down to the 24 volts your thermostat and controls actually run on. When it fries, nothing turns on. We confirm secondary output and protect the new one with the correct fuse so it does not cook again.
SafetyHigh Pressure Switch Replacement
A condenser safety that shuts the system down before head pressure climbs into damage territory. Common on dirty coil and overcharge faults in summer heat. We diagnose why it tripped, not just silence the symptom.
SafetyLow Pressure Switch Replacement
The low pressure switch protects the compressor from running on a low or lost charge. When suction pressure drops too far it opens and shuts the compressor down before it overheats and runs dry. We confirm it is tripping for a real reason and is not hiding a slow leak.
Heat PumpReversing Valve Solenoid Coil
On a heat pump, the solenoid coil shifts the reversing valve between heating and cooling. A dead coil leaves you stuck in one mode. Coil only swap, no refrigerant work, usually quick.
Furnace and Air Handler
No HeatFlame Sensor Cleaning or Replacement
A dirty or failing flame sensor makes a furnace light, run a few seconds, then shut off, over and over. Sometimes a clean and verify, sometimes a replacement. Either way we confirm a stable microamp signal before we leave.
Gas ValveSingle-Stage Furnace Gas Valve Replacement
The valve that meters gas to your burners on every call for heat. A failed valve means no ignition or unsafe operation. We replace it, leak check every joint, and verify manifold pressure to spec.
Inducer MotorDraft Inducer Motor Replacement
The inducer pulls combustion gases through the heat exchanger and out the flue. When it seizes or whines, the pressure switch will not close and the furnace locks out. We match the motor and confirm draft after install.
AirflowBlower Motor Replacement, PSC
The indoor motor that moves conditioned air through your ducts. A dead PSC blower means no airflow, no heat, no cool. We confirm the capacitor, amp draw, and that high static pressure is not the real culprit.
AirflowECM Blower Motor Replacement
Variable speed ECM motors are quieter and far more efficient, and they cost more to replace. We confirm the module and program it correctly so you get the airflow profile the system was engineered for, not a generic guess.
Low AirflowBlower Wheel Removal and Cleaning
A blower wheel packed with dust chokes airflow across the whole system, which shows up as weak vents, higher bills, and a furnace or coil that overheats. We pull the wheel, clean every fin, rebalance it, and reinstall so you get full rated airflow again.
ControlFurnace or Air Handler Control Board
The brain that sequences ignition, blower, and safeties. When it fails you get intermittent no heat, error codes, or a dead unit. We read the fault history, confirm the board is the failure and not a symptom, then replace and re-verify the full sequence.
HeatElectric Heat Strip Replacement
The backup or primary electric resistance heat in an air handler or heat pump system. Burned out elements or a tripped limit leave you short on heat. We test each element and the sequencer and confirm correct amp draw on your supply.
No HeatGas Furnace Pressure Switch Replacement
The pressure switch proves the inducer is actually moving combustion air before the furnace lights. A cracked hose, a blocked vent, or a failed switch locks the furnace out on safety. We confirm draft and negative pressure, replace the switch, and verify it proves on every call.
Refrigeration Circuit

Refrigerant Contamination Analysis
Before we recharge a system we can test the refrigerant itself. Using an electronic identifier we check purity and screen for cross contamination, air and non condensables, and the wrong refrigerant mixed in from a past repair. A contaminated charge wrecks compressors and metering devices, so we confirm what is actually in your lines and recommend recovery and a clean charge when it reads off spec.
REFRIGERATION CIRCUITTXV Metering Device Replacement
The thermostatic expansion valve controls how much refrigerant feeds your evaporator. A hunting or stuck TXV causes poor cooling, frosting, or wild superheat. Sealed system job: recover, replace, pull a deep vacuum, weigh in the correct charge.

Suction Line Accumulator Replacement
On heat pumps, the accumulator protects the compressor from liquid floodback. A restricted or leaking accumulator threatens the most expensive part in the system. Full sealed system service with recovery, brazing, evacuation, and recharge.

Liquid Line Filter Drier Replacement
The drier captures moisture and debris in the refrigerant circuit. We replace it any time the system is opened, and on its own when it restricts flow. Recover, braze in the new drier, evacuate, recharge.

Reversing Valve Replacement
The full valve body that flips a heat pump between heating and cooling. A leaking or stuck valve is delicate, heat sensitive brazing work right next to the compressor. Sealed system service done right, not rushed.

Service Valve and Schrader Service
Leaking service ports and valve cores quietly bleed your charge over a season. We replace cores or valves, verify with nitrogen and vacuum, and recharge to spec so you are not refilling the same refrigerant every summer.

Evaporator Coil Replacement
A cased evaporator coil replacement depends on coil match, cabinet access, refrigerant type, and line set condition. We quote it on site after we confirm what your system actually needs. R-454B and R-410A systems are not the same job.
REFRIGERATION CIRCUITRefrigerant Circuit Leak Search
You should not add refrigerant every summer. We pressurize and search the circuit with electronic detection and nitrogen, find the leak, and show you where it is before we quote the repair.
REFRIGERATION CIRCUITRefrigerant Recovery and Recycle
Proper recovery of refrigerant before any sealed system repair, done to EPA standards. We pull it into rated tanks and recycle it, with no venting to the sky.
Thermostats and Comfort Controls
SMART THERMOSTATecobee Thermostat Installation
ecobee, Bryant Housewise, or the smart stat you already bought. We confirm your system has a common wire or add one, set staging and heat pump settings correctly, and tie it into Apple Home, Google Home, or your existing setup. A smart stat wired wrong is just an expensive square on the wall.
Evolution ControlEvolution Connex Control

We install it, wire the communicating bus, and commission the full system so every stage works the way it should, then set up maintenance reminders and remote access.
Compressor Diagnostics & Services
COMPRESSOR DIAGNOSTICSCompressor Diagnostics
The compressor is the heart and the single most expensive component in your system. On an older R-410A unit it is often the moment to weigh repair against replacement honestly. We evaluate age, warranty, refrigerant type, and total system condition before quoting.

System Diagnostics
DiagnosticCondensing Unit Diagnostics
The outdoor unit will not start, trips the breaker, or runs but will not cool. We put a meter on the capacitor, contactor, and compressor and find the actual fault before anyone talks about parts.
DiagnosticFan Coil or Air Handler Diagnostics
No airflow, weak airflow, or the indoor unit will not run. We check the blower, control board, and safeties and tell you what is actually wrong, in plain terms.
DiagnosticPackaged Unit Diagnostics
One cabinet on the roof or the pad, heat and cool in the same box. We diagnose the whole packaged unit, refrigerant side and air side, and lay out exactly what it needs.
DiagnosticCompressor Troubleshooting
Before condemning the most expensive part in the system, we test it. Windings, amp draw, start components, and grounding, so a bad capacitor is never mistaken for a bad compressor.
DiagnosticBreaker and Panel Troubleshooting
When a breaker keeps tripping, the problem is usually the equipment, not the breaker. We inspect the panel, check the breaker and the bus bar for heat and corrosion, and measure the actual load, so we fix the cause instead of resetting it again.
Maintenance
MaintenanceCondensate Line Clean Out
A clogged condensate line backs up water and can trip your safety switch or stain a ceiling. We clear the line, flush it, and confirm it drains so it does not overflow in the next heat wave.
MaintenanceEvaporator Coil Cleaning
A dirty evaporator coil chokes airflow and cripples cooling. We clean the coil with the right foaming cleaner, rinse it, and clear the drain, restoring capacity without tearing the system apart. When a coil is too far gone we pull it and clean it out of the cabinet.
Deep CleanBlower Wheel and Condenser Coil Restoration
A full system restoration for a neglected unit. We pull and deep clean the blower wheel and housing, then clean the condenser coil front to back. Airflow and heat transfer come back, and the system runs cooler, quieter, and cheaper.
