Fault Diagnosis & Fix
Get a measured diagnosis and a clear repair-vs-replacement answer before any parts are ordered.
Common Repair Pitfalls
Skipping proper diagnostics leads to parts replaced on guesswork, faults that return, and money spent twice.
Replacing a capacitor or contactor without measuring amp draw first means the real fault, often a failing compressor, goes undetected.
Voltage and amp draw tests at each component confirm which part has failed before anything is ordered or replaced.
Topping up refrigerant without locating the leak means the charge drops again within weeks and coil damage can follow.
High- and low-side refrigerant pressure readings identify whether a leak exists and where before any refrigerant work is done.
Colorado’s cold winters stress reversing valves hard; a valve stuck in one mode is often misread as a thermostat or refrigerant fault.
Error code reading combined with a mode-switch test isolates a reversing valve fault from other causes before repair work starts.
Committing to a costly compressor repair on an older unit without comparing it to replacement value can mean spending more than the system is worth.
When repair cost approaches replacement value, you receive a written side-by-side comparison so the decision is yours to make with full information.
Repair Scope
From a single failed capacitor to a refrigerant leak or reversing valve replacement, the scope spans all common failure points.
Pressure testing locates the leak in the line set or coil, then the leak is sealed and the system recharged to spec.
Amp draw and pressure tests confirm whether the compressor is the fault before any replacement decision is made.
A stuck or leaking reversing valve is confirmed by mode-switch testing, then replaced to restore full heating and cooling operation.
Electrical tests identify a failed capacitor or worn contactor, two of the most common causes of a unit that runs but won’t reach temperature.
Dirty evaporator or condenser coils and faulty defrost cycles are diagnosed and corrected to restore rated airflow and efficiency.
Blower motor faults and thermostat wiring issues are tested and resolved so the system responds correctly to demand.
Stored fault codes pulled and interpreted to narrow the diagnosis.
High- and low-side readings taken before any refrigerant work.
Voltage and amp draw tests at capacitor, contactor, and motor.
Full system run-through to confirm the repair holds before sign-off.
Why Choose Us
Accountability at every step, from the first diagnostic call to the post-repair sign-off.
You receive an itemised written estimate covering parts, labor, and scope before a repair is booked or started.
When repair cost is close to replacement value, we provide a written side-by-side so you decide with full cost information.
Air-source, mini-split, and geothermal systems are all within scope, so the right local partner is arranged for your unit.
Every repair closes with a full system run-through, pressures, airflow, and valve operation checked before sign-off.
The initial visit covers overall equipment condition, not just the presenting fault, so secondary issues are caught early.
The Process
01
Tell us the symptom, no heat, icing, short cycling, or fault code, and we arrange a local partner to assess your system.
02
The technician reads error codes, checks refrigerant pressure, and runs electrical tests, then delivers a written itemised estimate.
03
Once you approve the estimate, the repair is carried out and a full startup test confirms the system is operating correctly.
