What's Actually Wrong With Your AC

When a Richardson AC system stops cooling properly, the underlying cause is almost always one of a small set of failure modes. Knowing which one matters because the right repair is sometimes a $250 capacitor and sometimes a conversation about whether the system is worth keeping.

Capacitor failure. The single most common AC repair in Richardson during peak summer. Run capacitors fail in the heat — typically in July and August when the system has been running for weeks at full capacity in 100-plus degree weather. Symptoms: the outdoor condenser hums but the fan doesn't spin, or the system tries to start but trips the breaker. Repair time is usually under an hour. Cost is in the $200 to $400 range for the part and labor.

Refrigerant leak. A more expensive diagnostic but a critical one. Older R-22 systems (any system installed before 2015) often develop refrigerant leaks at coil joints, line set fittings, or evaporator coils. Symptoms: cooling capacity drops off gradually, ice forms on the indoor coil, the outdoor unit runs continuously without bringing the home down to setpoint. R-22 refrigerant is no longer manufactured and has become very expensive — for older systems, the leak repair conversation usually leads to a system replacement conversation. Newer R-410A and R-454B systems can typically be leak-repaired economically.

Compressor failure. The most expensive failure mode. The compressor is the heart of the system, and replacement on a 12-plus-year-old system is often more expensive than a system replacement and rarely makes economic sense. We diagnose compressor failures honestly — if the system is older than 12 years and the compressor has failed, we'll quote both compressor replacement and full system replacement and let you make the decision.

Contactor and electrical failures. The contactor is the relay that engages the compressor and condenser fan. Pitted, burned, or failed contactors are a common Richardson summer repair, often associated with brownouts or voltage spikes from the grid. Repair is typically under an hour and under $300.

Frozen evaporator coil. Caused by airflow restriction (dirty filter, blocked return), low refrigerant charge, or a failed blower motor. Symptoms: warm air from the vents while the system is running, ice visible on the indoor coil or refrigerant lines. The repair starts with diagnosis to identify the root cause — replacing the filter doesn't solve the problem if there's a refrigerant leak driving the freeze.

How Our Diagnostic Process Works

When you call us for AC repair in Richardson, we don't quote a price over the phone. The reason is simple: a $200 capacitor and a $5,000 compressor present with similar symptoms, and giving you a number before we've actually looked at the system is dishonest.

The diagnostic process on site:

1. Symptom verification — confirm what you're experiencing matches what we're seeing
2. System inspection — outdoor condenser, indoor air handler, refrigerant pressures, electrical components, airflow
3. Failure mode identification — what's actually wrong, not just what symptom is most visible
4. Repair quote — price for the specific repair, with parts and labor itemized
5. Repair vs. replacement context — if the system is older than 12 years or if the repair cost exceeds 30 percent of replacement cost, we'll have an honest conversation about whether the repair makes long-term sense

The diagnostic fee is applied toward the repair if you proceed. If you decide not to repair, the diagnostic fee covers our time on site.

When AC Repair Stops Making Sense

There's a point at which continuing to repair an aging system stops being economically rational. The general framework we use in Richardson:

Under 8 years old: Almost always repair. The system has remaining useful life and the repair pays back over the years left.

8 to 12 years old: Depends on the failure mode and the cost. Capacitor and contactor failures are easy yes-repairs. Compressor or major coil failures start the replacement conversation.

Over 12 years old: Most major repairs (compressor, evaporator coil, condenser coil) are not worth doing. The remaining system has low remaining useful life, the rest of the components are aging in parallel, and a new inverter heat pump system will pay back the difference in 5 to 7 years through reduced energy consumption.

R-22 systems (typically pre-2015): Refrigerant cost alone often makes repair uneconomical. R-22 has not been manufactured since 2020 and current refrigerant pricing reflects scarcity.

We won't push you toward a replacement that doesn't make sense, and we won't repair a system that's a poor investment without telling you so.

What Truficient Does Differently

Most Richardson AC repair calls we get start with someone who's been told by another company that they need a $7,000 replacement when they actually need a $300 repair. We take a different approach: identify the actual failure, quote the actual repair, and have an honest conversation about long-term economics.

Eric, Truficient's owner, is an engineer. Every diagnostic decision is technical, not commission-driven. If your system has 5 good years left and a failed capacitor, we'll replace the capacitor and let you keep running the system until it makes sense to replace.
