AC & Heat Pump Diagnostics
We don’t guess—we measure. Expect refrigerant analysis (superheat/subcool), airflow & static pressure checks, and electrical testing under load. You’ll see the readings that support our recommendation.
When your system won’t cool—or runs forever—our technicians deliver instrument-based diagnostics, tidy repairs, and smart upgrades that actually fix the root cause. You get options, not pressure.
From no-cool emergencies to ductless design and seasonal tune-ups, we service central AC, heat pumps, and mini-splits across Pomona, Diamond Bar, La Verne, Claremont, and nearby communities.

Single or multi-zone, we handle leaks, sensors, and control boards. New installs feature tidy line-sets, deep evacuation, and documented commissioning—done right the first time.
Balance comfort and efficiency with zoning and modern controls. We eliminate wiring spaghetti and set schedules that reduce peaks and keep rooms consistent.
Coil cleaning, drain safety, capacitor checks, and airflow verification. Preventative work that protects compressors and stabilizes utility costs.
Considering an upgrade? We perform load calcs and duct evaluations to right-size your system. You get brand-agnostic options and projected efficiency savings.
Media filtration, UV, humidity control, and ventilation (ERV/HRV). We recommend what matters for your home—no gimmicks.
Most “it runs forever” issues trace to one or a mix of four things: low airflow across the coil, incorrect refrigerant charge, electrical faults, or controls at odds. Swapping parts until something sticks is expensive guesswork. Our process proves the cause first.
With data on the table, your decision is simple: fix what’s broken, stabilize performance, and only upgrade when it adds genuine comfort or savings.
Every visit ends with photos, readings, and plain-English notes. That record helps with warranty support and future service—no starting from zero.

Not a quote—just how we structure visits. You approve exact pricing before work begins.
| Service | What’s Included | Typical Window | Notes |
|---|---|---|---|
| Diagnostic Visit | Full system test: charge, airflow, electrical. Photos + report. | 60–90 minutes | Applied toward repair when approved same day. |
| Standard Repair | Common components (capacitors, contactors, sensors) + verification. | Same day | Most jobs completed on first visit from stocked vans. |
| Coil Cleaning | Evaporator or condenser cleaning, drain service, delta-T verification. | 1.5–3 hours | Often paired with maintenance for best results. |
| Heat Pump Upgrade | Load calc, duct eval, install, commissioning, documentation. | 1–2 days | Ask about current rebates and programs. |
