HVAC Services in Pomona, CA

AC repair costs vary depending on the issue — a simple capacitor swap is very different from a compressor replacement or full system changeout. We diagnose the problem first, then give you a clear, upfront quote before any work begins. Call 909-764-3214 to schedule a diagnostic visit and get a personalized estimate.

We recommend professional HVAC maintenance twice per year: once in spring (before AC season) and once in fall (before heating season). During a tune-up, we clean coils, check refrigerant levels, inspect electrical connections, test safety controls, and replace filters. Regular maintenance prevents breakdowns and can extend system life by 5+ years.

Common causes include low refrigerant from a leak, a dirty or frozen evaporator coil, a failed compressor or capacitor, clogged air filters restricting airflow, or thermostat issues. In the Inland Empire heat, an undersized or aging system may also struggle to keep up when temperatures exceed 100°F. A professional diagnosis is the fastest way to identify and fix the issue.

HVAC sizing depends on square footage, insulation, window exposure, ceiling height, and local climate. A general rule for the Inland Empire is 1 ton of cooling per 400–500 square feet, but a proper Manual J load calculation ensures the right fit. An oversized system short-cycles and wastes energy; an undersized one can't keep up in summer.
