GLS Heating & Air Conditioning | HVAC Services in Pomona, CA 91766

Short cycling is a common issue in our area, often caused by an oversized unit, a dirty air filter, or refrigerant problems. It strains your system and increases energy bills. At GLS, our specialists first perform a thorough diagnostic to pinpoint the exact cause—whether it's related to installation, a simple maintenance fix, or a needed repair. We then provide a clear, efficient solution to restore proper operation and comfort to your Pomona home.

A proper installation is critical for efficiency and longevity. Our process starts with a detailed assessment of your Pomona home's layout, insulation, and your family's comfort needs. We don't believe in a one-size-fits-all approach. Our qualified personnel will recommend a correctly sized and compatible system, then execute a precise installation, ensuring everything from ductwork to thermostat integration is handled with care. CEO Jeff C. stands behind every job, promising personal attention if you're not fully satisfied.

Regular maintenance is key to preventing unexpected breakdowns, especially during our hot summers and cooler nights. Our maintenance service includes cleaning, inspection, and calibration of your system's core components. This proactive care improves efficiency, lowers utility costs, extends your system's life, and can catch small issues—like thermostat connectivity problems—before they become major repairs. As a local, family-run business, we aim to keep your system running reliably year-round.
