Progressive Heating & Air - El Cajon's Trusted HVAC Repair

Short cycling, where your system turns on and off too frequently, is often caused by an oversized unit, a dirty air filter, or refrigerant issues. It's a common problem here that strains your system and increases bills. Our technicians will perform a thorough diagnostic to pinpoint the exact cause, whether it's a simple cleaning, a refrigerant recharge, or advising on system recalibration, to restore normal operation and efficiency.

Our coastal-influenced climate can accelerate corrosion on your condenser coil. We combat this with proactive maintenance, including gentle coil cleaning to remove corrosive salt and mineral buildup, inspecting for and sealing minor electrical connection corrosion, and applying protective coatings when recommended. Our seasonal tune-ups are designed to catch early signs of wear and protect your investment from our local environmental factors.

We strongly recommend bi-annual maintenance—once in spring for your cooling system and once in fall for heating. This service includes checking refrigerant levels, cleaning coils and components, inspecting electrical connections, and calibrating your thermostat. This proactive approach is the best way to prevent the short cycling and corrosion issues we see frequently, ensuring your system runs reliably and efficiently through every season.
