A frozen evaporator coil is often caused by restricted airflow, typically from a dirty air filter, or by low refrigerant levels. Both are common issues in our climate. We recommend checking and replacing your filter monthly during peak seasons. If the problem persists, our technicians can perform a precise diagnostic to identify and fix the root cause, such as a refrigerant leak or a faulty blower motor, to prevent recurring freeze-ups and protect your system.

For most homes in Independence, we recommend checking your standard 1-inch filter every month and replacing it at least every 90 days. During heavy use in summer and winter, or if you have pets or allergies, monthly replacement is best. A clogged filter is a primary culprit for reduced efficiency, frozen coils, and even system failure. It's a simple, cost-effective step to maintain your comfort and avoid unexpected repair calls.

Watch for warning signs like uneven cooling/heating, strange noises (hissing, grinding), a sudden spike in energy bills, or constant cycling on and off. These can indicate deeper issues like refrigerant leaks, ductwork problems, or component failures common with our local temperature extremes. Our expert technicians can perform a comprehensive inspection to diagnose these problems early, saving you money and preventing a complete breakdown during a heatwave or cold snap.
