D&E Heating and Air - Rockwall's Local HVAC Services

This is a common issue we see in Rockwall homes, often caused by an overheated compressor. It can be due to dirty condenser coils restricting airflow, a failing fan motor, or low refrigerant levels. Continuing to run it can cause further damage. It's best to turn the system off and call us for a diagnostic. Our technicians will quickly identify the root cause—whether it's a simple cleaning, a motor replacement, or a refrigerant leak repair—to restore your cooling efficiently and prevent a complete breakdown.

Yes, a refrigerant leak is a very likely culprit, especially in older systems. Refrigerant is essential for absorbing heat from your home; when it's low, your AC loses its cooling capacity and works overtime, driving up energy bills. Our technicians use specialized electronic leak detectors to pinpoint even the smallest leaks. We then repair the leak, evacuate the system, and recharge it with the precise amount of refrigerant specified by the manufacturer, ensuring your unit cools effectively and operates at peak efficiency again.

Proactive maintenance is the key to prevention. Our seasonal tune-up services are designed specifically for our local climate. We thoroughly clean the critical components (like condenser coils), check refrigerant levels and pressure, inspect electrical connections, lubricate moving parts, and ensure the entire system is operating safely and efficiently. This regular care can catch small issues before they become major repairs, extend the life of your equipment, and help you avoid the discomfort and expense of a breakdown during the peak of summer.
