The JJ Air Conditioner and Heat | Expert HVAC Services in Houston, TX

In our extreme heat, the most common culprit is a refrigerant leak or a failing compressor. Both put immense strain on the system. We prioritize these emergency calls and can typically have a technician dispatched the same day to diagnose the issue and get your cool air restored quickly.

Yes, an evaporator coil freeze-up is a serious issue we see often here. It's usually caused by restricted airflow from a dirty filter or low refrigerant levels. Running the system while frozen can damage the compressor. We'll safely thaw the unit, identify the root cause—like a leak or blockage—and perform the necessary repair to prevent a costly breakdown.

Proactive maintenance is key. Before peak summer, schedule a tune-up with us. We'll clean the coils, check refrigerant levels, ensure proper airflow, and inspect electrical components. This helps your system run efficiently and reliably under heavy load, reducing the risk of a sudden failure when you depend on it most.
