Family Air & Heat - Metairie's Local HVAC Repair

In our high humidity, this is often caused by a frozen evaporator coil or a refrigerant leak. The coil freezes when airflow is restricted (from a dirty filter) or refrigerant levels are low, preventing it from absorbing heat. Our technicians will check these key components, clear any blockages, and ensure your system is properly charged to handle Metairie's sticky summers.

First, check your circuit breaker and replace the thermostat batteries if applicable. If the issue persists, it could be faulty wiring, a blown fuse in the air handler, or the thermostat itself failing due to age or power surges. We can diagnose the root cause, whether it's a simple fix or a recommendation for a more reliable, programmable thermostat better suited for our climate.

The most critical step is changing your air filter every 1-3 months to maintain proper airflow and prevent coils from freezing. We also recommend an annual professional tune-up before summer. This includes cleaning the condenser coils, checking refrigerant levels, calibrating your thermostat, and inspecting electrical connections—all vital to ensuring your system can withstand our extreme heat and humidity.
