Anderson Heating & Air | Experienced HVAC Services in Houston, TX

In Houston's humidity, frozen coils are often caused by restricted airflow from dirty filters or blocked vents, or low refrigerant levels. Both issues force the coil to get too cold. We'll diagnose the root cause—whether it's a simple filter change, duct cleaning, or a refrigerant leak repair—to fix it and prevent future freeze-ups.

A faulty reversing valve, a common issue with our local heat pump use, can cause your system to blow cool air in heating mode or warm air in cooling mode, get stuck in one mode, or make a noticeable hissing sound. If you notice these signs, our technicians can test the valve and perform the precise repair to restore proper function.

Regular professional maintenance is key. Our Houston-specific tune-up includes checking refrigerant levels, cleaning coils, ensuring proper airflow, and testing valve operation. This proactive service catches small issues before they lead to a coil freeze or valve failure, saving you from discomfort and costly repairs during our peak seasons.
