HVAC Repair Houston TX | Call Century A/C Supply

Yes, that's a classic sign of a failing reversing valve, a frequent issue here. The valve switches your system between heating and cooling. When it gets stuck, often due to wear or debris in the lines, it can't properly reverse the refrigerant flow. We can help you identify the correct replacement valve for your specific unit to get your heat restored.

Freezing coils are often caused by restricted airflow or low refrigerant—common problems in our area due to dirty filters, blocked return vents, or slow leaks. A frozen coil can't absorb heat, shutting down your cooling. We carry the coils, filter dryers, and refrigerant accessories needed for a proper repair to prevent recurring freeze-ups and protect your compressor.

For reversing valve issues, check the valve solenoid coil and the valve body itself. For freeze-ups, start with the air filter, thermostat fan setting, and the metering device (like the TXV). We stock these critical components and can guide you through troubleshooting. Having the right part on hand means a faster, more affordable repair, getting your comfort back online quickly.
