FAQ

What does an expansion valve do?

An expansion valve meters the flow of refrigerant into the evaporator coil, ensuring correct pressure drop and efficient heat exchange.

How do I know my expansion valve needs repair?

Signs include uneven cooling, frosting on the valve body, high humidity indoors, and abnormal pressure readings on HVAC gauges.

Can a clogged filter affect the expansion valve?

Yes. Restricted airflow can cause low evaporator pressure, leading to valve malfunction or icing, so clean filters are essential.

How long does valve repair take?

Most residential expansion valve repairs complete within 2–4 hours, including diagnostics, valve swap, and refrigerant service.

Will repairing the valve improve my energy bills?

Absolutely. Restoring proper refrigerant flow reduces compressor workload and run time, lowering electric consumption.

Is refrigerant recharge included in the repair?

Yes. After installing a new valve, we evacuate air and recharge the system to the exact manufacturer-recommended charge.

Can I delay expansion valve repair?

Delaying can lead to compressor strain, increased energy bills, and eventual system failure. Prompt repair prevents more costly breakdowns.

Do you warranty your expansion valve repairs?

Yes. All repairs come with a 1-year parts and labor warranty to ensure your system functions reliably.
