"Mark Vargas and Proctor from Will's All Pro - Plumbing& Air Conditioning were OUTSTANDING! They called 30 minutes prior to the appointment. They came to the appointment for a bid on time. They presented the bid and gave us concise information on what would be taking place and how it would be resolved and how long it would take. We were please with the amount and hired them for the project. They completed the work in a very timely manner and cleaned up whatever mess from the project. They were professional at all times. But were pleasant and courteous. I will recommend them to any of my neighbors, friends and family; and on my facebook and twitter accounts. Thank you HomeAdvisor for sending the very best! With best regards, Sharon M. Stellburg"

"They were very great on their installation. They did everything they said they were going to do. It turned out amazing. They upped the size of the unit based on the age and insulation of my house and now I can actually feel air coming out of my vents. I would definitely recommend them to friends and family. A great price too!!! They explained everything that they would do before hand, and followed through on all of it. Thanks guys!"

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.
Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.
Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.
Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.
Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
