"From beginning to end, The Right Choice Heating and Air Conditioning Co. provided superior quality customer service and onsite work. From scheduling, to multiple follow-ups and reminders, re-confirming exact appointment time, and the post-inspection follow-up, they have truly impressed us. More importantly, Michael Taib, the technician who performed the work at our home, was indeed a true gentleman and professional. He was extremely knowledgeable and patient. I am familiar with the type of HVAC related work requirements, the lingo, and technician data. I quizzed him several times and he constantly responded with 100% honest and factual answers. He tirelessly worked on both of our HVAC units and performed the necessary services and repair. He was polite, courteous and clean. His most impressive talent was ensuring my wife's absolute confidence in his work after she grilled him with so many questions! We will continue to refer True Choice to all our friend and family! Call them; you will not be disappointed."

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.
