"May 12, 2025 - This was our first time working with Greenwell since leaving a local competitor and Chad Russell was our technician. Our basement flooded and our sump pump needed replaced. Start to finish, Chad completed the job in less than three hours. I will be requesting Chad for all future work with Greenwell."

"Just did a absolutely fantastic job. Had hail damage to our screened porch and a few window screens. Recommended a more durable type screen for the porch. Went with that and we are so happy with it. Our house is on a fall away lot, so porch is a story off the ground. Have bushes on one side as well. Was amazed at how he tackled it all and got the job done. One panel came loose and got bent on one of the very stormy night, some weeks later. He came back out and replaced it all. Was a complete pleasure to talk to and won't hesitate to call him again. Have recommended to my neighbors as well."

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.
