"Chad came out the same day and did a very thorough analysis of the inside and exterior heat/AC unit. He changed the filters and all his recommendations to both me and with my husband on the phone as well about his concerns. We value his expertise and we are very impressed with this company. Glad we made the decision to switch to ARS."

"Upstairs would not cool down with the unit on, called indoor mechanical and Robert and Josh came out within 24 hours. Did a lot of testing and looked everything over and turned out needed and entire new unit. Had a price same day and an appointment set. They were on time, professional, cleaned and made sure everything was running right and even checked to make sure the kids rooms had good air flow to keep them comfortable during these warm spring days in NC. Could not ask for a better outcome to a crappy situation that is going to happen eventually when you own a home. Indoor mechanical will be my go to for anything they offer."

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.
