"I called the Cape Fear Air Conditioning & Heating's Fayetteville location last Thursday and the person who answered the phone and scheduled the appointment was nice, and thankfully was able to get a technician scheduled to come out the next afternoon. The technician, Jeff, arrived on time, was professional, and was very nice. The technician was A+ and I would highly recommend Cape Fear A/C & Heating. I would definitely call them for future services needed and I appreciate the great customer service. Thank you! :)"

"While Landen Air was quick to respond I wasnt told I would be charged $94 for the service call. I believe that I was getting a free estimate. The other thing that bothers me is that I was told and was it stated on my receipt that the work would not be guaranteed. Finally, I did request an estimate to replace my system. I have not heard from Landen Air regarding the ;free estimate."

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.
