"Called EF Martin for annual furnace maintenance service. Had no problems getting someone on the phone to schedule the appointment. The attendant was very pleasant and efficient. I was scheduled for 2 - 4pm appointment. The technician arrived at 2pm, which was great. Dennis was very thorough and explained everything to me clearly. I highly recommend this company!"

"One of my AC units was not working correctly so as always I went to Angi to find someone qualified to do the work. CALL DAD HVAC called me right away and said they could come out that afternoon but due to my schedule had to wait until the next morning. Daniel arrived here promptly and worked all day until all the work was completed to my satisfaction and approval. I was so pleased with the work I decided to sign up for a year's contract with them which was very reasonably priced. If someone needs any HVAC services/repairs I highly recommend CALL DAD!"

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.
