"Called Ashworth at 8:30 am Saturday morning. Air conditioner had stopped working the night before. The fellow that answered the phone was friendly, indicated they were very busy, but that they would get to my house after noon. The service tech, Brandon, called me about 3:00 pm and explained that he was running late but I was still on his schedule. When Brandon showed up he was friendly, apologetic for taking so long to show up, and knowledgeable. It took him about 5 minutes to diagnose the problem and another 30 to fix it. He had the necessary parts in his truck. Show-up fee (on a Saturday) was $89 for "diagnostics." Parts and labor for the repair was $111. VERY SATISFIED WITH THE SERVICE."

"I had another air conditioning project that would have been quite costly, but advice from Chris led me in another direction, which saved me at least $1000,00. He could have easily taken advantage of my situation, but did not. For that, I thank him."

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.
