"Having had bad experiences in the past, I can be pretty wary of contractors, but I need not have worried with Riley! We were in a no-heat situation during cold weather and he was able to move things around and get to us within a few hours. During the diagnostic, he insisted I was present as he walked me through what he was testing and what the expected results would be. There was full transparency. Once the issue was diagnosed, Riley offered different options to solve the issue. There was no sales pressure, he wanted to find the right option for us. Given the age and condition of our system we opted for a new HVAC system and Riley presented us with different solutions, again with no pressure. The installation was scheduled quickly and I was amazed with the quality of the workmanship and service he offered. His pricing is very fair but in terms of value for money, his service, professionalism, and workmanship easily beats any of the ‘big names’."

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.
