"We had an issue with our water conditioning system for Aquarius. They attempted to remedy the problem and determined they needed to replace the system. With the system being over 5 years old, I was uncertain what it would cost me, however, the only thing better than the equipment they provide is their customer service. No cost to replace with a better system. Now that is service!"

"They lost money on our installation. We had 2 central air units installed, and 1 of them malfunctioned. They were relentless in getting it right. Ended up putting in a whole new system. Never cost me an extra penny."

"I highly recommend Thomas with Prolific Mechanical. Another company came out and told me I needed to replace my HVAC system, but I decided to get a second opinion. Thomas took the time to properly diagnose the issue and was able to repair it instead of pushing for a replacement. He saved me a significant amount of money, was honest, knowledgeable, and professional throughout the entire process. If you?re looking for someone you can trust, Prolific Mechanical is the company to call."

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.
