"Was able to quote a reasonable price on-site and do the work that day. We ran into issues with the connection and the pro, Dana, was very diligent in figuring out where the problem was and did not leave until he was sure everything was in working order, including the drainage. Very impressive. I will use them again."

"Derek was the best handyman EVER!!!!!!!!!!!!!!!!! He repaired some roof tiles and the wood on the inside of the shed. It had leaked inside and the wood needed to be replaced. He worked until everything was done, even though it was late. He also repaired a piece of the ceiling in my dining room, that I had asked others to repair and they would not do the work. He was polite and easy to talk to as he explained some of the work he was doing. I would recommend him to anyone who needs work done of any kind. Ann Finneral"
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.
