"New Life Handyman Services owned by Bobby Nesbitt is a very reliable, professional and friendly business. We had a few drywall repairs that were rather tricky and he made the work look easy. He restored each repair location to its original paint and visual condition. I would highly recommend Bobby Nesbitt for any drywall, carpentry or remodeling projects."

Ready Air HVAC provides professional heating, cooling, and indoor comfort services for residential and commercial customers throughout Maryland. We specialize in HVAC repairs, new system installations, replacements, preventative maintenance, and tune-ups for air conditioners, furnaces, heat pumps, boilers, and ductless mini-split systems. Our technicians diagnose and repair HVAC problems of all sizes and can help customers choose the right equipment when it’s time for a replacement. We also provide commercial HVAC and refrigeration services, including maintenance and repairs. Whether you need routine service, an emergency repair, or a complete new HVAC system, Ready Air HVAC is committed to providing dependable service, quality workmanship, and straightforward solutions.
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.
