"Dominion Services replaced my 30-year old HVAC system (the outside compressor, and the inside air handler) with a modern one having a 50% increased efficiency rating. The quality of their work is high (four friendly employees with more than 100+ years' combined experience were involved) and have good flexibility to adjust to my work schedule. They easily adapted the new system to the existing hook-ups, and were flexible in their selection among alternate, reliable replacement HVAC systems. The replacement cost was well within the range of the national average. I recommend contacting Dominion Services for insight into any HVAC issue."

"Lahcen is an excellent HVAC technician! He quickly diagnosed the issue with my AC unit and clearly explained what was causing an error in my AC unit and while he was diagnosing the main issue, he checked my filter he found out it was upside down. Professional, knowledgeable, and honest. I highly recommend him to anyone needing HVAC service."

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.
