"Our heating system stopped working late in the evening, and Tech Joy from AMJ Air responded very quickly. He was professional, friendly, and able to diagnose and fix the issue the same night. It’s rare to find a company that responds that fast and actually resolves the problem. I’m very satisfied with the service and would highly recommend AMJ Air. — Lucas Morris"

"We had excellent service from Old Dominion Heating and Air Conditioning. He called us within in minutes of receiving our request for service. He was out the very next day. Found the problem went over every detail with us. We had 3 other technicians come out from different companies and none of them could find the problem but they didn't even take the cover off to look at the inside of the Mini Split. Old Dominion gave us a fair price to fix the unit and they ordered the parts and had the work done the day after parts arrived. We can say we are more than pleased with their service and would highly recommend them. They went above and beyond to find the problem. Great Job and very polite."

Certified hvac technician who is fast and reliable.
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.
