"Chad was great to work with. He came out and explained my options with respect to just changing out my heat pump versus replacing both the outside unit and replacing the backup gas furnace. Joe and Jake came out and professionally installed my new units along with putting in a new hot water heater. They worked on the install until late evening and did a very good job. They cleaned up after themselves and left the job site in pristine condition. I will definitely use Virginia Carolina Heating and Cooling for any air or heating problems in the future. They were very honest and hardworking people that I highly recommend."

"Mr. Tilley is to great work with and very knowledgeable. He came out the same day I called and validated my findings. Late the night before it was scheduled to install the unit I called to go ahead and replace my second aging unit as well. To my surprise, his crew showed up and installed both units the next day. I wouldn't hesitate to recommend Mr. Tilley to anyone that has HVAC needs."

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.
