"Solid work ethic. Trustworthy and knowledgeable of American-made air conditioning systems. Went above and beyond to find us the right unit - we needed the whole package replaced: thermostat, air handler and 4 ton cooling unit. Jacob worked over the weekend (in the midst of his wifeâ s birthday celebration in Orlando) making calls to find parts and sending drivers to GA and Jax so we didnâ t roast in the Florida heat. Went the extra mile to add a UV light to kill bacteria. Gave special attention to us because weâ re retired (on a fixed income); my husband is an Army veteran. Arrived when he said heâ d be here; communicated every step of the way. Earned our trust. Our 17 year-old equipment was updated with a fabulous energy-efficient system! We will recommend GreyGuard to anyone."

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.
