"Will Stahl from Stahl Mechanical called me the same day that I submitted my request for a pro. He came to my home for an estimate a few days later. He was knowledgeable about AC and electric, educating my husband and I regarding the different systems available, cost and efficiency. He and his 2 guys arrived the following week on time and finished the job in less time than estimated. Will was skillful, clean, respectful and friendly. He was genuinely concerned with the quality of his work and assisted us in setting the smart thermostat and returned upon request at no extra charge to adjust the vents to balance the air flow in all the upstairs bedrooms. I would highly recommend him to others and have given his card out to friends and family already."

"Serviceman was prompt, courteous, and told me basically about what he would do to service the furnace before he started work. Reported that it was in good condition, needed only to replace the filter, which he did."
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.
