"This was my spring check up on air conditioner before running.. Everything went very well. Everyone should have a service contract with GSM they are the best. I have tried others but they do not compare to GSM."

"Service Tech msg when he was on his way. Arrived on time and was very professional. However, the estimate for the replacement unit was 3 times higher than what a unit should cost to replace. So needless to say, I was disappointed in their quote."

"Our a/c broke and I put a request for quotes on Angies List. Tara from Ace called me within 5 minutes. She sent out Daniel and he was so thorough. Another company came and said it was a leak. Daniel didn’t find any leaks and he thoroughly looked. He had the air up and running in 3 hours. I highly recommend this company."

"Great experience! Highly recommend his services!"
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.
