We are very happy that we were able to hire Warlock Air Conditioning for our home. So happy to have a thermostat that is easy to set. Overall, great job, good American Standard product, and honest, efficient people."

"Troy and Sinclair Air ended up working on my HVAC because the contractor had hired an unlicensed person who could not get the system to operate. It was the perfect situation where his interest could have easily been minimal. Instead, he took great care and lots of time addressing the issues, suggesting changing the registers, and all around exhibiting great professionalism. I would recommend Troy in a heartbeat and wish all vendors were as personable and professional."

"Our AC stopped working suddenly due to a grounded compressor. He came out to our house that night, helped diagnose what went wrong (while showing me all the steps he was taking) and was back the next day with a new unit to install. Friendly, punctual, and always kept me updated on everything. Will definitely recommend to family and friends!"

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.
