"Leahy Heating & Air Conditioning came out when my AC stopped working and the house had no air. They were able to find the issue in the system, explain what needed to be repaired, and get everything cooling again. The service was professional, honest, and fairly priced. I would definitely recommend Leahy Heating & Air Conditioning for AC repair in Gainesville and the surrounding North Central Florida area."

"Wingman H&C did a super job from start to finish. Cody came out to work up an estimate & helped me cut costs where he could. Ethan installed the ductwork & 7 vents by himself & did it all in 1 day. I could immediately breathe the fresh air. Thank you Cody & Ethan for a job well done ✔️✔️"

"My project was a complete replacement of my heat pump and air handler. Sales did not push all the bells and whistles, just what I needed and wanted. One Hour was best price out of four quotes I had gotten. The Installers had good attitudes and were pleasant to work with. They did a nice installation."

"I upgraded our home thermostat to one of those smart types. Originally I intended to do this myself with the QR Code instructions but the plug in thing in the back was a little too much for me. The process was seem-less, and the turn around time was quick. Air Serve came out quickly and got my thermostat replaced."

"I received a confirmation call soon after my appointment was made via Home Advisor. Chad came out and did a super job fixing my leaky shower valve inside the wall. He was courteous and professional. Thanks, Patricks Heating and Air Conditioning!"
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.
