"Fantastic experience with Aviator Heating & Cooling. They repaired our Daikin heat pump instead of trying to sell us a new one. Fast response, knowledgeable technician, and fair pricing."

"They were just extremely professional and very very good. I did have a problem during the year with an adjustment for summer and winter for upstairs. They came out and they had already put a bracket in to adjust for summer and winter that I didn't know about and didn't understand. They went beyond what they needed to do. They came out and showed me. It took 10 minutes and I was able to change my heating and air upstairs. I would recommend them to anybody."

"Devin came on time, quickly diagnosed the problem, had the necessary replacement parts, repaired our central air conditioner, and had us back up and running within an hour. Great job. Would hire again."
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.
