"Brian initially came out to repair my existing broken AC unit. He went over what was wrong, and that being over 20 years old, the AC unit was going to be more expensive to maintain and may not run for very much longer. Brian was upfront with all of the costs for a new unit, which we decided to go with, and gave a very reasonable price for the service. Brian and Angel came out and got the job done quicker than expected. They will be my go-to for heating and air from here on out. Highly recommend!"

"Glenn Julian, the owners son, arrived within the expected time window. He allowed me to watch as he explained the various tests of the air conditioning that he was doing and he also described some of the previous experiences he has had with air conditioning systems. He seemed very knowledgeable and experienced. He finished the air conditioning maintenance check within one hour. We plan to call Julian's Heat & AC again in the fall when we need to have the heating system maintenance check done. Thank you Julian's Heat and AC for a great job done!"

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.
