"Brad was the first inspector and let us know right away that we did not need our ducts cleaned, but that we had a water leak, and our vapor barrier was torn and that our duct work around the leak was pulled away from the air supply. They were great to get back to our home and complete the job after we had the leak fixed. They were great to work with and safety and good work were at the top of their priority list. Would hire them again!"

"The owner of Apex Residential Services and the men working for him were on time and professional. I was given the choice of appointment times that fit my availability. Apex kept the set schedule. Very proficient and knowledgeable in their work. Communication is phenomenal as they explained everything from what they were doing to why and what they were looking for. The owner worked with his guys instead of standing around or giving orders. Would highly recommend Apex Residential Services for maintenance, service and repair of your system. Would highly recommend for replacement also. Apex tells you the truth and facts and then gives you options."
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.
