"I chose them because they had the best quote, but were still professional. They arrived on time, were very professional, cleaning up well after each day's work. Turns out the air didn't work. We discovered this on a Sunday. They came over within a few hours and fixed the problem immediately. No issues since."

"Excellent. Max arrived on time and got straight to work. He inspected the furnace, took measurements of the air temp and cleaned all the filters. He provided some helpful information for the potential future replacement of the furnace with options and estimates. Max was professional and personable. The total cost was as quoted. Other companies I contacted either would not give me a quote over the phone, charged to just dispatch a technician, or quoted more than double."

"Great team. While the job is messy as they have to work under your house. Aire Serv was great to work with. We needed new ducts and boots and my house is now moving air better than it has in twenty years. Highly recommend Aire Serv."

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.
