"Brandon came out on a Sunday and looked over the job site for details needed to present an estimate. Within a day I had the estimate with 3 options from low to high, all of which were reasonable the only difference being what equipment I wanted to install. Option #1 and #2 were lower end brands that were less expensive but since the difference in price betwee Option #1 and Option #3 was about $1400, I went to Option #3 which was their top tier brand, Carrier that clearly is an industry leader and trusted brand for longevity. I was installing a SINGLE ductless to cool a standard bedroom size room with a 18,000 BTU unit. The job took a total of about 5 hours since they were mounting the unit in a second floor bedroom and they needed to run the power/refrigerant lines two stories down to the compressor mounted on the wall. Everyone from Office Staff Jim to installers were absolutely wonderful to deal with. You can trust this company."

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.
