"Antori and his helper were prompt and gave me straightforward information. I really appreciate how quickly and well they did the job. I wasn't happy to be facing summer with no or minimal air conditioning. I suspect this will also positively impact my electric bill. Great job!"

"Alpine provides quick service and checks out any problems. We are completely satisfied with their service and the professional quality of their employees. In January 2011 they installed a new Everrest split system 16 SEER 48,000 btu air conditioner and coil
matched with Everrest 95% two stage condensing furnace. They removed and disposed of existing unit. They put in a new condenser pad and reconnected low voltage and communicating thermostat. They removed existing duct work and installed new R-8 valve, insulated flex duct for both supply and return, sized for larger unit, and insulated existing floor boots, bringing them up to code. They installed airtight collars with dampers. In short they removed the old system and put in new heating and air conditioning units and installed new ducts throughout the house. The cost was $9084.

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.
