"Said fixed the leaking pump but noted that there were some hazardous conditions caused by the way the unit was originally installed. Suggested that I call PG&E for a safety inspection. Did so and they confirmed that there were indeed small gas leaks due to faulty and ancient installations. PG&E did repairs and I am getting proposal for repair of the 90 year old gas lines. Really appreciate Said's thoroughness and honesty. Could not recommend anyone more highly!

"I needed to have techs come back to fix 2 issues after the install, one was a loose wire connection going to the fan asm. and the other was a rain / water leak from the roof hood covering the air input / exit. In both cases, the techs found and fix the issues in a timely manner and their troubleshooting was spot on¦. The install did take time but it was impressive to watch them remove a 40 years old unit and install a new one.¦"

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.
