"Air Max came in a timely manner. Gilbert checked everything out to make sure my system was running at optimal level. Gilbert went above and beyond and was very polite. He also was very informative and explained everything so that I could understand what he was doing. Thankfully it wasn’t anything major. I will be having him back for some maintenance work. Honest person who did not try to gouge me. I highly recommend Air Max."

"It was a great and affordable service that provided us with the ability to upgrade our AC at an affordable price. Armando allowed us to not have to hire an electrician since he’s already licensed and Valeria provided us with a great quote and explained how the process works. Super thankful and recommending this company."

AC back on same day with a temporary thermostat, full replacement with new thermostat, project completed the very next day. I am very pleased and impressed that things were taken care so quickly and professionally."
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.
