"Tony did a great job replacing my broken 50 gallon self venting hot water heater. It is in a difficult space to maneuver getting the old one out and the new one in. He did a great job updating what needed to be done (in my old 1910 home so there is always something!) and I feel very confident in their work. Limelight is my go to place and am so glad I found them!"

"I signed up 3 years ago to the Swan Club, which includes yearly inspections of our furnace, ac, and plumbing. Mark recently inspected our air conditioning system. After purchasing an HVAC system from Swan, we joined the Swan Club, which includes yearly inspections. Yesterday our service technician was Mark. He was extremely thorough and professional, and and walked us through the whole system with pictures and comments. He could not have been more helpful. Thanks Mark"

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.
