"Ismael did a great job with installing new air ducts to our older house. Talked through things that weren’t up to code and fixed them. He responded to my request fast and did a free estimate the same day I sent it. It was an urgent job and he stayed within a fair price."

"Austin, Orin and James were great to work with. Due to raccoon damage to the attic insulation and ceiling drywall all old insulation needed to be removed and contaminated areas treated. They installed new soffit baffles between each pair of rafters, sealed all potential air leakage points (e.g. around can light fixtures), ran all new insulated bath fan ducts (4) to soffit mounted valved vents and blew in all new insulation. Cost was very reasonable. Overall excellent value. Austin provided my insurance company with all necessary information so the claim was quickly settled to my satisfaction. Highly recommend Greenlink Energy Solutions."

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.
