"Season Control arrived on time for the estimate, gave me a lot of information about the HVAC system and which was best for my house. The installers arrived on time, put tarps on the floor, were very neat and finished the job in 1 1/2 days. It works great, quiet and very efficient. Justin was the man who came for the estimate and supervised the job. He is very professional, but not stuffy. Very nice, and knows his air conditioning systems! His price was a lot less expensive than the other three bids. I made a good choice by hiring this company and highly recommend Season Control."

"Amazing service from start to finish! The technician was very friendly and professional. He inspected the air ducts and showed me the dust buildup inside the vents. After the cleaning, the airflow in the house improved and the air feels much fresher. If you need air duct cleaning or HVAC service, I definitely recommend this company!"
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.
