"Ray's HVAC responded quickly to my request to repair my furnace, which could not start this year. They were able to find and fix the real cause of the issue - a bird net in the PVC pipe which blocked the air flow, and made my furnace is working again!"

"This was the first time I hired a company to professionally clean my air ducts and dryer vents. Green Ductors worked well with all of my needs. They were professional and courteous. Igor took the time to explain the process from start to finish, what work was included for the price, and cleared up all of my questions. Igor called 24 hours before the start of the job to confirm. The technicians arrived 10 minutes before their scheduled time and explained the process once more! Ivan cleared up additional questions I had and completed a thorough check of my HVAC system, ducts, and vent. He took photos and explained their assessment of my system. They took their time and were mindful. They carefully moved furniture if they needed to and placed it back in its original position. Once the job was complete Ivan took photos and explained the work they completed. He sent me both sets of photos and shared some maintenance tips. I highly recommend Green Ductors!"

"This company was referred by Home Advisor and they were the first local contractor to call back. They were at the property early in the morning, avoiding impacting customers. Their quote on a central air conditioner was in line with other quotes. There work was prompt and professional. They used a Fujitsu split air system of an appropriate size. They had the best guarantee of any of the local companies. Customer service was the best, I always dealt with a single representative, even on weekends and evenings. I would 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.
