"I received a phone call from the Boy's AirTech office the day before my scheduled service call confirming my appointment for the following day. The day of the appointment, I received a phone call from Chuck (service tech) to let me know that he was en route to my home and his estimated time of arrival. Upon arrival, Chuck immediately started a thorough system condition and performance inspection, using a detailed checklist. During this process, Chuck asked several questions about the system's history and past maintenance. He also offered several suggestions about ways to improve the system's function and upgrade its performance and efficiency. At the conclusion of his inspection, he sat down with me and gave me a summary report of what he found and provided me with a copy of the checklist - as well as a quote for the items that he recommended earlier that could enhance the system's performance. In summary, I was impressed with Chuck's thorough, professional, and courteous manner. This is what I've come to expect from Boy's AirTech. I've used their heating and air conditioning services four times and I've been quite pleased with the company and its people every time. I highly recommend them."

"They set up an appointment with us the same day we called and even offered to call on their way to our house because my husband and I were both busy that day and that allowed us to be home when they got there, but not have to sit around all day waiting. They quickly repaired our air conditioner and had us up and running again. Great job!"

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.
