"This company was just wonderful. Our new home had a huge job and they got it all completed in one day. They worked a 12 hour day just to insure we had air conditioning when we went to bed. Heath was amazing and very knowledgeable."

"Josh came early to the appointment, introduced himself and immediately placed shoe covers over his shoes upon entering my home. He was beyond professional and explained everything that he found and the plan to repair the heating issue prior to getting started. He also made recommendations for maintenance but wasn't pushy in trying to make me buy anything extra. I HIGHLY recommend this company and will not only utilize T.Byrd's Heating and Air again, but I will refer them to my friends! Keep up the good work guys!"

"Zach arrived on time and completed 98% of the task I had outlined. He will be returning next week to finish hanging the bar light fixture and another kitchen fixture. I had ordered extra parts to complete this and he will finish up as soon as I receive the parts. Zach went above and beyond performing these tasks for me. He left all work areas in immaculate condition. My only regret is that he can not help finish everything I need to get my house ready for sale."

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.
