"Prompt, on time for appointment. My cooling cooling quit overnight with temps in the mid to upper 90s I was overjoyed with his quick response. He Made a through evaluation and repair of my heat pump. He also did service check on my air conditioning and a second heat pump. He gave a complete explanation what services he performed and discussed trouble spots that will need to be addressed in the next scheduled service."

"I felt taken care of! I reached out the night before indicating that our furnace was not working. I received a text message and a voice mail from the owner of the when I woke up. He seemed to care that we got our heat back asap. I reached out to him and he sent his tech Josh out to help us. Josh found the issue, found the necessary part, after at least one lead, got it installed and my family is warm again. I would definitely recommend T. Byrd Heating and Air to snyone that asked!"

"Great service at a fair price"
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.
