"Highly recommend! The air conditioner on my second floor was out. They were able to come check it out immediately. Rhett diagnosed the problem and had everything that he needed to repair it that day. I was even more thankful when I received the bill!"

"I hired GSM Services to replace my A/C unit and furnace with a newer, upgraded system. A few weeks ago Kelly came to my house to give me an estimate for a new heating and air system. He was on time and very professional. He surveyed my existing system, took measurements of my house, and did some calculations to determine exactly what type and capacity system that I would need. He showed and explained to me several options as well as their prices. He wasn’t pushy as he left in order to give me time to review the different options before making my decision. I called the office the next day with my decision and to set up a date and time for installation. Today (May 22) Kyle and Craig showed up on time and were extremely professional as well. They worked from 8:30 to 5:30 completing the replacement of my entire heating/air system. The field team leader also showed up just to ensure that everything was going smoothly. They were very helpful in answering any questions that I had throughput the day and they took the time to explain to me about the new system after installation was complete (I.e. how to operate the new programmable thermostat). Overall, it was a great experience and I will definitely use them again."

"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 company! My family and I had Travis come out and fix us up a couple of years ago and we knew we would need a new system eventually so we were prepared when that day came. Not only did Prair do the install in a timely matter, they noticed our duct work was sub par w some mold issues. We got new duct work and a remi halo air purifier system and letâ s just say we are breathing better and the sniffles and allergies have gone away! Thank you Travis!"

"Very quick to respond as well as to come out and look at the problem. Turns out it wasn’t what I thought it was. Had to replace outside unit. Got it done in timely manner. Highly Recommended!!"
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.
