"They are excellent across the board. We came home from vacation to find we had no AC in our upstairs. Mike got here the next day and got it fixed. Anybody he has ever sent to our home, has been just as professional and reliable as Mike himself. I can't say enough good things about Cool Comfort."

"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."

"The A/C repair technician (Jonathan) was very thorough in his troubleshooting. He is extremely knowledgeable and clearly explained the diagnosis and repair options. He explained the immediate repair as well as issues to anticipate with my fairly old (15 year old system), including the caution that my systems R22 refrigerant is no longer being produced and is becoming cost prohibitive to replace (I.e. for recharging). T.Byrdâ s gave an excellent price for the parts replacement and repair. Jonathan also explained the efficiencies of current models and a ballpark figure and timeframe that I could use in planning for a full unit replacement. Outstanding work, outstanding on-site customer service. And special thanks to HomeAdvisor & Angie for including T.Byrdâ s Heating and Air, LLC among the referrals for obtaining estimates and service date availability. This has been a great experience and it was a big deal for our A/C to fail just as the Charlotte summer heat had gone Inyo the 90â s!"

"Installation of window ac/heating unit; removal of old unit."

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.
