"Luke Mahan and his assistant Mike did the work. They ended up fixing some issues with the air conditioners which are quite old. I am very satisfied. They did a great job and explained everything they did. I would certainly hire again."

"The repairman came within a few hours of our call on a day that Baton Rouge was experiencing Hurricane Laura! The air conditioning was needed due to hot humid air outside and the family has a 6 month old baby! The problem was repaired within 45 minutes and no charge was made as we had a warrantee on the unit. I Highly recommend this company."

"I woke up one morning to a hot house ands got in touch with Air Creations staff and they were out there the same day for a last minute call! Reasonable price, not money hungry, made me feel like a friend instead of a customer, and it was the owner himself that came out and resolved the problem. I was very impressed and will certainly use them again!"

"Newton Williams was amazing and knows everything about ac, heating and electrical and more. I am so relieved. Every year someone comes to fix something. He fixed it all and cleaned the outside unit perfectly. Nobody to the time to explain or do the work he did. He let me know what it should be like and he fixed it. The air smells clean and colder than it used to get. I will never trust anyone else."

"Had signature air come out to do a maintenance on my unit only to find out it needed some repairs. After the tech finished with the maintenance he showed me pictures of what needed repairs and explained everything that needed to be done to prolong the life of my unit. He gave me a great price and we went ahead and did all the repairs. The tech was extremely thorough and professional. I’m very pleased with the work he did. I will gladly recommend signature air to all my friends and family! Amazing 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.
