"When our unit got confused and started blowing hot air while in cool mode last night, we reached out to Aireserv. Jason T came out on a rainy Sunday evening to help get our unitâ s issue diagnosed. He was dedicated in finding the issue to get our air back on quickly in this humid Alabama weather. Jason had a positive attitude and kept us informed of all costs and repairs needed to get the unit to last for years to come."

"Alan and Daniel replaced my ductwork this summer. Excellent quality of service and super friendly people. Very responsive and takes care of their customers. On 12/23 our heat started blowing cold air. I couldn't get an appointment with anyone and it was 52 degrees in our house with a newborn baby. Thankfully I still had Daniels number and he was kind enough to get someone out within the next two hours. Alan diagnosed the issue quickly and worked hard in the sub-20 degree weather for several hours until it was fixed. Around 10 o'clock that night, Daniel texted me to make sure we had heat before he went to bed. Fantastic company and truly incredible customer service. Won't use anyone else."

"John and Zack from Bama Air Systems were personable and professional as they replaced our old mini split system with a quality mini split. The four other companies that came out before Bama didn't have a clue on what to do. Thanks Bama Air!"

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.
