"We were having trouble with our downstairs circuit blowing when the air conditioning was running. Adkins came and diagnosed the problem as a box too small for all the electric appliances in the downstairs. They said they could replace the broken circuit, replace the too small box, or re-organize the whole house system (it is 100 year old house) so that it all worked and could be expanded in the future. The electrical had been upgraded in pieces, and was a disorganized mess. We opted to do it right, especially since the service tech was so honest about the cost and about the different options we had. He laid out the least expensive to most comprehensive. He and his assistant scheduled the repair and they showed up when they said they would and did a great job cleaning up. They give prices out a book, so not much flexibility, but very transparent and predictable system."

"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.
