"Called Ashworth at 8:30 am Saturday morning. Air conditioner had stopped working the night before. The fellow that answered the phone was friendly, indicated they were very busy, but that they would get to my house after noon. The service tech, Brandon, called me about 3:00 pm and explained that he was running late but I was still on his schedule. When Brandon showed up he was friendly, apologetic for taking so long to show up, and knowledgeable. It took him about 5 minutes to diagnose the problem and another 30 to fix it. He had the necessary parts in his truck. Show-up fee (on a Saturday) was $89 for "diagnostics." Parts and labor for the repair was $111. VERY SATISFIED WITH THE SERVICE."

"MMG did a great job all around with my AC repair. I've had them come out twice to work on my aging AC system. Each time they were out quickly, got the job done right, cleaned up after themselves, and were professional. These guys are my go-to for anything HVAC related. I recommend them to everyone."

"Air went out on a 90 degree day. John Wilson was there that afternoon. Had to replace a fan motor. Later that night, we realized it just wasn't cooling correctly. We called john the next morning and he was here within the hour. He added gas and cleaned the coils and the best part...he didn't charge me again. Reasonable prices, fast turnaround, enjoyable service. It is now nice and cool and I couldn't be more thankful."

"Roger Prevette and his employees saved me from a real life emergency by coming to my aid during this electrical outage, never leaving me and doing everything even going above and beyond what you would normally expect from a contractor. As an owner of the company Mr. Prevette did not have to be there during my troubles, but he is a person that cares about the people that he serves and he stayed with me until final electrical inspection was completed, the power company came to reconnect my service and my whole home generator was repaired and ready for my use whenever a power failure occurs. His whole company is very professional and willing to do the best job possible. If you need any of the services that he provides, give him a call and I am sure you will be absolutely overjoyed and the service that you get. He even offered to go get his personal generator and hook it up for me if we were unable to get the other sources back into operation. To me this man is a hero."

"I had an issue with my computer where it was opening lots of pop ups, ad bars, and windows with ads for games. I had tried several different programs to try to remove it with no luck. I finally decided to call North Alabama Technical Service to see if I he could help. I was expecting to set up a time for him to look at it but he connected to my computer immediately and within an hour had it fixed and running perfect again. Great service at a great price and I didn't even have to disconnect it and carry it somewhere! Would call again if I have another issue I can't resolve myself."

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.
