"I was contacted immediately. They came the next day and it took 3 trips to figure out what was wrong, but he figured it out and I was not charged for the additional trips. I have a 20-year-old furnace and it was being stubborn. Very friendly people. Reasonable prices also."

"Mr. Workman installed a bathroom fan/light/heater in my home. I cannot say enough good things about this gentleman. He works nonstop, is knowledgeable on so many levels, and his workmanship is very impressive. He is neat and a complete professional. Cecil has painted several bedrooms and installed ceiling fans for me. He also put a heat resistant film on my storm door which required an exceptional amount of patience. A better worker you will not find!"

"The Liberty Air crew showed on time and began removing the old system and fabricating new duct work to fit the new system. They worked non stop for about 6.5 hours and had finished the preliminary installation of the new system. The following morning they returned and completed the outside work installing the new compressor unit and related plumbing/wiring. I was amazed by the size of the new unit, it was clearly larger than the one previously sitting on the pad. John had explained during the estimate, the the builder had installed a unit too small for the size of the home, which caused some of the problems. Liberty Air did a great job and I complemented them on their attention to details. Everything fits, the wiring is tucked away nicely and the system runs perfectly. And - I have a heated garage!"

"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.
