"Excellent. I can't say enough about how pleased I am with Southern Air Mechancial LLC for my Air conditioning service needs. Out of habit, I had been using another vendor who recently told me in the last 10 days that my unit was oversized for my duct work, that it was going to take 6 hours to fix it, and was about to sell me a part with installation and labor that would have cost $1400. The tech said it would break in a year and the owner basically tried to sell me a new AC unit. Got a little suspicious after asking if my unit could be adjusted since it was a variable speed down to a 3 ton and the owner said, "well, let me send my tech again". I called Southern Air and spoke to Clint, the owner. I had purchased the unit 7 years ago and without hesitation, Clint visited with his technician, and replaced the part that was a known problem with my manufacturer. He warrantied the part and was back out in two days and had the system cooling within 2 hours. I will only use Southern Air Mechanical and now know how trustworthy they are and what excellent service they provide. You can't and will not go wrong by choosing Southern Air Mechanical for your AC needs."

"I had a terrible experience with a previous contractor who charged me $2,700 and didn’t even fix my AC. Luckily, Mr. David from Air Bear came out, located the issue immediately, and explained everything thoroughly. Air Bear is a very dependable and honest company. If you want to support a fantastic Veteran-owned business that does top-notch work, look no further. I cannot recommend them enough!"

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.
