"We had a repair completed in August by another air conditioning company. They recommended a repair that would have cost an additional $3,100. After 3 phone calls to the other company and no response, we received a flyer in the mail for Southern Comfort One Hour. We contacted Southern Comfort One Hour and agreed to a maintenance contract. The technician recommended we consider a new air conditioner. We agreed and the meeting with their sales professional was great. He offered a system with a great warranty, efficiency rating, and air cleaning system (Both my wife and I have allergies). In addition, the price of the system was a great value and they installed it the next day! The installers noted some inefficiencies in the duct-work of the old system and corrected them to improve the airflow of the new installation. Great work and very professional staff."

"I needed a new A/C unit, both inside and out at my apartment in Ocala. Dave and Christian were ..... so great! Polite, kind, professional, courteous. They both introduced themselves, asked if they could the sink or bathroom. Just super nice guys. They collaborated well together and helped each other out. They said please and thank you and I got you to each other! (I work in HR--- can you tell?) My expectations were exceeded with these two. I will recommend your company to anyone I know. Well done!!"

I'm the business owner & operator I have been doing this for a year
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.
