"We just had a full HVAC system installed by Ace & A, and couldn't be happier. Every step of the process was excellent from the initial repair call and scheduling, working with sales on a new system consult and the system installation experience. Because we were without air conditioning, they worked hard to get us in and scheduled a Saturday. We appreciated the professionalism, courteousness and, the number of years' experience -knowledge all of the people we encountered. We highly recommend Ace & A."

"Atlanta Air Authority was great all around, polite, on time, and informative. One of the few places that offered quotes on multiple suppliers. Their prices were the best, the lowest for the highest quality, along with very competitive warranties on their work. They had pride in their workmanship and it showed. Iâ m looking forward to also using them for all my HVAC maintenance."

"Great. Jerry Cobb came by to reprogram the thermostat for us. We were not able to figure out how to get it the way we wanted and Jerry took care of it for us. Cool Air replaced our entire HVAC system about 2 years ago. We were happy with the job and will be having them add a humidifier to the system soon."

"This was my second quote and this company is amazing. Quickly identified the issue, changed the motor, provided a filter and made sure everything was working on one trip within a few hours. The previous company (Air Pros, LLC) said it was unfixable and tried to sell me a new unit over $6k which was a huge scam. Don't go to those guys, work with this family owned honest business. Keep in mind HVAC repairs in many cases are not cheap, I own 3 houses and have paid several hundred or more when an HVAC is old and need repairs."
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.
