"Barkley Heating and Air Conditioning did an outstanding job with the installation of our new American Standard HVAC system. We purchased the unit from them at a very competitive price and we could not have experienced any higher professional manner in which Logan Barkley and his associates (Aaron and Derrick) provided us. From the time of the assessment of our needs until the unit was installed the service was outstanding! They were very impressive from the beginning of the project until the completion. They were prompt, courteous, and very respective. If it were possible to give them a rating of above 5 Stars, I would have given that rating to them! Any future HVAC needs we have will be provided by this company. We highly recommend them for anyone needing an HVAC system."

"They had to send another plumber out (who was well qualified), to fix a problem that was not addressed by the first ones. I thought it was a major problem, but it ended up being a minor problem. If not for this, I had rated them 5.0. They were very courteous and respectful. I recommended them to some friends of ours, and they were satisfied with them also."

"Drew and Lauren did great. Good people. Will use again."
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.
