"Quality Air has been my go to company for 10 years. They’ve helped me keep an old unit running without having to replace the whole thing until it was time to replace it. They’ve always responded quickly. All of their employees are very professional, helpful, kind and follow through."

"Air today got me fixed up after my AC unit stopped working 18 months after install. When contacting the company that installed the unit, they openly admitted that the unit was installed incorrectly which caused the failure. After quoting us a seemingly high price to fix it, we looked at other options. We contacted Air Today and they got us fixed up quickly for a fraction of the cost! Not only was the cost better, the techs that came on site were knowledgeable and kind. Mark and Keith were thorough in explaining the issues and patient in helping us understand the needs. They recommended several different options to fix the issue at varying price points. The techs were respectful of our home and were careful not to make a mess or track dirt inside. We work with contractors frequently. Mark and Keith were top tier. All four Air Today employees we talked with through the process were helpful and easy to talk to. Would highly recommend Air Today to family and friends!"

"We wasted hundreds of dollars with Carolina Heating and Air, who failed to diagnose/fix the problem. One trip from Easy Air and they identified the problem (which was obvious and insane that it was missed) and fixed it for a totally reasonable price. Better yet, they came out for free. Upon hearing how bad of an experience we were having with the other company, they offered to come for free to give a second opinion. Carolina Heating and Air came out 4 times, and wanted to do thousands of dollars of air rebalancing and insulation installation. Easy Air found the problem and fixed it in a single afternoon. We signed up for their membership, and so did a few of our family members and friends. Highly recommend."

"Danny I. quickly found our issue and got us back to cool air."
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.
