"This young man was very efficient and communicative. He was extremely conscientious and exact about his work. He was considerate about caring for our home by carefully closing the door and wearing foot covers on the carpet. He installed a window unit in an upstairs bathroom. Did an excellent job. Would hire him again if needed."

"Nick came out, found the problem quickly, replaced the part and had us up and running within 45 mins of arriving. Even hung around to make sure it worked properly. I will use no other company and highly recommend him to anyone."

"Computer did the "gotta send info to Microsoft" but when tried to reboot it ran through automatic repair without success. I did all the alternative without any success. He came and picked up the hard drive on Tuesday and returned it on Saturday. Fortunately he was able to "restore" without any data loss. Very happy with outcome."

"I called Dallas within minutes after I posted my request on Home Advisor. He volunteered to come out that afternoon but I was at work so could not meet him that day (12/17). He came in a timely manner today (12/18). He was friendly and quickly went to work on our furnace. He worked the entire time he was here, wearing a mask & keeping social distancing. It is so nice to have heat again!!!!!! I would definitely use his company again should we have heating or A/C problems. I feel his rates were appropriate. As retired 80 year olds we have a difficult time getting work done around the home. I am so impressed with not only Dallas but Home Advisor. This is the first time I have used your service...but not the last time. Thank you Dallas and Home Advisor!!!!!!"

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.
