"I had been experiencing uneven heating and cooling and high electrical bills for many years. My unit was also almost 20 yrs old and not working very well anymore. I did my homework and decided I wanted a Trane. I contacted several companies for estimates. Air Network as the only company who contacted me in the time frame promised as well as coming out to see what my needs really were. It turned out my duct work was done improperly by the previous owner resulting in my uneven cooling. Air Network answered all my questions honestly and gave me several bids on different brands and sizes before the day was done. I still insisted on the Trane which by brand names is not the least expensive but was still at a very good price. His crew showed up on time during a day where it rained all day. They put mats on my floors and began dismantling my system. Chris the owner drove 2 hours to north Austin to pick up the unit I requested since there were no local Trane outlets and then 2 hours back to Hallettsville. They worked so efficiently I actually fell asleep in my recliner while they worked. By the end of the day I was more comfortable in my home than at anytime since I bought it. His crew were neat and courteous and left my home cleaner than when they arrived. I was so impressed by Air Networks that I will not allow any other company to service my system in the future. There were no extra or hidden costs. The job was done for exactly what the estimate was. I HIGHLY recommend Air Network. This is the first 5 star rating I've ever given a business, but Air Network truly deserves it."

"I was referred to Felipe Castro, owner of Castro Air Conditioning by a previous customer of his. He was very honest, professional, and most importantly knowledgeable about replacing my whole system. He came by at about 11am to inspect and quote us a price, by 2:30pm that SAME DAY he and his crew were here doing what they do BEST. The work took about 5 hrs to remove the old system and install the new. He was very reasonable with his price and the equipment he installed is "top of the line"! Don't waste your time shopping around, I can guarantee you will be highly satisfied with Castro AC!"

"Excellent work. Arrives on time and very personable. Installation of ceiling fans was done professionally. Had ordered one fan that was too small for the room. Was advised what to order and what to order for another room with high ceilings. Sent back small fan ordered two new ones and Don from Enoch installed the new ones. Had trouble with air conditioner cutting out and noticed it was tripping the breaker switch. Don arrived again, diagnosed the situation. Breaker switch was too small for the air conditioner. Installed correct breaker switch and everything running smoothly. *This review was migrated from an affiliated account on Angi with an original submission date of 8/27/2016."

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.
