"Our thermostat went out, tried replacing it ourselves and then our heating wasnâ t coming on anymore. Gave NexGen a call and they got someone out the next day before the cold front came through. John came and took a look and found and fixed the problem quickly. He checked to make sure everything was wired correctly on our thermostat, and that everything was running smoothly. He also informed us of some cleaning that needed to be done to our system to help it run more efficiently, and offered the service to get it all cleaned up while he was there. All in all, NexGen was quick, informative, friendly and affordable. Highly recommend!"

"Wow! Extremely timely. I called in the middle of the night thinking I d probably have to call back in the morning...but at 8 am, I immediately got a call from Action Air! In about 30 minutes, he was at my house and working on my AC. In 30 million minutes, he had accomplished the repairs and for less than I had been told by my friends (of what they had payed for similar issues). Definitely storing this business in my contacts and recommending them to friends."

"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 would like to highly recommend Air Rx for the outstanding job they did at our home. Justin, the Air Rx technician, arrived on time and quickly assessed the tasks for him to complete. First, he meticulously cleaned the dryer vent. Next, Justin removed all the air registers, cleaning them until they looked brand new. With the registers removed, he was able to use a large vacuum to reach into the air ducts. Those ducts were sprayed with a cleaner and the unit itself distributed a fine mist throughout the entire system to treat mold, dust and other allergens. When all the duct cleaning was done, Justin vacuumed our entire home to remove the debris that had fallen out during the cleaning process. While he was here, I asked him if he could help us with replacing the original air return register, which is old and battered. He measured the opening, called his boss, who delivered it, and it was installed, too. We have asked our A/C company at least four times for help with how and where to get it replaced since it is an odd size. This is a first rate company!"

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.
