"I had called another service come give me an estimate to fix my AC. That company did not discuss the problem and what caused it, they just wanted to sell me a whole new system. I then called my home warranty, they sent NexGen Comfort Services. After evaluating my AC's situation, my home warranty would not pay due to the unit not being installed properly in the first place. However, I was so impressed with NexGen I asked them for an estimate. Their estimate did not involve replacing my unit but actually fixing the problem. They fixed the problem as well as brought everything up to code. I am more than pleased with NexGen, they are out to fix the problem, not take advantage of the consumer. Without a doubt if needed, I would not hesitate to call them again and would HIGHLY recommend NexGen Comfort Services. THANK YOU to each of the professional employees that was involved with this project!"

"Arrived within two hours of call. Repaired air conditioning unit in less than an hour. Gave important information on the mandate for refrigerant changes which will require the purchase of a new unit. Now I can budget for a new air conditioner and not be blindsided when that day arrives! Good service. Good price. Thank you."

"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!"

"They did a really good work. They had a good pricing. They were really good workers. They were very accommodating to the customers."

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.
