"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!"

"Chris responded with a house visit to check my air conditioner mini-split system very quickly. He communicated the problem with the unit and gave me the information I needed to make an informed decision on the repair. The repair parts were difficult to find but he eventually got the unit delivered and made an on-time finish of the repair. The unit works well so far."

"I know there are a lot of good AC/Heater companies locally but Im just speaking from my personal experience with this one. Luis @ LB air came out to our place on 3 separate occasions, free of charge, to assist me with an issue that we had with our unit. He kept coming back and stayed waaaay longer than he probably should have until he found the source of the problem and got it corrected. The service was VERY professional and transparent about his procedures and prices. When it was time to pay I just knew it would be outrageous but I literally have spent more money eating out with with a group of 5 or 6 at Mighty Crab. Again, I am not knocking other companies, I am just saying that I HIGHLY recommend this one. Appreciate ya Luis."

"I had an issue with my computer where it was opening lots of pop ups, ad bars, and windows with ads for games. I had tried several different programs to try to remove it with no luck. I finally decided to call North Alabama Technical Service to see if I he could help. I was expecting to set up a time for him to look at it but he connected to my computer immediately and within an hour had it fixed and running perfect again. Great service at a great price and I didn't even have to disconnect it and carry it somewhere! Would call again if I have another issue I can't resolve myself."

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.
