"I received 3 quotes on installing a new 5 ton unit to our house air network was $2,000 cheaper than the # 2 bid and over $3000 cheaper than the other bid. They came when they said and chris was very knowledgeable. We had a new unit installed as well as all new ducting and blown in insulation. I would highly recommend air network in the Weimar area"

"They were great. I hired them to remove old insulation and install new insulation. They discovered serious issues with my a/c duct work. They rearranged their schedule to come back and make repairs to the ducts. They were lifesavers."

"Wetzel's Heat & Air excel right off the bat. On the initial visit, Tim completed a sketch of the room layout, room dimensions, and number, size of vents. Johnny Wetzel performed air handling analysis which they recommended correct duct and vent sizes. Tim, lead installer, and Johnny is two that I trust in this business. The new system was installed professionally and completely."

"There are many things I like about Troyâ s Heat and Air LLC but the top three are: 1) Professional install, 2) Commitment keepers, and 3) Great value. I originally saw their ad on Facebook and felt compelled to give them a try even though I already had a local AC company. Troy and his team came out, fixed issues we had with the main unit for some time, and installed a new mini split. I had already had 3 different people come out but it wasnâ t until Troy and his team came out that the installation looked professional done and safe. Anyway, as we have been remodeling for the past 2+ years we have had lots of contractors out and I believe Troy was probably the only one that really kept his promises to us and completed the job they were hired to complete. Thank yâ all! Hopefully God will provide and I will be able to get the unit for the barn one day!"

"We own a home-based business which relies heavily on our computers operating efficiently. We have had a service contract with another computer repair business for several years. Recently when we were having problems with our computers, we tried contacting our service contractor multiple times. He never responded. Feeling frustrated, I contacted James at North Alabama Technical Services and explained our situation. He instantly came to our rescue. He "cleaned-up" our computers and took care of all the problems we were experiencing. He went above and beyond to help us in our dire time of need. We would strongly recommend James and his company for computer service needs. We have now retained him on a service contract and are looking forward to working with him in the future."

"The service went really good. They were professional and nice. Highly recommend 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.
