"Nolan and Nate did a difficult job. They replaced my 1989 furnace with new and installed a ac/heat pump. They needed to mate the new slightly larger unit to existing duct work. You can't tell it was modified. The new outdoor unit is also first class. I would not hesitate to recommend them for any job. They are knowledgeable and.work their ask off."

"My 20 year old furnace died on a cold Thursday evening and I got online to find a company to replace it. After entering my contact info, I immediately received a text message from the company's owner, Casey, making himself available for me if I wanted to talk by phone. I had him call me, and he checked in to see what the problem was, what I wanted to do, and to be sure I had heat for the evening. He even offered to drive space heaters to my home if needed, even though he was at least 45 minutes away. He then scheduled to meet with me at my convenience the next day to look at my home and discuss options. During the meeting, Casey was very personable, knowledgeable,and professional about the products and services his company offered and helped me design a heating/air conditioning system to replace my old, inefficient furnace and wall a/c and insulate existing ducts. He also referred me to my utility company to see if rebates were available, which there were. The workers who installed the products were pleasant, professional, and skilled and ensured that their work met the city's requirements so that I was eligible for the rebate. I am very happy with the products and services I received from them and would recommend them to anyone having problems with their heating/air conditioning units or looking to upgrade to more efficient systems.

"Me and my wife were interested in adding an air conditioner to our home and replacing our furnace as well. We had Shawn from Ares Comfort Systems came to our home and I was impressed. He was very knowledgeable and took the time to answer any questions we had. It was nice to have a contractor who does not pressure a sale and makes you very comfortable to be around. Once we hired Ares Comfort Systems they had our new system installed very quickly. Let just say this company show you how others should be. Could not be happier"

"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."
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.
