"Jim was very helpful and personable to work with. I had recently moved to the Huntsville area and was unable to connect my wireless printer. There were also some things going on with my laptop that made me suspect a virus had somehow gotten on to it, it was running more slowly than usual, and I wasn't happy with the Win7 configuration I had done when I bought the computer. Jim came in and assessed the problems and we agreed on a time for him to take the laptop and reinstall the OS. He was able to get the wireless connection to work as well. He took the computer on a Friday evening and returned it Sunday evening in prime condition.
A few weeks later I got an error message while reinstalling my accounting software so I called Jim. He talked me through the problem over the phone and I was able to get the program installed so I could use the program.
Jim is great to work with, his pricing is very fair, he is prompt and reliable. I will definitely use his services again.

"What I didn't like, I hadn't had any other problem in my house until I had an air conditioning problem. While, they did take care of fixing most of the stuff with the air conditioning. I did have to pay for the coolant that went into it, that was kind of aggravating, since you know you are already going to pay a $60-$80 service charge for something and the you turn around and think you are covered and find out there are gaps of coverage. We'll fix the part and pay for the labor but everything else is on you. I think outside of price all the categories are an "A". For price I'd give it a "C", because it's not like you are getting complete coverage. I'd use them again if I needed to, I'd definitely consider it."

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.
