"Mario was quick to come out and assess the work needed, was able to schedule me in very soon, and did a thorough job installing the extra outlets. Was very pleasant (and so was Amber, the receptionist!) and I will be hiring Allied again for my electrical work."

"The diagnostic evaluation description changed from my purchase date to the appointment so the service was not what I expected.
I hired the company to seal my ducts. The price was reasonable but on the date of the appointment, only a portion of service was performed and the time of the appointment was not as scheduled. The remainder of the service was rescheduled when I called the company. The computer that shows pre and post duct sealing leakage was on the fritz. I was supposed to receive a copy and have requested this multiple times. I still have not received this.The servicemen are very professional and seem quite competent. The schedulers, receptionist, business office end of things is atrocious.

"Over the years, I have had some harrowing experiences when I have faced computer malfunctions. Just the thought of another telephonic tech support marathon made me cringe. Until now. This was the most pleasant computer repair encounter ever. As I sat comfortably in my recliner, Jim worked his magic on my computer and taught me a few things while he was doing it. Not only does my middle-aged computer run like a teenager again, I can surf with confidence knowing that he is just a phone call away. Before you go buy a new computer (as I was about ready to do), call North Alabama Technical Services. You will be glad you did!

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.
