"I hired Nathan's Air Conditioning....he made an appointment with me for 9-9:30AM..he finally arrived at 3pm with a girlfriend. The work got done more than a week later as a part needed to be ordered..and I got a bill from Comfort League saying he was the technician!!! So he really doesn't work for himself after all!!! How does this get by Home Advisor??? He also charged me $30 travel charge.... I thought he was Local? According to you. Also He quoted 5 lbs refrigerant....he put in 8? I won't use your services again...you don't know who to you are recommending"

"We were looking for a mini-split in the garage & dealing with some other issues as well in the house. As I have some experience in this area & I kind of had an idea what was going to be required. I reached out to a few different contractor's. They responded immediately. Came to our house, looked things over and gave me my options. Ultimately I decided to replace 2 air handlers & install a mini-split in my shop. This is the third house I have had to do this in over the years. Top notch service before & after the install. Couldn't be happier."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

"It was wonderful. I spent quite a bit more than the big deal and it was for an additional I can't remember what it is called. The air duct cleaning was great and then when we talked about this other addition to the system I went along with it because I have animals in the house and I have bad allergies and I wasn't sure after I got it, if it was good investment since then I have changed my mind, it is an excellent investment and it repaired my air completely and my health is much better from having it. I would use them again."

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.
