"This was my first time using Cardinal Heating & Air Conditioning, and it was a fantastic experience. I received a phone call asking me if I wanted to schedule my annual air conditioning check, and when I said yes, the scheduler informed me that she could have a technician come out that day. The technician arrived within a couple of hours and did a thorough check. Everything checked out, and I am ready for the hot summer months."

"My furnace quit during single digit temps. I talked to the owner at 9:00 am and he was at my house to give me an estimate before 10 am (the morning after a snow storm). My new furnace was up and running before noon the very next day. The techs were great - knowledgeable, courteous and even wiped up water the spots their boots left on my floor! I highly recommend JB Mechanical!"

"Jacob from Southport came out for an on-site inspection of my furnace. He inspected the unit and ran a full set of tests for functionality. I received detailed answers to all my questions, and it was overall a great visit."

"We tend to try and have the heating inspection and the air conditioning every year. We don't always quite accomplish that and we've had other people do it but I thought their prices were fair. They were prompt in getting here and answered whatever questions I had. It took them about 2 hours to do the work."

*** I have recently added the Nashville area to my service coverage. Since I can do most of my services remotely with you over the phone, I am hoping to eventually open up to larger markets and help people from having to take their computer in to get it fixed, if it has internet access, I can usually fix it over the Internet. Just trying to do more to help my Angies List customers!!******** I am a sole proprietor that works out of my home. I am my only employee, but I have over 20 years experience fixing computers, and providing superior customer service. I work on a flat rate service, and don't charge by the hour because I feel it's important to educate the customer on what the issue is/was, and how to avoid it in the future. I feel that local service companies (my competition) have been overcharging customers for years. I offer a first time customer discount of 10% but I will offer 15% off for first time customers referred by Angies List. I've lived in the Huntsville area most all my life, so I know the area very well. I will never use a subcontractor as I am very picky about making sure that if my name and company is associated with something, it will be the best experience my customer has ever had, and using sub contractors won't ensure that, so I prefer to do all the work myself. Lastly, I should point out that I am a former offensive lineman for the University of Southern Mississippi and was Brett Favre's center his freshman year at Southern. I went on to play for Tom Landry in his last year, but gave up pro football early on to pursue my passion of fixing computers. If I didn't have bills to pay, I would do this for free because I love it! If you have a computer problem, I promise you that you couldn't find a better technician that will care about you as a customer, and not about the bottom line. I am always available, but don't always answer my phone, but if you leave a message, I promise to back with you as soon as possible...and figure out how to get your issue resolved in a quick, efficient and economical manner. Thanks so much for reading my ad, and I look forward to working for you!


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.
