"John and Zack from Bama Air Systems were personable and professional as they replaced our old mini split system with a quality mini split. The four other companies that came out before Bama didn't have a clue on what to do. Thanks Bama Air!"

"Jeff, the technician, arrived on time and checked the unit. He cleaned the drain line from the unit and dried out the drain pan and inside of unit. He checked the A-coil, found it needed cleaning, and took pictures with his phone to show me the condition. He gave options for different levels of service and provided prices for each so I could decide which to choose. He cleaned the coil and took more pictures to show me the difference. He also added brackets to hold the air filter in place securely. Jeff was thorough, patient, and answered all my questions. After the service, there was a definite improvement in air flow inside the house. I will call them again."

"Wehby Heating & Air was prompt, professional, and thorough. Within a day, a company representative was at our house, and we were given a quote within hours. Their quote was nearly $2,000 cheaper than the first company we contacted. The repairs were done in a clean and timely manner. The employees were courteous to my family and my pets. After the repairs were completed and the new unit was installed, I was given thorough instructions on how to use the new unit and wall thermostat, as well as detailed instructions on how to register our new unit online. I would highly recommend this company to anyone; homeowner, small business, or large business, no matter what your heating and AC needs may be. They saved our summer and a lot of money!"

"Mr. Coffee is a hero who risks his health daily to help mitigate dangerous radon problems for strangers who call for help. This is a dangerous job with daily high radon exposure and when I asked, he said he is aware of the risks but gets his health scanned multiple times a year. I called Covenant Air back in December after noticing that my Safety Siren Pro radon detector kept reaching alarm. Mr. Coffee came out and assessed that I could probably fix the problem myself by sealing some obvious cracks, especially around some pipes, and recommended the products so that I can do it cheap DIY. He was obviously not pushy to scare people into signing contracts, but actually tried to dissuade me from hiring him right off on installing sub slab depressurization. Although the DYI route he recommended would've been cheaper, I hired him to performs the job. The sealing did bring the radon level down where my detector's alarm didn't go off, but I wanted to lower it as much as possible. He then recommended a passive ventilation route given my reading. The passive ventilation again slashed the radon level in half, but I wanted the radon level down even further, so I ultimately opted to install the fan after weeks of data collection and analysis. He installed the fan so that I could easily turn it off to save energy based on seasonal variations. He is a very personable and methodical person, and prefers to monitor the progress of his work so that his customers don't hastily incur unnecessary cost. You almost never see someone like that in the service industry, and I cannot recommend him highly enough.

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.
