"I had originally called another company when my AC started blowing warm air. They came out and checked the unit. They found that the coolant and Circuitry were fine. They next checked the blower. Afterwards, the tech told me what he thought the problem was, but it would cost $1400 to find out. Then I called Blanton. Eddie came out and checked the coolant and circuitry, which were fine. He then checked the blower. After he took the panel off it took him about 3 seconds to find the problem. A switch had shorted causing the heat coils to come on. Essentially, the unit was trying to heat and cool at the same time. He replaced the switch, cleaned the blower fan, the coils, and serviced/cleaned the outside units all for less than what the other tech thought the problem was. I will Continue to use them in the future."

"Our entire heating and air system failed. We called JLHVAC and electrical LLC. A technician responded within 30 minutes. He diagnosed the problem and explained it to us in terms we could understand and trust. Our system was aged so we opted to have the heat pump and air handler replaced. Joshua Long and his team replaced all of that plus a new digital thermostat the next day. The total price was a few thousand less than what we expected to pay. If there were more than 5 stars to rate with, we would give more stars."

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.
