"They took a look at the air conditioner which was not cooling my house. They refilled with freon and then recommended some changes. Price was good. The worker they sent was definitely experienced, he went right out to identify the problem. Pretty personable. He didn't mind me looking at what was going on."

"Oscar was amazing. After determining that the wrong air handler was ordered (not their fault, third party did the quote and ordering) he was able to get our old and broken AC working short term until the right parts (that he specified) can be available."

"Matt and Mike replaced our old barrel type humidifier that wasn't working and replaced it with the Aprilaire fan in humidifier, ran a new water line, electric and rerouted the condensation line to the sump pump. They also upgraded the thermostat and relay panel to be able to control the humidity from t-stat. Everything is running perfectly with home humidity at 46%. Also purchased the elite yearly service plan."

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.
