"We initially had another AC company come out to service our A/C as it was not working properly. They came out 2 days did some stuff but were unable to get the system working properly. We then called 72 Mechanical to come out and they were able to get the system back up and running within 2 hours of coming out. They came out when they said they would; were extremely professional and talked us through the problem as they were fixing the problem. I would highly recommend this company as they are professional and knowledgeable"

"Efreen and co. Came out within hours of my initial call and saved us. I had reached out to a bunch of a/c companies but these guys were honest, on time and very good. Luckily for me, this was only a fan motor needing to be replaced but sine my house (and unit) are about 30 years old, I’m expecting a full replacement soon and they will be my first call."

Hello John Wright here . I am available for all HVAC and refrigeration needs.
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.
