"Dean and his team did in excellent job in installing my NEW HVAC system. I had been nursing my old system for the last couple of years. I finally went to the most trusted HVAC company that have worked with for years. The new system chills my first floor down in minutes. I should have done this sooner. Thanks for the all the folks that did the work and the professional staff in the front office and Sales."

"The company is fantastic! I had both full systems installed (condenser and furnace) after one of our units broke down. Jeremy came out to give me a quote and was extremely kind and professional. He made observations about changing some configurations in order to help with airflow and cleaner air. They worked us in early since they knew we were down a system in the heat. Two gentlemen worked diligently to get both systems done ahead of schedule! After the system was installed I had some things I wanted changed with airflow and someone came out the next day to address my concerns. Bethany in the office is extremely helpful and responsive as well! Great team and will use them now for our yearly maintenance too!"

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.
