"couldn?t believe what a professional company you are, and coordinating a completely dust, free and clean environment after they were done. There was not a speck of dust in my garage, or my wife?s bedroom in the Lawn didn?t have a scrap of wire or a piece of paper on it truly commendable. I want to think Coast to Coast heating and air conditioning for hiring. Such great employees who took great care in their work and did such a great job. Thank you COLIN Adams The villages, Florida"

"Had service star Air & heating replace a 5 ton and 2.5 ton and two air handlers that had gone bad. Louis Ratti told me it would take his crew about 8 hours to completed the job from 9:am to 5pm. The crew got there on time and started to work right away. They were professional, courteous and proficient. There was no guessing to what they had to. They were good I say better than good. By 2:30pm they had both systems up and running and the work area clean and spotless. Not only that, I asked if they would connect my phone to both thermostat and with out hesitation they did it. I was very highly impressed. Thank you Louis for sending the right crew"

"I upgraded our home thermostat to one of those smart types. Originally I intended to do this myself with the QR Code instructions but the plug in thing in the back was a little too much for me. The process was seem-less, and the turn around time was quick. Air Serve came out quickly and got my thermostat replaced."

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.
