"Another service came out and said I needed an $800+ fix. I called Aire Serv to get a second opinion and they not only stuck with it until they fixed my AC, (it took a couple Of visits but they only charged me for one) they did it without needing the expensive part the other one tried to sell me. They were very responsive, helpful and educational"

"I couldn't decide between a liquid cooled or air cooled generator at first. I decided on the liquid cooled so hopefully, there will be a lot less maintenance on it. It took about 2 weeks for the equipment to arrive, but it was installed and running quickly when it got here. The sales appointment was about as easy and low pressure as it gets. I'd call ATS again."

"The most important thing is that can call on him and he will schedule you as soon as he can, even the same day if possible. I have used his services at my daughterâ s house to repair an air conditioning system also at my home for shower repair & just recently to look at my fatherâ s hot water heater. He evaluates the situation quickly and has the tools on hand to make the repair or can obtain them quickly. He does not leave you hanging for days while he works on other jobs. He does not leave until the problem is solved. I have dealt with lots of repairmen in trying to keep my old Midtown home maintained, but have never had met someone like Mr Fixit. He is knowledgeable, fast, reliable and his rates are reasonable. He remains topmost on my list to call FIRST for any & all future home repair 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.
