"Our AC went out in the middle of summer and I called to schedule an appointment and they made it out the same day! They were very professional and completed the necessary maintenance extremely quickly. We had air again by the end of the day. It’s also one of the most affordable places we’ve ever used for our heating and air maintenance and repairs."

"We just had a full HVAC system installed by Ace & A, and couldn't be happier. Every step of the process was excellent from the initial repair call and scheduling, working with sales on a new system consult and the system installation experience. Because we were without air conditioning, they worked hard to get us in and scheduled a Saturday. We appreciated the professionalism, courteousness and, the number of years' experience -knowledge all of the people we encountered. We highly recommend Ace & A."

"I had trouble with the AC about a month after they did an annual service and replaced the capacitor. The system locked up and they came out and I watched as they pulled an obviously old, worn, and burnt, electrical part out next. They replaced that part for the cost of the part and waived the labor as it was so close to the last service. The system is old and they were finding parts that were reaching the end of their life and replacing rather than trying to sell me a whole new system but let me know they would be there if I decided I needed a new system. Fast service, pleasant and knowledgeable personnel."

"Our central air conditioning unit stopped working on a weekday afternoon and the indoor temperature quickly rose to 85 degrees. I called Ragsdale's emergency service after hours. A real person took my information and a service tech called me back within 20 minutes to say that he would be at my house that night. He showed up on time and was courteous and very professional. My unit is 18 years old and had not been cleaned in several years. The tech replaced the capacitor and fan motor, added coolant, cleaned the coils, checked pressure and performed several tests. Repair and clean up took about 90 minutes. He explained to me what he was doing on each step, told me the available repair options and their costs, and gave me pointers on how to spot a faulty unit. Our A/C now blows out colder air than prior to repair. I was very happy with the service and would definitely hire them again."

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.
