"I have used Speer Air for several years for HVAC preventive maintenance at my home. We recently expanded and they installed a package unit to take care of the expansion space. The work was good and they have been back for adjustments as necessary."

"Advanced Professionals was very prompt in sending someone over to our office to assess the issues with our Air Conditioning unit. It was extremely hot weather and having an office full of doctors and staff was unnerving and frustrating. They were able to accommodate us right away and sent over their technician Rabi. He was very knowable and extremely helpful in resolving the issue. He was able to get us back up and running. He was very thorough and took his time to explain exactly what the issue was and gave recommendations on how to avoid this problem in the future. We are very confident in the service provided and will continue to use Advanced Professionals for any future services needed."

"I was very impressed with the service I received. When scheduling the appointment everyone I dealt with was responsive and polite. I had called because our A/C wasn't working and they were able to schedule a technician to come service the unit the next day. The technician (Devin) was very nice and he explained the work he was doing. I had not had the A/C unit serviced for a while (shame on me) so there were several problems. He was able to address them and he also encourage me to get a service contract so we can have the system serviced annual. Overall I was very happy with the work that was done. Thanks!"

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.
