"Professional personal and prompt. I chose Eric and his company legacy to inspect and service my mom's furnace because of the company size. Legacy is a small company in comparison to the local big guys. Eric returned my original call very quickly and returned followup call just as quickly. We booked an appointment for Saturday at 8 AM and he showed up perfectly on time. He explained in plain English what he would do and why. I checked in once while he was working and he took time to show me the video he was taking of the inside of my furnace. The job took about 1 1/2 hours. Upon completion he showed us a very detailed inspection report and gave us a private portal link to view your photos and report online. His price is very competitive as well. We had only a routine check up done but because my great experience I will recommend Eric at Legacy for any HVAC needs you have. Legacy will now be your go to for heating and cooling of our home."

"Apex responded to my call immediately and sent out a technician to give me a quote. I accepted the quote and they came back a couple days later and installed the new thermostat and everything is working great. The young man that installed it was very professional and very knowledgeable. Thanks."

"Tech was very nice and helpful. He gave some tips as far as getting the best use of our A/C and keeping our house cool without suggesting we replace with a new A/C. We had to pay after hours pricing because it was a weekend but since we work past 5 during the week we wouldn't be able to avoid the extra charge. Would definitely hire again. Our tech was fantastic."

"A quick and Professional install. These guys were awesome!"
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.
