"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."

"I had my refrigerator needed fixing and looked for a budget option and saw this new company with almost no reviews but I still trusted my work with them because of the quotation being cheaper. And they did a good job fixing the compressor and were very timely and professional in their service. Much appreciated!"

FAQs for air conditioning projects in Fremont, NE

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.
