"FURNACE INSTALL - Phil from L&L Heating & Air Conditioning was very professional and knowledgeable. He listened to me when I stated that I wanted a high efficiency furnace --- he did not try to sell me something that I did not need or want. The crew showed up on time, completed the work well within the scheduled time frame, and cleaned up thoroughly. I have recommended L&L to my neighbors and friends."

"Nate was amazing! He inspected and worked on my homes air conditioning unit. He was so pleasant, friendly, knowledgeable, and informative... he took the time to explain all the work he did and recommendations on what needs to be done in a way that I could understand. He talked about the different options I had on future upgrades/replacements/repairs and their cost without any pressure on buying them NOW... I am so pleased with this experience and plan on using this company in the very near future for some of Nate's recommendations... In addition, Nate refused taking a tip ! Trustworthy & Honest with EXCELLENT CUSTOMER SERVICE SKILLS!"

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.
