"I have nothing but good things to say about Mr. Davis. I have hired him for several projects. He has repaired French doors and my backyard fence, installed a door threshold, and installed a system in the garage where the car would not hit a pole in the garage. He also repaired an antique chair and installed rails for stairs. Mr. Davis does very good work; he is punctual, very neat, cordial, easy to work with, and offers fair prices. I have recommended Mr. Davis to several of my friends. You cannot go wrong by hiring Mr. Davis."

Albemarle is the HVAC service company to turn to when you need reliable services. We are on a mission to be the first-choice company for all HVAC needs in Charlottesville, VA. Call us when you're experiencing a problem with your home's heating and cooling unit. We have trained and experienced HVAC technicians to handle all your common HVAC needs, whether you need a new system installed or you need repair services for your old HVAC unit.\n\nWe have been servicing the Charlottesville area since 1988, and our technicians are familiar with all brands and models of AC units.
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.
