"I was extremely pleased with both the product and the service that was provided. Joe and his team stayed in constant communication with me throughout the process. One thing I really appreciated was that he discovered that the unit that was installed by the builder was larger than I needed, and therefore was not running efficiently. He explained to me in a way I could understand what the difference was in the sizes and why a smaller unit was actually better for my house. This saved me money, not only on the unit itself, but also on my energy bills, which was a savings I saw immediately. The work was done well and on time, and the follow up service was also excellent. Joe checked in with me several times after the installation to make sure that I continued to be happy with the work. I was impressed enough with the service I received that I hired him to come back and extend my exterior gas line from my barbecue grill to my fire pit. Once again, the work was done efficiently and well and for a fair price. I definitely recommend this company to anybody who has HVAC needs."

"Two years ago Riley Plumbing and Heating replaced the corroded galvanized water pipe from the street meter to my house, so I was very surprised to have another water leak in the back yard last month. Riley Plumbing came out again, and found that the new leak was due to another corroded galvanized pipe that was supplying water to the back yard irrigation system. They replaced this pipe, tying the water supply to the irrigation system to the water line they installed two years ago. Mike Rojas, Luis Ortiz and Aiden did the work in a professional manner, and left the back yard in good shape for re-seeding this fall. (Hopefully no more corroded pipes in my yard!)"

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.
