"Shaun was excellent to work with from start to finish. He responded quickly to messages and showed up early to work on my a/c furnace to air heat pump conversion. Although it took longer to complete the job due to circumstances out of his team's control, they maintained a positive attitude and got the work done in a clean, professional manner . I would not hesitate to recommend Temp-Rite to friends and family. Shaun did a great job. Hire Shaun."

"I would highly recommend Built Right Concepts. I was looking for an estimate to replace my heat and add air conditioning. They showed up on time, provided an estimate on the spot and negotiated my hot water heater as a bonus to close the deal. I did get two other estimates for the same Carrier equipment and by far they had the BEST pricing. On the day of install Jason & John showed up on time. I requested adding an outdoor faucet when installing my new water heater and they made that happen too. The work done was neat, clean and professional."

"Everything went well. Chris did a fine job with the shelving in the closets; his worker installed a curtain rod that we had trouble installing, and he also replaced vinyl planks in the foyer. They also installed tile flooring in the basement bathroom. All the jobs were professionally done, and we were very pleased with everything."

"Along with installing new bedroom and closet doors, the contractor also installed vinyl plank flooring in our living room, dining room, and bedrooms. He also hung our dining room chandelier, and installed moon lights above our fireplace. His attention to detail in his work was impeccable and he completes the job in a timely manner. I would recommend his services to anyone looking to have work done on their home."
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.
