"Best price for unit and installation of the companies I looked into, but customer service left something to be desired. Took a very long time to get someone out to install the new filter set up at the air intake, with poor communication on their part. That part of the job was done poorly and had to be redone at my insistence. Also had the red warning light come on. Called about that and no follow through. Again. Really wanted to like these guys, but unimpressed with the experience."

"Shimon is exceptional! SO quick to respond to my initial Angie's List message and answered ALL of my questions! Per my request, he text me his eta the day of cleaning and arrived right on time! He walked me through the entire process, explained what needed to be done & why, then got to work! He is extremely professional, thorough, and kind! He wore protective booties or socks each time he stepped inside, and he cleaned up all the mess- including the dryer lint in the bushes outside! I got before & after photos and videos, too! He treated my home with respect inside & out and was SO careful with my kitties around! I enjoyed our conversations between the noisy parts of the job, too! I HIGHLY recommend StarDucts and will be calling them annually for dryer vents and as needed for air ducts! Thank you Shimon!"

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.
