"The sales rep was thorough and answered our questions clearly and promptly. The installation went very smoothly, except for gashing a wall while moving the new furnace in. They repaired the wall and repainted the area. A few days later when the house wasn't heating up as quickly as it should, they sent someone out right away to find and fix the problem, which was actually a ductwork issue unrelated to the installation. Very pleased from start to finish."

"Comfort Advisors is the only heating and cooling company I will call. I woke up to a freezing house with temperature outside in the negatives, and when I called for help, they responded quickly and helped me fix my geothermal system. Having a newborn in the house, it’s incredibly important that they were able to get the heat back on within a couple of hours. Mike has always been so easy to work with and is kind and honest whenever I call for help."

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.
