"Ken replaced our water heater. Seems to know his stuff, and it's working fine. He had to take a trip out to get a missing part that he thought he had, but he adapted on the fly and still got the job done the same day only taking about an hour longer than expected. Friendly and capable."

"I recently used this AC service for a small repair on some wires connected to my AC unit, and I couldn’t be happier with the experience. The technician agreed to come out the very same day and arrived within the hour. He made the simple repair, and got everything back up and running fast. The price for an evening service call was very reasonable, especially for such quick and reliable service. It’s hard to find people you can truly depend on these days, but now we know exactly who to call whenever we need AC help. I couldn’t thank him enough for getting our air back on so quickly. Highly recommend!"

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.
