"We had a technician named Jeremy come out to service our AC because we were hearing some noise coming from one of the vents, as well as to perform our routine maintenance since we’re members of their maintenance program. He did an absolutely great job! Jeremy was very professional, knowledgeable, and helpful. He went above and beyond to make sure everything was checked and taken care of, and he even took the time to show me how to properly change the filters myself. I really appreciated how patient he was and how willing he was to answer my questions and explain everything. It’s always nice to have someone come out who genuinely takes pride in their work and makes sure the customer understands what’s going on. We really appreciate the great service from Jeremy and would definitely recommend him!"

"They're super. They show up on time. If they're not going to be there on time, they call and let you know. You get the same guy every time if possible, so he knows your heating and air system and knows how it works."

"Rosendo and Eduardo did a great job. Completed the install with precision, were very neat and clean. Would recommend Allgood and this team to anyone in need of AC services."
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.
