"They installed central heating and air in our home in 2025. They were efficient, did a excellent clean up, and friendly. They checked in a week after to make sure we were satisfied with the system and if we had any questions. We are extremely satisfied with the new system. The controls are easy to work and the system is very quiet and efficient."

"I was fortunate to receive service on the same day I called. My issue was difficult to diagnose, as many have tried before. They were willing to step in and try to resolve my issue for good. They were successful at their first attempt. I am grateful to Guerrero Heating & Air this Labor Day weekend of 100*F+ weather."

"Ken is like a savior. He is a very hard worker. Very knowledgeable, kind and caring. In 2 and one half hours, he took apart my gas wall furnace and completely cleaned it. He replaced the thermocoupler. Bell Brothers had come out and didn't even take the time to look to see what was wrong with it and said for $2000 they could fix it and for $4,000 they could replace the unit. Ken was very concerned about the safety features of the gas wall furnace and had me place my carbon monoxide detector closer to the unit. In the future I will probably have him install a mini split heater air conditioner. My dad was a Ken."

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.
