"We were very pleased with the quick response, detailed information, professional and courteous staff at all levels. Our old furnace died in November on a Friday. Other businesses couldn't get anyone out to repair and replace it for 2-3 weeks. Ranger had it replaced on Monday for us. This week our electronic air filter quit working. Again we had a quick response with a simple fix at no charge. All of our questions were answered fully and information given about the latest models but with no pressure to buy. We will absolutely use Ranger again and refer our friends and family to them."

"We had central AC added to our home 5 years ago. We decided to get an AC and furnace tune up before the summer. Matt, the technician from One Hour Heating and Air, was on time and polite. He pointed out that our furnace filter had not been changed since 2022. Big oversight by me. Matt explained how the air flows through the furnace and the direction the filter needs to be placed. I marked with a sharpie on the furnace an arrow so I would remember next time. Positive experience."

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.
