"I would highly recommend this company, they did a great job and if I had questions or problems they were right there and took care of it quickly, at first I was only going to get a furnace but the sales person who came out said it would not cost much more for air so I went with that and don't regret it since we were using window units which was a pain every year, I am enjoying my furnace through the winter and enjoying this air as it gets hotter, thanks Hamilton! I will be calling soon to get pricing on something else I need done"

"Adam squeezed me in the day before Thanksgiving when my furnace started leaking. He was thorough, kind, and reasonably priced. He added a safety shut off valve, and was even willing to come back when the gas company came by to make sure all the leaks were secured! What could have otherwise been an extremely stressful ordeal was quickly resolved, thanks to Adam!!"

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.
