"Freedom Air Mechanical did an amazing job with replacing my boiler. I had 5-6 people come out to give me opinions and Craig was the only one that really took his time to help me find the best boiler for my home. He was very responsive, answer all my questions and concerns, and very importantly I knew he was honest. Out of all the potentials companies I considered, Freedom Air was the only one that gave me options and tried to help me save where I could. I would recommend Freedom Air Mechanical to my family and friends all day."

Patrick got back to me promptly, was very receptive in answering all of my mother's questions, and was able to start job within a couple of weeks from first call.

"Eric did a fantastic job installing our new bathroom fan. He was courteous, honest, and clearly knows his trade. The fan is quiet and works beautifully. It’s such a relief to find someone reliable and skilled. We will definitely use Angell Electrical again! 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.
