"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."

"The proprietor, Ryan, was a knowledgeable HVAC experience! My husband and I know very little about furnaces. Ryan was patient and taught us what we needed to know like scheduling cleanings for our needs. He is also available to expand our water system at a later time. Ryan gets a five star rating from us."

Heat pump works great and they were able to direct me to an Effeciency Maine site where I received a substantial discount on the installation, equipment and cleaning plan!! Great company to do business with and will recommend them to family and friends. I will definitely not hesitate to use this company again if the need should arise!!"

"Very well. IAS inspector total gas system (20 years old) and advised that new safety regulations required a shut-off valve at the house regulator which they installed and leak tested. Following this they connected the range and fully tested the installation."

"Jim with North Alabama Technical Services removed some items from my computer so that I could send emails and attend to items I needed to address that day. As planned, the next day he thoroughly cleaned my computer, he also made helpful suggestions while working on my computer. I would call him again if needed and I thought the fee was reasonable."
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.
