"I was extremely pleased with the experience, customer service, and professionalism shown by Stacy Ferrell at Mid Tenn Mechanical. We called him because our central air unit wasn't working and he got it going again. The next day something else went wrong with it and Stacy came right back out to the house. He kept in contact with us to let us know when he would be arriving at the house. On a scale of 1 to 10 I would rate Stacy an 11! Thank you for the great work!"

"I worked with Jon a number of years ago where he was the main person in charge of maintaining our companys HVAC along with extra service calls that popped up. Jon always checked in with us upon his arrival, letting us know what he will be working on that particular day, checking in again letting us know that he was finished for the day and when he plans to return. Jon also always took the time to explain the WHY and HOW anytime I inquired further so I could get a full understanding of the problem and what we can do to ensure it does not happen again. He is very knowledgeable and takes great pride in his work as well as sharing that knowledge with others. I would highly recommend anybody to try out Jon and Blue Collar HVAC. You will not be disappointed!"

"The owner of Apex Residential Services and the men working for him were on time and professional. I was given the choice of appointment times that fit my availability. Apex kept the set schedule. Very proficient and knowledgeable in their work. Communication is phenomenal as they explained everything from what they were doing to why and what they were looking for. The owner worked with his guys instead of standing around or giving orders. Would highly recommend Apex Residential Services for maintenance, service and repair of your system. Would highly recommend for replacement also. Apex tells you the truth and facts and then gives you options."

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.
