"This company is fantastic. I have used them for the past 7 years since relocating to North Carolina and they have always completed the work in a timely, cost effective manner. We have had the privilege of working with the same Service Tech. (David) that entire time. In my experience as a homeowner (35+ years) that is unheard of. David is on time for appointments (or calls is running late or early), quickly responds to emergency heating/cooling situations, and looks for repair solutions that will take care of the issue for the least possible cost. It is reassuring to "know" your tech. and have a good feeling about the job he is doing. We also have an annual service agreement with Duggins. We have two furnaces (one electric and one gas) and two a/c systems. Their annual service fee, in my opinion, is very reasonable. He spends whatever time necessary to do the job right. Our home was new construction and in the first couple of years we had a major repair to the system. Duggins did not do the original install but reached out to the manufacturer to make sure that the warranty work was covered. This may not seem like a big deal, but I was not aware the unit was still under warranty, and would have paid for everything - I do not believe all companies would even check about the warranty. I have no reservations recommending Duggins based on 7+ years personal experience with them!"

"Carl was responsive, friendly, knowledgeable, and honest! I was able to get a same-day AC repair, and he provided 3 options and explained each of them thoroughly. He was truthful and not willing to quickly offer the most expensive repair, which my family appreciates given we have been serviced by several other companies in the past. I am pleased with the service and highly recommend Boyd's!"

"Very thorough technician that properly troubleshooted my AC/HVac system to get it back up and running. The technician explained the problem found, recommended what part(s) need to be replaced, and explained the possible causes of the component failure. Will certainly recommend H&S Mechanical Services LLC."

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.
