"My A/C went out and my home warranty sent out a company that said the coil needed to be replaced. They sent me an invoice that was way more than I expected so I decided to get another opinion. I listed my issue on Home Advisor Sunday morning and Shamrock called me within 10 mins. They came out to diagnose my issue free of charge AND knowing that I had been without air for a week already they loaned us a window unit. They came out the next day, put the window unit in and checked my system. Found out that the issue was not the coil, but even if it was the charge was way less than the invoice I had received from the other company. Thanks to Shamrock our air is working better than ever. Very prompt, courteous and thorough. Fixed issues that previous company created. Highly recommend!!"

"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!"

FAQs for air conditioning projects in Kernersville, NC

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.
