"The technician cleaned and calibrated the air conditioner. He pointed out that we had a part that was aging and could possibly fail at any time. He asked if we wanted to replace it. We told him to do what he needed to do to get the air conditioner working at full capacity. He quoted a price of $132. After checking our account, he returned to tell us that the part is covered under the 10 year warranty. He was very thorough and meticulous with his work.
We have dealt with Duggan for 8 years and had our unit serviced spring and fall each year. The office always communicates with the customer and let you know when the technician is on the way. During the eight years, all the technicians were knowledgeable, professional and  are always very polite. They wear shoe covers when in the house and leave their work area clean.
Highly recommend Duggan.

"We've been using this HVAC company at our restaurant, Curry and Noodle in Winston-Salem, and we couldn't be happier. Running a busy kitchen means our heating and cooling systems take a real beating, and Chris has been nothing short of amazing. He shows up on time, communicates clearly, and always makes sure everything is running perfectly before he leaves. It's rare to find someone who treats your business like it's their own — but that's exactly how Chris makes you feel. Highly recommend to any business owner in the area looking for reliable, honest HVAC service!"

FAQs for air conditioning projects in Lexington, 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.
