"Just had my first service check up on my heating and air conditioning unit. As was the install the scheduling was easy. The technician called prior to arrival. I met him at the door and he explained everything that the service included. Then he went about his business. The report was concise and I am extremely pleased with his professionalism and manner. I highly recommend Maynor for your installation and service needs."

"I called the Cape Fear Air Conditioning & Heating's Fayetteville location last Thursday and the person who answered the phone and scheduled the appointment was nice, and thankfully was able to get a technician scheduled to come out the next afternoon. The technician, Jeff, arrived on time, was professional, and was very nice. The technician was A+ and I would highly recommend Cape Fear A/C & Heating. I would definitely call them for future services needed and I appreciate the great customer service. Thank you! :)"

"I put in a request for a heat pump that wasn't cooling correctly. Raymond called me quickly and was able to come out the next day. A complete check showed we needed a whole new system. He showed us the mold and fungus growing in the condenser too! He gave us options on the brands with their respective prices. He was able to come back two days later. He finished the job in 1 day including building a cement platform for the condenser unit and installing a u/v system to keep the mold from growing again. Our new system works great and we have already signed on for him to do the yearly maintenance on it. I highly recommend RPS for all your HVAC needs."

FAQs for air conditioning projects in Cary, 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.
