"All I have to say is that Absolute Comfort Heating and Air Conditioning exceeded our expectations on the installation of our new Trane heat pump! Alex was our point of contact, and he was very knowledgeable, and courteous. The installation crew arrived on schedule and impressed us with their expertise! Robert, Courtland and Cody got right to work and took out the old system… and then installed our new heat pump. They were all knowledgeable, friendly and courteous… answering any questions we had! One day! We have cool air tonight! Thanks guys!"

"Rhett came out and did a thorough evaluation of all components of our heat pumps. He found wiring that had been connected incorrectly, as well as wiring that was never connected, which was causing our heat to blow cold air (thus defeating the purpose of having the heat on!) He rewired two of the units and added Freon to one that was low, and the heat has been working perfectly since. Rhett is easy to reach, honest, personable, thorough, and makes sure you understand what is going on and the work he is going to do to fix the problem. His pricing is fair, and he gets the job done right."

He Made a through evaluation and repair of my heat pump. He also did service check on my air conditioning and a second heat pump. He gave a complete explanation what services he performed and discussed trouble spots that will need to be addressed in the next scheduled service."

"Josh came early to the appointment, introduced himself and immediately placed shoe covers over his shoes upon entering my home. He was beyond professional and explained everything that he found and the plan to repair the heating issue prior to getting started. He also made recommendations for maintenance but wasn't pushy in trying to make me buy anything extra. I HIGHLY recommend this company and will not only utilize T.Byrd's Heating and Air again, but I will refer them to my friends! Keep up the good work guys!"

FAQs for air conditioning projects in Concord, 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.
