"I was looking for a qualified repair service on my Trane ac system. I went to Angies List and Clark And Sons and a few others were recommended.I promptly received a call from Andy Clark and I asked about his knowledge on Trane Hyperion air handlers. My unit was showing two error codes. Andy assured me that he could repair my system. He came and diagnosed the problem, replaced two sensors and corrected my problem. Andy was very knowledgeable, fair and honest. The kind of person you want to come into your home. He cleaned and serviced my ac system also since it was installed seven years earlier and never cleaned"

"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!"

"They come out every 6 months and do service on my unit. They check the air conditioning out in the spring and then the heating in the fall. I have been using them for 10 years. They are very responsive. The technicians are very knowledgeable and they are very reliable. They have always been very good with me. I haven’t really gotten a lot of experience in the last 10 years with anyone else. It has been very good."

"TONY HERRIN is our all time favorite heating and air conditioning professional. We've been blessed to have known him for 23 years. He is always thorough and explains all the work he does, while giving us an update on the system check list important for its continued peak performance. When any repairs have to be made, his work is of the highest quality. My wife and I ask for him every time we call for maintenance or service, and we're willing to wait for an opening in his schedule. Horne Heating and A/C recently merged with Quality Comfort Heating and A/C and they are continuing the fine service we came to expect with Quality Comfort. Top notch organization!"

"From start to finish a great experience! Called with no air conditioning yesterday, a Friday holiday weekend. The lady that answered the worked wonders and found tech close by that could come the next morning. I received a call the tech was going to be earlier than expected. Great news on a hot day with no air. The service was efficient and fair priced. Within a hour my unit was up and running again. The sales office followed up right after to schedule a time to look a future options since my unit is getting up there in age. No pushy sales. Professional, quality service. I will use them in the future and highly recommend this company."

"I had another provider servicing my furnace, but after my home warranty sent KS Kamara Heating and Air to diagnos my problem, I learned that the previous provider was not doing what was necessary. KS Kamara Heating & Air, diganosed the problem, show me why I was having the problem, took care of the problem and now my system is running as it should. I then hired KS Kamara Heating and Air on the spot. I was amazed at what was found when he serviced my unit. I look forward to a continue business relationship with this company. May thanks to KS Kamara Heating and Air."

"I guess the price alright. It's about what we paid in Charlotte with another company, maybe just a tiny bit less. But I guess it's the what the prevailing rate is. We had somebody else to do the work, and they didn't do; and we paid them more. We have signed up to use them for our maintenance service for the furnace and air conditioner."

"Reagan called to ask about my issue with my AC, and made time to come by my house the same day. He called prior to arriving and came at the time he said he’d be here. He was professional, courteous and informative. I would recommend him, and will absolutely contact him again for future HVAC needs."

"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 Mount Holly, 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.
