"I called to set up a time for getting a quite for cleaning my heat =pump ahead of winter. He came over and did my heat pump PM and inspected the air vents in my crawl space underneath the house. I was shocked when he showed me the pictures. He then worked up an itemized quote to cover needed repairs. I felt like he gave me a fair estimate and was even open to working with me on the cost. We set a schedule for him to start. He started and finished the project as scheduled. I love how he works and would highly recommend him to anyone needing heating and air system work done. I will use this company definitely for future projects"

"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."

"My technician Alex Thomas completely saved my account with BAHP. Originally, I had been incredibly displeased with the company because of their customer service, or lack thereof. Depending on how my appointment went, I had already decided to cancel my account with BAHP and was in the process of looking for a new company. However, when my appointment finally went through, I was able to work with Alex, and he completely changed my mind about the company. He was not only quick, skilled, and thorough, but also friendly and respectful; he even loved on my dog! He’s also incredibly knowledgeable about all of the ins and outs of air-conditioning and made it easy for me to understand the processes without being patronizing. I cannot recommend him enough and because of his service, I can also recommend the company. While it’s clear that the phone customer service reps need additional training or restructuring, Brothers’ technicians are SUPREME. I vouch that we give Alex a raise, a promotion,"

"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 called GSM inquiring about their HVAC and insulation services. I also asked if I could have someone perform a Manual J load calculation (surprise to me, the Manual J calc was free!) as I felt that my existing heat pump was sized too small for my home (2.5 ton dual-zone single stage heat pump for 2200sq ft 2-story house). We agreed on an appointment time, and they sent Kelly out to my house. Kelly was very nice and professional, and did a thorough job explaining what all could be done and what my options were. Due to having so little room to work inside of the mechanical closest, you would have to remove the air handler completely just to wrap all of the duct work. Since I would be removing the old air handler that was 8 years old anyway, I decided to replace the entire system with a new Amana 3-ton 18 SEER dual-zoned heat pump. Kelly also told me they could seal up the hole & the mechanical closet so that hot air could no longer enter that space as well. I agreed to their quote, and they came out a week later (it would've been sooner but GSM wanted to make sure that the new system was designed properly, so they had to architect and design the layout of the new equipment to fit the small space) to do the work. Owen and Jason came out to perform the installation. They were both very professional & thorough, and they did an excellent job with the swap out & installation of the new heat pump. When GSM told me that it would take two days to do the work, I was prepared to be miserably hot trying to sleep at night with no air conditioning. Not only did GSM bring a portable AC unit for me use that evening so that wouldn't be the case, Owen and Jason actually got the heat pump wired and working the first day so I had full AC that evening, and the portable unit wasn't needed! They also insulated the attic space & mechanical closet with spray foam and foam board so the hot attic air will no longer be an issue. All in all, my experience with GSM has been great! They've been easy to communicate with throughout the entire process, they did an excellent job with the installation of the new equipment, and now I can rest easy knowing that everything has been taken care of!"

"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."

"I felt taken care of! I reached out the night before indicating that our furnace was not working. I received a text message and a voice mail from the owner of the when I woke up. He seemed to care that we got our heat back asap. I reached out to him and he sent his tech Josh out to help us. Josh found the issue, found the necessary part, after at least one lead, got it installed and my family is warm again. I would definitely recommend T. Byrd Heating and Air to snyone that asked!"

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.
