"From the moment we inquired about services to job completion, we had a great experience working with Air Quality Concepts for our HVAC air duct and dryer vent cleaning. The owner Charles was incredibly prompt with communication and took the time to answer all our questions about the cleaning process prior to scheduling. We were so impressed by how personable, hard-working, thorough, and efficient our technicians Austin and Michael were when they cleaned our two HVAC systems. They were very attentive to the issues we have been having with our indoor air quality as we navigate mold remediation and health concerns. The company’s customer care was genuine and so appreciated, and the cost of services was very reasonable. We already feel more comfortable in our home knowing we are breathing cleaner air! I highly recommend Air Quality Concepts if you are looking to improve the air quality of your home!"

"Tracy and Darren are excellent workmen for a great value. We had the best experience with Carolina Comfort Air Inc with these two workmen replaced our HVAC. Our response time was excellent and the job was completed within 24 hours. Tracy was very knowledgeable and teachable about our new HVAC. Definitely, would recommend them to others."

"Air ecperts technician Mark provided a thorough and honest assessment of 1) the condition of my hvac system and 2) determined the source of a separate issue related to a running toilet. Most importantly he confirmed a suspicion i had with another highly rated hvac/plumbing company. This other company (Streamline Services, Plumbing, HVAC & Electrical) stated a few months earlierbi had growth in my ductwork and of course suggested follow up work costing over $1,000. However, since my hvac system is about 3 years old i was of course suspicious and contacted Air Experts which I use to service other rental properties i own. They confirmed with pics that there was absolutely no growth in my ductwork or any other component of my hvac system. This alone gives me confidence to use Air Experts for my other rental properties going forward. I will no longer being using the services of the other hvac company."

"After numerous "pros" came to repair my HVAC system, I always got the same response....you need a new system for 8.5 to 12.5k. What they don't know is I know enough about these systems to know the cost of parts and how the system works. So when the "technician" shows up and says they don't know which of the 5 parts was a problem, I'm skeptical. I just don't want to fix everything myself anymore. Comfort Monster is different. The difference is their technicians do not work on commission. Repairman from other companies get paid when the customer has to buy a new HVAC system, giving no incentive to fix anything. Comfort Monster technicians take pride in solving the puzzle of why the machine isn't working. I have two systems and when they inevitably have a problem, I'm calling these guys. Dude even gave my little girls Comfort Monster plush toys and they carry them everywhere!"
