During my spring AC service, the tech found mold in my HVAC ducts. After a little study, it became quickly apparent the scope of the necessary remediation work was beyond my capabilities. I talked to several companies, did more research, and although IES was not the least expensive, their recommendations as to what needed to be done were by far the closest match to what I had be able to learn about the problem on my own. They did the job in one day; were professional, friendly, and helpful; patient with my questions, and left the house as clean as when they arrived. Once the work was completed, they e-mailed me before and after pictures of the inside of the ducts, which showed a dramatic improvement. They even arranged for me to get a $190 rebate from Duke Power, something I had never considered. I was very pleased with IES’s performance from the time I contacted them through the end of the project. I am also happy to no longer have to worry about potentially dangerous mold spores being blown about the house and would definitely recommend IES to anyone with similar mold problems.
