Edgar Mejia founded Nu-Air Heating & Cooling, LLC after more than 20 years in the HVAC industry. As a Navy veteran, Edgar built the company on the same standards of precision and accountability he carried through his service, and that background shapes how we approach every installation.
What to Expect During Installation
A ductless mini-split installation begins with selecting the right placement for the indoor unit and outdoor condenser, then running refrigerant lines and electrical wiring between them. Our technicians are licensed and insured, and they treat your home accordingly: boot covers go on before we enter, and we leave the space clean when the work is done.
Once your system is running, the right maintenance plan helps keep it that way. We offer maintenance plans tailored to your specific equipment and how you use it, whether that’s a single-zone setup in a home addition or a multi-zone system serving a light commercial space in Covington or Madisonville.

“Have used other services and this one is far above the rest”Bea D.

“I am a meticulous DIY handyman myself and I was completely satisfied with the work that Edgar did for me. He replaced the evaporator coil, transition, plenum box and first 25 ft of duct for the ground floor system. He also lined (and sealed) the return air passage. While he made several work scope additions during the job, Edgar made no attempt to increase the agreed upon price. Edgar approached my project as if he was working on his own system. I highly recommend this HVAC contractor.”Marvin

“I have been using him for 25 years and he is spectacular! When you have Edgar come to your house, he is thorough, everything will be done, and he checks everything. He is incredibly professional, extremely knowledgeable, and so trustworthy in the sense that you are well taken care of. He works his heart out! He is absolutely wonderful. When he comes into your house he doesn't come in as a stranger he comes in as a friend and I'm not that easy to please. He will teach and explain to you the workings of your system. He is absolutely committed to what he is doing and his craft and his work ethic is extraordinary. I have full confidence in his abilities because he always performs at the highest level.”Jackie

“Professional, knowledgeable, fast, great communication and the best price. If you want great service this is the place.”Jeff M.

“Edgar, the owner, came out originally to diagnose one of my A/C units not working. He quickly diagnosed the problem as a damaged circuit board, which he was able to retrieve from his supplier and replace within a couple of hours. However, while examining the unit, he found that the evaporator coil was leaking. He recommended replacing it, and said he could come out in a couple of days to do that job. In the quote he provided, he included a free charge of freon to the system to get through the next couple of days as long as we used him to replace the coil. In the meantime, I checked pricing from another HVAC company, and it was slightly less than Edgar's quote. Edgar showed up with an assistant on Thursday morning as promised and had the new coil in within about 3 hours. I was very pleased with the work and professionalism.”John W.

“Finally, after 4 years of dealing with incompetent air conditioner repairmen I have found a truly knowledgeable technician in Edgar Mejia, owner of Nu-Air Air Conditioning Repair.”George H.

“The owner, Edgar, repaired my a/c. He was very professional, knowledgeable and most of all very honest. I highly recommend using NU-Air for all of your heating/cooling needs!”Michael
-
“I was referred to Edgar by my sister over 7-8 years ago. At that time he was with a larger company and I began to request him and him only to come out and service my A/C. He recently branched out to begin his own business and I have stuck with him as a loyal repeat customer. He is always on time and easy to get a hold of. I appreciate his honesty more than anything. He is very thorough in his work, he won't just come in and look at one thing, he will survey the entire unit to make sure everything is working properly. I would highly recommend him!”Ronald
-
“He really took his time explaining all of its features and what to expect from him and his service team.”Elizabeth G.
