Discover the possibilities of Inverter air conditioning

We asked Kornél to clean three indoor units and one outdoor unit. He was able to tackle the task with time and energy. We were impressed by his precision and expertise and asked him to continue working with us. I can only recommend him!

I can sincerely recommend KoósAir Technic, because it is backed by a person whose personality guarantees that you will not be fooled and that your climate will be fine. Planning an air conditioning system for 2022 is worth starting in 2021!

Extremely polite, punctual, helpful, and patient professional. I can only recommend him.

I can recommend the contractor from my own experience, because he is reliable, honest, and does a precise and conscientious job. And the fact that it is easy to make an appointment with him is a great advantage..

I contacted Kornél through a recommendation for an air conditioning problem that was previously installed by another company. Unfortunately, I was unable to use the air conditioner last summer as it had stopped cooling, and unfortunately the other company who had installed it had provided a quick but inefficient solution, which resulted in the system stopping cooling again after a few weeks. I asked Kornel to fix the problem, as I was disappointed to have been let down by the other company, and I didn't want to go into the summer not being able to use my air conditioner again. I got an appointment quickly, it arrived on time. He was accurate, careful, thorough and very attentive to the cleanliness of the apartment. He showed up very prepared, with lots of high quality tools and meters, which helped us find the source of the problem. He investigated for a long time and did a very conscientious job. I received a written professional opinion on the same day, which enabled me to get the other company to carry out the work and correct the errors they had made. I thank him and can only recommend him! He will not let you down!

We met Kornél Koós as a very correct and trustworthy specialist. He responded very quickly to our request, and sent us a precise, accurate quote within 1 day after the visit. We didn't have to wait long for the execution, we agreed on the installation time in a flexible way. The maintenance of the old air conditioning equipment was carried out in an incredibly careful and professional way, with special attention to the care of the office equipment, which was very impressive for me. I can only recommend his service and work to everyone.

They managed to install 2 split air conditioners in 2 separate locations in one day. They were kind, polite, fast and very flexible. We are very happy with everything and would definitely recommend KoósAir-Technic.

Thank you for your professional, accurate and clean work. I am completely happy with the type of the air conditioner recommended, it has performed well in the heat of the last few days. What I would also like to point out is that you undertook the air conditioning installation more than 160 km from your location. He arranged the on-site survey via online video call and then arrived with a complete service van, which provided the full tooling requirements for the installation. I can only recommend him..

Before the birth of our baby, we wanted to make sure the air conditioning was completely cleaned. Unfortunately, we have found that if you choose the wrong specialist, they are willing to say the job is done even if the deep cleaning has not been done. After the initial disappointment, we were lucky to have found KoósAir-Technic, who did a precise, accurate and careful job of cleaning our air conditioning. I can safely say that from now on KoósAir-Technic will take care of the regular cleaning of our air conditioner, and I would recommend them to everyone.

I contacted KoósAir-Technic for annual pre-season air conditioning maintenance, recommended by a friend. They were flexible when making the appointment and took my other activities into maximum consideration. The air conditioner was properly cleaned and sterilized without any mess in the apartment. They worked cleanly and carefully. Work done correctly, at a fair price. I will call them again, I can only recommend them.

They worked quickly, expertly, accurately and cleanly. As we live in an attic, we needed the equipment very much. The air conditioner is quiet, but still cools very well. The whole family enjoyed the well cooled apartment in the summer. The team of KoósAir-Technic is really professional, I can only recommend them to everyone!

I met Kornél in a business community, and because of his charisma and professionalism, I immediately saved his phone number as a recommendable partner in the field of air conditioning. At the time I didn't think we would need him, but of course one thing is constant and that is constant change. When it came up in my family as well, I knew immediately that I would call him and I am extremely grateful for the technical humility, helpfulness and professionalism with which KoósAir-Technic took the whole task off our shoulders and our south-facing rooms are now prepared for winter heating and summer cooling as well. They were quick, excellent and dust-free in all their work, answering all questions accurately, precisely and most importantly, clearly. For my part, I can safely recommend working with this company and wish them every success in the future!

Everything was perfect. You work professional and clean. I am 100% satisfied. And you have polite manners. Thank you again!
