With the ability to dispatch from Cary and Marengo, Air-tech has been providing service in McHenry County since 1988. It is quite likely that we have installed systems or performed service for one of your neighbors. We pride ourselves in providing expert, courteous, personalized service, which has led to many long-term client relationships. We feel it is important to not only install a system that is appropriate and economical, but also provide any preventative maintenance programs to keep our clients satisfied with the work we do and the systems we install. This is why we would be happy to provide referrals for our work, and very likely from someone in your neighborhood.
