OK Heating & Air Conditioning, Inc. has been in business since 1986.  We are locally owned by Dave Kaltenberg and enjoy serving Verona and the surrounding communities.  We take great pride in the work we do and our technicians continually attend training classes and seminars to keep up with the latest technology in the industry.

We are small enough to offer personalized care and big enough to offer a full service of professional products.  See our "Products" page to get links to our full product line.


We also offer the Comfort Care Program, which is a program that provides annual maintenance for all your HVAC equipment, an important service for worry-free, efficient operation.  See our "Services" page for a complete description of our Comfort Care Program.
