About Delaware, Ohio

The small college town of Delaware, Ohio has been the county seat of Delaware County for nearly 200 years. It is the birthplace of the 19th president of The United States, Rutherford B. Hayes, and home of the Little Brown Jug and Ohio Wesleyan University. While the city and county of Delaware are named for the Delaware Indian tribe, the city of Delaware itself was founded on a Mingo village called Pluggy’s Town.

Why did we open this Delaware Ohio office?

With the growth of Custom Air in both commercial and residential in Marion, Morrow, Union, Knox and Delaware counties, we felt having a satellite business would be more efficient and get us more involved in the local communities.  We also found that 25% of our work force live in these counties.

Many times in rural communities the services delivered are not always by licensed contractors.  This brings folks to your business or home with no insurance and many times lack of skills to do the job the right way.  At Custom Air we deliver all of this, every time.

Selected Custom Air Projects

Delaware OH basement requires horizontal Tempstar Furnace

An 1880s home in Delaware County had a 35-year-old low-boy furnace on the floor in the short basement. It was a big job, but our talented installers made sure it was done neatly.  It looks and works great and will save energy.  A future project may include a Mitsubishi Zoned Comfort System to serve the second floor, to manage the summertime cooling requirements.
