Glendale Heights, Illinois

Glendale Heights was a small farming area served by the Glen Ellyn post office up until the 1950s, with a population of just 104 in 1959. Midland Enterprises ran by Charles and Harold Reskin started building houses in Glendale Heights in 1958. The Reskins bought two farms on Glen Ellyn Road north of North Avenue. Houses were first built on Glen Ellyn Road and Larry Lane near Fullerton Avenue. On June 16, 1959, a petition was filed and on July 13, the village became incorporated. The first election was held later on that summer on August 2.

The town was originally named Glendale as it was between Glen Ellyn and Bloomingdale, but after a conflict arose with the small town of Glendale in Southern Illinois, the city decided in March 1960 to add the term Heights, in reference to its different topographies, a difference of about 100 feet because of its location straddling the Valparaiso Morraine, thus becoming Glendale Heights.

Glendale Heights is located at 41°55'13?N 88°4'44?W? / ?41.92028°N 88.07889°W? / 41.92028; -88.07889 (41.920228, -88.078918).

According to the 2010 census, Glendale Heights has a total area of 5.51 square miles (14.27 km2), of which 5.37 square miles (13.91 km2) (or 97.46%) is land and 0.14 square miles (0.36 km2) (or 2.54%) is water.

Disappointing Service
It is not in my nature to judge people. Keeping focus on sales presentation only; No other product was presented other than replacing my current Trane equipment with the same make and model. I asked about the different SEER and AFCU products offered by Trane and others like Carrier, Lennox etc., and was told they are just more expensive and a waste of money. I was not presented with any product brochures for Trane or any other products. Just a written quote for basically what I currently have. You only get one opportunity to make a good first impression.
