Gill's and Carrier


Gill's proudly installs Carrier HVAC equipment.

Gill's Refrigeration Heating and Air Conditioning in Chillicothe IL has been providing the greater Chillicothe area with quality Carrier heating and cooling equipment installations since about 1991.  Lets face it modern heating and cooling systems are far more advanced than their predecessors. Buying a well made and designed HVAC system is more important than ever before. And just as important is the install, you want it done right.  

Antique refrigeration


Old doesn't always mean not usefull.

In many cases it is still possible to repair antique refrigeration equipment. When time allows antique refrigeration restoration work is sometimes done by Gill's Refrigeration Heating and Air Conditioning in Chillicothe Il. I have a rather extensive knowledge of antique refrigeration equipment such as this early 1930's Coldspot refrigerator.  If you have a family heirloom or prized man cave refrigerator in need of repair and you want to save it it a diagnostics call will tell you if it is possible.
