Heating Services in Palos Hills, IL — Including Mitsubishi intelli-HEAT Dual-Fuel Systems
Smarter Home Heating for Palos Hills, Orland Park, Lemont & the Southwest Suburbs
Illinois winters are no joke. When temperatures drop into the teens — or below zero — your home’s heating system has to perform without hesitation. At A-Guy Heating & Air, we provide the full range of heating services for Palos Hills and surrounding communities, from furnace repair to complete system replacements. But increasingly, the smartest choice for southwest suburban homeowners isn’t just a new furnace — it’s a Mitsubishi intelli-HEAT dual-fuel system.
intelli-HEAT pairs a high-efficiency Mitsubishi Electric heat pump with your existing gas furnace, creating a hybrid heating system that automatically uses the most economical fuel source at any given temperature. When outdoor temps are mild, the heat pump handles the load at a fraction of the cost of gas. When it gets truly cold, the furnace kicks in seamlessly. The result: lower energy bills and uninterrupted comfort all winter long.

Frequently Asked Questions
What is a dual-fuel heating system?
A dual-fuel or hybrid heating system pairs an electric heat pump with a gas furnace. The system uses whichever fuel source is more efficient at a given outdoor temperature — typically the heat pump down to around 30–35°F, then the gas furnace in more extreme cold. Mitsubishi’s intelli-HEAT takes this further, with H2i technology that allows the heat pump to operate efficiently even well below 0°F.
