Zero Degree Heating & Cooling: Experienced HVAC Services Serving Chicago, IL 60631

Our process uses specialized equipment to thoroughly remove dust, debris, and allergens from your entire duct system. Following cleaning, we offer an optional sanitization treatment to address microbial growth, which is common in Chicago's humid summers. This service helps improve indoor air quality and can enhance your HVAC system's efficiency.

For aging Chicago AC units, a common issue is a refrigerant leak, which reduces cooling capacity and strains the compressor. Other signs include ice on the coils or unusual hissing sounds. We recommend scheduling a professional diagnostic. Our technicians can pinpoint leaks, assess repair viability, and discuss replacement options if your system is inefficient or uses outdated refrigerant (like R-22).

Chicago's extreme temperature swings put significant stress on heating and cooling systems. Our maintenance service includes inspecting, cleaning, and tuning all critical components. This proactive care helps prevent mid-winter furnace failures or summer AC breakdowns, improves energy efficiency to manage utility costs, and extends the overall lifespan of your equipment.
