Mr Freeze HVAC | Certified HVAC Repair in Chicago, IL

This is a very common issue in our older Chicago neighborhoods, often caused by air duct leakage in attics, basements, or crawlspaces. Leaky ducts force your furnace to work much harder, pushing warm air into unused spaces instead of your living areas. Mr Freeze HVAC performs thorough duct inspections and sealing to immediately improve comfort and reduce those high winter energy bills.

Furnace ignition failure is a frequent winter emergency call for us. The culprit is often a dirty flame sensor, a faulty igniter, or issues with the gas valve or pressure—all exacerbated by Chicago's cold, damp conditions. Our technicians are trained to safely diagnose and repair these ignition system components quickly, restoring heat to your home and preventing future failures.

A professional pre-winter furnace tune-up is crucial. Our comprehensive service includes cleaning critical components like the flame sensor and burners, checking gas pressure and the ignition system, and inspecting for duct leaks. This proactive visit from Mr Freeze HVAC can prevent the majority of no-heat emergencies, ensure efficient operation, and give you peace of mind all season long.
