No reviews available

Lockwood Furnace Co. has been servicing the greater Chicago area for over 80 years, even before whole house air conditioners and air purifiers were a thought in people's minds.

The experts at Lockwood Furnace Co. are Trane Comfort Specialists and the trained staff will help make any equipment run efficiently so the customer gets maximum value. In addition to repairing air conditioners, they also install them so the customer can stay cool in the hot Chicago weather. Maintenance is recommended to keep the systems running smoothly and to prevent any problems down the line.

With decades in business, Lockwood Furnace Co. is able to diagnose and quickly fix any problems that arise. They keep their trucks fully stocked, so if a part is needed, they don’t need to go back the warehouse in order to fix the system. They provide 24-hour emergency service, especially in the winter months, where heating is absolutely crucial.

Boiler repair is the specialty of Lockwood Furnace Co. and their company was founded on fixing boilers. They have repaired every type of boiler in both residential and commercial settings, and will go over the problem with customers so the customer knows what is being fixed, how much it costs and why the problem happened in the first place. They offer maintenance checks on any equipment to ensure it’s working optimally and to catch any need for necessary repairs.

In addition to repairs, Lockwood Furnace Co. provides customers with new HVAC systems, whole house humidifiers, boilers, air purification systems and ductless HVAC options.

Lockwood Furnace Co. is located in Joliet and serves a number of communities in Illinois, including Lockport, Naperville, Shorewood and more.
