Heating & Air Conditioning Repair & Service - Joliet & Southwest Suburbs

Welcome to Lockwood Furnace CompanySince 1932 – The Southwest & West Suburban Heating & Air Conditioning Company

Lockwood Furnace is a family business that has been servicing the HVAC needs of Greater Chicago since 1932. You might say we have grown up with central air conditioning and heating. In fact, when we were first established, air conditioners were still a dream.

We are proud to say that over the years, Lockwood Furnace has serviced, repaired and installed virtually every air conditioner, furnace and boiler made; residential or commercial, from Joliet, Illinois to Essex to Yorkville and back again. HVAC is in our blood, and in fact, when we were established, no one even called it HVAC!

Our heating and cooling technicians are highly trained technically, but just as important, they are pretty special people. You see, we have earned our reputation not by spending a lot of money on slick advertising or radio commercials, but by word of mouth. While we are up-to-date on every piece of HVAC information available, we are downright old fashioned when it comes to customer service, respect and treating your situation as if it was our own.

The Greater Chicago HVAC Company You Can Trust

At Lockwood Furnace, we know that everything comes down to trust. When we are servicing your central air conditioner in Naperville, repairing a whole house humidifier in Coal City or replacing a Trane furnace in Elwood, homeowners and businesses have come to know we will do what is best for you.

While Lockwood has won countless awards for HVAC excellence from Trane and from numerous publications such as Chicago magazine, what matters most to us is your satisfaction as our customer.

After all is said and done, Lockwood Furnace is a family business here in Greater Chicago and we have a reputation based on solid values and our commitments to everyone we serve. This is why we have succeeded since 1932 and why we will continue to serve in the years ahead.
