Why Lockwood Furnace CompanyHas Never Changed It's Name

Over the past 80 years, we must admit that from time to time, we have been tempted to change our name to something maybe a little fancier or more high tech or catchier. Harlow Lockwood, the third generation of Lockwood’s to own the company puts his foot down and says, “No!” every time the subject comes up.

You see, when we were founded, whole house air conditioners anywhere in Greater Chicago were only a dream, and whole house humidifiers or air cleaners, were not even science fiction! At the time, we only repaired, serviced and installed furnaces and boilers, because that is all we had. Over the years our HVAC technicians became experts in air conditioning, whole house humidifiers, air cleaners and air purifiers. Of course we install air conditioners, air cleaners and humidifiers. As a matter of fact we are authorized dealers of Trane and Lennox air conditioning. Our technicians are Trane Comfort Specialists and have received the finest training in the industry.

The name Lockwood Furnace has been Chicagoland’s most trusted name in home comfort since 1932. We have grown into a large company, but we will never forget our humble roots and what our grandfather stood for all those years ago. So when you need help with your heating or cooling system, we will always be here for you.
