Lockwood Furnace CompanyMeeting all the Heating and Cooling Needs of Frankfort, Illinois

We found it interesting that Frankfort was first settled in 1831, about a century before our family thought about establishing Lockwood Furnace! Our family started the company in 1932; while we’re not as old as Frankfort, 80 plus years in business is a long time for any company. We were replacing and servicing heating systems before anyone even dreamed up “HVAC.” We have grown up right along-side the heating and cooling industry, but we have never forgotten where we came from. We remain a family business (now in the third generation) and we feel a part of the Frankfort community.

Lockwood Furnace services, repairs and installs central HVAC systems, along with furnaces, boilers, whole house humidifiers, mini-duct systems and air purification products throughout Frankfort. In fact, there isn’t a home or business HVAC challenge in Frankfort that our professional technicians haven’t seen. We can service, repair or even retrofit virtually any heating and ac system made.

Lockwood Furnace offers 24 hour emergency service of course, throughout Frankfort whether winter or summer, as well as industry leading maintenance and servicing programs to keep any air conditioner, furnace, boiler or other piece of HVAC equipment in the best condition.
