We have answered the HVAC Needsof Naperville, Illinois for More than 80 Years

Since 1932, Lockwood Furnace has served the HVAC needs of Naperville. Naperville’s history is interesting to us; our company was founded almost 100 years exactly after Naperville. We were replacing and servicing boilers and furnaces in Naperville before the word HVAC had even been invented! The air conditioner came several years after we were founded as well. We have grown with the heating and cooling industry, but we have never forgotten our roots. We were, and remain, a family business that is part of the Naperville community.

Throughout Naperville, Lockwood Furnace has serviced, repaired and installed central heating and air conditioners, furnaces, boilers, whole house humidifiers, high velocity and air purifying products. There isn’t a home, business or industrial HVAC challenge in Naperville that our professional technicians haven’t seen. We can service, repair or even retrofit virtually any HVAC system made.

Lockwood Furnace offers Naperville 24 hour emergency HVAC service for any heating or cooling problem. We understand that a furnace shutdown in winter represents an emergency. We also have excellent maintenance and servicing programs to keep any air conditioner, furnace, boiler or other piece of HVAC equipment in top shape the entire year around.
