Serving Wilmington, Illinoiswith the Best HVAC Technician

We love the small towns and villages in our area of coverage. Maybe it’s because Lockwood Furnace grew up here too. Lockwood Furnace is a third generation family business. We believe in small town values and in doing exceptional, quality work.

Lockwood Furnace has been around since 1932. In the world of heating and cooling that’s a pretty long time; in fact, more than 80 years. You don’t get to be in business this long without making a lot of customers happy; whether in Wilmington or a nearby community. We are very proud of how our customers rate our many services.

We were installing and servicing boilers and furnaces in Wilmington long before the word HVAC had even been invented! We will always work hard to find the best solution for any Wilmington HVAC problem. We understand that no heating or cooling problem is ever as important as your problem, and we always work solve it. We are proud of our honesty and ethical behavior. We have grown strong with the heating and cooling industry, but we have never ever forgotten our roots. We were, and remain, a family business that is part of the Wilmington community.

Lockwood Furnace has 24 Hour EMERGENCY SERVICE throughout Wilmington for any heating or cooling problem. You call us, and we will be there as fast as possible. We also routinely maintain and service all HVAC equipment on an appointment or plan basis to keep your home or business in top shape.

We Install Trane and Lennox throughout Wilmington

Lockwood Furnace is certified as a Trane Comfort Specialist. It is a very high rating and we take the level of training very seriously. We recommend and install the complete line of Trane and Lennox HVAC products throughout Wilmington. We have seen far too many of the so-called budget brands fail. They are energy wasters and highly inefficient! A good system will pay for its slightly higher price over time in energy savings. We only recommend systems we have seen in action over the many years we have been in business.

Nevertheless, the most efficient systems are only as good as the experts who install and maintain them. Our factory trained HVAC techs are exceptional people. We are proud of them!
