L.L.D. Heating & Cooling is a local, family-operated HVAC company serving Waukegan, Illinois and nearby communities. We started with a simple goal: Make heating and cooling services more honest and accessible for the people around us.

Founder Heraclio Galvan saw firsthand how many homeowners were either overcharged or left without reliable service during extreme weather. Instead of building a large, impersonal company, he chose a different approach—keeping the business hands-on and local.

With a background in restaurant operations and commercial refrigeration, he gained real experience working with systems where temperature matters every day. After earning his HVAC/R license, he built L.L.D. Heating & Cooling to provide straightforward, dependable service without the runaround.

When you call us, you’re not speaking to a call center—you’re speaking directly with the person who will be doing the work. That means clear communication, honest pricing, and accountability from start to finish.

We take pride in helping our community stay comfortable, without making the process complicated or stressful.
