About Us
We Are L.L.D Heating & Cooling
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.

STONE WORK
Stone and brick have been used to construct structures for centuries. The Egyptians and Roman Empire used them to create palaces, houses, and walls and made bricks from clay and mud. Bricks continue to be made in an identical fashion. Clay and rocks are condensed into cubes and baked. The heat causes their chemical makeup to change, and the results are solid construction blocks.
Brick WORK
If built properly, a structure created from stone or brick is amazingly durable and can serve you for a lifetime. It exudes quality and craftsmanship due to the quantity of skill and time required to construct the dwelling. At HSD Masonry Modesto, CA, we're dedicated to providing California residents with stunning brick mailboxes, outdoor kitchens, and elegant entrance ways.
