Whether it's a furnace that won't kick on or a walk-in cooler acting up, Mr. Lou and the team show up ready to help.
Furnaces, heat pumps, boilers — we diagnose fast and get your warmth back before the next cold snap hits.
Central AC install, repair, and seasonal tune-ups. Stay cool through every Illinois summer without skipping a beat.

Regular tune-ups catch small problems before they become big headaches — and they save you money on energy bills too.

From single-family homes to restaurant kitchens, we size the solution to the space — no job too big or too small.
Mr. Lou's Heating, Cooling & Refrigeration is rooted right here in Sandwich, Illinois. We know this community because we live in it — and that's exactly why we do what we do.
When you call us, you're not talking to a call center halfway across the country. You're talking to real people who show up on time, explain what's going on in plain English, and charge a fair price — every single time.
Whether it's a quick repair or a full system replacement, we treat your home the way we'd want ours treated. That's the Mr. Lou promise.
Call us and a real human picks up. No IVR maze, no hold music for twenty minutes — just someone ready to help.
We tell you the cost before we start the work. No surprises on the bill, no "while we're here" upsells you didn't ask for.
When we're done, your space looks as good as it did before we arrived. We respect your home like it's our own.
We know Sandwich, we know the buildings, and we know the weather patterns that wear on your systems. That experience matters.
Based at 31 East Church Street, we cover Sandwich and nearby areas throughout DeKalb County and beyond. When you need us, we're close by.
Give us a call, send an email, or swing by the shop — however you reach us, we'll get back to you fast.
