Indiana summers don’t mess around. When July hits, and temps push into the 90s with humidity to match, your air conditioning isn’t a luxury — it’s a necessity. All American HVAC is a full-service air conditioning contractor serving Crown Point and all of Northwest Indiana. From installing a new system to repairing your existing unit to keeping it running efficiently year after year, we handle all of it.
When your AC stops cooling or starts making concerning noises, we get a technician out fast. We repair all major brands and all system types — central air, heat pumps, ductless mini-splits, and rooftop units.
Common repairs we handle:
We stock the most commonly needed parts on our trucks, so most repairs are completed in one visit.
Whether you’re replacing a worn-out unit or installing air conditioning in a home that’s never had it, we’ll make sure the job is done right. Every installation starts with a load calculation — not a guess. We factor in your home’s square footage, insulation, window exposure, number of floors, and more. The result is a system that’s properly sized to cool your home efficiently without short cycling or running nonstop.
We install central AC systems, heat pumps, and ductless mini-splits. We carry equipment from multiple manufacturers, and we’ll recommend the one that fits your situation best — not just whatever has the highest margin.
An annual AC tune-up in the spring is the best insurance policy against a breakdown on the hottest day of summer. Our maintenance visits include coil cleaning, refrigerant level checks, electrical connection tightening, thermostat calibration, condensate drain clearing, and a full performance test. Homeowners who maintain their systems annually see fewer breakdowns, lower energy bills, and longer equipment lifespans.
Beyond standard repair, maintenance, and installation, we offer several specialized air conditioning services:
Each of these services has a dedicated page on our site where you can learn more about what’s involved.
Crown Point’s summer humidity puts extra strain on air conditioning systems. High humidity levels force your AC to work harder to remove moisture from the air, not just cool it. Systems that aren’t properly maintained struggle with humidity control, leading to that clammy, uncomfortable feeling even when the thermostat says it’s cool enough. Regular maintenance keeps your system dehumidifying effectively.
