The AAA Pro HVAC Story

AAA Pro HVAC didn't start as a franchise rollout or a private-equity roll-up — it started with technicians who got tired of watching homeowners get overcharged for underexplained work.

Our Merrillville, IN fleet is stocked daily with the capacitors, contactors, ignitors, and control boards behind most common HVAC failures, so a single visit resolves most calls.

Ask a AAA Pro HVAC technician a technical question and you'll get a real answer, not a sales pivot — that's deliberate, and it's why customers stick around.

We carry general liability and workers' compensation coverage on every job in Merrillville, IN, which protects your property and our team equally.

We track every Merrillville, IN job through to a documented completion, which is part of why repeat calls on the same fault are rare. That same standard applies whether the call comes from a single-family home, a rental property, or a small business across Merrillville, IN.

Don't Ignore These Warning Signs

Catching a problem early, before it becomes a total breakdown, almost always means a shorter repair and a smaller bill.

Warm Air From the Vents

A system that runs but never actually cools usually means a refrigerant charge issue, a failing capacitor, or restricted airflow — not something a thermostat adjustment will fix. Ignoring warm air from the vents rarely makes the underlying issue cheaper to fix later.

Furnace Won't Ignite or Keeps Shutting Off

A furnace that clicks but never lights, or one that lights and shuts off within seconds, usually points to a failing ignitor, a fouled flame sensor, or a safety switch doing exactly its job. Our Merrillville, IN techs see this specific pattern often enough to diagnose it quickly rather than guess.

Rising Utility Bills With No Usage Change

Dirty coils, duct leaks, and failing components all show up on the utility bill before they show up as a total breakdown. Our Merrillville, IN techs see this specific pattern often enough to diagnose it quickly rather than guess.

Strange Noises: Grinding, Squealing, Banging

None of these noises are 'normal system sounds' worth ignoring — they're early warnings. Ignoring strange noises: grinding, squealing, banging rarely makes the underlying issue cheaper to fix later.

Uneven Temperatures Room to Room

This is one of the most misdiagnosed HVAC complaints, since it's tempting to blame the thermostat instead of the actual airflow path. Our Merrillville, IN techs see this specific pattern often enough to diagnose it quickly rather than guess.

System Short-Cycling

Short cycling is often caused by a dirty air filter, low refrigerant, or an oversized system, and it gets more expensive to ignore, not less. Ignoring system short-cycling rarely makes the underlying issue cheaper to fix later.

Emergency Hvac Repair Done Right, Every Time

Every job starts with a real diagnosis, not a guess — here's the full scope of what our Merrillville, IN technicians handle.

AC Repair & Installation

From a condenser that won't start to a full central air replacement, our Merrillville, IN AC technicians handle refrigerant leaks, compressor diagnostics, capacitor failures, and complete system installs. Refrigerant leak detection uses electronic detectors and UV dye, not a repeated top-off that never addresses the actual leak. This is one of the most requested Emergency Hvac Repair calls we get across Merrillville, IN.

Heating & Furnace Services

Every furnace call starts with a combustion analysis and carbon monoxide safety check before any repair recommendation, because a cracked heat exchanger is a safety issue first and a repair line item second. We carry ignitors, gas valves, and control boards for the major furnace brands installed across Merrillville, IN. This is one of the most requested Emergency Hvac Repair calls we get across Merrillville, IN.

Ductwork & Indoor Air Quality

Leaky, disconnected, or undersized ductwork can waste a significant share of a system's output before it ever reaches a vent — we test static pressure and duct leakage rather than sealing blind. Mastic sealing, not just tape, on any duct joint we repair, since tape degrades in attic heat within a couple of seasons. Techs handling ductwork & indoor air quality carry the specific parts and tools this job calls for, not a generic kit.

Emergency HVAC Service

Total no-heat and no-cool failures get priority dispatch across Merrillville, IN, day or night, holiday or not. After-hours pricing is disclosed on the call, before dispatch, so there's no surprise on the invoice. This is one of the most requested Emergency Hvac Repair calls we get across Merrillville, IN.

Preventive Maintenance Plans

Twice-yearly tune-ups, once ahead of cooling season and once ahead of heating season, catch the small issues that turn into mid-season breakdowns if left alone. Filter selection is matched to your specific system rather than a generic one-size recommendation. Techs handling preventive maintenance plans carry the specific parts and tools this job calls for, not a generic kit.

Commercial HVAC Service

Rooftop packaged units, commercial refrigeration-adjacent systems, and multi-zone office buildings across Merrillville, IN fall within our commercial service scope. Preventive maintenance agreements for Merrillville, IN property managers and facility teams keep equipment running and budgets predictable. Techs handling commercial hvac service carry the specific parts and tools this job calls for, not a generic kit.
