AA Service Co

What AA Service Co does

AA Service Co. is a family-owned, private home services company founded in 1965 and headquartered in Northbrook, Illinois. It provides installation, maintenance, and repair of residential and light-commercial HVAC (heating, cooling, geothermal, high-velocity, ductless mini-splits, boilers, furnaces, heat pumps, radiant flooring, snow melt), plumbing (water heaters, gas lines, sump pumps, filtration, repiping), sewer and drain (hydro jetting, trenchless sewer), electrical (lighting, EV chargers, generators, surge protection, safety inspections), and indoor air quality systems to homeowners across the Greater Chicagoland and North Shore area.

The company operates as a direct-to-consumer, field-service model: technicians are dispatched from a single Northbrook hub to customer homes, with 24/7 emergency availability, same-day service windows, online scheduling, and a fleet of NATE-certified technicians. Technical differentiation is concentrated in specialized system categories rather than proprietary technology — the firm is an authorized dealer/installer for OEMs including Lennox, WaterFurnace, Rheem, NTI, Mitsubishi (DC Elite), and Unico (Preferred Contractor), and supports installation of Aprilaire, Honeywell, and Mitsubishi smart-thermostat and IAQ products.

Revenue is generated primarily through transactional professional services (diagnostics, repair, installation) billed per visit or per project, supplemented by recurring maintenance/membership plans (priority scheduling, 10% off labor and materials, no-breakdown guarantees) and the company's own promotional incentives (e.g., $99 diagnostics, $109 tune-ups, $2,000 boiler replacement rebates, up to $4,225 in combined rebates on complete HVAC replacements). Utility rebate partnerships (ComEd, People's/Nicor Gas) effectively lower the customer-acquisition cost for premium replacements. The commercial vertical (HVAC and restaurant jetting) is a secondary revenue stream.
