Gnoth and Lukowski Heating and Air Conditioning

Gnoth and Lukowski Heating and Air Conditioning has served Mishawaka homeowners since its founding, delivering furnace and air conditioning installation, repair, and maintenance throughout the greater St. Joseph County region. The company holds proper licensing for residential HVAC work in Indiana, and maintains an A rating from the Better Business Bureau alongside its 4.5-star average across 32 verified client reviews. Owner Scott Lukowski remains directly involved in service calls, distinguishing this independently operated contractor from larger companies where homeowners often interact only with dispatchers. The business serves Mishawaka, as well as neighboring communities including Granger, Penn, and Nappanee, providing both scheduled maintenance and emergency calls throughout northern Indiana.

What separates Gnoth and Lukowski from neighboring contractors is the owner-operator model combined with straightforward pricing. Unlike larger firms that rely on commissioned sales teams, Scott Lukowski provides consultations himself and has repeatedly been praised for not recommending unnecessary work. Several reviewers specifically mention receiving a free thermostat after furnace installation, and multiple clients note the absence of surprise charges on final bills. The company maintains 24-hour availability, a practical necessity for Mishawaka homeowners facing sudden heating failure during regional cold snaps or AC collapse during summer heat waves.

Customer stories from verified reviews paint a clear picture of day-to-day operations. Grecia R. described Scott arriving promptly to diagnose an issue and providing a new furnace installation at a competitive price, declining to upsell unnecessary components. Amanda Pletcher reported calling at 7:09 a.m., receiving a callback within minutes, and having her non-functioning AC restored the same afternoon during one of the hottest days of the year. Another reviewer noted Scott Lukowski personally handling a 50-gallon water heater installation with friendly crews and transparent pricing, emphasizing no unexpected fees appeared on the final invoice.
