Claim This BusinessAbout Nardco Heating & Air Conditioning
Nardco Heating & Air Conditioning has served Anderson, Indiana, uninterrupted since 1961, making it one of the longest continuously operating HVAC contractors in Madison County. The business maintains a perfect 4.9-star rating compiled across 1,287 customer reviews, a volume that indicates sustained neighborhood trust rare among regional contractors. Both residential homeowners and commercial property managers rely on Nardco for heating system installations, air conditioner replacements, boiler repairs, and the full spectrum of heat pump technologies including geothermal loops and ductless mini-split configurations. The company operates around the clock every day of the week, reflecting a structural commitment to emergency availability that many smaller operators cannot sustain.
Beyond conventional heating and cooling equipment, Nardco extends its service footprint into integrated home infrastructure. The business handles complete plumbing scope including tank and tankless water heater installations, whole-home repiping projects, drain cleaning via hydro-jetting methods, backflow prevention certification, and slab leak detection. A financing program enables larger projects to proceed without upfront capital strain, while maintenance plans offer scheduled Filter changes, system inspections, and priority scheduling for enrolled customers. Generator installation and air quality remediation products round out offerings typically requiring contractor-level certification.
Review narratives consistently identify individual technicians whose approach transformed potentially stressful service calls into resolved problems. Technician Zach earned recognition for diagnostic thoroughness paired with conversational manner that made homeowners feel assisted by a neighbor rather than sold a solution. Reviewer Keri described technician Ryan arriving with advance notification, photographing the faulty component to visually demonstrate the malfunction, and independently verifying warranty status rather than immediately recommending replacement. Another review named technicians Dave, Blake, and Gavin completing a water heater installation alongside a water softener hookup while explaining system operation to the homeowner throughout the process.
