NU-Air Heating & Cooling, LLC

NU-Air Heating & Cooling, LLC has served Mandeville and the surrounding St. Tammany Parish communities since its founding by a veteran-owned operation with more than two decades of industry experience. The company holds proper licensing and insurance, providing both residential and commercial HVAC services across eight cities including Covington, Lacombe, Madisonville, Abita Springs, Slidell, and Lewisburg. With an exceptional 4.9-star rating drawn from 378 customer reviews, the company has established itself as one of the most trusted names in northshore heating and cooling.

What distinguishes NU-Air from other area contractors is their team of NATE and Trane Variable Speed certified technicians, which ensures every installation and repair meets manufacturer specifications. As an authorized Daikin dealer, they provide access to premium mini-split systems alongside traditional Goodman equipment for whole-home solutions. Their service menu goes beyond standard repairs to include duct replacement and repairs, air purification systems, and comprehensive maintenance plans designed to extend equipment life and improve indoor air quality.

Reviewers consistently name specific technicians who delivered exceptional service. Michel earned high praise for correctly diagnosing and rectifying another contractor's improper installation, including reversing an upside-down unit and replacing an undersized capacitor. Edgar and his team repaired both a Daikin mini-split and a Goodman whole-house system, with one reviewer noting their courteous, clean, and efficient approach. Another customer highlighted technician Pat's same-day Sunday arrival to replace a breaker, calling the company trustworthy enough to leave their house unlocked during maintenance calls.
