An HVAC company in Hammond, LA is only as good as its word — and Nick's has kept its word since 1981. What started as one technician with a trade-school education and a commitment to honest work is now Southeast Louisiana's most trusted name in heating and air conditioning, more than four decades later.
In 1981, after gaining hands-on experience with a local company and completing trade school, Nick founded his own business — Nick's Heating & Air Conditioning. The goal was simple: treat every customer honestly and do the job right the first time.
More than four decades later, that same standard still runs the shop. Today we install, repair, and maintain every type of HVAC system for homes and businesses across Southeast Louisiana — as a Carrier Factory Authorized Dealer with NATE-certified technicians on every job.
Four decades of trust doesn't happen by accident. These are the principles our team lives by on every Hammond service call.
We're honest and committed to doing what's best for the customer — even when that means recommending the cheaper fix.
Each of us is willing to do whatever it takes to move the company forward and take care of our neighbors.
We're always a phone call away. With a 24-hour answering service, we never miss a call — day or night.
We strive to do excellent work while giving every customer a great experience, start to finish.
We're constantly growing and continuing our education so you always get modern, efficient HVAC solutions.
To give our customers a comfortable environment, an excellent experience, and 100% customer satisfaction — every single time.
We back four decades of honest work with the certifications, memberships, and manufacturer partnerships that matter. When Nick's shows up, you're getting a fully credentialed team — not a fly-by-night operation.
