A new AC system is one of the most important investments you'll make in your home or business. Nick's Heating & Air Conditioning ensures it's sized right, installed right, and built to perform in Louisiana's demanding climate — backed by 40+ years of expertise and a Carrier Factory Authorized Dealer certification.
Whether you're replacing a failing system, upgrading to a more efficient unit, or installing AC in a new build, the quality of your installation determines how well your system performs for the next 15 years. A system that's improperly sized or hastily installed costs you in comfort and energy bills every single month.
Nick's takes the time to assess your space correctly, match you with the right system for Southeast Louisiana's climate, and install it with precision — the same approach we've used for over 40 years. As a Carrier Factory Authorized Dealer, we also bring factory-level training and warranty protection to every installation.
Brands We Install
Every property is different. We'll help you choose the right system type for your space, budget, and how you use it.
A central AC system uses your home's existing ductwork to cool every room evenly from a single unit. It's the most common system type in Southeast Louisiana, and a properly sized central system is the most cost-effective option for most homes and businesses.
Ductless mini-splits deliver cooling (and heating) directly to individual rooms without ductwork. They're the go-to solution for home additions, converted spaces, older homes without ducts, garages, and any area where running new ductwork isn't practical.
A heat pump is a single system that both cools your home in summer and heats it in winter by reversing its refrigerant cycle. In Southeast Louisiana's mild winters, heat pumps are extremely efficient — often eliminating the need for a separate furnace altogether.
A dual-fuel system pairs a heat pump with a gas furnace. The heat pump handles cooling in summer and efficient heating in mild weather, while the furnace takes over when temperatures drop below the heat pump's efficient operating range. Best of both worlds.

In Southeast Louisiana's extreme heat and humidity, the single most important thing about an AC installation is correct sizing. Most homeowners don't know this — but it can cost them thousands.
An oversized AC cools the air too fast and shuts off before removing humidity — leaving your home feeling clammy even at a low temperature. Short cycling also wears out the compressor years early. This is the most common installation mistake in our area.
An undersized system runs nonstop trying to keep up with the heat and never quite gets there. Your home stays warm, your energy bills stay high, and your system wears out from overwork long before it should.
A properly sized system runs full cooling cycles, removes humidity effectively, keeps your home comfortable, and operates at peak efficiency for its full expected lifespan. Nick's uses Manual J load calculations — the industry standard — to get this right every time.
Beware of "same size as the old one" installs. If a contractor proposes sizing your new system based solely on what was there before — without doing a load calculation — that's a red flag. The previous system may itself have been wrongly sized, and your home's insulation or layout may have changed.

AC sizing is determined by a Manual J load calculation — not just square footage. The right size depends on your home's square footage, ceiling height, insulation levels, window count and orientation, and local climate conditions. In Southeast Louisiana's extreme heat and humidity, oversizing is a common mistake that causes short cycling, indoor humidity problems, and premature equipment failure. Our technicians perform a proper load calculation before recommending any system.
A standard residential AC replacement is typically completed in a single day — usually 4 to 8 hours depending on system type and whether ductwork modifications are needed. New construction or ductless multi-zone installations may take longer. We'll give you a realistic timeline as part of your free estimate.

Yes. A modern, energy-efficient AC system is an attractive selling point for buyers in Southeast Louisiana's warm climate. High-SEER systems reduce monthly energy costs, which buyers factor into their decisions. The exact value added depends on the system type, local market conditions, and the age of the equipment being replaced.
A traditional AC system only cools. A heat pump can both cool in summer and heat in winter by reversing its refrigerant cycle — making it highly efficient for Southeast Louisiana's mild winters. In Hammond's climate, a heat pump often eliminates the need for a separate furnace, reducing your total equipment cost and energy use during the cooler months. Our technicians can walk you through both options during your free estimate.
Installation is the beginning of the relationship. Nick's also handles all your ongoing AC service needs — so your new system performs for its full lifespan.
