New Iberia Heating Installations
New Iberia is the largest city in Iberia Parish, and its residential neighborhoods span a range of construction eras and styles. The historic districts along Main Street and East St. Peter Street include homes that are over a century old, some with original steam radiators that were converted to forced-air decades ago. Drive out toward the Loreauville Road or Jane Street corridors and you’ll find mid-century homes with ductwork that’s seen better days. The newer developments along Highway 90 and the Jefferson Island Road side of town tend to have modern heat pump systems that are approaching their 15-to-20-year replacement window.
Each of these situations calls for a different approach to heating installation. We’ve been working in New Iberia long enough to know the common problems in each part of town, and we factor that local knowledge into every recommendation.
The Gas vs. Heat Pump Question
For New Iberia homeowners, the decision between a gas furnace and a heat pump often comes down to what’s already in the house.
If your home has a gas furnace with an existing gas line and proper venting, replacing it with a new high-efficiency gas furnace is usually the simplest and most affordable path. Modern gas furnaces with 95% or higher AFUE ratings waste almost nothing, they burn cleaner, and they produce warm air at the registers within seconds of startup. For the older homes in the Duperier Avenue and Corinne Street neighborhoods, where insulation is thin and windows may be single-pane, that quick blast of warm air makes a noticeable comfort difference.
If your home currently runs a heat pump (or a straight AC system with electric heat strips), staying with a heat pump makes sense. Today’s heat pumps are dramatically more efficient than the units installed even 10 years ago. Variable-speed compressors adjust output to match the actual heating load, so instead of cycling on and off, the system runs continuously at a lower speed. That means steadier temperatures, better humidity control (even in winter, Iberia Parish humidity can be a factor), and lower utility bills.
Sizing for Iberia Parish Conditions
Proper sizing is the single most important factor in a heating installation, and it’s where a lot of installations go wrong. The Gulf Coast climate creates a specific challenge: your heating system also needs to cool your home for seven or eight months of the year. If the system is oversized for heating, it will short-cycle during cooling season and fail to remove humidity effectively. If it’s undersized for heating, you’ll be cold on the few genuinely chilly nights we get.
We run a Manual J load calculation that factors in your home’s insulation, window count and type, orientation, ceiling height, and ductwork condition. This gives us the exact heating and cooling capacity your home needs, not a rough guess based on square footage.
Ductwork: The Hidden Variable
In many New Iberia homes, especially those built between the 1960s and 1990s, ductwork runs through unconditioned attic space. Over two or three decades of Louisiana heat and humidity, duct connections loosen, insulation compresses, and seams develop leaks. A home with 25% duct leakage is losing a quarter of its heated air before it ever reaches a register.
We evaluate ductwork condition as part of every heating installation. If your ducts need repair or replacement, we’ll recommend handling that at the same time as the equipment installation. The labor efficiency of doing both together usually saves money compared to addressing them separately.
Installation Process
A standard heating system replacement in New Iberia takes one day. We remove the old equipment, install the new furnace or heat pump, complete all gas, electrical, and refrigerant connections, and test the entire system before leaving. Conversions from gas to heat pump (or vice versa) take a day and a half to allow for the additional wiring and configuration work.
As a Lennox® Premier Dealer, we install high-efficiency Lennox furnaces and heat pumps backed by strong warranty coverage. We also work with other major brands if you have a preference.
