Replacing Your AC in Duson
Duson may be small, but your cooling needs are the same as any home in Lafayette Parish. Summer heat, Gulf Coast humidity, and a cooling season that runs most of the year put serious demands on your air conditioner. When that system reaches the end of its lifespan, finding the right replacement matters.
F & R Air Conditioning has been serving Duson and the surrounding communities since 1956. We’re not a big-city franchise dispatching from hours away. Our Abbeville base puts us close enough to provide responsive service while bringing decades of regional expertise.
Why a Load Calculation Matters
It would be easy (and fast) to look at your home’s square footage and slap a number on it. But that approach leads to incorrectly sized systems, and in South Louisiana’s humidity, incorrect sizing is expensive.
We perform Manual J load calculations on every installation. This evaluates your home’s insulation, window area, ceiling height, sun exposure, ductwork, and building tightness. All of these factors affect how much cooling your home actually needs.
Two common problems result from skipping this step:
Oversizing: the system blasts cold air, hits the thermostat setting quickly, and shuts off. The evaporator coil doesn’t have time to condense enough moisture from the air. Your home gets cold but stays humid. The frequent starts and stops also shorten compressor life.
Undersizing: the system runs nearly non-stop during peak summer, never reaches your desired temperature, and your electric bill reflects the constant operation.
The load calculation finds the correct capacity, and that’s what we install.
Equipment That Handles the Climate
SEER2 Efficiency
If your current system is a decade or more old, it probably operates at 10 to 13 SEER. The current minimum is 14.3 SEER2, so even a basic replacement can cut cooling energy use by up to 30%. For Duson’s 8-month cooling season, higher-efficiency models (17-20 SEER2) save more over the system’s lifetime, though equipment costs increase with each tier.
We present projected savings based on your home’s calculated load so you can see the real-dollar impact of each option.
Handling Humidity
This is the factor that separates good equipment choices from mediocre ones in our climate. Two-stage compressors spend most of their operating time at reduced speed, which means longer run cycles and better moisture removal from the air. The indoor environment feels drier and more comfortable compared to a single-stage system at the same thermostat setting.
Variable-speed compressors take this concept further, adjusting output continuously based on demand. They’re the most efficient, quietest, and best at humidity control, though they carry a higher price tag.
For most Duson homes, a two-stage system hits the right balance of performance, comfort, and cost. Variable-speed is the upgrade for homeowners who want peak performance.
