Growing North of Lafayette
Carencro has experienced steady residential growth, particularly along the I-49 corridor and the areas branching off Hector Connoly Road and Gloria Switch Road. New subdivisions continue to fill in the gaps between Carencro and Lafayette, and custom homes are going up on acreage along the edges of town toward Scott and Sunset.
Every new home needs an HVAC system. The question is whether that system gets designed for your specific house or selected off a generic chart. F & R Air Conditioning designs new construction HVAC systems using engineering calculations, not shortcuts.
From Blueprint to First Cool Day
Step One: Review Your Plans
We start by reviewing your architectural drawings or builder’s plans. Before we calculate anything, we need to understand the layout, room usage, window placement, insulation specifications, and ceiling heights. A vaulted great room with a wall of west-facing windows has a completely different cooling demand than a standard 8-foot bedroom on the east side of the house.
Step Two: Run the Numbers
Manual J load calculations determine the exact heating and cooling capacity your home needs. This calculation accounts for everything from insulation R-values to the number of people who’ll be living in the house. Oversizing is one of the most common mistakes in new construction HVAC. An oversized system cools the air quickly but shuts off before it’s had time to remove moisture, leaving your home cold and clammy. In Louisiana’s humidity, correct sizing is critical.
Step Three: Design the Distribution
Manual D duct design maps out every supply run, return path, and trunk line. We design for balanced airflow so rooms at the end of long duct runs aren’t starved while rooms near the air handler get blasted. Your builder needs this information before framing is complete so mechanical chases and soffits can be built into the structure.
Choosing Equipment for the Long Run
New construction gives you the widest range of equipment choices. You’re not limited by existing ductwork size, electrical panel capacity, or outdoor unit pad locations. This is the time to consider variable-speed systems that adjust output to match your home’s real-time needs, operating at partial capacity most of the day rather than cycling between full blast and off.
Variable-speed equipment costs more upfront but delivers measurably better comfort and lower monthly bills. Over a 15-year equipment lifespan, the operating cost difference is significant, especially given how many months per year we run cooling in Acadiana.
Fresh Air and Moisture Management
Modern building practices create tighter homes, which is the point: you don’t want conditioned air leaking out through the walls. But a tight house needs controlled ventilation. We incorporate mechanical ventilation (typically an ERV) into new construction designs to bring in fresh air without dumping raw Louisiana humidity into your conditioned space.
For homeowners who want extra moisture protection, we can integrate a whole-home dehumidifier into the system design from the beginning, which is far easier and cheaper to do during construction than retrofitting later.
