Heating and Cooling Without the Complexity
Sunset is a close-knit community in St. Landry Parish, tucked between Opelousas and Carencro along Highway 93. Like most of Acadiana, you deal with summers that start early and hang around late, followed by winters that are more damp and chilly than truly cold. A heat pump fits that pattern perfectly, giving you air conditioning from roughly March through November and efficient heating through the cooler months, all from a single outdoor unit.
F & R Air Conditioning has served communities across Acadiana since 1956. We make the drive to Sunset regularly, and our technicians understand the specific demands that St. Landry Parish’s climate and housing stock place on HVAC equipment.
How a Heat Pump Saves Money in Sunset
The basic principle: a heat pump moves heat rather than creating it. In summer, it functions identically to a traditional air conditioner. In winter, it reverses direction, extracting heat energy from outdoor air and transferring it inside. Because it’s moving energy rather than converting fuel into heat, the process uses significantly less electricity than any form of resistance heating and less money than burning natural gas or propane.
Sunset’s winters stay above freezing for all but a handful of nights each year. That’s important because heat pump efficiency is directly tied to outdoor temperature. Above 30 degrees, your system operates at two to three times the efficiency of electric strip heat. Below 20 degrees, efficiency drops and backup heat kicks in. But those sub-20 nights are rare here, maybe five or six per winter.
The net result for most Sunset homeowners who switch from a furnace-and-AC combination: a combined heating and cooling cost reduction of 25 to 40 percent.
Handling the Occasional Hard Freeze
Every few winters, a cold front pushes through and drops temperatures into the low 20s or teens for a night or two. Modern heat pumps handle this with built-in electric backup strips that activate automatically when the outdoor temperature drops below a set threshold. You won’t notice the transition, and your home stays warm.
If your home already has a gas furnace in working condition, a dual-fuel system is another option. This pairs the heat pump with your furnace, using the heat pump for efficient heating above 35 degrees and switching to gas below that point. It gives you the best of both technologies and keeps your existing furnace earning its keep.
Selecting the Right Equipment
Capacity
We size every heat pump using a Manual J load calculation. This accounts for your home’s insulation, window area, ceiling height, orientation, ductwork, and the number of people living there. An oversized system short-cycles, wasting energy and failing to remove humidity. An undersized system runs constantly and can’t maintain comfort on the hottest days. Manual J gives us the accurate capacity target.
Compressor Type
Single-stage heat pumps are the entry point. They run at full output and cycle on and off. Adequate for smaller homes and tighter budgets.
Two-stage units run at a lower capacity most of the time, stepping up to full power only when needed. The lower stage runs longer cycles, which pulls more moisture from the air. In St. Landry Parish’s humid climate, this translates to noticeably drier indoor air.
Variable-speed systems continuously adjust output to match conditions. They’re the quietest, most efficient, and best at humidity control. The premium is real, but so is the comfort improvement.
Brand Options
As a Lennox® Premier Dealer, we install the full Lennox heat pump range. We also carry Trane, Amana, and Ruud. We recommend equipment based on your home, your budget, and the specific performance features that matter most. We’re not locked into pushing one brand for every situation.
What the Installation Looks Like
For a straightforward replacement, installation takes about one day. We remove the old equipment, position the new outdoor unit, install the indoor air handler, connect refrigerant lines, wire the system to your thermostat and electrical panel, and seal all duct connections.
Conversions from a furnace-and-AC setup to a heat pump may take a day and a half, depending on the indoor equipment changes needed. We handle any local ductwork modifications and verify the electrical panel can support the new system.
Every installation ends with a full commissioning. We measure refrigerant charge, airflow, temperature differential, and thermostat response. The system has to meet manufacturer specifications before we consider the job complete.
