Sunset Heating Repair
Sunset is a quiet community of about 2,900 in St. Landry Parish, known for the best boudin in Louisiana and a slower pace of life. What Sunset doesn’t have a lot of is local HVAC options. When your heater stops working, you’re likely calling a company from Opelousas, Carencro, or Lafayette, and hoping they’ll prioritize your call.
F & R Air Conditioning has been serving St. Landry Parish communities since 1956. Sunset is firmly within our service territory, and we treat every call here with the same urgency we bring to a job in Lafayette. Your comfort matters regardless of your town’s population.
Understanding Your Heating System
If you’re not sure what type of heating system you have, here’s a quick way to tell. Walk outside and look at your outdoor unit:
- If you have a large outdoor unit that runs in both summer and winter, you have a heat pump. It cools your home in summer and heats it in winter by reversing the refrigerant flow.
- If your outdoor unit only runs in summer, and your heating comes from an indoor unit with gas piping, you have a gas furnace for heating and a separate air conditioner for cooling.
- If you have a large outdoor unit AND visible gas piping to an indoor unit, you likely have a dual-fuel system: a heat pump that handles moderate cold, with a gas furnace that takes over during extreme cold.
Knowing this helps us prepare before we arrive, and it helps you understand the repair we recommend.
Heat Pump Heating Failures
In Sunset, most homes built after the 1990s use heat pumps. The most common heating-specific failures:
The system won’t switch to heat mode. This is typically a reversing valve problem. The valve uses a solenoid coil to shift a sliding mechanism inside the valve body. When the solenoid fails or the internal mechanism sticks, the system stays in cooling mode even when the thermostat calls for heat. You’ll feel cold air from the vents.
Ice on the outdoor unit during winter. A thin layer of frost during cold, humid weather is normal. A thick coating of ice that doesn’t melt is not. The system has a built-in defrost cycle that’s supposed to periodically warm the outdoor coil and melt accumulated frost. When the defrost timer, defrost thermostat, or defrost control board fails, ice builds up until the unit can’t function.
Gas Furnace Heating Failures
For Sunset homes with gas furnaces, the failures tend to be related to components that sit idle for most of the year:
No ignition. The ignitor cracked, the flame sensor is fouled, or the gas valve is stuck closed. These are the three most common causes of a gas furnace that won’t light.
Short cycling. The furnace starts, runs for a minute or two, then shuts off. This repeats endlessly without the house ever reaching temperature. Common causes include a dirty filter (causing the heat exchanger to overheat and trip the high-limit switch), a failing blower motor (same result), or a cracked heat exchanger (the rollout switch detects flames where they shouldn’t be and shuts the system down).
Winter Preparedness in St. Landry Parish
Sunset sits inland enough that winter cold fronts can be more pronounced here than along the coast. Morning temperatures in the low 20s aren’t rare during January cold snaps. Having your heating system checked before the season starts is the best insurance against a breakdown when you need heat most.
