Heating Repair for Duson Homeowners
Need heating repair in Duson? F & R Air Conditioning diagnoses and fixes furnaces and heat pumps across western Lafayette Parish, often the same day during a cold snap. Duson sits along I-10 between Lafayette and Rayne, and at around 1,700 residents, local HVAC options are thin. Most contractors servicing the town drive in from Lafayette or Crowley, and not all of them prioritize a small-town call the way they would a job in a bigger market.
We treat every service call the same, whether it’s a large commercial building in Lafayette or a single-family heater repair in Duson. We’ve been doing this across Lafayette Parish since 1956, and Duson has always been part of our regular service territory.
The Heating Systems in Duson Homes
Most residential heating in Duson falls into two categories:
Heat pumps with electric backup. This is the standard setup for homes built from the 1980s onward. The heat pump handles heating until outdoor temperatures drop below about 35°F, then electric heat strips in the air handler kick in as supplemental heat. These systems work well for our climate, but failures in either the heat pump or the backup strips can leave you uncomfortable or stuck with enormous electric bills.
Gas furnaces. Some Duson homes, especially those built in the 1960s and 1970s, have natural gas furnaces. These deliver warmer supply air than heat pumps (typically 120-140°F from the vents versus 90-100°F from a heat pump), which many homeowners prefer. The tradeoff is that furnaces require more maintenance and have safety-critical components like the heat exchanger that must be inspected regularly.
Repair Situations We Handle Regularly
- Furnace that clicks but won’t ignite (usually an ignitor or flame sensor)
- Heat pump running in cooling mode when set to heat (reversing valve or thermostat wiring)
- System blowing lukewarm air (low refrigerant charge, dirty coils, or failed heat strips)
- Blower motor not running (capacitor failure, motor burnout, or control board issue)
- System short-cycling (turning on and off repeatedly, often caused by overheating from restricted airflow)
Why Your Filter Matters More Than You Think
Duson homes tend to have a lot of outdoor activity nearby. Between the agricultural land surrounding the town and I-10 traffic dust, air filters in this area get dirty faster than in more urban settings. A clogged filter is the most common preventable cause of heating failure we encounter.
In a furnace, a dirty filter restricts airflow across the heat exchanger. The exchanger overheats, the high-limit safety trips, and the furnace shuts down. In a heat pump, restricted airflow causes the indoor coil to drop below freezing, which ices over the coil and blocks airflow entirely. Either way, a $5 filter could have prevented a $200 service call.
Check your filter monthly during heating season. If you can’t see light through it, replace it.
