Heating Repair at the Gateway to the Atchafalaya
Henderson sits right on the edge of the Atchafalaya Basin, and that location brings some of the most extreme humidity conditions in all of Acadiana. The moisture levels here, especially during the transition months of fall and spring, are hard on every piece of mechanical equipment in your home, including your heating system.
F & R Air Conditioning serves Henderson as part of our coverage across St. Martin Parish. We’ve been working on heating and cooling systems in this region since 1956, and we understand how basin-adjacent conditions affect your equipment differently than homes even a few miles inland.
How Basin Humidity Affects Your Heater
When people think about humidity damage, they usually think about summer. But heating systems in Henderson face moisture-related problems year-round.
During the months your heater sits idle (roughly March through October), condensation forms on metal surfaces inside the air handler and furnace cabinet. In Henderson, this condensation cycle is more aggressive than in drier areas because the ambient humidity rarely drops below 70%, even in the cooler months. The result:
- Flame sensors develop an oxide layer that prevents them from detecting the pilot or burner flame. The furnace lights briefly, then shuts down.
- Electrical relays and contactors corrode at the contact surfaces. You might hear clicking sounds as the system tries to start, but the contacts can’t make a solid connection.
- Control boards develop corrosion on solder joints and circuit traces. This can cause erratic behavior: the system works sometimes but not others, or it runs a partial cycle before shutting down unexpectedly.
Gas Furnace Concerns Near the Basin
Henderson has a number of homes with gas furnaces, and the combination of high humidity and gas combustion creates a corrosive environment inside the furnace cabinet. Combustion produces water vapor as a byproduct, and when that vapor encounters already-humid ambient air, moisture accumulates on the heat exchanger, flue pipe, and burner assembly.
We always inspect the heat exchanger during furnace repair calls in Henderson. A compromised heat exchanger in a gas furnace is a carbon monoxide hazard, and the accelerated corrosion in this area means heat exchangers can fail sooner than their expected lifespan.
Heat Pump Defrost Issues
Heat pumps in Henderson are particularly prone to defrost cycle problems. The high humidity means the outdoor coil frosts over more frequently and more heavily than in drier climates. If the defrost control, defrost timer, or reversing valve isn’t functioning correctly, ice accumulates rapidly on the outdoor unit.
Signs of a defrost problem:
- A visible block of ice on the outdoor unit
- Reduced or no warm air from your vents
- The outdoor fan running but the system not heating
- Higher-than-normal electric bills (the backup heat strips are doing all the work)
We carry defrost boards and reversing valve solenoids on our trucks, so these repairs are often completed in a single visit.
