The fan limiter switch is an essential safety feature that safeguards your furnace from overheating. It has sensors that turn off the fan motor when it gets too hot, preventing the engine from being damaged. The cost of furnace repairs depends on a variety of factors, including the type and manufacturer of the furnace, the complexity of the repairs, the accessibility of the furnace, the labor of the local HVAC professional, and the parts required. Common repairs and replacements include thermostat, fan motor, draft inductor motor, igniter replacement, thermocouple replacement, flame sensor, gas valve, control board or circuit, condenser, exhaust pipe, chimney lining, relay or high limit switches, pressure switch, transformer, oil combustion chambers, heat exchanger, coils, and filter.
An HVAC expert can assess any issues with the furnace and make the necessary repairs to reduce heating costs and increase energy efficiency. When deciding between repair costs and replacement costs for HVAC units, homeowners should consider the age of the unit and the cost of repairs. If the system is relatively new and the cost of repairs is significantly lower than the cost of replacing it, it is generally advisable to choose repairs. However, if the heat exchanger is broken there is a risk of carbon monoxide leaks and it may be more cost-effective to replace the unit. It's important to plan for furnace repair costs as they can add up quickly. Homeowners may be able to perform some boiler maintenance tasks themselves such as replacing the filter or cleaning an outdoor HVAC unit.
However, boiler repairs and replacement of parts will normally need to be done by an experienced professional. It's also recommended that homeowners ask their HVAC professional if they offer discounts or promotions to help customers save on HVAC service costs. With all this in mind, homeowners can make an informed decision about whether to repair or replace their furnace.
