What the Technician Does During a Service Call

When a technician arrives at your Lafayette home, they begin by testing the thermostat, inspecting the burner assembly, and checking the flame sensor or igniter depending on your furnace type. For gas furnaces, this includes examining the gas valve and ensuring proper combustion. For electric units, the technician tests heating elements and electrical connections. Oil furnaces require inspection of the fuel line, nozzle, and combustion chamber.


After the repair is completed, you will notice that the furnace ignites reliably, heats the home evenly, and maintains the temperature set on the thermostat. The system will also stop cycling on and off repeatedly, and you should no longer hear unusual clicking, banging, or humming sounds during operation.


Maintenance plans include seasonal tune-ups, filter replacements, and safety inspections to catch small issues before they lead to a full system failure. The service does not include ductwork replacement or whole-system installations, but those options can be discussed if your furnace is beyond repair or no longer meets your heating needs.

What to expect before the technician arrives

Homeowners in Lafayette usually want to know what the technician will check, how long repairs take, and whether their furnace can be fixed or needs to be replaced.

  • What types of furnaces do you service?

    The team services and repairs gas, electric, and oil furnaces from most manufacturers. They have experience with older units as well as newer high-efficiency models.

  • How long does a furnace repair usually take?

    Most repairs are completed in one visit and take between one and three hours. If a part needs to be ordered, the technician will provide a timeline and schedule a follow-up appointment.

  • What does a furnace tune-up include?

    A tune-up includes inspecting the igniter or pilot light, cleaning the burner assembly, testing the thermostat, checking electrical connections, and replacing the air filter. This helps the furnace run safely and efficiently throughout the heating season.

  • Why is my furnace blowing cold air?

    Cold air from the vents usually means the igniter is not lighting the burner, the pilot light is out, or the thermostat is set incorrectly. The technician will diagnose the cause and make the necessary repairs.

  • When should I replace my furnace instead of repairing it?

    If your furnace is more than fifteen years old, requires frequent repairs, or has a cracked heat exchanger, replacement is usually the better option. The technician will explain what makes sense based on the age and condition of your system.
