Why do I need my furnace inspected?

Furnaces, especially newer ones, are designed to last a long time—usually as long as 10 – 15 years. But even the most well designed system might run into problems, especially during the spring and summer when it’s sitting idle for months at a time. A furnace inspection from Michael Bonsby HVAC & Plumbing is basically a checkup of your system, where we’ll perform basic maintenance tasks including:

  • Inspecting the exhaust flue
  • Inspecting the inducer housing for cracks
  • Inspecting all burners
  • Inspecting the heat exchanger
  • Testing for gas leaks or carbon monoxide
  • Ensuring proper combustion air levels
  • Testing high-limit/auxiliary limit switches
  • Testing the pressure switch
  • Testing for proper gas pressure
  • Testing igniter resistance
  • Testing motor amps
  • Ensuring proper fan speed
  • Testing motor capacitor MFD
  • Testing inducer motor amps
  • Cleaning pressure switch barb
  • Cleaning flame sensor/thermocouple
  • Checking filter
  • Checking air flow (evaporator coil cleanliness)
  • Checking cleanliness of blower fan
