Furnace Inspection Services

If you’re concerned about the state of your furnace, don’t hesitate to call us here at RL7 Mechanical Ltd so we can put your mind at ease!

Furnace inspections can vary depending on what type of furnace you have. Generally, our team will check the following items for performance and safety:

  • Check the vent system for any leaks or blockages
  • Examine the heat exchanger for signs of corrosion and cracks or separations; a damaged heat exchanger can allow deadly carbon monoxide to escape
  • Remove and check the blower wheel, cleaning its components and clearing it of dirt and debris 
  • Test the blower access door to ensure it is tightly sealed
  • Check the air intake grills for blockages
  • Perform an amp-draw test; the results should be within the unit’s listed specifications
  • Check the burner for proper ignition and testing the flame sensor for accurate operation
  • Lubricating all the motor’s moving parts to reduce friction
  • Check that all electrical connections are tight and examining the wiring for signs of rust and corrosion
  • Test the thermostat calibration
  • Examine the flue for obstructions
  • Test the unit’s safety controls, including the high limit control to ensure the furnace does not overheat
  • Check the belts for signs of wear or cracks
  • Test the system’s start-up cycle
  • Check the furnace’s air filter

These checks not only ensure that your furnace is running optimally, but also that it is not in danger of damaging your home through fire or toxic fumes. A perfectly running furnace also helps you save on bills! A correctly calibrated thermostat means that the furnace is expelling the exact amount of heat needed to warm your home, rather than overheating and driving up your monthly costs. We understand that this is a bit of a complicated process, so feel free to ask us questions!


Once our qualified technicians completely diagnose your furnace, we will inform you about its condition and suggest suitable repair services. We also suggest preventative maintenance to help prolong the life and efficiency of your furnace.
