When Your Furnace Goes, the Problem Is Rarely Just Mechanical

A furnace that’s reaching the end of its life or has been poorly maintained consumes more energy, breaks down at the worst times, and can pose combustion risks on gas models. An aging unit that’s 15 to 20 years old often costs more in annual repairs than a full replacement would in monthly payments through Financeit.

Parts that are hard to source or have long lead times

Four black circles in a loop with curved arrows forming a circular cycle

Short-cycling (frequent start-stop cycles)

Black vertical bars of varying heights on a white background, resembling an audio waveform icon

Unusual noise or odour at startup

Black line icon of an outdoor air conditioner unit with a fan and vents

System over 15 years old with no regular maintenance

Invoice with dollar sign icon, representing billing or payment document

Heating bills rising steadily without explanation
