How Does Your HVAC Ignition Affect Your Unit?

HVAC ignition

Among the various technology incorporated into an HVAC unit, ignition components that fire up the burners in a gas furnace are among the most critical. Electric furnaces utilize electrical heating elements that produce warmth. However, gas heating requires a fail-safe method to ignite the gas that produces the flame that generates the heat. In today’s gas furnaces, two types are most common: a standing pilot light and electronic ignition. Here’s how the two methods differ.

Pilot vs. Electronic HVAC Ignition

Pilot lights have been utilized for more than a century and have a time-tested record of service. However, there’s a downside: A pilot burns continuously, typically consuming about 600 to 800 BTUs of gas every 24 hours. While this added expense is not terribly excessive, monthly gas-utility bills are rising all the time.

Electronic ignition is now the accepted standard for safety and reliability in gas furnaces. The device consumes no gas and uses only a momentary burst of electrical power when the igniter actuates. On the minus side, an electronic igniter is susceptible to wear and tear after many years. Mainly, this is expansion and contraction, causing the igniter to crack and require replacement.
