The appearance of an igniter depends entirely on the appliance. The most common type is the Hot Surface Ignitor (HSI), which looks like a small, flat, dark gray or black ceramic rod (or coil/loop) that resembles the filament inside a lightbulb.
The best time to buy a furnace is during the off-season, specifically late spring (April-May) or early autumn (September-October), when HVAC companies are less busy and offer lower prices, rebates, or promotions. Purchasing in these shoulder seasons ensures faster installation times and better negotiating power compared to winter peak season.
The heat exchanger is often considered the most costly part of a furnace to repair or replace. It is a critical component that transfers heat from the combustion process to the air that circulates throughout your home. Over time, heat exchangers can crack due to the constant heating and cooling cycles they undergo.
Disconnect and Remove the Old Ignitor: Unplug the wire connector for the ignitor and carefully unscrew the bracket holding it in place. Install the New Ignitor: Screw the new ignitor into place and connect the wiring. Safety Reminder: Never touch the gray or black part of the new ignitor with your bare hands.
Igniter replacement costs range from $150 to $425 on average for professional repair, depending on the appliance and your location. While parts are relatively inexpensive, labor and diagnostic fees make up the bulk of the final bill.
What fails first on a furnace? The most common early failures are the furnace ignitor or flame sensor, as they experience regular wear and tear and are critical to starting the heating cycle.
Try the Salvation Army, a local church, or a community action agency. Their rules may be different. Ask About Payment Plans: Many local HVAC contractors, including Smart Climate Solutions, offer payment plans for urgent repairs because we believe everyone deserves a warm home.
Yes, you should highly consider replacing a 30-year-old furnace. Most furnaces have a lifespan of 15 to 20 years. At 30 years old, your system has likely outlived its expected life. It is operating at a much lower efficiency than modern units and presents a significantly increased risk of catastrophic breakdown or dangerous carbon monoxide leaks.
A good rule of thumb for energy-saving heating temperature is to set your thermostat at 68 degrees Fahrenheit. For more comfort, try increasing the temperature by 1 or 2 degrees at a time. For energy savings, turn the temperature down 1 or 2 degrees at a time.
Yes HVAC prices have steadily increased over the past few years, and 2026 is no exception. These increases are affecting everything from entry-level systems to high-efficiency units, making it more expensive than ever to install or replace HVAC systems.
A standard furnace needs to be replaced every 15 to 20 years. However, electric models can occasionally last up to 30 years, while lack of maintenance or severe climates can shorten this lifespan.
A bad hot surface furnace igniter typically has a noticeable hairline fracture, a white burned-out streak, or visible blistering and black spots on its surface. It can also look completely intact but fail to glow a bright orange-yellow when the furnace cycles.
A furnace that won't ignite is usually caused by a tripped circuit breaker, a dead thermostat battery, a clogged air filter, a dirty flame sensor, or a faulty igniter.
It's possible for a furnace to still run with a faulty ignitor, yet the air coming from the vents will be cold, not warm. Unless the ignitor lights the burners to burn fuel, your furnace won't have warm air to distribute around your home or business.
To qualify, you must: Be the homeowner and occupy the house. Be unable to obtain affordable credit elsewhere. Have a household income that does not exceed the very low limit by county.
Most furnace issues stem from a few common culprits. The easiest to check yourself are clogged air filters and thermostat errors, which usually cause the system to blow cold air, run inefficiently, or cycle on and off constantly. Other frequent problems include dirty flame sensors or failing blower motors.
Foundation repair is generally the most expensive home repair, potentially costing over $30,000 for major lifting and stabilization. Other top-tier, high-cost repairs include complete roof replacements, major water damage remediation, and replacing underground sewer lines, often running into tens of thousands of dollars.
Capacitors are used in nearly every heating system, from gas furnaces to electric furnaces to heat pumps. Even though other parts can fail, like the ignitor in a gas furnace or the compressor in a heat pump, the capacitor is by far the most common part to fail on a furnace because almost every system relies on one.
To get your furnace to kick on, first verify your thermostat is set to "Heat" and raised at least 5 degrees above room temperature. Next, check that the furnace power switch (usually resembling a standard light switch on or near the unit) is toggled "ON".
5 Warning Signs It's Time for Furnace Replacement
The Short Answer Is: Warning signs of a bad furnace ignitor include the furnace not starting or heating, a noticeable clicking sound without ignition, or frequent short cycling where the furnace turns on and off rapidly. Additionally, if the ignitor appears cracked or discolored, it may need replacement.
Broken ceramic insulation on the spark electrode may result in the gas stove igniter not sparking against the burner head. Replace the electrode if the ceramic insulation is broken. If the electrode is okay, you may need to replace the igniter switch or spark module.
