Frequently Asked Questions about Furnace Repair

What causes a furnace to stop working?

There are many potential causes of furnace failure, from minor issues to major breakdowns. Some of the most common causes include::

• Lack of power: Check the circuit breaker to ensure the furnace is receiving power. Make sure the power switch near the furnace is also on.
• Thermostat problems: Check that the thermostat is set correctly to 'heat' and at a temperature higher than the current room temperature. Replace batteries if the display is blank or not working. Try resetting the thermostat or replacing the batteries. If that doesn't solve the problem, the thermostat may need to be replaced.
• Clogged air filter: A clogged air filter can cause many problems. Try replacing the filter.
• Ignition problems: Issues with the igniter or pilot light can prevent the furnace from starting. In newer furnaces, electronic ignition systems control this process and should be checked if there are problems.
• Blower motor issues: The blower motor circulates air through the furnace and ductwork. A faulty motor can prevent air from circulating properly..
• Gas supply problems (for gas furnaces): Make sure the gas supply valve to the furnace is turned on.. Check that there are no gas leaks.
• Other component failures: Other components, such as the inducer motor, capacitor, or pressure switch, might be responsible.

It is typically best to avoid trying to fix the furnace on your own unless you're a qualified HVAC professional.

What is the difference between a single-stage and two-stage furnace?

Single-stage and two-stage furnaces differ in their heating output capabilities:
Single-stage furnaces operate at only one output level – full capacity. This can lead to temperature fluctuations and higher energy bills because the furnace is either running at its maximum setting or completely off..
Two-stage furnaces offer two levels of heat output: a lower setting for mild weather and a higher setting for colder temperatures. This allows the furnace to modulate its output based on the actual heating demand, resulting in more consistent temperatures, quieter operation, and improved energy efficiency. A two-stage furnace may be a more expensive initial investment, but it can provide greater comfort and savings over time.

What is a pilot light?

A pilot light is a tiny flame used to ignite the main burners. It's how older furnaces ignite the gas. Most modern furnaces use an electronic ignition system. While pilot lights are generally reliable, they can sometimes go out or malfunction, requiring relighting or repair. They also consume a small amount of gas continuously, even when the furnace is not actively heating. .

What are some tips for maintaining my furnace?

Regular furnace maintenance is key to preventing costly repairs and ensuring its efficient operation. Here are some tips:

• Change the air filter regularly (every 1-3 months): A dirty filter restricts airflow, reducing efficiency and potentially damaging the system.
• Schedule an annual furnace tune-up: A professional technician can inspect, clean, and test all components, ensuring optimal performance and safety.
• Keep the area around the furnace clear: Remove any flammable materials or obstructions that could block airflow.
• Check and clean the furnace vents: Make sure vents are not blocked by furniture or other items.
• Install a programmable thermostat: This helps optimize heating schedules and save energy.
• Seal air leaks around windows and doors: This prevents heat loss and improves efficiency.

Proactive maintenance can prevent unexpected breakdowns and reduce energy bills.
