How do I reset my furnace?

If your furnace isn't working correctly, a simple reset can sometimes resolve the issue. Here's how to reset most furnaces:
  1. Turn off the furnace: Set the thermostat to the 'off' position.
  2. Turn off the power: Locate the circuit breaker for your furnace and switch it off.
  3. Wait: Wait a few minutes for the system to reset.
  4. Turn the power back on: Flip the circuit breaker back to the 'on' position.

What is a pilot light?

A pilot light is a tiny flame used to ignite the main burners. When the thermostat signals for heat, the pilot light ignites the main burners, heating the air. . While pilot lights are generally reliable, they can sometimes go out or malfunction, requiring relighting or repair. Electronic ignition systems are usually safer and more efficient.

How can I tell if my furnace is the correct size for my home?

A correctly sized furnace is crucial for optimal home comfort. An too-small furnace won't adequately heat the space. An oversized furnace will short cycle, causing wear and tear, inconsistent heating, and inflated utility bills. Signs that your furnace may not be correctly sized include::
  • High Energy Bills: An incorrectly sized furnace can lead to increased energy consumption.
  • Inconsistent Temperatures: Noticeable temperature differences between rooms.
  • Short Cycling: If your furnace cycles frequently, it may not be heating your space efficiently and wasting energy.
  • Poor Air Quality: If the airflow from the vents seems weak or there are hot and cold spots, the unit may be the wrong size.
  • Excessive Noise: Oversized furnaces may produce more noise than normal.
A qualified technician will be able to assess your home's heating needs. Ask a professional for a load calculation to confirm appropriate sizing. A proper sizing calculation is a worthwhile investment for optimal comfort and energy efficiency.

Why is my furnace blowing cold air?

Several problems can cause your furnace to blow cold air::
  • Pilot light or ignition problems: If the pilot light is out, the burners won't light, and the furnace won't produce heat. In newer furnaces, a faulty electronic ignition system can prevent the burners from igniting.
  • Thermostat issues: An incorrectly set or malfunctioning thermostat can prevent the furnace from turning on or cause it to blow cold air. Check that your thermostat to ensure the system is set to 'heat' and the temperature setting is higher than the current room temperature.
  • Overheating: If the furnace overheats, a safety switch may shut off the burners, causing the blower to circulate cold air.. Overheating can also damage your furnace, so it's best to have a professional inspect the system.
  • Ductwork problems: Seal any ductwork leaks to improve performance. Poorly insulated or leaky ducts can cause a variety of heating issues.
