Frequently Asked Questions about Furnace Repair

Is your furnace acting up? Get answers to common questions about furnace repair so you can make informed decisions.

What is a pilot light?

A pilot light is a small, continuous flame used in older furnaces. When the thermostat signals for heat, the pilot light ignites the main burners, heating the air. . While pilot lights are generally reliable, they're not as efficient as newer ignition systems They also consume a small amount of gas continuously, even when the furnace is not actively heating. .

Why is my furnace blowing cold air?

Several problems can cause your furnace to blow cold air::
  • Pilot light or ignition problems: In older furnaces, the pilot light needs to be lit for the burners to ignite. 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 make it 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: Leaks in your ductwork can allow heated air to escape into unconditioned spaces, reducing the amount of warm air that reaches your rooms.. This can also result in the furnace blowing cold air, especially if the leak is near the beginning of the ductwork run.
If your furnace is blowing cold air, it's important to troubleshoot the problem and, if necessary, call a qualified HVAC technician for repair.

What are the different types of furnaces?

The most common types of furnaces are classified by their fuel source:
  • Natural Gas Furnaces: These are the most popular type, fueled by natural gas, which is generally readily available and relatively affordable in many areas. Natural gas furnaces offer cleaner energy, especially compared to oil.
  • Propane Furnaces: Propane furnaces are similar to natural gas furnaces but run on propane, which is stored in a tank on your property..
  • Oil Furnaces: Oil furnaces are less common than gas or propane furnaces but still used in certain regions. Oil units may require additional considerations for fuel storage and delivery.
  • Electric Furnaces: Electric furnaces are fueled by electricity. Their installation cost is usually lower, but electricity prices can affect operating costs significantly.
Other less common types of furnaces include modulating furnaces (which offer variable heating output for better efficiency) and dual-fuel or hybrid systems (which combine a heat pump with a furnace for enhanced performance in all climates).

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

A correctly sized furnace is essential for efficient and comfortable heating. An undersized furnace will constantly run and struggle to heat your home effectively, especially in cold weather.. An too-large 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 oversized furnace can lead to increased energy consumption.
  • Inconsistent Temperatures: Noticeable temperature differences between rooms.
  • Short Cycling: If your furnace cycles frequently, it could be an indication 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.
If you suspect your furnace is improperly sized, it's essential to consult with an HVAC professional. A Manual J load calculation can accurately determine the appropriate furnace size.. A proper sizing calculation is a worthwhile investment for optimal comfort and energy efficiency.
