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 burn heating oil as fuel, which is stored in a tank. They require more maintenance and tend to be less efficient than gas furnaces.
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 do I reset my furnace?

Before calling for repairs, consider resetting your furnace. Here's how to reset most furnaces:

Turn off the furnace: Set the thermostat to the 'off' position.
Turn off the power: Locate the circuit breaker for your furnace and switch it off.
Wait: Wait at least 30 seconds, though longer is sometimes recommended for the system to fully power down.
Turn the power back on: Flip the circuit breaker back to the 'on' position.
Turn on the furnace: Turn the thermostat back on and set it to your desired temperature.

If the problem persists or if you encounter error codes, don't attempt to diagnose or repair the issue yourself.

Why is my furnace making strange noises?

Unusual sounds from your furnace can indicate a variety of problems, it's important to pay attention to these sounds to identify potential issues early on:

Banging or popping: Could be due to a buildup of sediment in the heat exchanger.
Squealing or screeching: Often indicates an issue with the blower motor or other moving parts.
Rumbling or vibrating: Check for loose parts or components.
Clicking: May be caused by a faulty igniter, control board, or other electrical components. If the clicking sound is persistent, it is best to contact an HVAC technician.
Whining: Similar to squealing or screeching, this indicates an issue with a motor.

Addressing the issue early can often save you from a larger expense later.

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

A properly sized furnace is crucial for efficient and comfortable heating. An undersized furnace will constantly run and struggle to heat your home effectively, especially in cold weather.. An oversized furnace will cycle on and off too frequently, wasting energy and shortening the system's lifespan.. Here are some signs your furnace may be improperly sized:

High Energy Bills: An incorrectly sized furnace can cause increased energy consumption.
Inconsistent Temperatures: Noticeable temperature differences throughout your home.
Short Cycling: If your furnace turns on and off frequently, it could be an indication and wasting energy.
Poor Air Quality: If the airflow from the vents seems weak or there are areas with inconsistent temperatures, the unit may be the wrong size.
Excessive Noise: A furnace that's too large may produce more noise than normal.

If you suspect your furnace is improperly sized, it's essential to consult with an HVAC professional. 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.

What are the different types of furnaces?

The most common types of furnaces are classified by their fuel source:

Natural Gas Furnaces: fueled by natural gas 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 burn heating oil as fuel, which is stored in a tank. They require more maintenance and tend to be less efficient than gas furnaces.
Electric Furnaces: Electric furnaces use electric resistance heating elements to generate heat.. Their installation cost is usually lower, but electricity prices can affect operating costs significantly.

An HVAC professional can help you determine the best type of furnace for your home or business.

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:

Why is my furnace making strange noises?

Unusual sounds from your furnace can indicate a variety of problems, from minor issues to major malfunctions. :

Banging or popping: Could indicate a buildup of sediment in the heat exchanger.
Squealing or screeching: Often a sign of a problem with the blower motor or the inducer motor.
Rumbling or vibrating: Might suggest a loose or damaged component or a problem with the burner.
Clicking: May be caused by a faulty igniter, control board, or other electrical components. Electrical issues can be hazardous, so contact a professional.
Whining: Similar to squealing or screeching, this indicates an issue with a motor.

Addressing the issue early can often save you from a larger expense later.

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 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 cause increased energy consumption.
Inconsistent Temperatures: Noticeable temperature fluctuations throughout your home.
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 areas with inconsistent temperatures, the unit may be the wrong size.
Excessive Noise: Oversized furnaces can make loud or unusual sounds

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.
