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 tend to be efficient and have lower operating costs compared to oil or propane furnaces.
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 use electric resistance heating elements to generate heat.. They are typically less expensive to purchase than gas furnaces, but they can be more expensive to operate depending on your electricity rates.

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

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 a few minutes 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 continues 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, from minor issues to major malfunctions. :

Banging or popping: Could be due to dirty burners, delayed ignition, or expanding ducts.
Squealing or screeching: Often a sign of a problem with the blower motor or other moving parts.
Rumbling or vibrating: Check for loose parts or components.
Clicking: Could 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 essential for efficient and comfortable heating. An undersized furnace won't adequately heat the space. An too-large furnace will cycle on and off too frequently, wasting energy and shortening the system's lifespan.. Signs that your furnace may not be correctly sized include::

High Energy Bills: An oversized furnace can cause increased energy consumption.
Inconsistent Temperatures: Noticeable temperature fluctuations between rooms.
Short Cycling: If your furnace turns on and off 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. 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.

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 tend to be efficient and have lower operating costs compared to oil or propane furnaces.
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. 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.. They are typically less expensive to purchase than gas furnaces, but they can be more expensive to operate depending on your electricity rates.

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 reset.
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 continues after the reset, it's best to call a qualified HVAC technician for diagnosis and repair..

If your furnace is making unusual sounds, recommended to have the system inspected. Ignoring unusual sounds can lead to further damage or costly repairs down the road.

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

A properly sized furnace is essential for optimal home comfort. An too-small furnace will constantly run and struggle to heat your home effectively, especially in cold weather.. 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 between rooms.
Short Cycling: If your furnace turns on and off 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.
