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 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.. 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?
If your furnace isn't working correctly, a simple reset can sometimes resolve the issue. 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 persists or if you encounter error codes, it's best to call a qualified HVAC technician for diagnosis and repair..
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 indicate dirty burners, delayed ignition, or expanding ducts.
Squealing or screeching: Often indicates an issue 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: Could be from the igniter, but it can also come from other electrical problems If the clicking sound is persistent, it is best to contact an HVAC technician.
Whining: Often caused by a problem with the blower motor or inducer 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 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 fluctuations throughout your home.
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 can make loud or unusual sounds
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.
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 burn heating oil as fuel, which is stored in a tank. 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).

Banging or popping: Could be due to 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.
If your furnace is making unusual sounds, it is best to contact a qualified HVAC technician for diagnosis and repair. 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?
