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 are fueled by electricity. 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?
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 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 continues after the reset, it's best to call a qualified HVAC technician for diagnosis and repair..
Why is my furnace making strange noises?
Strange noises 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 a buildup of sediment in the heat exchanger.
Squealing or screeching: Often a sign of a problem with the blower motor or other moving parts.
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: Often caused by a problem with the blower motor or inducer motor.
If your furnace is making strange noises, it is best 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 won't adequately heat the space. An too-large furnace will short cycle, causing wear and tear, inconsistent heating, and inflated utility bills. Here are some signs your furnace may be improperly sized:
High Energy Bills: An oversized 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 hot and cold spots, 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. Ask a professional for a load calculation to confirm appropriate sizing. Installing the correct size unit will maximize efficiency and minimize energy bills.
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 These are a good option in areas where natural gas isn't accessible.
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 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).

Why is my furnace making strange noises?
Strange noises from your furnace can indicate a variety of problems, from minor issues to major malfunctions. :
Banging or popping: Could indicate dirty burners, delayed ignition, or expanding ducts.
Squealing or screeching: Often indicates an issue with the blower motor or other moving parts.
Rumbling or vibrating: Might suggest a loose or damaged component or a problem with the burner.
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: Often caused by a problem with the blower motor or inducer motor.
If your furnace is making strange noises, it is best 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 undersized 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. Here are some signs your furnace may be improperly sized:
High Energy Bills: An oversized furnace can lead to increased energy consumption.
Inconsistent Temperatures: Noticeable temperature fluctuations 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: A furnace that's too large 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.. Installing the correct size unit will maximize efficiency and minimize energy bills.
