Having problems with your heating system? Get answers to common questions about furnace repair so you can make informed decisions.
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 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. 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?
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 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 persists 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, from minor issues to major malfunctions. :
Banging or popping: Could indicate dirty burners, delayed ignition, or expanding ducts.
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 from the igniter, but it can also come from other electrical problems 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 efficient and comfortable heating. An undersized furnace won't adequately heat the space. 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 cause 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 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.. Installing the correct size unit will maximize efficiency and minimize energy bills.

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.. They are typically less expensive to purchase than gas furnaces, but they can be more expensive to operate depending on your electricity rates.

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 continues after the reset, don't attempt to diagnose or repair the issue yourself.

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: 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 optimal home comfort. An undersized furnace won't adequately heat the space. An oversized 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 lead to increased energy consumption.
Inconsistent Temperatures: Noticeable temperature differences between rooms.
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 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. 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.
