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. 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?
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, 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 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 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: 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 incorrectly sized furnace can lead to increased energy consumption.
Inconsistent Temperatures: Noticeable temperature fluctuations between rooms.
Short Cycling: If your furnace cycles 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
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.
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 These are a good option in areas where natural gas isn't accessible.
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.
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).

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

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 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. 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 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: A furnace that's too large 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.
