A: In order to tell if your heating system is electric or gas, check the front of your heating unit. Through the small window on the front of the heater, you should be able to see a blue flame glowing. Gas heating units use burners to produce heat. You can usually also hear the sound of the gas burner.
Look around the exterior housing to find an attached metal plate that lists the model number and other information. If this plate does not specifically say whether the unit is a heat pump or an air conditioner, write down the model number. Next, search the unit's brand and model number online.
The most straightforward way to tell if your furnace is gas or electric is to check its fuel source. A gas furnace connects to a gas supply line. You can usually find a gas meter or gas pipes near it. On the other hand, electric furnaces don't require a gas supply and connect to your home's electrical system.
Cooling Components
A furnace does not have a built-in cooling component. It's a standalone heating system and cannot provide air conditioning or cooling capabilities. In hot climates, a separate air conditioning system is required. Conversely, an HVAC system includes both heating and cooling components.

The majority of North American households depend on a central furnace to provide heat. A furnace works by blowing heated air through ducts that deliver the warm air to rooms throughout the house via air registers or grills. This type of heating system is called a ducted warm-air or forced warm-air distribution system.
Pay attention to how often your heating system cycles on and off. Frequent cycling could be a sign of thermostat problems as it struggles to maintain the desired temperature. If the system stays on for extended periods without adequately warming the house then the furnace might be working inefficiently.
In a nutshell, a furnace heats your home. An HVAC system combines a furnace, air conditioner, and ventilation system (more on that below). So, if you need HVAC service, it may or may not include the furnace.
Most furnace heating systems in the U.S. use natural gas for combustion, but propane, oil and electric furnaces are used as well. Read more about gas vs. electric furnaces here. By selecting a heating system suited to your climate, you can enjoy better comfort and probably lower operating costs as well.
What Does a Furnace Look Like? Typically, a furnace has a rectangular shape, and the housing is made of metal. The intake side will have a spot for an air filter to prevent dust and debris from dirtying the inner workings. If it is a gas furnace, you will see a gas line running to it.
If you've located your hot water cylinder, we can now determine whether it runs on gas or electricity. The easiest way to determine if you have a gas hot water cylinder is by looking for its pilot light. The pilot light is a small blue flame that lights the main burner whenever the tank needs heating.
First, you can head on over to your heating unit. If it has a window where you can see a little blue flame inside, you have a gas HVAC system. An electric HVAC system does not need a flame or a window.
1. Split System. Heating and cooling split systems are the most common types of HVAC systems used in residential buildings. They consist of two separate components — one for heating and one for cooling — and use a traditional thermostat to control the temperature for the entire structure.
With a conventional furnace, natural gas is piped to a burner located inside a combustion chamber. There, the gas is mixed with air, then ignited by a pilot light, a spark, or a similar device controlled by a thermostat. The flame heats up a metal box—the heat exchanger—where room air is heated as it flows through.
Central heating systems: These systems produce heat in one central location and distribute it throughout the building. This category includes furnaces, boilers, and heat pumps. Distributed heating systems: These systems generate heat in the space they are to heat, without extensive duct systems.
That depends on the type of system installed in a building. Most HVAC systems rely primarily on electricity. However, some furnaces use gas to heat air and warm a home. For example, some systems use a separate heating unit and air conditioning unit.
While you're at the thermostat, turn it to HEAT mode and then check to see if the outdoor unit turns on. If the outdoor unit turns on, you have a heat pump instead of a standard AC unit.
Fact: Your furnace and your air conditioning system are part of your home's HVAC system. While the furnace is for heat, your AC is responsible for providing cool air for your home.
If you're wondering how to tell if the heating is gas or electric, turn it on, then look for a few clues. An electric furnace has no window or flame and shouldn't make noise. A gas-burning furnace will have a small window on the front through which you can see the main burner flame glowing blue.
If someone is at home in the daytime, 72° F (22° C) is a good start, but aim for 68° F (20° C). If everyone is away from home in the daytime or you're asleep at night, we feel 66° F (19° C) to 62° F (17° C) is best.
The two main different types of central heating systems are gas and electric options, both of which are still fairly common today.
