Take your model number and align the digits or series of digits to the graph
. For example, a Lenox furnace with a model number G60UH24A045X would be a gas, two-stage furnace, based on the first three digits.
How do I know what kind of furnace I have?
How can you identify how old your furnace is? Your furnace
should have a sticker located anyplace on the exterior or interior paneling
. If you don't see a sticker with the model and serial number on the outside, find where the paneling opens up and see if it's located inside that door.
What is the difference between a single and 2 stage furnace?
A furnace with single-stage heating contains a fixed gas valve and a single-speed blower motor. … A model with two-stage heating contains a two-stage gas valve and a variable-speed blower motor. This allows the furnace to run at a
lower setting
in milder weather and a higher setting in very cold weather.
How do I know if I have a 1 stage or 2 stage heat pump?
A single stage-compressor only lets the
heat pump cool/heat at full blast
. A two-stage compressor allows the heat pump to cool or heat at different levels: High (full blast) and low for milder days. … Well two-stage heat pumps run more often, while using less energy.
Are all furnaces 2 stage?
80% AFUE furnaces are available in single-stage and
two-stage models only
. 90% and higher furnaces are offered in all three types. Single-stage furnaces waste energy when they run at full capacity, stop, run at full capacity and so on.
Is a 2 stage furnace worth the money?
While it is true, a
two-stage furnace costs more when it comes to purchasing and installation
, and it will save you money long term. It also reduces temperature fluctuation at the house and will heat the home and let it cool when it is less cold outside and work in a more “intelligent” way than a one-stage furnace.
What is the advantage of a 2 stage furnace?
The ability to switch between two power modes
makes two-stage furnaces more energy-efficient than their single-stage counterparts. The low power mode allows the unit to conserve energy as well as reduce temperature fluctuations and uneven heating in your home.
What are the three types of furnaces?
- Gas Furnace.
- Oil Furnace.
- Electric Furnace.
- Modulating Furnace.
What are the three types of heating systems?
- Furnaces. Furnaces are the modern evolution of that same heating technology used since the dawn of time: burning fuel to create heat. …
- Heat Pumps. The terms “heat pump” and “furnace” are often used interchangeably, but this is a mistake. …
- Boilers. …

Is a heat pump better than a furnace?
Under ideal conditions,
a heat pump can transfer 300 percent more energy than it consumes
. In contrast, a high-efficiency gas furnace is about 95 percent efficient. Heat pumps are powered by electricity, so you can save substantially on fuel consumption.
Do you need a special thermostat for a two-stage furnace?
The
thermostat only kicks in the second stage if the furnace can't maintain 6 to 8 degrees per hour
. A two-stage thermostat may need more wires than your current programmable thermostat. … If you plan to keep your home at a constant temperature, you don't need a two-stage thermostat.
What does Stage 1 and 2 mean on my thermostat?
The second stage is the full capacity of your system.
1/3 compressor capacity is the 1st stage
. 1st stage is more efficient than 2nd stage, but systems are designed to use both stages, so no worries there.
Why are staging thermostats used on heat pumps?
Why do heat pumps require a particular type of thermostat that's different from an air conditioner's? The reason is that
heat pumps must control both heating and cooling
. To switch from one to the other, the thermostat needs to signal the reversing valve to change the direction of the flow of refrigerant.
What are the worst furnaces?
- Arcoaire (2.2 average rating)
- Buderus (1.7 average Rating)
- Burnham Furnaces (1.8 average Rating)
- Ducane (2.3 average rating)
- Evcon (2.2 average rating)
- Keepright (2.4 average rating)
- Tempstar (2.5 average rating)
- Weatherking (2.4 average rating)
Which is better 1 stage or 2 stage gas furnace?
A two-stage furnace runs at 70% capacity most of the time it is heating. This gives you better efficiency. The heat cycle is longer, but more consistent. The most efficient two-stage furnaces are
95% to 97% efficient
.
How efficient is a 20 year old furnace?
The U.S. Department of Energy indicates that a 20-year-old furnace
wastes at least 22 % of the energy it consumes
. … Compare that to a new furnace whose AFUE (annual fuel utilization efficiency) rating is 95%, meaning that you only lose half a dollar for every ten dollars' worth of energy consumed by your furnace.
