Single-stage heating refers to a furnace or other heating unit that has one level for heat output, regardless of the temperature outside. This is different from some other systems that have more than one speed, and can operate on a high stage or a lower stage depending on how much heating is needed to keep your home comfortable.
Single-stage heating is when a single source and level of heat output is used to warm the entire home. The single source of heat is usually either natural gas or electricity, and it doesn’t matter what temperature it is outside – your heating unit will still be operating at the same level.
There are both pros and cons to single-stage heating. On the one hand, single-stage systems are often less expensive than multi-stage units because they don’t require multiple components or complex wiring.
On the other hand, single-stage heating can be less efficient. For example, in warmer climates, single-stage units can only operate at the same setting as a multi-stage unit on maximum output, which means higher energy bills and more noise than needed. Additionally, single-stage systems may lack the comfort and efficiency of a two stage or modulating furnace.
Two-stage and modulating furnaces are popular options that offer increased energy efficiency and comfort. A two stage system is able to provide two levels of heat output and adjust depending on the temperature outside. A modulating furnace can also adjust its heat output, but it is able to do so more gradually, resulting in improved comfort levels.
Additionally, if you want to consider a more environmentally friendly option, there are also heat pumps that use air or ground sources to provide both heating and cooling.
Ultimately, this is up to you to decide. Single-stage heating may be a good option if you’re looking for a more cost effective solution and don’t frequently experience extreme temperatures outside. However, those living in colder climates should consider investing in a multi-stage or modulating furnace for the added energy efficiency and comfort.
No matter what type of heating system you choose, make sure to talk to a qualified HVAC professional about your home’s specific needs and budget before making a final decision. With the right information in hand, you can be sure that you are choosing the best single-stage heating option for your home.

Furnaces are a whole-home heating solution that work by burning a fuel source, like natural gas or propane, to make heat. The heat produced is combined with cold air from your home, then is re-distributed via ductwork to increase indoor temperature.
Two-stage heating means your furnace functions at two levels of heating output, depending on the temperature outside.
