There are several considerations to take into account when sizing a furnace for a home or other building:
Square footage: The size of the space that needs to be heated will impact the size of the furnace needed. A larger space will require a larger furnace to provide sufficient heat.
Climate: The climate where the building is located will also impact the size of the furnace needed. In a colder climate, a larger furnace may be necessary to maintain a comfortable temperature inside the building.
Insulation: The quality and level of insulation in the building will also affect the size of the furnace needed. A well-insulated building will require a smaller furnace to maintain a comfortable temperature.
Number of windows: The number and size of windows in the building can impact the amount of heat that is lost, which will impact the size of the furnace needed.
Number of floors: A building with multiple floors may require a larger furnace to provide sufficient heat to all levels.
When considering a new furnace, it’s important consider the sizing of the unit. Proper furnace sizing is important because an improperly sized furnace can lead to a number of problems, including:
Inefficiency: An undersized furnace will have to work harder to heat a space, leading to higher energy bills and a shorter lifespan for the furnace. An oversized furnace, on the other hand, will cycle on and off more frequently, also leading to higher energy costs and reduced efficiency.
Comfort: An improperly sized furnace may not be able to maintain a consistent, comfortable temperature in the building, leading to fluctuations in indoor temperature and discomfort for the occupants.
Safety: An oversized furnace can cause the thermostat to shut off the furnace before it has completed its heating cycle, leading to a build-up of unburnt fuel and an increased risk of carbon monoxide emissions.
Durability: A furnace that is too small or too large for the space it is heating will be subjected to increased wear and tear, leading to a shorter lifespan and the need for more frequent repairs.
Therefore, it is important to work with an experienced heating and cooling professional to determine the correct size furnace for your specific needs in order to ensure efficiency, comfort, safety, and durability.

Single-stage, two-stage, and variable-speed furnaces are different types of heating systems that operate at different levels of efficiency and have different capabilities. Here’s a brief overview of each type:
Single-stage furnace: A single-stage furnace is a basic heating system that operates at full capacity when it is turned on. It has only one setting, and it runs at maximum power until the desired temperature is reached.
Two-stage furnace: A two-stage furnace has two settings – low and high – and it adjusts its output based on the temperature inside the home. When the temperature is relatively mild, the furnace will operate at a lower capacity and use less energy. When the temperature is very cold, the furnace will switch to a higher capacity to heat the home more quickly. Two-stage furnaces are more efficient than single-stage furnaces and can help reduce energy bills.
Variable-speed furnace: A variable-speed furnace has a continuous range of output levels, and it adjusts its output based on the temperature inside the home. This allows the furnace to run at a lower capacity most of the time, using less energy and resulting in lower energy bills. Variable-speed furnaces are the most efficient type of furnace, but they are also the most expensive.
In general, two-stage and variable-speed furnaces are more expensive than single-stage furnaces, but they may save you money on energy bills in the long run. The features you choose for your home will affect the furnace installation cost, so it’s best to ask questions and understand what you’re getting for the money.
The structure of your home and existing ductwork are factors that also may need to be considered to determine if a multi-stage furnace is a good choice for your home.
It is possible to convert a gas furnace to an electric furnace, but it is typically a complex and expensive process. Here are some factors to consider if you are thinking about converting your gas furnace to electric:
Cost: Converting a gas furnace to electric can be costly, especially if you need to install new electrical wiring or circuits to accommodate the electric furnace. In addition, high-efficiency electric furnaces can be more expensive than gas furnaces.
Electrical Panel capacity: Before you can install an electric furnace, you need to make sure your home has enough electrical capacity to support it. This may require upgrading your electrical panel or installing additional circuits, which can add to the cost of the conversion.
Heating efficiency: Gas furnaces are typically more efficient than electric furnaces in producing heat per unit of energy, so converting to electric may result in higher energy bills. If you have solar or plan on having a solar array installed in the near future, this factor is less important.
We’ve compiled a list of common costs associated with conversion of a gas furnace to electric furnace below for your reference:
| Additional Costs | Cost Range |
|---|---|
| Electrical Panel Upgrade (if required) | $3,200 to $5,200 |
| Adding Electrical Subpanel (if possible) | $1,400 to $2,800 |
| 220v Circuit Installation | $600 to $2,400 |
| Capping Gas Lines | $50 to $220 |
The efficiency rating of a furnace is a measure of how much of the fuel it consumes is used to produce heat, as opposed to being wasted. The annual fuel utilization efficiency (AFUE) rating is a standard measure of furnace efficiency, and it is expressed as a percentage.
A higher AFUE rating means the furnace is more efficient and uses less fuel to produce the same amount of heat. Here are some common AFUE ratings for different types of furnaces:
In general, as the AFUE rating increases, so does the new furnace installation cost. New high efficiency furnace installations in Colorado for homes with Xcel Energy Gas & Electric accounts are eligble for $300 in rebates.
High-efficiency gas furnaces are more efficient than standard-efficiency gas furnaces, which means they use less energy to produce the same amount of heat. Here are some key differences between high-efficiency and standard-efficiency gas furnaces:
The cost of labor portion of the furnace installation cost will depend on a number of factors, including the type of furnace you are installing, the complexity of the installation, and the location of your home.
