Special Feature Options On New Furnaces

Modern furnaces come with many different special features that homeowners should be aware of when purchasing a new furnace. Special furnace features could allow you to make your home more comfortable or your heating system more efficient during the coldest times of the year. 

If you're on the market for a new furnace, consider models with the following options if these features sound like they might be useful additions to your home's HVAC system:

Upgraded air filtration

If clean interior air is an important concern for you, you should look at furnace models with upgraded air filtration. A furnace with such a special feature is especially useful in homes where residents suffer from allergies or respiratory issues. 

Variable-heat output

Variable-heat output is also sometimes referred to as "two stage heating." This is a special furnace feature that allows the furnace to run at lower speeds to conserve energy when possible. A furnace with variable-heat output will provide continuous heat, but it will adjust its speed to the situation rather than running at one constant speed regardless of temperature conditions. 

Variable-speed blower

Like variable-heat output, variable-speed blowers are features that improve the efficiency of a furnace. They run at two different speeds depending on usage demands on the furnace. A variable-speed blower will reduce noise and drafts in furnace operation and offer a low force air flow if the heater does not need to run at maximum strength. 

An ignition system

Furnaces that are powered by either propane or natural gas can be built with an electronic ignition instead of a pilot light.

A pilot light will steadily burn and constantly consume the same amount of fuel. On the other hand, an electronic ignition does away with this need to constantly burn fuel by getting the system started up without continuing to consume energy afterwards.

A dual-heat exchanger

Every furnace has a heat exchange. A furnace with a dual-heat exchanger has an extra exchanger that allows the furnace to collect a larger amount of heat from the burner. 

Zoned heating

A traditional furnace will heat every room in the home to the same temperature. However, some rooms are inevitably left empty at times. This means that energy is wasted heating empty rooms with a traditional system. 

A zoned heating system can heat different room of a home to different temperatures by relying on multiple thermostats. In a zoned system, airflow is controlled throughout the house to maximize efficiency and minimize waste.
