What Is a Dual Fuel Hybrid System?

The dual-fuel hybrid heating and air conditioning system combines a fuel-fired furnace with an electric heat pump. The furnace can be powered by natural gas, propane, or oil, while the heat pump transfers outside air inside and converts it to warm or cool air.

How Does This Dual System Work?

Within a dual fuel hybrid HVAC system, the heat pump works like a central air conditioner. During spring, summer, and fall, it extracts warm air from the home to keep it an ideal temperature during mild and hot seasons. Come winter, the furnace element takes over.

What Are Fuel Hybrid Heating & Cooling Systems?

Having an optimally operating heating and air conditioning system is crucial to building a pleasant and healthy home. To ease your needs, Custom Climates is here to provide you with the utmost satisfaction in terms of our dynamic equipment and services.With the goal of offering 24/7 emergency service, we provide versatile heating and cooling solutions, positioning us among the top companies in New Hampshire.

Our modern diagnostic tools allow us to quickly determine the cause of your HVAC system’s malfunctions.In this article, we are going to discuss the main points of a Hybrid heating and cooling system and how you can benefit from it.

Do your separate heating and cooling systems take up too much space? A large furnace in the basement and an obtrusive air conditioning unit outside can interfere with your home’s aesthetic. When the systems have begun to underperform, the situation is only made worse.

What if there was an energy-efficient solution to combine both systems? The dual-fuel hybrid heating and cooling system could be the answer to your HVAC problems.

What are the benefits?

Natural Gas State Water Heaters


Hybrid HVAC systems reduce greenhouse gas emissions by using a more efficient heating source when ambient temperatures are mild.



A hybrid HVAC system is manufactured to meet the heating needs of a home or building, making it a versatile solution.

Energy Savings

Energy savings

A hybrid HVAC system can switch between two heating sources depending on the outside temperature, saving energy and money by using the most favorable source for the varying situations.



The system seamlessly transfers between heating sources if one fails.



The system switches heating sources to keep the indoor temperature steady and comfortable.

Furnaces vs. heat pumps vs. dual fuel

Furnaces, heat pumps, and dual fuel systems are all used for heating purposes in residential and commercial buildings. Each system has its own upsides, and it’s important to understand how they work before deciding which one is best for your needs.


A furnace is a traditional heating appliance that generates heat by burning fuel sources like natural gas, propane, or oil. This heat then warms the air in the house, which spreads it once more throughout the house. Furnaces are up to 95% efficient, but they last more than 20 years. Although they don’t cost much to install, furnaces do require access to either natural gas, propane, or oil in order to work. 

Heat Pumps

Heat pumps work by taking heat from a source, such as the air or ground, and transferring it to a location where it is needed, such as inside a building. The heat pump contains a compressor, evaporator, and condenser, which work together to move the refrigerant fluid through the system.

During the heating mode, the refrigerant absorbs heat from the outdoor air or ground and carries it to the indoor unit. The heat is then released into the indoor air via a fan or blower. During the cooling mode, the refrigerant absorbs heat from the indoor air and releases it outside, thereby cooling the indoor space.

Dual fuel systems

Dual fuel systems, also known as hybrid HVAC systems, are programmed to switch between the two heating sources based on which is more energy-efficient at a given outdoor temperature. The furnace generates heat by burning fuel, such as natural gas or propane, and provides supplemental heating to the home.

When outdoor temperatures are mild, the heat pump is the primary heating source in a dual fuel system. The heat pump works by extracting heat from the outdoor air and transferring it to the indoor air, where it can be used for thermal release and refrigeration. When outdoor temperatures fall below a certain threshold, the heat pump loses efficiency and the furnace

becomes the primary heating source.

Is a hybrid HVAC system right for you?

If you are in the market for a new furnace, here are some things to think about:

Fuel type

Choose the most appropriate fuel type for your needs and budget (natural gas, propane, oil, or electric).


To save on energy costs, look for a furnace with a high efficiency rating.


Choose a furnace that fits the required size of your house. An oversized furnace could lead to inefficiencies and higher energy expenditures.


Take into account the furnace’s initial purchase price and future maintenance and repair expenses.


Check your home’s ventilation to see if it is adequate for the type of furnace you select.


Verify that the ductwork in your home is in good shape and is the right size for the furnace you choose.


Take the climate where you reside into account and select a furnace that can cope with the demands of your needs.

You can save money and reduce your carbon footprint by switching to the most energy-efficient heating source based on your climate. Furthermore, a hybrid heating and cooling systems keeps inside temperatures stable all year, making it an adaptable and comfortable choice for houses in a variety of climates. So, we can say that an investment in a hybrid heat pump system is money well spent.
