The Ultimate Guide to Choosing the Right Furnace for Your Home

Posted: February 13, 2023

An HVAC furnace is a critical component of any home's heating system. It is in charge of giving warmth and comfort throughout the colder seasons of the year. A furnace heats air by burning fuel, such as natural gas or propane, and then uses the ductwork to distribute the heated air throughout your house.

Choosing the ideal furnace for your house can be difficult because there are so many various types, brands, and models available. This guide's objective is to arm you with all the information you require to make a well-informed choice. From understanding the different types of furnaces available, to considering factors such as efficiency, size, and cost, this guide will provide you with the knowledge you need to choose the right furnace for your home.

Types of furnaces and their pros & cons

As we know, furnace in home are essential for heating homes in cold weather. There are four main types of furnaces: gas furnaces, electric furnaces, oil furnaces, and propane furnaces. A furnace's operating cost and way of heating the air can differ from one type to another.

Electric furnaces

Of the four types, electric furnaces are frequently the most affordable to purchase, as well as the simplest to install and operate. Despite the fact that they only require power, they can be fairly expensive to run.

In an electric furnace, the furnace draws cold air into an exchanger, where it is heated using electric heating elements. After that, ducts carry the heated air inside your home.

Although an electric furnace is more expensive to run, it has the advantage of not producing carbon monoxide, making it safer for the environment and the health of your family.

Natural gas furnaces

If you live close to a natural gas line, a natural gas furnace may be less expensive to run than an electric furnace — particularly if a natural gas line already runs to your house.

A gas furnace is more expensive to buy than an electric furnace, but it is less expensive to run because it runs on natural gas rather than electricity. Because it can swiftly heat the air inside the heat exchange chamber, it is also more potent than an electric furnace.

Oil furnaces

Natural gas and oil furnaces function mostly in the same way. When the furnace is turned on, oil is drawn from a tank and placed in a burning chamber. Instead of being lit right away, it is first made into a mist and then sprayed onto a burner. When a fire is set, air is pulled to the burner, heated there, and then redirected through the ductwork into the house.

Propane furnaces

The only difference between a propane furnace and a natural gas furnace is that a propane furnace doesn't need a flue to operate. Instead, you might merely put up a direct vent next to it on a wall that faces the outside. This does away with the requirement for routine flue inspection and cleaning.

What are the components of HVAC furnace?

The components of an HVAC furnace are essential to its proper functioning. These components work together to provide heating to a building. The main components are:

  • Blower Motor: The blower motor circulates air throughout the HVAC system. It is usually located in the air handler.
  • Burner Assembly: The burner assembly is where fuel is burned to generate heat. It consists of the fuel nozzle, igniter, and a series of burners that ignite the fuel.
  • Combustion Chamber: The combustion chamber is the area where fuel is burned and heat is generated. 
  • Control Board: The control board regulates the operation of the HVAC system. It receives signals from the thermostat and sends commands to various components, such as the blower motor and gas valve.
  • Duct Connectors: Duct connectors are used to connect different sections of ductwork together.
  • Evaporator Coil: The evaporator coil removes heat from the air inside the home. It is usually located in the air handler and consists of a series of metal fins that transfer heat to the refrigerant.
  • Pressure Switch: In a furnace, a pressure switch is a safety device that detects the presence of proper airflow, ensuring that the system operates safely by preventing the furnace from igniting if there is insufficient ventilation. Find out furnace pressure switch troubleshooting tips.
  • Filter: The filter removes dust, dirt, and other contaminants from the air before it is circulated throughout the home. 
  • Flue Pipe: The flue pipe vents combustion gasses outside the home and is designed to withstand high temperatures and pressure.
  • Gas Valve: It controls the flow of gas to the burner assembly. It opens and closes to regulate the amount of fuel that is burned and is typically controlled by the control board.
  • Heat Exchanger: It transfers heat from the combustion process to the air that is circulated throughout the home. It is usually located in the furnace and is made of metal to withstand high temperatures.
  • Circuit Breaker: The circuit breaker in a furnace serves as an electrical safety device, interrupting the power supply in case of electrical faults or overloads, preventing damage to the furnace and reducing the risk of electrical fires. Here is what to do if your furnace tripping your circuit breaker
  • Ignition System: The ignition system lights the fuel in the burner assembly. It can either be a pilot light that remains lit all the time, or a hot surface ignition that only lights when heat is needed.
  • Inducer Motor: The inducer motor pulls combustion gasses out of the furnace and vents them outside. Located near the furnace, it operates the blower that draws air through the heat exchanger.
  • Thermostat: Thermostat controls the temperature inside the home and sends signals to the control board to turn the HVAC system on and off as needed.
  • Transformer: The transformer is responsible for converting high voltage electrical power to low voltage electrical power. Located near the control board and supplies power to various components.
  • Vent Pipe: The vent pipe is responsible for venting combustion gasses outside the home.

Factors to consider when choosing an HVAC furnace

Choosing the right HVAC furnace is a crucial decision that affects the comfort and energy efficiency of your home. Here is how to choose the right furnace:

  • Type of Furnace: Furnaces come in different types including gas, electric, oil, and propane. Consider the fuel source available in your area and the cost of operating each type.
  • Size of the Furnace: A furnace that is too small or too large can result in higher energy bills and reduced comfort. It is essential to find the correct size of the furnace by considering the size of your home and the heating needs.
  • Efficiency Rating of the Furnace: Furnaces come with a Seasonal Energy Efficiency Ratio (SEER) rating that measures their energy efficiency. 
  • Insulation: The insulation in your home plays a significant role in how efficiently your furnace operates. Consider the insulation in your home and the potential for upgrades to maximize your furnace's efficiency.
  • Warranty: Furnaces come with different warranty options. Consider the length of the warranty and what it covers to ensure you have adequate protection.
  • Quality of Installer: Choose an experienced and reputable installer who will perform a professional installation and offer ongoing maintenance and support.
