New Furnace Options

Before you start the furnace installation process, it’s helpful to understand the different new furnace options available to you. Ultimately, the choice between these heating system types hinges on factors such as fuel availability, climate, furnace installation costs, and individual preferences.

Gas Furnace

Gas furnaces, prevalent in residential heating, operate by burning natural gas in a combustion chamber. This process efficiently converts fuel into heat for the heat exchanger, and heated air is distributed throughout the house via ducts. While a gas furnace boasts high energy efficiency and cost-effectiveness, installation challenges may arise in areas lacking access to natural gas lines. Additionally, though cleaner than some alternatives, gas furnaces still contribute to carbon emissions.

Oil Furnace

Oil furnaces, relying on heating oil as fuel, feature a pump that delivers oil to a burner, producing a high heat output. An oil furnace is an option for homes without an existing gas line to access a natural gas supply. While effective in colder climates and with a potential for a long lifespan, oil furnaces necessitate space for an oil storage tank. Maintenance costs can also be higher than alternative furnace types, requiring regular attention to ensure optimal performance.

Propane Furnace

Propane furnaces, akin to natural gas counterparts, utilize propane as a fuel source. Their versatility makes them suitable for areas lacking natural gas lines. However, propane furnaces require storage tanks, posing logistical challenges for homeowners. Operating costs can vary, impacting overall expenses associated with this heating option.

Electric Furnace

Electric furnaces generate heat through electric resistance, providing a straightforward installation process without the need for fuel storage or a gas line. While offering safety benefits by not producing carbon monoxide, electric furnaces can incur higher operating costs, especially in regions with expensive electricity. The environmental impact is contingent on the energy sources used for electricity generation in a given area.

Furnace Installation Process Step-by-Step

Furnace installation can be a complex and involved process, but with the right knowledge and preparation, it can be a smooth and successful experience. Here is a step-by-step guide to everything that happens during the installation of a new furnace so you know exactly what to expect.

1. Planning and Preparation

Before the installation process begins, it is important to properly plan and prepare for the installation by working with a licensed HVAC contractor. Make sure when considering an HVAC company to install your new HVAC system, that you get recommendations from friends and neighbors, look at reviews for companies you’re considering, and get a few quotes to make you feel confident in your choice. 

Your contractor will help you select the right size and type of furnace for your home, order equipment if needed, schedule a date to complete your furnace installation, and secure any necessary permits and inspections. They’ll help you decide whether a gas furnace, oil furnace, propane furnace, or an electric furnace would be best for your home.

2. Removing the Old Furnace

If you are replacing an existing furnace unit, the first step in the furnace installation process is to remove the old furnace unit. This may involve disconnecting the gas line and electrical connections, removing the old furnace equipment from its location, and properly disposing of it. The area is cleaned and prepped to make way for the new furnace installation if the same location will be used.

3. Installing the New Furnace

Once the old furnace has been removed, the new furnace can be installed. An HVAC technician will mount the new furnace unit to the wall or floor, connect gas supply and electrical lines, connect vent pipes, and set up the heating system. If you’re switching to a gas furnace unit, you may need gas lines run into your home. 

4. Ductwork Installation

A furnace is only as effective as the ductwork system that distributes the warm air throughout your home. Leaky, old ducts can cause a loss of heated air which can make your energy bills soar. Make sure that every part of your HVAC system works efficiently so your new system helps you save money instead of wasting it. 

If your home does not have existing ductwork or if the existing air ducts are in poor condition, it may be necessary to install a new ducting system. An HVAC installer removes old air ducts if applicable, the new duct system is installed, and then the new furnace system is connected to the supply and return plenums.

5. Final Testing and Commissioning

Once the new furnace and ductwork have been installed, it is important to conduct final testing to ensure that everything is working properly. A combustion analysis is completed to ensure that the furnace is burning fuel efficiently and safely, and the combustion components are adjusted as needed to optimize performance of a gas furnace, propane furnace, or oil furnace. We measure static pressure, airflow, and temperature rise to ensure the new unit has proper airflow and functions correctly.

Maximize the Value of Your Furnace Installation

There are several measures homeowners can take to ensure that their new furnace installation lasts as long as possible, starting prior to installation and continuing during the unit’s service life:

• Choose the right size furnace: It is important to choose the right furnace that is properly sized for your home. If the furnace is too small, it will have to work harder to heat your home, which can lead to premature wear and tear. If the furnace is too large, it will cycle on and off more frequently, which can also lead to premature wear and tear.
• Have furnace installation performed by a pro: DIY furnace installation is not recommended. It is important to follow the manufacturer’s recommendations to install a furnace; failing to follow these recommendations can void the manufacturer’s warranty and may also reduce the lifespan of the furnace. A professional furnace installer has the knowledge, experience, and tools to properly install your furnace according to the manufacturer’s recommendations.
• Properly maintain the furnace: Regular maintenance is key to ensuring that your furnace lasts as long as possible. This involves cleaning or replacing the air filter regularly and having the furnace professionally inspected and serviced on an annual basis.
• Address any issues promptly: If you notice any issues with your furnace over the years, it is important to address them promptly with professional furnace repair. Ignoring issues can lead to further damage and may shorten the lifespan of your furnace.
