Can I Just Buy a Furnace?

While there are many projects homeowners may choose to do themselves, DIY does not extend to furnace replacements. Furnaces are one of the most expensive appliances in your home. If a furnace is not installed properly and configured to your home, there are major risks. Attempting to install a furnace yourself or hiring an inexperienced contractor includes a number of risks ranging from poor operation, failure of the furnace, and, most importantly, safety risks to your home and family.

Since furnaces are expensive and vital to the safety of your home and family, always hire an experienced and professional contractor. When you are considering furnace replacement, learning about the key features of a furnace, what to look for in a new furnace and understanding the benefits of a new furnace are great initial steps. Educating yourself before talking to a professional contractor gives you confidence and peace of mind.

What Type of Furnace Suits Your Home?

Professional installation includes matching a furnace to your home and household needs. A new furnace suits your home when it provides enough warm air to blanket every room of your home. The key features of a furnace are size, fuel source and lifespan. Consider these features about your old furnace:


Size describes both the dimensions of a furnace and heating capacity. The dimensions of your new furnace must fit into your home. Likewise, the furnace upgrade must deliver warm air throughout every room of your home. An HVAC contractor will identify the correct size to perform efficiently within your home. When matching a new furnace, technicians will examine all existing ductwork, vents, thermostats and power systems.

Fuel Source

Especially when dealing with natural gas and electricity, entrusting an experienced professional to install a furnace is a wise choice. Fuel sources include natural gas furnaces, electric furnaces, propane furnaces and oil furnaces. Advances in technology means new furnaces will be far more energy efficient than older designs. Most often the fuel source of a new furnace will match the older unit. Replacing an existing natural gas furnace with a new high-efficiency gas furnace means reduced installation costs and a quicker installation.

Age of Furnace

The average lifespan of a furnace is about 15 years. As furnaces age, repair costs mount. This may lead to an expensive cycle of constant repair bills and reduced performance. If your furnace is more than 12 years old and begins to wear down, then you should start planning for replacement options.

What to Look for in a New Furnace

Busy homeowners don’t typically keep up on the advances in furnace technology. There are two key factors to understand in a new furnace – AFUE rating and stages.


Annualized fuel utilization efficiency (AFUE) refers to how much heat is produced for every dollar of energy consumed. Higher ratings represent lower energy consumption. That is, you want the highest AFUE rating available.

Single Stage, Multistage Heat and Modulating Furnaces

Natural gas furnaces traditionally provide a single stage. There is a single flame that turns off and on throughout the day. Multistage heat features two flames providing more accurate heat for mild and colder temperatures. Modulating heat is even more precise. The size of the flame adjusts to provide steady temperatures. The best choice for your home depends on many factors.
