A new furnace is a significant investment for most homeowners. Cochran Cooling & Heating wants to help you make the right decision for your home and your budget. Here are some of the most important factors to consider before making your purchase.


Measured as an AFUE (the Annual Fuel Utilization Efficiency) rating, furnace efficiency is a measurement of how much of the energy put into a furnace is converted into usable heat for your home. For example, furnaces with an 80% AFUE (the minimum rating in order to comply with regulations) will convert 80% of the electricity, natural gas, oil, or propane used to power your furnace into usable heat. Higher AFUE rated furnaces may cost more upfront, but they are better for the environment, operate more quietly, and will result in lower utility bills.

System Type

Heating systems are available as either split or packaged systems. Most central heating systems are split systems with a condenser, a furnace, and a coil that sits on top of the furnace. Packaged systems consist of all the components in one indoor unit, a necessary choice if you do not have a basement, crawl space, or attic.

Fuel Source

Natural gas furnaces cost more initially when compared to electric furnaces but natural gas is more affordable in the long run. Oil and propane furnaces require more room for storage, pollute your indoor air more than a natural gas furnace, and (depending on oil prices) can be significantly more expensive to operate. However, this type of furnace might be a necessary choice for you if your home doesn’t have access to a gas line. Electric furnaces are more efficient than natural gas, oil, or propane furnaces, but they must create original heat from electricity, making them more expensive to run.


A standard or fixed-speed blower simply turns on and off but a variable-speed blower can change the speed of air distribution throughout your home, saving energy and keeping the temperature more constant.


Choosing a system that is too small or too large will result in a home that is never heated properly and unit that will likely always be running and burn out sooner than expected. A professional HVAC technician can help you determine the correct size of furnace for your home by performing a physical inspection and making a Manual J load calculation. This calculation takes your entire home into account such as square footage, insulation, heat loss, and air flow.
