Major Factors To Consider When Choosing A Heating System

Are you sick and tired of your old and malfunctioning heating system? Maybe it is time to think about replacing it. Before you go shopping for a new furnace, here’s a comprehensive guide to help you choose the right system.

Energy Source Or Fuel Type

It is important to determine the energy source or fuel type of a heating system. Normally, a furnace uses natural gas or oil to operate. However, in areas where these energy sources are not available, homeowners go for electric furnaces. Seek advice from your local HVAC contractor to find out which fuels are accessible in your place and more affordable for you.


Whether it runs on natural gas or powered by electricity, the operating cost of a furnace can be substantially high during the cold season. Be sure to check the heating efficiency rating, which is measured by  AFUE (Annual Fuel Utilization Efficiency) rating for gas or oil furnaces, and HSPF (Heating Season Performance Factor) for electric heat pumps.


Size does matter when choosing your new furnace. An oversized or undersized unit can lead to skyrocketing energy bills and frequent repairs. If the system is too big, then it will short cycle often because your home heats up too quickly. On the other hand, if it is too small, the unit will work harder to meet your heating needs. To get the right size of a heating system, ask a local technician to perform a load calculation of your home.

Distribution System

Forced air units use air ducts and registers to distribute the heat throughout the house. The advantage is that the ducts can also be utilized for central air conditioning to filter and humidify the air. This system can quickly provide heat and requires little maintenance.
