With spring on the way, you may be considering contacting an HVAC company to replace an old and inefficient furnace. By taking care of the problem in the off-season, you can ensure the new system will be ready for use once winter returns. It can be challenging to know what to look for in a replacement, so use the following guide to help you decide.

What Type of Furnace Do You Need?

A consideration you will encounter when working with an HVAC company will be determining the type of furnace to install. Choose a replacement unit that uses the same fuel source as the old system, such as natural gas or electricity. This measure will make the installation much faster and more affordable.

You should also consider the Annual Fuel Utilization Efficiency (AFUE) rating for the furnace you are considering. This score represents the overall efficiency of the unit. For example, an AFUE of 85 indicates that 85% of the energy used by the furnace heats the home, but 15% will escape.

Appliances with an AFUE of 90 or higher are the most energy-efficient. However, lower AFUE ratings can be sufficient in areas with milder winter temperatures.

Does Furnace Size Matter?

Furnace sizing accounts for several different factors. Before installation, you need to consider the size of the building, the number of occupants and their comfort preferences, the number of windows you have, and the quality of your insulation.

A properly fitted system will operate more efficiently and be better equipped to maintain a comfortable indoor temperature. The correct sizing also reduces the risk of significant maintenance issues caused by overworking the unit. For instance, a furnace can’t heat the entire home if it’s too small.
