Furnace Installation and Repair

Most homes and apartments have a central heating system to generate heat and ensure the comfort of the occupants. A heating system can consist of a furnace or a heat pump to transfer heat by conduction, convection, or radiation. If you need to choose the ideal heating system for your home, a skilled HVAC technician will be able to help you do just that. Here is some basic information about the heating systems we offer at Jon Wayne Heating & Air.

Types of Heating Systems

The most popular heating systems are electric heat pumps and forced air furnaces, which can be electric or gas.

  • Electric heat pumps – A heat pump can be ideal for climates with moderate heating needs. In general, electric heat pumps tend to be more energy-efficient than furnaces. A heat pump will use electricity in order to move heat to a warm space from a cool space.
  • Electric furnaces – Electric furnaces use electricity to product heat. This heat is transferred to the heat exchanger and the air from the return ducts is blown over this heat exchanger. The warmed air is then blown into the home’s ductwork to carry to the various rooms of the building.
  • Gas Furnaces – Gas furnaces will use natural gas to produce heat. The setup is similar to the electric furnace, but it carries a small risk of a carbon monoxide leak if not maintained properly.

How Are Furnace Units Rated and Categorized?

New oil, gas, and propane furnaces usually have efficiencies of 78 to 96 percent AFUE (annual fuel utilization efficiency). These furnaces usually fall into one of two or three categories.

The base model furnace, also referred to as a minimum efficiency furnace, will have an AFUE of 78 to 80 percent. Older furnaces, on the other hand, have an AFUE of 60 to 70 percent. The use of improved heat exchangers, internal vent dampers, and electronic ignition is the reason for this rise in efficiency. In more mild climates, the base model furnace is usually most cost-effective.

A mild-efficiency furnace will have an AFUE of up to 83 percent for propane or gas. An oil mild-efficiency furnace will have an AFUE of up to 87 percent. Better venting and control of combustion air is the reason for this improved energy efficiency. High-efficiency propane or gas furnaces have 90 to 96 percent AFUEs.
