Difference Between a Heat Pump and Furnace


A furnace depends on a fuel source and fan to heat most of the homes in the greater portland. The source of fuel, often natural gas, burns in the chamber, and the hot air is then forced through your channel and into your home with a fan. Because a furnace uses flames to cause heat, it blows a much warmer air as compared to a heat pump.

Furnaces are widely used as a residential heating choice in the greater Portland, according to the United States Department of Energy. However, due to winters, heat pumps are preferred choice in much of the Northeastern region of the United States.

A furnace has very few mechanical components as compared to a heat pump, meaning it rarely breaks down, requires very minimal maintenance, and has a very long lifespan on average. Furnaces are less energy-efficient when compared to heat pumps but very good for homes who use natural gas or want warmer air. Furnaces are energy-efficient over the years, but homes with a furnace also require a separate air conditioning unit to cool the houses.


  • Newer models can be up to 99% EFFICIENT in heating the homes.
  • They are best in the extreme atmosphere because they don’t depend on the outdoor temperatures to convert to heat.
  • If your winters are very cold and have temperatures always below freezing point, this is the right system for your home.


You will need a separate cooling system to beat the heat in the summer.

Heat Pump

Heat pump, unlike furnaces, a heat pump does not use fuel to generate heat. A heat pump doesn’t generate heat at all. Instead, it pulls heat from the outside and warms your home more slowly. A heat pump also works as an air conditioner to homes

Heat pumps are excellent for homeowners who live in climates that don’t experience long, cold winters, but experience a short stretch of cold weather. Other pros heat pumps have over furnaces, aside from their adaptability and use of less energy, are that they typically cost less to install.

In some cases, heat pumps are the best options for—especially in mild, dry weather—and demand for heat pumps has been on the rise. A heat pump will automatically turn on and off not quite often than a gas furnace, and most systems had gotten rid of blowing of cold air through the vents that used to occur when the system temporarily diverted into reverse to dissolve the coils.

In cold regions like the Northeastern part, heat pumps have not been the best choice. In Maine, most homes would need to add to their heat pump with an oil furnace during the winter months. So, for those homes interested in it because they are better to keep in mind that the electricity they require is completely generated by the blazing of fossil fuels, rendering them no greener as compared to a furnace in your vault. Heat pump mechanization has developed in years, but most homes can’t rely on heat pumps as their only source, but only when their homes is very well insulated.


  • It’s over-productive in temperate climates and can serve as both Air conditioner and heater
  • If your winters always average around 35-40 degrees, a heat pump is the best suited your home.


  • This system doesn’t fare well in extreme cold or heat.
  • If there’s a wide temperature differential in either direction, it will need more energy to keep the desired internal temperature.
  • Frost a times affects the outdoor compressor’s efficiency.
