How Much Does a Forced Air Heating System Cost?

A forced air heating system is part of most modern homes, and if you are facing a replacement or new installation, like most, you probably have a lot of questions. In order for this type of system to function, it relies on ductwork, vents, and plenums to distribute warm air to outlets through the home. Before you start picking out your new system, however, its best to consult with a licensed contractor to get a better understanding of your homes specific size, age, and configuration to identify the best way to your heating needs.

Forced Air Factors To Consider

There are a few common factors to keep in mind when calculating your overall cost to install forced air heating. Some of these cost influencing factors include:

  • Fuel type - Most homeowners tend to stick with what is already in their home to minimize installation costs, however, this may not always be better than switching to a system that uses a different fuel.
  • Home size - If you install a furnace with capacity that is not properly matched to your homes size, you could experience unnecessary expenses or costly repair and even replacement over time.
  • BTU, AFUE, and load calculations - This is the mathematical calculations to determine how efficiently and effectively your new forced heating air system will heat your home.
  • If you are upgrading or switching to a system with different fuel requirements, you can expect your cost to install forced air heating to increase due to additional repairs or installations needed for the successful completion.

    Theres a lot that goes into factoring your total installation costs, so it is important to have an in-depth discussion with your contractor about your options and what may be the most cost-efficient solutions that can suit your homes unique forced air heating system needs.

    Size Of Forced Air Heating System

    To help better calculate the overall cost to install forced air heating, you need to calculate the square footage of your home. An average home requires between 30 and 60 BTUs per square foot to heat it up. This will also be affected by the type of climate you live in. Warmer climates may only require 30 to 35 BTUs per sq ft.

  • So, for example, a home of 2,200 sq ft in a warmer climate may require a system of between 66,000 - 77,000 BTUs. Homes in a colder climate should require 50 to 60 BTUs per sq ft, or 110,000 - 132,000 BTUs for a home of 2,200 sq ft.
  • Furnace Efficiency: Regardless of the type of furnace installation you choose, you will have to take note of the Annual Fuel Utilization Efficiency( AFUE ).
  • A mid-efficiency furnace offers between 78-84% efficiency, compared to a higher-efficiency furnace which offers as much as 95% efficiency. While a higher efficiency rating will come at a more expensive price, the federal government does energy efficiency by offering a 10% rebate for the best-performing systems.
  • Keep in mind new or remodeled homes have better insulation and will require less to heat up, so talk to a specialist in your region about your options.
