How to Choose the Right Gas Furnace for Your Home

Your Guide to buying the best Gas Furnaces

Overview

This buying guide provides detailed information on Gas Furnaces, including the different types available, the features to look for when shopping, and steps to consider when selecting the right model for your home. With the help of this guide, you can make an informed decision when purchasing a Gas Furnace, as well as determine whether it makes sense for your home’s heating needs.

Key features

  1. Fuel Type: Gas furnaces burn either natural gas or propane to heat your home. Make sure you know what type of fuel you have available before purchasing.
  2. BTU Output: The BTU output of your furnace should be sized to the heating needs of your home. Undersized furnaces are less efficient and will not adequately heat your home, while oversized furnaces run inefficiently and waste energy.
  3. Ignition Type: Furnaces are available with either a standing pilot light or electronic ignition. Electronic ignition is more efficient, as the pilot light remains off until the furnace is needed.
  4. Efficiency Rating: Look for a furnace with an Annual Fuel Utilization Efficiency (AFUE) rating of at least 80%. Higher ratings indicate greater efficiency, with the most efficient furnaces rated up to 98.5%.
  5. Warranty: Check the warranty on any gas furnace you are considering. Many brands offer longer warranties on the heat exchanger, which is the most expensive component of the furnace.

Cons

  • Cost: Gas furnaces can be expensive to purchase and install, and ongoing costs for repairs and maintenance can be significant.
  • Efficiency: While gas furnaces are more efficient than older models, they can still be less energy efficient than some more modern alternatives.
  • Pollution: Gas furnaces release carbon dioxide and other pollutants into the air, potentially causing indoor and outdoor air quality issues.
  • Safety Concerns: Improper installation and maintenance can lead to issues such as carbon monoxide poisoning and other safety hazards.
  • Noise: Gas furnaces can be quite loud when operating, making them a poor choice for quiet homes or those looking for a peaceful environment.

Best alternatives

  1. Heat Pumps - A heat pump is a device that transfers heat from one location to another. It can be used to heat your home, and it can also be used to cool it.
  2. Geothermal Systems - Geothermal systems use the energy stored in the earth to heat and cool your home. They are more efficient than gas furnaces, and can save you money in the long run.
  3. Solar Heating Systems - Solar heating systems use the energy from the sun to heat your home. They are very efficient, and can drastically reduce your energy bills.
  4. Wood Stoves - Wood stoves are a great way to heat your home. They are efficient, and can provide a cozy and inviting atmosphere.
  5. Electric Furnaces - Electric furnaces use electricity to heat your home. They are relatively inexpensive to run, and can provide a consistent source of warmth.
