How to purchase a new gas furnace

Written by: Amy Whittle

While a gas furnace is one of the most costly building appliances, it can help you save energy in the long run. Older gas furnaces can use vast amounts of energy while newer models with updated technology can save you hundreds of dollars each year.

Options to consider when buying a gas furnace

When oil costs rise, choosing a gas furnace that uses fuel as efficiently as possible should be a prime consideration. While some companies make going green a top priority, other businesses are simply attracted to the savings that environmentally-friendly appliances offer. Prices for energy efficient models might be higher than those for more traditional ones, but the useful life of the appliance makes the initial investment a good one.

Dual-fuel hybrid heating and air conditioners are a common piece of old furnace technology that has been updated. While old models were inefficient, newer ones feature a forced-air gas furnace and heat pump, making them one of the most efficient choices available.

If you’re not looking for hybrid heating and air conditioning, make sure that the system you choose meets basic Energy Star requirements. Furnaces that receive a positive rating must show proof of meeting standards set by the U.S. Environmental Protection Agency (EPA) as well as the Department of Energy (DOE).

Energy Star furnaces have annual fuel utilization efficiency ratings of 80% to 95%. These furnaces can offer up to a 15 percent improvement over traditional models.

Furnace installation and maintenance

After you choose a particular type of furnace, consider the method of installation best suited for your building. Larger buildings – or buildings that have rooms of varying temperatures – might justify having dampers installed. Using dampers to direct warm air to different rooms is one zoning technique that has gained mass appeal due to the potentially-high energy savings. Dividing a building into three different zones, for example, can reap massive rewards. Energy Star home sealing and duct sealing can further enhance the furnace's efficiency.

Before purchasing gas furnaces, buyers should be certain that the units are appropriately sized to service their buildings. Larger buildings may require one or more units, or two smaller units over a single larger unit.

Maintenance should also be considered before making a final decision. Gas furnace parts should be relatively easy to locate in the marketplace. If the unit requires a specially trained technician for warranty purposes, make sure that a technician is available in the area.

Gas furnace lifespan

Furnaces typically have a useful life of 15 to 18 years, making them one of the more important purchases for a home or office. Spending time investigating all of the options available, including researching differences between hybrid and natural gas furnaces, will ensure that the furnace chosen will service your building for years to come.
