Why It Pays to Buy a New Furnace, Plus Tips on How to Do It

Why Buy a New Gas Furnace

An efficient, modern furnace generates fewer emissions and uses less gas than an old inefficient model. Installing a new gas furnace can cut your energy costs and improve your comfort--but only if you get the right furnace for your needs.

Why Size Matters When Buying a New Furnace

Your first step toward getting the best new furnace for you is to choose a reputable contractor. Contact a number of contractors to ask for cost and sizing estimates. Any contractor you choose should use an industry standard load calculation to determine your heating needs, taking into account factors such as the size and demand of your home, the level of demand on the furnace, and the climate. If your furnace is too small, it won't provide enough heat for your home. If it is too large, energy is wasted through turning on and off too frequently, which can also cause components to wear out more quickly and can lead to uncomfortable variations in temperature.

Other Factors to Consider When Buying a New Furnace

• Don't buy on price alone--the cost of furnaces generally rises in line with their fuel efficiency, so paying out at the beginning could save money in the long term. Your contractor should be able to provide you with an estimate of the annual operating cost for a range of furnaces.
• Your contractor should provide you with a purchase agreement, warranty, and registration form for your furnace so you know exactly how much the total job will cost, including taxes, and what kind of follow-up you can expect if you have a problem.
• Correct installation and regular furnace maintenance in accordance with the manufacturer's instructions is important, so make sure you use a reputable contractor and schedule regular maintenance checks.

Following these tips can help you get the furnace that best meets your needs.
