No furnace is designed to last forever. Age and mechanical issues will one day make it necessary and more cost effective to simply replace your old furnace. Although this will require an investment, it doesn't have to break the bank if you use the following tips.
1. Shop Before Your Furnace Goes Out
Your service tech can usually give you a warning that your furnace is reaching the end of its life. As a general guideline, the typical furnace has a lifespan of less than 20 years, so if your furnace is more than 10 years old, you should likely have a replacement budget in place. Another sign you will need a new furnace soon is if it has needed more frequent repairs recently. Start shopping around and researching different furnaces long before you need to replace yours so you don't have to make a quick decision because you are rushed.
2. Replace Your Furnace in the Off Season
Another big way to save some cash is by planning to replace your furnace in the spring, after the heating season but before the AC season begins. Many HVAC technicians offer discounts at this time because business tends to slow down. This way, you can also have your new furnace installed before your old one goes out completely in the middle of winter. Even better, there likely won't be a long wait for an installation appointment since it is a slower season.
3. Look Into Local Rebates
There may be rebates offered by local utility companies or the city, particularly if you opt for a high-efficiency furnace or one with a particular fuel source. Contact these entities before choosing your furnace to inquire about any possible energy rebates that are available. In some instances, it is more cost effective to purchase a higher priced but high quality furnace with a rebate than a cheaper one without the rebate.
4. Stick to the Same Fuel Source
Changing the fuel source can make it more expensive to replace your furnace. For example, if you have an electric furnace and purchase a gas furnace to replace it, you will have to pay to have gas installed to your home or at least to have an additional gas line routed to the furnace. Often it is less expensive to stick to the same fuel source, unless your old fuel source has drastically increased in cost.
