Furnaces were not always as efficient as they are today. Not only do people with older furnaces have to deal with routine repairs, but they also pay higher monthly bills. If you're like most people, you haven't even thought of replacing your furnace. The idea is to use it until it can't work anymore. You stand to gain a lot by investing in a high efficiency furnace. One of the best parts of getting a new furnace is the fact that you don't have to worry about it for decades into the future.
Not many people know when to buy a new furnace. Routine maintenance is normal for furnaces. But when you find yourself calling up HVAC companies to come out and do furnace repairs in Overland Park year after year, that should tell you something. It doesn't make sense to keep on fixing an old furnace when you could invest money in a new one that saves you money on your monthly utility bills. The older the furnace, the less efficient it is. The less efficient a furnace is, the more money it costs to run it. It is also much harder on the earth. Not only does this result in lower emissions for the environment, but this allows you to keep more money in the bank than you would otherwise.
There is a standardized rating system to help determine how effectively a furnace is running, which is categorized as an Annual Fuel Utilization Efficiency rating, or AFUE for short. Essentially, this rating is based on how much fuel a furnace eats up while it's on, and compares it to the amount of fuel that is wasted in exhaust. Old furnaces typically get rated at a 65%, meaning that 45% of the fuel that is used simply exits the flue in the form of exhaust. This means it takes more fuel to get the same result as a higher efficiency furnace would provide you.
As the years progressed, the requirements placed on furnace and heating units became more stringent. Obviously emissions take a massive toll on the atmosphere and surrounding environment. To help curb that effect, the government requires that new furnaces have a minimum rating of 78%. Luckily, you can do way better than that if you want to. If 78% sounds good, look into modern high efficiency furnaces. Their ratings can be as good as 98.2%. Only 1.8% of the fuel used by your furnace is wasted.
The less fuel your furnace uses, the less money you have to spend in utilities. People who go from an old furnace to a newer high-efficiency model, with over 90% AFUE rating see between a twenty five and thirty percent drop in their bills each month. When your furnace continually breaks down and you have to call an Overland Park HVAC company every winter, it's time to buy a new one. Save money, stay warmer, and help the environment in the meantime.
