When Looking At Heating For Your Home Consider High Efficiency Gas Furnaces

In today's increasingly energy conscious society, one must consider the energy efficiency of every product they purchase. Whether it's your car's gas mileage or how much electricity your refrigerator uses, we've all become more aware of our energy usage.

There are two main reasons for this, and they're pretty obvious. One, inefficient energy use costs more money. It's safe to say we're all looking to lower our bills and switching to energy efficient appliances is a big step in that direction. The other reason to use high efficiency appliances is the understanding that many of our energy sources are finite. In other words, eventually we'll run out.

One of the biggest users of energy in our homes and workplaces are the heating units. Just like most other major household products, gas furnaces have become more efficient than ever before. Natural gas is an economical method for home heating and now you can find all sorts of high efficiency gas furnaces on the market.

High efficiency gas furnaces tend to cost more than conventional gas furnaces. This is for a couple reasons. They're not yet produced on the same scale as conventional furnaces so there are still cost factors to overcome which have to be passed on to the consumer. Secondly, high efficiency gas furnaces employ the latest technologies, which, as we all know, always kicks up the cost of a product. Innovation isn't free. However, keep in mind, that this is just an initial start-up cost. Sure, you may be laying down more money at the outset, but the money you'll save with a high efficiency gas furnace will soon make up the difference and even pay for itself in the end.

Investing in a high efficiency natural gas furnace is well worth it, and let's not forget the environment. An energy efficient furnace will use less fuel, which means using less natural resources, and which means releasing less greenhouse gases into our fragile atmosphere. That's a cost that can't be calculated in dollars.

These days, gas furnaces have stickers on them which gives their AFUE number. AFUE stands for Annual Fuel Utilization Efficiency. A high efficiency natural gas furnace will have a AFUE number ranging from the high 80's to the high 90's. Furnaces with AFUE's below that range are considered medium efficiency. Such furnaces cost less but will also save you less in bills.

Another thing to look for when shopping for a high efficiency natural gas furnace is an Energy Star sticker. If it has an Energy Star label, that means its AFUE rating is in the 90's.

Remember, no matter how energy efficient your furnace is, you need to maintain it properly and keep it, along with your vents clean. A dirty or poorly maintained furnace will cause a drop in efficiency and increases in cost and fuel consumption.

Air Conditioners

There are three types of air conditioning; central, split-system and portable. Both cool your home using a cold indoor coil called an evaporator. The evaporator works with a condenser and a pump to create cool airs. In order to reap the most benefits from your air conditioner you need to know the proper size you need for your home.

A room air conditioner cools rooms. The size of a room air conditioner determines how many rooms it will cool. Those drawing less than 7.5 amps of electricity can be plugged into and 15 0r 20 amps, 115-volt household circuit, but larger air conditioners needs its own 115-volt circuit. Some require as much as 230-volt circuit. In warm climates, most homes are equipped with central air conditioning that circulates cool air through a system of supply and return ducts.

A central air conditioner can be split or a packaged unit. The split-system has an outdoor metal cabinet that holds the condenser and compressor. An indoor cabinet has the evaporator in it and contains a furnace or the indoor part of a heat pump. If you already have a furnace but no air conditioner, a split-system is the best wall to install air conditioning. Packaged central air has one cabinet that holds the evaporator, condenser and compressor. The air supply and the return ducts are inside the home's exterior wall or roof and connect to the packaged air conditioner. They often include electric heating coils or natural gas eliminating the need for a separate furnace.
