Information About Heating And Air Conditioning Systems

By Melinda Kelton


There are a few different techniques used to bring heat into a home or to channel heat out of a home. The main systems are furnaces and air conditioners. Air conditioners generally use a refrigerant gas for heat absorption in the home which is then transferred outside. When looking for a trusty heating and air conditioning system, your focus should be on the energy saving features of the model that you'll purchase. You need to also keep the requirements of your house under consideration.

TRANSFERENCE

If you need a system that is efficient then a transference system is your best option. The task of such systems is to move heat as opposed to making it. This is a function that air conditioners do automatically; but, heat pumps are even better. The role of a heat pump is to take heat from outside and bring it inside in winter, and to take heat from inside the home and transfer it outside in the summer. However, heat pumps don't work as efficiently in extremely cold climates and they also have a tendency to have a higher initial cost.

GAS

Gas furnaces create their own heat through the process of burning propane or natural gas. They don't transfer heat. If there are no natural gas lines in the area, then propane is generally used. If you live in a colder climate, then in place of utilizing a heat pump there are a range of reasonable gas furnaces that you can use. Today's high-efficiency gas furnace designs are much more efficient than older models. Additionally, gas furnaces do not require as much maintenance as normal oil furnaces.

The Right Size

Heating and air conditioning systems come in a range of different sizes; they are created for buildings of different sizes. A system that's too small will over work itself which can lead to costly repair and maintenance charges. A system that's too large will most likely stop and start often, causing the same issues as a system that's too small. You should always consult a heating and air conditioning expert to work out the most beneficial size for your house.

Making the effort to investigate heating and air conditioning options can pay enormous dividends in the cost reductions to run and maintain these systems over the long term.

Great Tips For Air Conditioning Systems

By Roger Gray


Interestingly enough a big AC may not be your ideal answer to the summer heat. Know that big AC units tend to click on and off, so they may be give you less cooling than the smaller units. You're better off with smaller units that are running longer to maintain the room temperature, and it removes moisture from the room.

And even for central air-conditioning, the size of the unit is very important. You'd need a professional to take care of the sizing, though. For central air-conditioning, you have to make sure that the fan shuts off along with the compressor.

Here are some tips that will help you with your air conditioning systems.

Use whole house fans. These help maintain a cool temperature by dragging cool air through the whole house and throwing out the hot air through the attic. These fans are best used at night, when it's cooler outside.

In the summer months your thermostat should ideally be set as high as possible. You should know that the closer the temperature outside and inside, the smaller your cooling bill. When the thermostat is at a colder setting, the cooling rate will not be as fast, and the temperature will fall to an uncomfortable level, and your bills will increase.

Let your fan's speed be high, unless of course the weather is particularly humid in which case you will be better off setting it at a lower speed.

You should have an interior fan to help you window AC along. This will give your AC a helping hand and distribute the cool air better without unnecessarily increasing your electricity bills.

Putting your lamps, TV sets etc. near your thermostat is a big no-no. The heat from appliances can be detected by the thermostat, and this can cause the AC to run longer than necessary.

You can put plants near your AC, but make sure they aren't in the way of the airflow. You should be aware that an AC unit that is shaded will use 10% less electricity than one that is in direct sunlight.
