All air conditioning systems work along the same lines: air is drawn into them through a filter, this air is then either heated or cooled by different procedures then blown into the rooms that have air ducts. This creates an atmosphere that is full of fresh, clean air that is temperature controlled for the comfort of those using the air conditioner. Any old stale air is then blown outside the building so that the inhabitants do not have to breathe it.

If you want your furnace to provide you with hot air then you need to make sure that the air furnace filter within the unit is changed regularly to maintain its efficiency. Many people think that air furnace filters have a longer life than they actually do and when their air conditioner isn't working as it should do blame the system, not the air furnace filter. On average every air furnace filter should be changed every 2-3 months, depending on their usage - the more a system is used the faster the air furnace filters will need replacing.

To give you an idea of the importance of changing your air furnace filter every 2-3 months here are some of the benefits:

-An air conditioner that will be running to its maximum efficiency. This will mean that not only will you be able to maintain the temperature that you want inside a building but you will not be running your air conditioner needlessly. For example if you have air furnace filters that are dirty or even blocked your furnace will have to work harder to create warm air and this will use more electricity and therefore cost you money in the long term. If the furnace air filters are very dirty and totally blocked they will not heat the air at all and will be running and costing money for no output.

-Changing furnace air filters means that the air that is heated and blown into the building is clean and fresh. If you suffer from allergies it is a very good idea to use a HEPA furnace air filter to further increase the air quality indoors. HEPA filters are the very best filter if you are looking eliminate up to 99.9% of airborne particles.

-You will save money. If you are running your air conditioner to maximum efficiency you are reducing energy wastage which will reduce your electricity bill. Obviously the amount you save will depend on the size of the air conditioning unit and the amount of usage, but you will notice a difference.

It doesn't matter if your air conditioning system is in a residential or commercial building as it is just as important to change the air furnace filter for best results.
