How does an air conditioner work?

Air conditioner works by dehumidifying, cleaning, and circulating the air which is indoors. A filter inside the air conditioner traps dust and other particles that are in the air. The air blower area of the air conditioner circulates the air via refrigeration.

Refrigeration works by absorbing the heat in the room and transferring it outdoors. The air conditioning unit itself has two units inside, the indoor unit and the condensing unit.

The indoor unit takes out the warm air and humidity. It includes a filter, an air handler as well as an evaporator coil. The air is blown through the evaporator coil.

The refrigerant inside the evaporator coil is really what assists in keeping it cold. When air travels across the evaporator coil it cools as a result of refrigerant. Humidity condenses when it comes in touch with the cold surface of the coil.

Then this dry cool air is sent back into your home to help keep it at a comfortable level. Ducts are either in the floor or ceiling.

The condensing unit sends the heat to the outdoors that was originally indoors. The exact same refrigerant that absorbed the heat indoors will then be pressurized by the compressor after which it is circulated through another coil called the condensing coil.

The condensing coil while under extreme pressure causes the refrigerant to discharge it's heat quickly and then the coil becomes hot. A fan is used to blow across the coil which then causes it to cool and then moves the heat to outdoors.

 

What in common do good central air units have?
Good units have the following in common: They are efficient using a minimal quantity of electricity to keep your electric bills down plus they provide good service for several years, they are quiet, long-lasting and require very little service.
How do I know I have the right size unit?

An air conditioner which is too small will not keep your home cool. Likewise, a system that is too big for your home will turn on and off more than necessary and waste energy and put a strain on the compressor.

Air Conditioning & Heating EXPERTS will have a look at your whole home's air cooling needs by looking at window sizes and exposure to sun and cold, floor area, insulation or absence of inside walls and ceiling. We may also check any appliances that generate heat, the direction your home is facing and just how much of your home's exterior is shaded by trees.

Which air conditioners are energy efficient?

Air conditioner manufacturers have to rate their equipment according to its energy efficiency. This rating is known as a SEER, or Seasonal Energy Efficiency Rating. The higher the SEER number, the more efficient the equipment will be.

A lot of new homes with central air also come with a standard builder's model. However, when it's time to replace the unit a property owner can go to a more energy efficient system.

High number SEER models are usually more expensive but this expense is made up by the reduction of your home's energy bills over the long term.The best setting for your air conditioning unit is "AUTO". In this way the fan only activates when the temperature requires it. If you manually use the "ON" setting then air is circulated through the air filter and due to the fact the air is constantly being circulated the temperature stays more even in the house.^The preferred setting for your air conditioning unit is "AUTO". This way the fan only switches on once the temperature requires it. If you manually use the "ON" setting then the air is circulated and filtered through the air filter and because the air is constantly being circulated the temperature stays more even in the house.

Should shrubs or flowers be planted around an outdoor unit?
Yes they may be planted no closer than 18 inches to the unit. This tends to allow room for air flow in and out of the unit.^Yes you can plant shrubs or flowers around an outside unit but they should be planted no closer than 18 inches to the unit. This will allow room for air flow in and out of the unit.
Is it necessary to change the indoor and outdoor units at the same time?
Yes they should be replaced at the same time. The air conditioning is designed to be a completely matched system. This is the reason they should be replaced at the same time.^Yes the air conditioner is made to be a completely , matched system. Therefore, when you replace one unit you should replace the other as well.
What's the difference between a split system and a package unit?
A split system utilizes indoor and outdoor components to allow for a complete home comfort system. A package unit is a self-contained unit that does not require any air handlers, external coils, or heating units.^A split system uses both indoor and outdoor components to allow for a complete home comfort system. A package unit is self-contained plus it doesn't need any air handlers, external coils, or heating units.
My air conditioning unit ices up with frost on the coil and copper tubing. What causes this?
There might be a few reasons for this happening. This is often as a result of lack of maintenance. When a unit freezes up there is a lack of airflow or a insufficient refrigerant (FREON). A regular maintenance check this can help prevent this from happening and Air Conditioning & Heating EXPERTS can help ensure all the airflow ducts are free and clear and your refrigerant (FREON) is charged up to the proper level to get the best performance.^There might be different reasons behind this happening. Most of them are because of a lack of maintenance. When an air conditioner freezes up it is because there is a lack of airflow or a deficiency of refrigerant (FREON). If you have a regular maintenance check this may prevent this from happening and Air Conditioning & Heating EXPERTS will make sure all the airflow passages are free and clear plus your refrigerant (FREON) is charged up to the proper level.~
