Air conditioning is essential for keeping your home comfortable on hot days. While there are many different types of air conditioners available, it is important to understand how they work before you select one. Air conditioning systems cool by removing heat from the air inside your house and transferring it outdoors. To do this, they use a cooling agent, usually a refrigerant. The refrigerant moves through a series of coils, which cool the air before it is vented back into your home.
There are several factors to consider when choosing an air conditioner, including your budget and whether you have ductwork. You may also want to consider energy efficiency, especially since higher efficiency ratings typically save money over time. A qualified heating and cooling expert will be able to help you determine the best options for your home.
Portable Air Conditioners
A portable air conditioner is ideal for cooling a single room, kennels or bathrooms. These units can be single hose models that blow the cooled air out the window or dual-hose units that pull in the outside air through one hose and cool the compressor with the other. Portable ACs are typically powered by electricity, though battery-powered units are available.
In order to cool a room, these units must be placed close to the area to be cooled. They are often noisy, and can cause damage to surrounding items if they are not securely anchored. They can also fall out of the window if not secured, which poses a hazard for anyone walking underneath them.
Air Conditioners for Homes
A centralized air conditioning system is the most common type of air conditioner found in homes today. This air conditioner works by regulating air throughout the entire house using a network of ducts. The conditioned air is then distributed by fans to each room in the house, where it is blown through vents. Ductless air conditioning systems are an alternative to central air conditioning for homes that don’t have existing ducts.
The cooling process is accomplished by passing air over a set of evaporator coils. The evaporator coils are saturated with a volatile liquid refrigerant, which cools the air as it passes over the coils. The cooled air is then dehumidified and circulated by the fan.
Most air conditioners today are designed with environmental concerns in mind. This includes using ozone-safe refrigerants and installing insulation to reduce air leakage. The Environmental Protection Agency (EPA) recommends that you have your air conditioner inspected and serviced annually by a qualified professional. In addition to ensuring proper operation, this will help ensure that the refrigerant is properly charged and that the air filters are clean. Keeping these filters clean can decrease operating costs and improve the longevity of the unit. It is also a good idea to make sure that the outdoor condenser unit is not located too close to trees or other obstructions, and that leaves or debris do not clog the air flow.
