Always on a really hot day! A hundred and two degrees out and all of sudden you have no cool air blowing in the house. This is a terrible situation that happens to thousands every year. Sometimes your air-conditioning unit can be repaired but many times it will have to be replaced. The selection and installation of an air-conditioner is a major project. It is important to replace your failing unit before it breaks down if possible. On the other hand, it also makes economic sense to get the greatest possible use from your old air-conditioning unit. More factors to consider in your purchase decision include the type, efficiency and functionality of your new unit. The amount of space that needs to be cooled and your choice of installer are also important for selecting a new cooling unit.
There are portable units, room units and central units. A portable unit is convenient because you can easily move it to the part of your house that most needs cooling. A traditional room unit is a cost-effective method of cooling a room, although it is only suitable for cooling small spaces. Central cooling units can cool your whole house, and many owners of these units report that they cost less to run than multiple room or portable units. A central air-conditioner also makes less noise since the indoor unit is typically installed in the attic, away from the living areas
The efficiency of an air-conditioning unit is a critical factor because it determines the unit's cost of operation. Efficient air-conditioners are more expensive, so you need to compare the initial cost of the unit against its operational cost when choosing a new unit. Central units for residential use are typically rated with the Seasonal Energy Efficiency Rating. This rating allows you to make an effective comparison of the operating costs of different units.
All systems can perform the basic role of cooling air, but many units can perform other tasks. Many modern air-conditioners have a Dehumidifier that reduces the moisture in the air as it passes through the unit. Some air-conditioners also have an electronic air filter that removes particles from the air, which can be helpful if you have allergies.
An air-conditioner capacity should be appropriate for the area it needs to cool. If an air-conditioner is too small, it may not provide sufficient cooling even if it runs continuously. An air-conditioner that is too large may cost more to operate because it is frequently turning on and off. Large air-conditioners that cycle on and off frequently may also have difficulty with removing excess moisture from the air.
The best time to purchase a new system depends on multiple factors. They are typically available from May through September, with most sales occurring in July and August. The lowest prices are usually available at the beginning and end of this period. You must also consider the climate in your area when deciding when to buy an air-conditioner. The prices for air-conditioners will typically be higher when your area has a long, hot summer.
Installs of a central unit requires a licensed professional contractor. It is important to select an installer who specializes in your particular type of installation. Businesses should especially careful to hire installers with experience in commercial air-conditioners, as these units are much larger than residential units.
