The Size of the condenser and evaporator is very important. If the condenser or evaporator are too small the system cannot adequately complete the cooling process. This results in the system not being able to transfer heat out of your home efficiently. If your Air Conditioning unit is too small, it will continuously run in an attempt to keep the indoor temperature at the desired point. This results in more ware and tear on the system, and higher utility bills.
Let Bert Black Service Companies help you with selecting the appropriate size and type of unit that best suits your needs. We can evaluate your home, and ductwork to ensure that your cooling unit will work at maximum efficiency and thereby decrease the money expended on maintenance and utility bills.
Selecting a Unit
There are several styles of cooling units to pick from. Which one is right for the job is dependent on several factors.
Types of AC Units
There are several types of cooling units available. These units range in size and complexity, depending on the space or spaces they will cool.
Room Air Conditioners are intended to cool smaller spaces and do not utilize ductwork. They infuse cooled air directly into the space that will be temperature controlled. You may recognize these the most basic of the units typically called a “window unit”. Many of these smaller units can be plugged into a standard wall socket. Some larger “window” unit may require a dedicated circuit.
Central Air conditioners utilize the same ductwork as the heating system to provide cool air to multiple living spaces. The cooled air then absorbs heat from within the living space and is pulled back into the cooling unit and cooled via the process we described the What is a Cooling / Air Conditioning Unit. Central Air Conditioning Units are either a Package Unit or Split System.
Package Cooling Units have one central cabinet located on the exterior of the home. These cabinets contain the evaporator, condenser, and compressor. Air is transported to the unit via ducts that extend through the wall or ceiling, cooled and the transferred back to the indoor space the same way. These package units often have a electric or natural gas heating unit in them as well.
A Split System central air conditioning unit is composed of metal cabinet containing the condenser and compressor located outside the home. It also has a cabinet located inside the home which contains the evaporator, and in numerous models a furnace or heat pump. If your home already has a heating unit a split system may be a wise choice for a cooling unit.
As you can see the unit needed depends greatly on the size and layout of the space that is being cooled. This is why it is so important that you work with a qualified expert when shopping for a unit. Let Bert Black Service Companies help you make the best, most efficient, and most affordable suggestion for your needs. Our team of experts can not only help you pick the best system for your needs, but we can also help with customizations that further increase the function and efficiency of your system.
Size of Cooling Units
What sized unit is needed to efficiently cool a space depends on many factors, some of these are:
- Size of the space or home
- Insulation of the space or home
- How well the home’s windows are doors are sealed
- The number and type of windows
- The amount of the space or home that is exposed to the sun
- Amount of heat generated from items in the space or home
Bigger is not Necessarily better! If you install a bigger unit than is required may result in less performance than the appropriated sized unit. Units that are larger than needed may cool the space quicker, which results in more frequent cycling of the system. This adds wear and tear to the system and can result in components failing more frequently. It may also decrease the comfort of the space or home due to the temperature not remaining constant. Last The system may not be cost effective as it will most likely cost more initially and will use more energy resulting in higher utility bills.
Air Conditioning units are typically rated by the “Ton”, which is equivalent to removing 12,000 Btu of heat per hour. Determining what “Ton” unit you need is completed by a standard calculation set by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHREA). The energy-efficiency rating will of the unit will list the Btu per hour per watt of energy utilized by the system. The minimum standard Efficiency-Energy Rating standard is 8.0 Btu/hr/W with ratings above that being better.
