If you have decided to go from separate window units to a whole house system to keep your home cool, there are a number of things you should understand about your central air conditioning. This type of air conditioning is more efficient than using window units, and you will save money on cooling costs once your system is installed. Air is brought into your condenser, dehumidified and cooled, and then travels into your home through the network of ducts and supply vents.
The Condenser Is the Large Metal Unit Outside Your Home
When you have central air conditioning, the condenser looks like a large metal box that sits outside your home. There are a number of parts within the condenser, and it is responsible for converting high pressure gas from the compressor into liquid. Inside the condenser is the compressor, which is the mechanism that controls the amount of pressure within your central air conditioning unit. The condenser connects to the evaporator, which is inside your home, usually near the furnace.
The evaporator's main job is to remove heat from within the home, allowing the air conditioning system to cool down the home more efficiently.
The Expansion Valve
The fourth most important part of your central air conditioning unit is the expansion valve. This is found near the evaporator, this controls refrigerant flow into the evaporator coils. Each part of the air conditioning system is connected using copper tubing through which the refrigerant flows. This creates a closed circuit for your cooling system, and it works much like the separate window units you were using.
To get the most out of your central air conditioning system, it's important to remember that the whole system is working together to get your home cool. Remember that maintaining good air flow throughout your home is important, as closing a door can create an imbalance of cool vs. hot rooms in your home. This makes your unit work harder to cool down the warmer rooms, and you will lose system efficiency this way.
Each spring, check that there are no debris around your condenser unit. This outdoor unit brings air into it, and leaves, sticks and other debris can make the unit work harder to get the air it needs to cool down your home. You should also check your duct work to make sure there are no air leaks in it. If you are sure when your system was last maintained, call in a professional heating and air conditioning specialist to look your system over.
