If you are thinking of having a new central air conditioning system installed on your property, then there are quite a few things you need to consider. For example, you need to decide whether you want the outdoor condenser placed on a concrete pad, a rubber one, or on the ground. Concrete pads are often the most expensive option, but there quite a few benefits to choosing them. Keep reading to learn more.
They Remain Level
The weight of your AC condenser is the main reason why you need to secure a pad in the first place. The heaviest window units are over 200 pounds, and you can expect the bigger condensers to weigh at least this much and usually quite a bit more. The heavy nature of the units can cause them to sink into the ground, and since the copper tubing is typically located on one side of one side of the unit it will often sink unevenly.
When an AC condenser is uneven, the coolant will not flow properly through the coils or the compressor. This can lead to poor functionality, the buildup of heat, and compressor motor failure.
Keeping the unit on a concrete pad will keep it upright and level. Not only will this ensure good function, but it will keep the external coolant lines from bending or snapping.
They Elevate The Compressor
The outdoor condenser unit requires a consistent air flow, and this is often why an installation expert will suggest the placement of the unit at least a few feet from your home. Additional air flow can be acquired by elevating the unit a bit off the ground. A properly poured concrete pad can give height to the unit by at least a few inches.
When the unit is elevated, cool air flows through the side fins. This draws heat away from the coils and helps to channel it through the upper fan. This heat release is important for the overall function of the unit. If the coolant does not release heat, it will not be the right temperature for compression and movement into the indoor AC unit.
If you want the best airflow, make sure to speak with your AC installation expert about the ideal dimensions of the concrete pad. Additionally, installing your unit on the side of the home that is subjected to stronger air gusts is a wise choice.
