Is It Cheaper To Run A Split System Or Evaporative Cooling?

When the summer heat sets in, the cost of keeping your home cool quickly adds up. Many homeowners grapple with the question of which cooling system offers the most cost-effective way to beat the heat.

Let's start with some key facts:

Split System	Evap Cooling System
It works as both heating & cooling.	It only works as a cooling system.
Installation cost: Ranges $1350 to $6800	Installation cost: Ranges $3000 to $5500
Service cost: $245	Evap single story service Cost: $269
Power consumption: 500-700 Watts	Power consumption: 200-400 Watts
Environment impact: Older Units have Harmful R22 and R410a refrigerant gas and units are non recyclable	Environment impact: Modern water technology-based evaporative is the greenest technology available in Australia, learn more here.
Coverage: Mostly it covers the area where the indoor unit is installed and the fan will disperse air flow.	Coverage: Entire house based on the vent placement
Average life: 12 years	Average life: 20 years

Now, let's briefly review how each system works to understand better.

Split System Air Conditioning

• A split system consists of an indoor unit (evaporator) and an outdoor unit (condenser).

• The indoor unit cools the air and circulates it within the room.

• It uses a refrigerant cycle to remove heat and humidity.

• Provides precise temperature control.

Evaporative Cooling

• Evaporative coolers work by drawing warm air through water-saturated pads.

• The warm air is cooled as it passes through the wet pads.

• Evaporative cooling is most effective in dry, low-humidity climates.

• Now, let's compare the cost aspects of these two cooling systems.

The evaporative cooling service cost may be slightly more than split system service & repair.

Energy Efficiency

When it comes to energy efficiency, evaporative coolers have a significant advantage. They consume far less electricity compared to split-system air conditioners. Evaporative cooling operates using the natural process of evaporation, making it a more energy-efficient option, especially in areas with low humidity. In contrast, split system air conditioners require a compressor to cool the air, which consumes more power.

Initial Installation Costs

The upfront cost of a split system air conditioner is typically higher than that of an evaporative cooler. Split systems require professional installation, refrigerant lines, and sometimes ductwork modifications. Evaporative coolers are more affordable to purchase and install. However, this cost advantage can be influenced by factors such as the size of your home and the specific cooling needs.

Maintenance Costs

Evaporative coolers are generally easier and less expensive to maintain. They require regular water pad replacements and occasional pump and motor maintenance. Split system air conditioners, on the other hand, may have higher maintenance costs, including filter replacements and professional servicing.

Climate Considerations

One of the most critical factors in deciding between these systems is your local climate. Evaporative coolers are highly effective in arid and low-humidity environments. In humid regions, their efficiency decreases. Split system air conditioners, while more energy-intensive, work well in all climates and can provide precise temperature control.
