7 Vital Questions About Split System Air Conditioners Answered

Despite the range of cooling machines that we have, our choice would always be a device that’s easy to install, less power demanding, generates less noise, is eco-friendly, and affordable. Ducted ACs satiating these needs is a far cry. This was why their ductless peers were invented.

Here are the answers to some important questions about these machines.

Q #1: What is a ductless split AC and how does it work?

A: As the name suggests, it is devoid of ducts. And then, it’s split into two parts – an indoor unit that contains a blower, and an outdoor unit with a condenser. Because the device comes in parts, the noise during operation is cut off (remember, the outdoor unit is placed outside the home).

A conduit connects the two units; it comprises of a power cable, and a tubing each for the refrigerant, suction, and condensate. The refrigerant is circulated within the blower and condenser. It captures the heat from within a space and lets it escape outside.

Q #2: What makes it easy to install?

A: Because they lack ducts, their installation takes minimum effort and time. However, positively do not attempt a DIY. Instead, call for professionals. They are qualified to understand how the process should be carried out. If you are a first timer, you’ll have a difficult time figuring out the same.

Only a professional can ascertain the best place for installation. He must drill a hole not larger than 3 inches, through which the conduit will pass. Also, allow him to decide the right size. Systems that are too large, often lead to energy wastage; systems that are too small can cause inefficient cooling.

Q #3: When should the device be installed?

A: This AC is suitable for residential as well as commercial usage. A split system air conditioner in Melbourne is most recommended if:

  • You are renovating your house.
  • You want to add a sunroom to your existing residence.
  • You want to keep your garage cool.
  • You want to cool a space zone-wise.

Q #4: How is it different from (and advantageous over) window ACs?

A: Both the devices serve the same purpose. However, when you have a split AC, you can have a single outdoor unit handling multiple indoor units. Technically speaking, you can install the device in up to 4 rooms using just one outdoor unit. Also, they are more energy efficient than Window ACs.

Q #5: How to install it right?


Provide sufficient space. The outdoor unit with the condenser should have a clearance space of 2 feet all around it. This is required so that air circulates and the heat escapes properly.

  • Avoid refrigerant overdose. There’s no use jamming in more gas than what’s required. The amount is precise and this is what’s recommended. Or else, you will cause improper cooling.
  • Say no to long conduits. The length of the refrigerant tubing should not be more than 50 feet. The longer it is, the more time will be required by the refrigerant to complete the cooling cycle. This will make the condenser run for a long time, which is never good.

Q #6: What are the maintenance requirements?

A: Keep the air filters and blowers clean. If there are charcoal filters, make sure you dust them often and expose them to bright sunlight twice a year for a minimum of 8 hours. These filters will not last for more than 2 years.

Have them replaced when the time comes. If your machine has Catechin filters in it, these should be cleaned regularly and replaced after two years. Also, make sure to clean the condenser coil in the outdoor unit. It is very likely that the coil will gather dust, debris, and leaves over the time. Use a soft brush while cleaning it.

Keep checking the line-set insulation from time to time, especially during summers. This is moisture laden and often, rodents arrive here in search of water. In case the insulation is damaged, it should be replaced at the earliest.

Q #7: How much should the AC cost?

A: There are a number of factors determining the cost of a split AC. They include:

  • SEER – the Seasonal Energy Efficiency Ratio. This rating should be 13 or higher.
  • Size of the cooling system. The larger, the costlier.
  • Number of blower units.
  • Refrigerant type. R410A is recommended as it is ozone-friendly and helps in quiet operations.
  • Low decibel rating. A rating of 68 is the best, quietest, and the costliest.
  • Brand value.
  • Contractor charges.

Overall, splits ACs are 30% costlier than central ACs excluding ductwork. They cost twice the price of window units. But, you should think about the bigger picture. They cut on power bills, don’t they? Moreover, they are more durable than the rest.
