Practical Advice for Air Conditioning Installation

So, you’ve decided to get an air conditioner for your home and are looking for information on how to go about it?

No worries! We’re here to help and walk you through the process of air conditioning installation.

Let’s get started on this exciting journey of setting up your home cooling system.

How Air Conditioners Work

Air conditioners work based on a simple principle: when a liquid turns into a gas, it absorbs heat.

By using this phase conversion, air conditioners force certain chemical compounds, called refrigerants, to continuously evaporate and condense in a closed system of coils, making your home cooler.

  • Refrigerants and coils: Refrigerants possess properties that enable them to change states at relatively low temperatures. In an air conditioner, the refrigerants evaporate and condense within a set of coils called evaporator and condenser coils.
  • Cooling the air indoors: An air conditioner pulls in warm air from your home, and this warm air blows over the cold evaporator coils. As the refrigerant in these coils absorbs heat from the air, it turns into a low-pressure gas.
  • Compressing and condensing: The warm refrigerant then moves through a compressor, which pressurises the refrigerant, making it hot. The hot refrigerant flows into the condenser coils, where it cools down, releasing its heat and returning to a high-pressure liquid state.
  • External fans and heat dissipation: Outside the unit, a second fan blows air over the condenser coils, cooling them down faster. As the refrigerant cools down, it flows back towards the evaporator, starting the cycle once again. The air inside your home gradually becomes cooler with each cycle.
  • The role of the thermostat: A thermostat is a key component, continuously monitoring the room temperature. If the room temperature rises above the thermostat setting, the air conditioner kicks in. Conversely, if the room reaches the designated temperature, the air conditioner switches off, helping to maintain the desired comfort level.

In conclusion, air conditioners are an intricate system of scientific principles and engineering marvels working tirelessly to ensure you enjoy a pleasantly cool atmosphere indoors.

Understanding the Elements – Indoor and Outdoor Units

Every air conditioning system comprises two vital parts: the indoor unit and the outdoor unit. In split systems, you’ll find multiple indoor units connected to merely one outdoor unit.

Indoor Unit

The only one outdoor unit, otherwise known as the air-handler or evaporator unit, is the part of the air conditioner that’s installed inside your home. This component plays an essential role in circulating the cooled air throughout the space.

The indoor unit is made up of four primary components:

  • Evaporator coil: This component houses the refrigerant, which absorbs heat from the warm air as it passes over the coil. The chilled air is then blown back through the room, creating a cooler atmosphere.
  • Blower: A fan, also known as the blower, helps draw the warm air across the evaporator coil and then distributes the cold air once the heat has been absorbed.
  • Filter: The air filter removes dust, dirt, and other debris from the incoming air, maintaining optimal air quality and preventing any blockages in the system.
  • Drain pan: As the evaporator coil cools the air, condensation forms on the coil. This liquid is collected in the drain pan and then expelled through a draining system to prevent any water damage or excess moisture buildup.

Outdoor Unit

The outdoor unit, or the condensing unit, is located outside your home and houses the heavy-duty components responsible for the actual cooling process. The main components of the outdoor unit include:

  • Compressor: This is the heart of the air conditioner. The compressor pressurises the low-pressure, warm refrigerant gas, turning it into a high-pressure, hot gas.
  • Condenser coil: The hot, high-pressure refrigerant gas flows through the condenser coil, where it transfers heat to the outdoor air, causing the refrigerant to cool down and become a liquid again under high pressure.
  • Fan: The outdoor fan helps to dissipate the heat absorbed by the refrigerant as it passes through the condenser coil. The more efficiently it can remove this heat, the better the air conditioning system will work overall.

The indoor unit is responsible for absorbing heat from your home and distributing cool air, while the outdoor unit is responsible for the actual cooling process and expelling heat outside. Both units work together to create a comfortable, cool environment for you to enjoy.

How to Shop for an Air Conditioner

Here are some factors to consider when looking for the best air conditioning unit for your home.

  • How Big, How Small?

There’s an ocean of air conditioning systems available in the market today – from split systems and ducted systems to wall-mounted split systems and reverse cycle air conditioners.

Each air conditioner unit accommodates different needs, and choosing the right one largely depends on the size of your house and the specific rooms you’re looking to cool or heat.

For instance, if you’re only looking to cool a single room, like your living room or bedroom, a split system air conditioner or a reverse cycle air conditioner are solid choices. In contrast, if you want to cool multiple rooms or your entire house, a ducted air conditioning system may be a better bet.

Provided you’re keen on energy efficiency, split system air conditioners are an excellent choice, known for lower running costs and overall reduced energy consumption.

  • Location, Location, Location

Thinking: “Where’s the best place to install an air conditioner?” Well, your indoor unit must be installed at a desirable location within a room where cool air can evenly circulate. Your professional air conditioning expert can assist with this, considering room layout, windows, and heat sources.

Similarly, the outdoor unit of your split system should be placed in a spot where there is ample airflow and shade. The outdoor unit must be reachable for maintenance and service while being out of reach of children or pets.

  • Energy Efficiency

The energy efficiency of an air conditioner is a crucial factor to consider. Look for air conditioning units with a high Energy Efficiency Rating (EER). Units with a higher EER will consume less electricity to cool the same amount of space, saving you money on your energy bills.

Many air conditioners also come with in-built energy-saving modes. It’s recommended to look for such features if you plan to use your air conditioner frequently.

  • Noise Levels

Always consider noise levels when choosing an air conditioner. While many modern systems offer quiet operation, some models and brands may be noticeably louder than others. Check the decibel level of the unit, usually found on the product specifications.

A lower decibel level means a quieter operation which can help in maintaining a peaceful environment, especially important if the air conditioner is for a bedroom or study.

  • Budget

Budget undoubtedly plays an integral role when shopping for an air conditioner. High-quality air conditioners can be an investment. However, opting for a cheaper unit can sometimes mean higher running costs, less efficiency, and potentially a shorter lifespan.

It’s critical to balance upfront costs with ongoing costs and efficiency. Consider how often you’ll use the system, energy efficiency, and how much you’re willing to spend on maintenance and potential repairs.

  • After Sale Support & Warranty

The quality of after-sales service and the warranty offered by the manufacturer are also essential factors to consider. Ensure the company offers a competitive warranty and has a reputation for honourable service.

Moreover, look for air conditioner models that have service centres near your location for easy maintenance and repairs.

Choosing the best air conditioner for your home involves taking into account various factors. By considering size, location, energy efficiency, noise levels, budget, and after-sales support, you can find a unit that perfectly suits your needs and provides you with an ideal indoor climate.
