On scorching summer days, your air conditioner works tirelessly to keep you cool indoors. Whether you rely on a central air system or a portable unit, knowing how to clean your air conditioner effectively is crucial. 

In this blog, we’ll discuss easy steps on how to clean the air conditioner unit, ensuring that your cooling system operates at its best. So, let’s beat the summer heat and keep a refreshing indoor environment.

Why is cleaning your air conditioner crucial?

Regularly cleaning your AC unit boosts its efficiency and promotes a healthier indoor environment. Dust, debris, and mould accumulation over time can impact performance and air quality. Consistent cleaning ensures a refreshing air and extends the lifespan of your cooling system.

How Often to Clean the Air Conditioner Unit?

 Regular air conditioner cleaning is crucial for its optimal performance and longevity. The recommended cleaning frequency depends on the type of air conditioner you have:

Window AC Units:

Before jumping to how to clean window AC units, let’s first understand how often AC cleaning is required.

  • Window air conditioners are exposed to outdoor elements, dust, and debris, making regular cleaning essential.
  • Clean your window AC unit thoroughly every 1-2 months to prevent reduced cooling efficiency and ensure it operates efficiently.

Central Air Systems:

  • For central air conditioning units, it’s advisable to have a professional inspect and clean the system at least once a year.
  • Our professional air conditioner cleaner will check coolant levels, identify and fix leaks, and clean coils to maintain the system’s efficiency and prevent potential breakdowns.

Adhering to these cleaning schedules ensures your air conditioner functions optimally, providing cool and comfortable indoor spaces.

Essential Considerations for Cleaning AC Unit

Window AC unit

Before discussing how to clean a window AC unit, it’s crucial to understand two primary areas: filters and coils.

  • Filter Maintenance

Filters play a vital role in removing dust from the air. When these filters are clogged, your AC unit works harder, consuming more energy to cool your home. It increases your energy costs and impacts the unit’s effectiveness in delivering desired results.

  • Coil Efficiency

Coils are responsible for facilitating the movement of hot and cold air. That’s why cleaning dirt and dust from your window AC unit is essential.

Central AC unit

For central air conditioning systems, we recommend choosing our professional services. We thoroughly inspect the unit, checking the ductwork and confirming efficient operation. Our professional approach ensures optimal performance and addresses complex issues in the central unit.

To keep you and your house cool, your refrigeration installation must transport heat from the inside to the outside of your home. By removing heat from the air, air conditioners circulate cold air throughout your house. An evaporator coil is used to chill the air by blowing it over a network of freezing pipes. When water has evaporated from your skin, you get a cooling sensation.

Coils are filled with a liquid known as refrigerant, which converts a liquid to gas as it absorbs heat. As soon as the refrigerant is routed to another coil outside the home, it loses its heat and returns to liquid form. So because coolant is evaporating from gas to fluid-like mist on a cold window, this outer coil is referred to as a condenser.

A pump known as a compressor transports the refrigerant between two coils and alters its pressure. This ensures that all refrigerant is evaporating or condensing in the correct coils.

The refrigerant changes from a gas state and back again, allowing the system to transport more power than the pump. The compressor’s motor is the energy source needed to do this. The complete system generates about three times as much cooling power as the compressor alone.

Keeps the System Running!

Most people can do routine maintenance, such as replacing filters, but other repairs will need the services of a professional.

It is good to clean the coils and drains at the beginning of each cooling season to remove debris and clogs. As a result, it may be necessary for a professional to come out and fix it.

Refrigeration installation charge or airflow issues may also be to blame if the system doesn’t produce as much cold air as possible. These issues may need repair.

As the typical household’s energy consumption rises, we’ve come up with some suggestions for reducing the operating and maintenance costs of a split system air conditioner:

  1. To prevent wasting electricity, keep the windows and doors closed while the system is running.
  2. In the summer, the ideal temperature for air conditioning is between 24 and 25 degrees Fahrenheit, and in the winter, between 17 and 19 degrees Fahrenheit. Running expenses will rise by roughly 10% for every degree lower in the summer.
  3. Don’t keep your system running while away from home since this wastes money and effort.
  4. Run your air conditioner only when necessary. A less expensive option is to use a fan.
  5. During the fall and winter, turn off the refrigerated air conditioning and open the windows and doors to let in the cold air.
  6. If your computer has an economy mode, choose it. It saves energy by keeping the temperature at a more moderate level under the correct settings.
  7. Close the doors to rooms that don’t need to be cooled to reduce the space you are cooling.
  8. When at all feasible, use a ceiling or portable fan. Compared to air conditioners, they are a far more cost-effective option.
  9. Central cooling systems may be used to minimise the area of your home that is being cooled at any one moment by using zoning settings.
  10. An awning, shade netting, or similar structure should be used if your air conditioner compressor unit is exposed to direct sunlight throughout the day. Make sure there is enough room for air to circulate in the device.

The Ending!

The necessity for air conditioning was first sparked by a desire to manage humidity. High indoor humidity levels might have adverse effects on one’s health and well-being. Mould and other moisture-related issues might arise if humidity levels are not adequately controlled in hot, humid conditions.

This dehumidification, which can be seen by the water that drains away, is only a by-product of modern air conditioners’ primary function of reducing temperature. They are unable to regulate the temperature and humidity on their own.

The air conditioning unit is one of the most important electrical systems in your home during the summer months. It is important to keep up with routine maintenance in order to ensure that it runs smoothly and does not break down when you need it most. If you do not stay on top of things, you may find yourself in need of air conditioner repair.

How much does an air conditioner repair cost? That depends on the system you have, the issue in question, and several other factors. This air conditioner repair cost guide will help you find detailed pricing on how much you can expect.

Air Conditioning Repair Estimate

HVAC businesses often complete an air conditioning check-up before performing air conditioning service and repair. To find the source of the issue, an air conditioning specialist may then test and examine a number of various components of your AC unit. Once this has been determined, an air conditioning repair company will be able to provide you with a more precise air conditioner repair cost in Emerald for their services. Since certain repairs are more difficult than others, the cost could be a little more.

Home AC Recharge Cost 

After fixing a leak, an AC recharge is typically performed to prevent low refrigerant levels. An air conditioner’s refrigerant charge typically costs between $170 – $800.

AC Compressor Repair and Replacement Cost 

The air conditioner compressor is the most crucial part of an air conditioner and is referred to as the “heart” of your air conditioning system. Repairing a compressor can cost between $150 to $300 while replacing a compressor might be between $1,300 – $3,500.

AC Freon Leak Repair Cost

Freon is the gas that acts as a refrigerant in your air conditioner; it is in charge of cooling heated air. Depending on how bad the leak is, fixing a freon leak might cost anywhere from $300 – $2,000.

Air Handler Replacement Cost 

A heating and cooling system’s air handler, regulates how hot or cold air is distributed throughout the space. An air handler replacement will cost between $3,000 to $5,000.

Air Conditioner Fan Coil Leak Repair Cost

The cost to replace an air conditioner’s evaporator coil starts at around $2,600, which is roughly equal to the price of the repair. Therefore, choosing a replacement rather than a repair is more feasible.

Condenser Replacement Cost

Poor maintenance results in a buildup of dust and debris, which leads to condensers failing. It may cost around $2,500 to replace your condenser coil.

AC Duct Replacement Cost 

Reduced airflow and clogged filters are indicators of a defective air conditioning duct, which can be caused by the ducts’ condition or the duct system’s age. The duct of the air conditioner repair costs around $2700, as an estimate.

AC Blower Repair Cost

The AC unit might not turn on at all if the blower breaks out. AC blower repairs typically cost between $200 – $300, while higher-end units might cost as much as $2,700 to replace.

AC Expansion Valve Repair Cost

The expansion valve converts liquid refrigerant into vapour, therefore a faulty valve may also result in underperformance from your air conditioner. Additionally, this may result in higher utility costs. Your AC expansion valve will cost between $300 to $600 to repair or replace.

Portable air cooling can be a great substitute if you live in a place where it is challenging to install ducting or a more substantial air conditioning system. These air conditioners can be an affordable solution for renters, those who move frequently, or for a smaller living area whereas other air conditioning systems need installation, a technician, or HVAC professional, and can cost thousands of dollars.

Although a portable aircon is a fantastic alternative, it is always important to weigh the pros and cons of any potential purchase. As a reputable air conditioning service in Emerald, we want to help you make the best choice, in which we have highlighted some  portable aircon pros and cons below.

Benefits of portable air conditioners

Lower Price

One of the best portable AC benefits is that it is reasonably priced. A portable air conditioner is a cost-effective alternative when compared to the cost of a central air conditioning unit and the labour required to install it.

Simple Installation

One of the benefits of portable air conditioners is that they are easy to install.. They only need an electrical outlet and a window for the intake and exhaust hoses. A set of instructions on how to put together the window hose unit is included with the air conditioner itself.

Usually Simple to Move

One of the portable AC benefits is that those who want the flexibility to utilise cooling where they need it, the majority of models allow you to wheel the unit around to where you need it. In comparison to a window unit, it is also a great deal simpler to transfer and manage. While portable units may roll from one area to another, window units often require more than one person to relocate.


Any air conditioner you purchase will produce some form of noise, regardless of the model. Even while a portable air conditioner can significantly increase the noise in a space, it is frequently just “background noise” and isn’t bothersome. It’s crucial to understand what to anticipate in terms of noise, just as with any other air conditioner. If you really must have a silent air conditioner, look for a portable air conditioner that has “quiet” listed as a feature.

 Not Energy Efficient

Even though there are many different portable aircon pros and cons,  they are not energy-efficient. Your energy costs might drastically increase if you are using a portable air conditioner as your main source of cooling. The ideal decision is to invest in a model that has a programmable thermostat if energy efficiency is a top priority for your house.

Temperature and Humidity Control

A portable air conditioner won’t do much to manage humidity and is not designed to survive days with higher temperatures. This definitely isn’t a portable AC benefit,  it does provide enough humidity relief, the air conditioner’s water pan needs to be frequently emptied to prevent leaks and water damage.

Cools Only Small Places

The cooling capacity of portable air conditioners is limited. You’ll need to purchase many units for different rooms if you want to efficiently chill a full house. The cost of the energy needed to operate those units may pile up rapidly, and the cost of the maintenance might not even be worth it. It is preferable to take a central air conditioner emerald into consideration if you’re searching for a way to chill a complete house or business space

With a split system air conditioner, you can keep your house cool and pleasant in the warmer months. In addition to being quieter, simpler to set up, and more energy-efficient, window air conditioners are also less expensive. For air conditioner installation, you need to put the cooling unit inside and the compressor and condensation unit outside, and then run pipes and an electrical wire between them.

The installation of a split system air conditioner may be done by anybody who knows plumbing and electrical work and is willing to put in the time and effort. Although each air conditioner is unique to its maker, the air conditioning service is the same.

1. Turn off the electricity supply

Please remember to switch off the electricity to your air conditioner before you begin cleaning it. It is dangerous to clean an air conditioning system while it is running. Thus it should be avoided at all costs. Locate the service panel on the external condenser or compressor to turn off the electricity. There’s usually a box for turning things off near the machine.

2. The mounting plate should be attached to the wall inside

Hold the indoor unit’s mounting plate against the wall. The horizontal and vertical levels should be checked using a group. Mark the positions of the screw holes with a pencil, then remove the plate and drill a hole in the wall for each screw. Put plastic anchors in each hole and screw the plate with tapping screws to secure the vessel.

3. AC Condenser Coils need to be cleaned

Remove the condenser unit’s side and top panels, commonly known as the grilles, and clean the condenser coils. Depending on the fastener, either a screwdriver or a nut driver may be used. Remove the side panels by unscrewing the screws and lifting them out of the device. Avoid yanking on the fan’s wires as you remove the top, which may be hefty.

Using a soft brush or a installation refrigerator coil brush, clean the exterior of the air conditioner AC coils using this method. When it comes to cleaning the coils, extreme caution should be used. Keep the delicate fins and coils free of kinks. With a “fin comb,” you can straighten the fins if they’ve been bent. Vacuum the AC condenser coils inside and out once you’ve cleaned the outside. You may use a professional air conditioning service cleaner from the inside to remove stubborn dirt and debris from the condenser coils.

4. Connect the device to the pipes and wires that run through the wall opening

Use electrical tape to join the supplied copper pipes, power cable, and drain pipe. Place the drainpipe at the bottom to guarantee that water may flow freely. Pipes and cables should be inserted via a hole in the wall and then attached to the indoor unit as instructed in the instruction manual.

●  Adding additional insulation isn’t necessary since each line is pre-insulated.

●  To guarantee that the unit functions properly, reduce the number of bends in the pipes and cables.

● Check to see that the drainage pipe is set up so that water may flow to the proper location. Your kit’s instruction booklet provides further information.

Final Thoughts!

Connect the electricity to the condenser once you’ve cleaned the central air conditioner. Turning off the thermostat in your house is the first step. Turn on the main panel’s power and the disconnect box’s electricity. Before turning on your air conditioning, make sure you have your thermostat set to the cooling setting.

You may save a lot of money in the long-term by adequately maintaining your air conditioner. Cover your refrigerated air conditioning with plastic and secure it with a rope or bungee cords in the autumn and winter to go one step further. A professional technician should be contacted as soon as possible if your air conditioner is still not functioning correctly after cleaning it out thoroughly.
