Surviving the 40°C Peak: Why Split Air Conditioning Helps

Thu, 12 Mar 2026 13:40:18 GMT

When a brutal summer hits and mercury soars above 40°C, households and businesses quickly rely on their split air conditioning to keep cool. Air Comfort sees it every year: sweltering temperatures send everyone rushing to crank their units to 18°C, hoping for instant relief. But, ironically, this common habit can leave you sweating, literally, with the all-too-familiar “icing up” drama as your split air conditioning in Crows Nest, NSW, freezes solid just when you need it most.

Whether you are renting a studio or own a peaceful townhouse, you may have noticed your split air conditioning starting to lose its punch right in the middle of a heatwave. Why does this happen? The answer lies in a phenomenon technicians call the “freeze-thaw paradox”.

Here’s the gist: when you set your split air conditioning system to 18°C and leave it running flat out during extreme heat, the indoor evaporator coils can get so cold that condensation on them freezes. Any airflow restriction, whether from a dirty filter, obstructed vents, or just the sheer effort of keeping up with the outside temperature, causes that cold air to linger too long on the evaporator. The result? Frost builds up and blocks the airflow, further cooling the coil and causing even more freezing.

It’s a vicious cycle. Instead of circulating a steady stream of cool air, your system ends up “icing up”, struggling inefficiently, and eventually shutting down as a block of ice traps the coil.

So what do you do when your air conditioner freezes at the worst possible time? Local residents who call Air Comfort often report a noticeable drop in blowing power or visible ice forming along the inside panel. The temptation is to turn the unit off and panic, but there’s a smarter approach.

First, switch your split air conditioning over to ‘Fan Only’ mode. This circulates room-temperature air over the frozen coil, gently thawing it out without causing water leaks or damage. Leave it running this way for at least two hours, or longer if possible. Resist the urge to go straight back to cooling mode to speed things up; slow, thorough thawing is key.

Once the airflow returns to normal and any condensation has drained away, reset the temperature, not to 18°C, but to a sensible 24°C. The difference in comfort is surprisingly small, but this allows your system to run efficiently without the risk of refreezing, especially during a Crows Nest, NSW, scorcher.

Many Crows Nest, NSW, residents live in compact apartments, where airflow dynamics are even more critical. Tiny stairwells, internal doors, and tight window spaces can drastically restrict the amount of air passing through your split air conditioning unit. When the system can’t “breathe”, it is much more likely to freeze up.

There’s a simple preventative solution: every Air Comfort technician recommends a mid-heatwave filter rinse. Pop open the front panel of your split system, gently remove the dust filter, and give it a quick rinse under the shower or tap. Let it dry completely in the shade, then pop it back in. You’ll be amazed how much extra power and efficiency this adds. Plus, your room will stay fresher and allergy-free.

Blocked filters are the number one reason for frozen coils in Crows Nest, NSW, units. Even if you’re renting and not due for a professional air conditioning service, this five-minute trick could save your summer and your cooling bill.

Your split air conditioning usually gives a warning before it ices up completely. Is it suddenly blowing out warm air instead of icy relief? Does your remote seem sluggish, or does the system start and stop randomly? Ice forming on the pipes or the indoor unit is another clear indicator.

If you notice any of these, act fast. Switching to ‘Fan Only’, rinsing your filter, and shutting internal doors to keep cool air in the spaces you need it most can often forestall a complete system shutdown. Keeping ceiling fans on low helps too, distributing cool air evenly and preventing hot spots near the ceiling.

Some problems go beyond a DIY fix. If you’ve tried all the above and your split air conditioning system still freezes, makes strange noises, or leaks water while running, it’s best to book a professional air conditioning service. Long-term neglect can lead to compressor failure, gas leaks, and expensive component replacements.

Air Comfort’s skilled team operates locally in Crows Nest, NSW, with rapid turnaround and same-day support where possible. Our experts have seen every brand, model, and setup, so you can count on quick diagnosis and honest solutions without the drama.

In 40°C heat, a clear strategy beats sheer power every time. Remember: split air conditioning works best when set sensibly around 24°C, with regular filter attention and awareness of airflow blockages. Avoid those tempting all-night “cold blasts” (you don’t want to wake up to a frozen system at dawn), and don’t forget to treat your air conditioner to a yearly professional check-up. Besides prolonging its life and keeping power costs down, annual maintenance can catch hidden issues before they become an urgent call-out.

Ice on the air con this summer? You’re not alone. When it comes to split air conditioning in Crows Nest, NSW, Air Comfort is ready to help keep your cool intact!

Reasons to Upgrade Your HVAC Unit

Mon, 21 Nov 2022 19:43:42 GMT

Air conditioning systems are essential in improving air quality in both commercial and residential buildings. Air conditioners require proper maintenance to extend their useful lives like all equipment. However, you may need an upgrade once your current AC becomes defective.

So, how do you justify the cost of a new air conditioning system? The upgrade can save you a substantial amount of money in repairs and energy bills. New equipment is also safer, especially in hospitals where air quality is a concern. A new purchase is a worthy investment, and the upgrade is sometimes impossible to avoid.

This piece discusses a few reasons to buy a new air conditioning system.

Technological upgrade

You could upgrade your commercial or residential AC system to take advantage of new technologies. For instance, if you have a traditional central AC system, you could upgrade or a split AC system. Split AC systems have cooling and heating cycles. As such, you do not need heaters to warm the rooms during the cold season.

Other technologies to take advantage of include:

Reduced noise levels if your old AC unit produces too much noise
A thermostat to help you regulate the internal temperatures
Smartphone compatibility that allows you to adjust the AC settings remotely
Dehumidifiers to help prevent moisture build-up in your home or office
AC systems that integrate water heating systems

Such upgrades can help improve the comfort of your property. For example, if you own rental property, you can attract more tenants after the upgrade since the equipment is highly efficient and reliable. A modern AC system is also a sure way to improve the resale value of your property.

Energy efficiency

New equipment consumes less energy than machines whose parts are older and weaker. In addition, new AC systems incorporate modern technologies that improve the system's energy efficiency. The heat pump is more energy efficient and is a significant upgrade.

Moreover, some modern AC systems use solar energy. These systems can help reduce the carbon footprint of your home or business. Other systems have sensors that automatically shut off the AC at specific times or temperatures. Such technologies help reduce the system's energy consumption.

The main concern about energy consumption is how much you end up paying for utilities. For example, small energy savings can help you cut down on the cost of electricity for a large commercial building. Such an upgrade can save you a lot of money in the long run.

Home renovations

Home renovations are essential in improving the house's value and making it more liveable. Such upgrades present a new challenge for your air conditioning system. For instance, you might want to remove ductwork to improve the interior appeal and make the property more spacious. In this case, you need to replace your old HVAC unit with a ductless system.

Alternatively, you may create an extension to accommodate lifestyle changes. In this case, the air conditioning system must overwork to heat or cool the property evenly. The best approach when performing such upgrades is to calculate whether the current air conditioner can handle the additional space.

It would help if you accommodated the changes in volume and the cubic foot per meter of the air conditioner. Alternatively, you can ask the installer to recommend whether you need a new air conditioner after the home renovation project.

Your air conditioner requires a total upgrade in some unavoidable situations. At Air Comfort Co of Australia Pty Ltd, we can assist you in selecting and installing new air conditioners for residential and commercial properties. Contact us today to get a free quote.

3 Parts of Your Air Conditioning System You Can't Afford to Ignore

Fri, 05 Aug 2022 17:35:16 GMT

Your air conditioner will only last long if you take good care of your unit. But some parts of your AC are more important than others since they have a greater impact on your unit's overall performance. A small issue with any of these parts can cause your energy bills to skyrocket or, even worse, lead to a complete breakdown of your unit.

So if you want your air conditioner to last for years, pay close attention to the following parts.

The compressor

The compressor is the heart of your air conditioner. This part compresses refrigerant gases and circulates them throughout the unit. As the refrigerant circulates, the fluid absorbs heat from the air inside the home and transports this hot air outside. This operational mechanism is what cools your home.

To compress the refrigerant, the compressor must have a strong motor. The motor is one of the components that use the most energy since it constantly runs when you turn on the air conditioner. As a result, a malfunctioning motor can cause your energy bills to skyrocket. Your air conditioner will have to work harder to compensate for the inefficiency.

If you notice that your energy bills are constantly going up (even when you haven't changed your AC usage), you probably have a malfunctioning compressor. The compressor is usually located near the front of the AC for most units, where an expert can easily access this part for maintenance and repairs. Call a professional immediately if you notice any issues.

Evaporator and condenser coils

While the compressor is a vital part of your air conditioner, the component cannot function without the evaporator and condenser coils. The evaporator coils must be in good working order to absorb heat from the air. You're likely to find these coils inside the air handler, a large metal box that houses the blower fan.

The condenser coils are located outside the air handler. These coils release the heat that the refrigerant absorbs. However, these coils are very delicate and can easily sustain damage. For this reason, you need to clean them regularly to remove any dirt or debris that could obstruct airflow and cause the coils to overheat.

While you can clean these coils yourself, you should leave this task to a professional. They will have the proper tools and cleaning solutions to do the job quickly and efficiently. The wrong technique or cleaning solution can damage the coils beyond repair.

Refrigerant lines

The refrigerant is the lifeblood of your air conditioner. This substance circulates through the evaporator coils to absorb heat. The refrigerant also passes through the condenser coils to release the heat absorbed from the inside of your home. The refrigerant lines carry the refrigerant between the evaporator coils and the condenser coils to allow for the proper functioning of your unit.

A leak can occur anywhere in the line, but you're likely to find one at the connection point between the coils. If there is a leak in one of these lines, the refrigerant escapes through these open points. This issue can lead to a complete breakdown of your air conditioner since there won't be efficient heat transfer.

Refrigerant leaks are also quite dangerous and can cause serious health problems if anyone inhales or touches the refrigerant. The fluid is also very corrosive and can eat through metal contact points in the AC.

So if you notice any strange fluid around your air conditioner, call a professional right away. They can properly repair the leak and recharge your air conditioner with more refrigerant. You shouldn't try to repair the leak yourself since you could cause more damage or put yourself in danger.

Many AC problems are easy to prevent with proper maintenance. With regular tune-ups, you extend the lifespan of your air conditioner and avoid costly repairs.

During a tune-up, our technicians at Air Comfort Co of Australia Pty Ltd will clean the evaporator and condenser coils, check for refrigerant leaks and inspect the air handler. This way, we can help you catch and repair any potential problems before they cause your unit to break down. Contact us today to learn more.

Considerations When Buying a Residential Air Conditioning System

websitebuilder@thryv.com — Fri, 06 May 2022 15:25:28 GMT

An air conditioning system helps you control the internal climate of your home. Most people purchase homes with AC systems. However, you could buy a home without an AC system or one that needs a new AC system. Discover what to consider when purchasing a residential AC system.

1. Type

Various types of residential AC systems are available. The secret is to examine your cooling and heating needs and the design of your home to establish which AC system suits your needs. A central air conditioning system uses a series of ducts running from an external compressor to the various rooms in your home. The advantage of a central AC system is that it cools the entire house at once.

If your home does not have AC ducts, consider purchasing a ductless mini-split air conditioning system. The system uses pipes to connect air blowers to an external compressor. Unlike the central AC system, the ductless system allows you to cool each room separately. Therefore, it is more energy-efficient.

2. Size

When buying a residential AC unit, the rule is to ensure that the system is neither too large nor too small. Most people might opt to buy a large system since they presume it is more efficient. However, this approach does not work. Besides consuming a lot of power, a large system has shorter running cycles and will therefore not extract efficient moisture from the room. Consequently, you end up having a cool, humid room.

3. Efficiency

The AC system runs for long hours every day. Consequently, it could consume a lot of power. When buying the AC system, examine its efficiency by checking the star rating system on the packaging. Alternatively, you could check the system's Seasonal Energy Efficiency Ratio (SEER).

You could also assess whether the AC system has energy-saving features such as large coils, a variable speed blower, an automatic delay fan switch and a filter indicator light.

4. Features

Discover what features your AC does or doesn’t have with these tips:

Examine the noise levels of the AC system. A noisy system could be a nuisance in your home or neighbourhood.
Consider smart AC systems. These systems are smartphone-compatible, meaning you can control the system from anywhere on the planet.
Access the refrigerant the AC system uses. Preferably, consider systems that use environmentally friendly refrigerants.
Consider AC systems with a programmable thermostat that enables you to adjust the AC temperatures.

5. Durability

Given that you will spend a significant amount purchasing and installing the AC system, evaluate its durability.

Online reviews can give critical insights into the reliability and durability of the AC system. For example, they inform you whether the AC develops problems such as electric control failure, damaged thermostats, sensor issues, frozen evaporator coils or refrigerant leaks.

Finally, examine the manufacturer's warranty to know their confidence in the product.

When buying a residential AC system, work with a reliable dealer that offers a wide range of air conditioning systems and understands your home's cooling and heating needs. At Air Comfort, we are renowned for our expertise and experience in residential air conditioning systems. Contact our team today for high-quality products and residential AC system installation. We look forward to helping find the right AC system for your home.

How to Buy and Install a Commercial Air Conditioning System

websitebuilder@thryv.com — Thu, 09 Dec 2021 22:50:42 GMT

How to Buy and Install a Commercial Air Conditioning System

Heating ventilation and air conditioning (HVAC) systems are often a must-have in any modern commercial building. Tenants and lessees usually need these systems to keep their offices and retail spaces comfortable regardless of the weather. Below is a guide with some factors to consider when installing an air conditioning system in your commercial building.

Consider a professional assessment

An oversight most business people make is that they buy the AC system without asking for a professional assessment. However, this is probably the most crucial stage of installing the AC system. The HVAC professional will examine the following:

The energy necessary to heat the building. Typically, they calculate the British thermal units to determine the size of the AC.
The possibility of renovations for the building before the installation. For example, you may need to repair or replace the ducts.
The ordinances that could affect the AC system you purchase. For instance, you may be prohibited from using a loud AC system at night.
The length of time to install the system. This is a critical concern if you have tenants or ongoing works inside the building.

Choose an appropriate system

You have many models of commercial AC systems. Therefore, you might be overwhelmed as you compare the various systems. The guide below should help you narrow your search to a specific system.

The type of AC system

In most cases, you will have to choose between a split and central air conditioning system. Central AC systems are perfect for buildings with existing ductwork. They are also affordable and allow you to warm the rooms evenly.

Split air conditioning is perfect for buildings that do not have ductwork. A significant benefit of these systems is that they are easy to install and easily blend with the interior.

The features of the AC system

Temperature zoning is often an essential feature of any commercial AC system. This enables you to create temperature zones inside the facility. For example, you could choose only to warm the ground floor when the other floors are unoccupied.

Modern AC systems come with a smart feature that allows you to control the AC remotely. This feature is essential in commercial buildings since tenants could leave the AC on when they are no longer in the office. Besides, the system can often inform you of any AC defects.

Other features to look out for in the AC system include dehumidifiers, air purifiers, thermostats, thermal expansion valves and fan-only switches.

The energy consumption of the AC system

Energy consumption is a concern for most businesses. Modern AC systems come with a star rating that informs buyers about the energy efficiency of the system. Although you will spend a bit more on a system with a high energy efficiency rating, your business will often make long-term savings.

The durability of the AC system

Buying a durable AC system will help reduce the costs of maintaining your commercial building. Online reviews are a sure way to compare the various systems on the market. You could also interview people with commercial AC systems and assess how they rate the different brands and models.

Go for professional installation

The golden rule of commercial AC installation is working with an accredited HVAC contractor. Most contractors have the expertise necessary to conduct HVAC, electric and plumbing works required when installing the AC system.

The contractor will create an installation plan detailing how they will install the ductwork or piping, create temperature zones, place indoor and outdoor units and improve the efficiency of the system and reduce noise.

Choosing and installing a commercial AC system can be a daunting task. At Air Comfort , we credit ourselves with the technical expertise necessary to recommend and install a commercial AC system. Contact our team today and enjoy our exceptional services.

4 Signs That Your Air Conditioning System Needs a Maintenance Check

websitebuilder@thryv.com — Tue, 10 Aug 2021 01:29:41 GMT

Air conditioning systems all need occasional maintenance to keep them working as efficiently as possible. By dealing with minor maintenance issues when you notice them, you might be able to avoid expensive repairs in the future. Watch out for these signs that your air conditioning system needs a maintenance check and call a local HVAC service if you notice any of them.

1. Insufficient or slow cooling

If you notice that your air conditioning system is not performing as well as it used to, leaving you sweating on hot days or waiting ages for your home to heat up in winter, then you should schedule a maintenance check to find out what the problem is. First, check the temperature settings to ensure that the problem is with the air conditioning system and not simply with the settings you have chosen.

For ducted systems, tears in the ducts or ducts that have come loose can cause insufficient cooling or heating by allowing cold air to leak out of the system into the attic or crawl spaces in your home. Another possibility is that the condenser has developed a fault that prevents it from adequately cooling the air in the first place. A local HVAC service can diagnose the problem and let you know what they need to do to fix it.

2. Soaring energy costs

If the amount your household spends on electricity is going through the roof in summer or winter, then a fault in your air conditioning system could be to blame. Poorly maintained air conditioners often use a lot more electricity than systems that are in good condition.

Scheduling a tune-up for your air conditioner could help you to save money over the long term. HVAC technicians can change the filters, clean the unit, replace any damaged parts, and generally restore your air conditioning unit to efficient operation, which should reduce the amount that your household spends on electricity each month.

3. Foul odours

If there is a bad smell coming from your air conditioning system while it is running, then that is a clear sign that the unit requires maintenance. It could be that a fault in one of the key components is creating a damp environment inside the unit, leading to the growth of mould. Another possibility is that some small creature has gotten inside the air conditioning unit and died.

In contrast, an air conditioning unit that smells like burning likely has a part that is wearing out. Continuing to use a unit that smells this way could result in it breaking down completely, so it is best to seek help as soon as possible.

Rather than trying to deal with the unpleasantness of a smelly air conditioning unit yourself, call an HVAC service. Technicians have experience in dealing with all kinds of air conditioning smells and can quickly identify and solve the problem.The body content of your post goes here.

4. Abnormal noises

A well-functioning air conditioning system does not rattle, grind, pop, or bang while it is running. If your system starts to make any of these abnormal noises, you should call an HVAC maintenance service so that they can check over the unit and work out what is causing the sound. It might be that a component inside the unit has experienced excessive wear and tear and is now on the brink of breaking down.

If you notice any signs that your air conditioning system has developed a problem, reach out to us today to schedule a maintenance check.

4 Reasons to Install a Ducted Air Conditioning System

Tue, 09 Mar 2021 15:28:36 GMT

If you find it difficult to keep your home cool in hot summer months, then you might want to install new air conditioning or upgrade your current cooling system. In either case, you might want to think about a ducted solution.

These systems run from a central unit. The unit sends air-conditioned air into your home through a network of grilles in individual rooms.

What are the benefits of installing ducted air conditioning?

1. Get a whole-house solution

Some air conditioning solutions, such as split systems, struggle to cool large spaces or multiple rooms. You need an indoor unit in each room that you want to cool; you might find it hard to find a single system that can run enough units for your needs.

While these systems can work effectively in apartments or smaller homes, they aren't always the best solution in larger properties. However, if you install a ducted system, then you get air conditioning wherever you want it in your home.

The central unit guides cooled air throughout its system efficiently. If a room has a connected grille in it, then the system can cool the room down.

So, designing a whole-house solution is easier. Plus, if you choose a reverse-cycle ducted product, you can also use the system to heat your home when the weather is colder.

2. Create controllable zones

While having air conditioning in every room in your home might be a relief, you might also worry about how this will affect your energy usage and bills. However, this kind of whole-house system doesn't have to be expensive to run.

A ducted system is often more efficient than systems where you have to run units more often and at higher speeds to try and spread cooled air around your home. Typically, you can control how and where ducted air conditioning works. You can program the system on a room or zonal basis.

For example, you can set a timer to have the system come on when you know you want to cool things down, say a couple of hours before you get home from work. Or, you can set zones where the system runs at different times or at different temperatures.

So, if you don't see the point of cooling your bedrooms during the day when you won't be in them, then you can focus your cooling in the rooms you will use. As you get close to bedtime, you can set your bedroom zones to cool and switch off the system in your living areas.

3. Minimise space loss

Air conditioning systems can take up space around your home. For example, if you use individual units, then they take up a fair bit of wall or ceiling space. You might not be able to install a unit in the optimum position if you don't have room for it in the right place.

Ducted air conditioning doesn't have this kind of footprint. The primary unit is hidden away. While you do need somewhere for the grilles to go, this shouldn't be a problem.

Grilles come in various shapes and sizes, and they don't have to take up much space. Your air conditioning spread will be more effective in each room, so you don't have to worry about placement as much.

4. Get a more discreet solution

Many air conditioning units don't always look great in the home. Some people feel that they look clunky and out of place. They can detract from a nicely decorated room. Plus, some systems are noisy.

A ducted air conditioning solution is often more discreet, both cosmetically and acoustically. Its grilles are subtle and unobtrusive. The system itself should also run more quietly.
