5 Things to Know Before Buying cabinet air conditioner

What To Consider Before Buying An Air Conditioner

Having an air conditioning has become one of the essential elements for general well-being in people’s homes and businesses.

With competitive price and timely delivery, Lingji Jingke sincerely hope to be your supplier and partner.

For many, it is an absolute necessity, and the truth is that we cannot blame them for it. Instead, air conditioning is an essential solution to creating a comfortable environment.

Good air conditioning guarantees better rest, relaxation and mental and physical health. And at work, it can help increase productivity and reduce stress. Nobody likes to work uncomfortably, right? Isn’t it better to work without continually thinking, “OMGsh! How hot is it” or “I’m freezing”?

BUT…there are several things to keep in mind because nobody wants to get stuck with the wrong AC.

I have seen cases where an air conditioner was installed in the wrong spot, and the entire system had to be replaced. That’s an expensive problem that you want to avoid at all costs.

So, to make sure that doesn’t happen to you, read this article, “The Top 10 Things To Consider Before Buying An Air Conditioner”, to the end. This will give you guidelines on what to look for when buying and installing an Air Conditioner.

1. What Type of Air Conditioner Should I Get?

There are several types of air conditioning and many different brands on the market. When looking for an AC for your home or business, the options are reduced to a few.

So, before we go into more depth, I’ll show you some of the most popular types with some pros and cons.

Split System Air Conditioners

Ducted System Air Conditioners

Window Wall Air Conditioners

Portable Air Conditioners

2. What Size Air Conditioner Do I Need?

One of the most important initial steps for installing Air Conditioning is to make sure you select the correct size.

When we talk about air conditioner sizing, we are not referring to the dimensions of the appliance itself but the cooling capacity in kW.

Many factors can impact the size that you’ll need. Some of them are:

• The size of the room, and unit position
• The insulation of the walls and ceiling
• The composition of the walls
• The windows and openings

To achieve the best efficiency and performance, you must ensure that you install the size of the room you want to air condition. 

Having an undersized Air Conditioner installed in a large room is about as good as an ashtray on a motorbike. A large room cannot be cooled by a unit only designed for a small space, while a unit that is oversized gets a room too cold, and would be wasting electricity.

Calculate the size that you need

Generally, in Australia, you will need 0.12 to 0.15 kW of power per m². Now, to calculate the square meters you need to multiply the length and width of the floor of the room. The result will be the square meters of that area.
e.g. 5m length x 4m width = 20m²

Air Conditioner Sizing guide

I have put together a rough guide to the different air conditioner sizes that you’ll need to cool a particular room size.

3. What Is The Best Place For Installing Air Conditioning?

The room and the position where you place the indoor and outdoor unit play an important role in the efficiency and performance of your air conditioning.

Where do I install the indoor AC unit?

Not all rooms have the same air conditioning needs. I always start with the drain. You can think you have the best spot for the unit, but if the drain doesn’t flow, it is a huge problem. Once that is taken care of, then choose the position which will provide the ideal amount of airflow. The function of the unit has to be taken into account before its appearance.

Where do I install the outdoor AC unit?

As for the outdoor unit, it As for the outdoor unit, it needs to be placed in a well-ventilated position.

In cool mode, the outdoor unit transfers the heat once inside to the outdoor unit. If a fence or obstacle is in the way, the unit can overheat, causing it to run inefficiently.

The outdoor unit should be installed as close as practical to the indoor unit position to maximise the system efficiency and minimise losses. Most good brands of air conditioners can have the outdoor unit installed up to 20m from the indoor unit without having to add additional refrigerant. However, it’s always best to keep the distance under 5m where possible.

4. What is Energy Efficiency and why is important?

The energy efficiency of air conditioning and heating is generated by each kW of energy consumed. The higher the power generated for each kW spent, the more efficient the unit is.

Every electrical appliance has a label with a different star rating. This energy label allows consumers to quickly and easily know the energy efficiency of their appliances.

In your case, you’ll want to know the energy efficiency of air conditioning to find out which one will consume less power to run. 

Why is important to have an Energy Efficient Air Conditioner?

• Save on energy consumption: If your air conditioning is efficient, you can reduce your electricity consumption by 30%.
• Better operation: The efficiency of the air conditioning is related to the good operation of the equipment. I recommend checking its operation periodically.
• Environment: If a unit is more efficient, its energy consumption will be much lower and, therefore, it will have a less negative impact on the environment.
• Less maintenance: We will avoid constant maintenance for malfunction and extend the equipment’s lifespan. An efficient air conditioner would have at least three more years added to its lifespan.

Which type of Air Conditioner units are the most efficient?

Generally, the most energy-efficient type of air conditioner you can buy is a split system. You will notice that the smaller the size of the unit, the more energy efficient they are.

That’s because energy efficiency is based on power consumption, not on how effective the system works.

If you size a unit correctly and choose one of the major brands, I wouldn’t fuss too much over the energy rating. Anything that heats or cools is going to use a lot of power.

5. How Much Does It Cost To Run An Air Conditioner?

Although air conditioning systems have different consumption depending on the brand, the size system and how old it is, it is essential to understand that the kW (kilowatts) size of the unit is how we measure the cooling capacity, but this is not the energy consumption of the unit. Just to confuse you the power consumption is also measured in kW but is only a fraction of the unit cooling capacity rating.

For example, a Panasonic 2.5kw air conditioner (model CS/CU-Z25VKR) has a power consumption of 0.5kw per hour.

As for the daily hours we use, let’s assume that your AC is running around 6 hours per day (3kW) of power.

If we multiply by the average of a week, it would be 7 days x 3 kW = 21 kW of weekly power expenditure.

Then, to calculate the weekly cost, we will simply multiply that figure by the cost of kW (e.g. 25 cents/kWh in Queensland), and we will obtain the total monthly cost as a result.

21 kW x $0.25 = $5.25/week. (This cost is approximate. Calculated per unit)

Cooling vs. heating Which one consumes more energy?

Air conditioners consume more power when they have to work harder, and the by-product of any electric machine is heat!

This is why your air conditioner will always have a higher heating capacity than its cooling capacity. 

As a heater, an air conditioner is quite effective and can reach temperature quite quickly. Typically, we tend to run our air conditioners for extended periods in cooling mode, resulting in higher power consumption when trying to cool a room.

Quick tips for reducing running costs

• Choose the right AC size
• Check the Energy Rating and choose an AC with a good energy rating
• Ensure regular maintenance of your unit
• Turn on the aircon only when you’re at home

6. How Noisy Should an Air Conditioner Be?

Another important thing that people often overlook when buying an AC is the noise level. You know how annoying it is to have constant background noise when you’re trying to focus on your tasks, right?

Then make sure you check the noise levels before you buy any air conditioner.

To get an idea of what the noise levels look like, check out this table.

Each unit has a different noise level of operation and you should be able to find that in its product specifications. Ideally, the noise levels should be under 50dB.

7. What is Inverter technology and why is important?

The solar inverter is an electronic component that alters the compressor’s speed. The inverter regulates the compressor’s pace, so it always works at a constant speed and, therefore, more efficiently. The application of inverter technology in air conditioning equipment affects energy savings.

On the contrary, in non-inverter units, the compressor always works at maximum speed, following an all-or-nothing principle: it operates at maximum performance until it reaches the desired temperature and then stops. Then, when the temperature moves away from the desired one again, it starts working at full power.

By working the compressor continuously with inverter technology, you can notice around a 50% reduction in energy consumption compared to conventional devices.

8. Do Air Conditioners improve air quality?

AC systems improve people’s quality of life, providing a more comfortable environment. In addition to achieving the right temperatures and reducing humidity, air conditioning units can renew and filter the indoor air, removing microparticles from the environment, thus making the air you breathe cleaner.

When installing Air Conditioning, look for units with air filtration systems to remove allergens, mould, bacteria, odours and dust from the air. The only brand of split system and ducted air con to have Asthma Council approval is Panasonic with their Nanoe-G technology. 

Proper maintenance and cleaning of your unit will reduce the build-up of dust and mould growth; this also helps keep the unit running more efficiently.

9. What should I know about maintenance before installing Air Conditioning?

After installing the air conditioner, we usually recommend a maintenance service every 6 or 12 months. However, depending on how much you use it and the quality of the appliance, this time may vary.

This maintenance ensures that the unit is working correctly; that the filters are clean to guarantee air quality, and that the system is running at the right gas pressures. As a homeowner, filter cleaning is a must to keep your unit running correctly. For more information, read about the importance of air conditioning service.

10. When, where and who to trust to buy Air Conditioning?

Part of the key when buying an air conditioner is getting good technical advice and back-end support. Many times, to save on costs, people get someone to install it cheaply. However, later they notice that the system is cooling or something else is a-miss.

All systems take a certain amount of labour and parts to complete the job, it just depends on your installer’s experience and how thorough of a job they do.

Make sure you choose a good air conditioning installer to avoid getting stuck with the wrong system, which can lead to excessive electricity costs and potential warranty issues.

When is the best time to buy Air Conditioning?

Like everything in Australia, peak season means higher prices. When we talk about air conditioning, this refers to summer or mid-winter, when everyone is looking for it.  Installers get really busy during this period, so you might have to wait a few weeks to install your unit.

Most manufacturers offer cash-back promotions once or twice a year in the quieter months to boost sales, that is the best time to buy a system so you can save time and money.

If you’re on the Sunshine Coast, we at Tenmen Electrical offer great prices all year round. Contact us to learn more about our special offers.

Where to buy Air Conditioning?

The best option is to find an air conditioner installer who can take care of the whole process from the supply and installation to the maintenance and repair of the unit, this greatly facilitates the process and can save you a lot of time, money and headaches!

Who should I trust to install my Air Conditioner?

If you live in Australia, look for a licensed air conditioner installer with ARCtick approval. Some traders offer just installation, but I advise finding a company that does all the processes of supplying and installing, so you don’t need to worry about anything.

In addition, I’d recommend looking for an air conditioner installer with an electrical qualification, as your AC needs to be wired around your home or business. In Australia, you can look for Master Electricians Australia certification.

Find an expert in your area who can recommend and advise you on the best options for your specific situation. Unfortunately, no one solution fits everyone.

Conclusion

After reading this guide, I hope you are confident about what to look for when buying air conditioning. Remember that no solution fits all homes or businesses.

To sum up, when installing air conditioning:

Confused about home heating and cooling? It turns out you’re not alone. According to Consumer Reports, it turns out that 20 percent of Americans reported needing to repair or replace their HVAC systems in the last year – but the majority felt overwhelmed with the process.

If you don’t know where to begin, don’t worry. Before you start a project or make a major HVAC purchase, we can help you get up to speed on what you need to know to make the best choice for you and your home.

HVAC Meaning: What is HVAC? 

HVAC stands for heating, ventilation and air conditioning systems. This system is responsible for heating and cooling your home and includes products like furnaces, air conditioners, heat pumps as well as ductwork, thermostats and other home comfort controls. 

While the world of HVAC might seem complicated, it doesn’t have to be confusing for homeowners. Once you learn a little more about how the systems work, the HVAC meaning and all the technical components will make more sense, and you can learn even more by watching this video that discusses HVAC and working with an expert dealer.

What is an HVAC system?

There are many moving parts that work to not only warm you in winter and cool you in summer, but also filter and purify your air to help protect you and your family from allergens, pollutants, and harmful chemicals. Breaking down the different parts of an HVAC system, or the heating and cooling products within homes, can help you to understand each system’s role in bringing you comfort throughout the year. Watch this video on how HVAC systems work to learn more details on heating and cooling systems and how you can achieve optimal comfort in your home and get more information on each system below.

Most people understand that a furnace heats a home, but don’t understand all the intricacies involved in the system. All furnaces consist of four main components: 1) burners that deliver and burn fuel, 2) heat exchangers, 3) a blower and 4) a flue that acts as an exhaust for gaseous by-products. A furnace generates heat by burning fuel and distributes the generated heat throughout the house.

Air conditioner

An air conditioner draws heat energy out of the house and transfers it to the outside air. The most common setup for residential homes is a split system, which includes an inside-the-home evaporative heat exchanger and an outside condensing unit heat exchanger.

Heat pump

A heat pump is an energy-efficient option to consider if you live in a mild climate zone. It uses the outside air to heat a home in winter and cool it in summer. Heat pumps are often misunderstood by homeowners, especially as a cooling system given their name contains the word “heat.” In the simplest sense, a heat pump “pumps heat” from one place to another, moving heat out of your home when you want it cooler, and pumping heat into your home when you want it warmer.

Air handler

An air handler most commonly works with a heat pump to circulate air throughout your home. If you’re searching for a traditional air conditioner or furnace, you won’t need an air handler as those systems have the internal parts needed to circulate air.

Ductless systems

A ductless HVAC system or mini split is a heating and cooling system designed to deliver warm or cool air to a single room or several without the need for connective ductwork. Mini split systems are a great option for room additions, sunrooms, garages or areas of the home that need to be warmer or cooler. Ductless systems are a great option to heat or cool a single room in your home without the hassle of adding ductwork. 

Thermostat

A thermostat, located inside your home, is a regulating device that allows you to control your indoor temperature. Thermostats are generally split into two classifications: traditional or connected controls. Basically connected, or smart thermostat controls, can integrate with other smart home systems and learn over time how to most efficiently heat and cool your home. Traditional thermostats are simpler — but several offer programmable features as well.

There are many ways to save on a new Trane HVAC system. Talk to your local dealer about how to save on local rebates, tax credits, and special, limited-time offers. Here are some of the main factors that affect the cost of a new heating and cooling system.

Location

Region and climate matter when finding the right system for your home and saving energy. The heating and cooling needs will differ in the hot and humid south and cold north. Also, installation costs can vary by as much as 20% depending on where you live.

Home size and construction

A large home will need a larger unit or even multiple systems to properly maintain a comfortable temperature — which of course will cost more than a smaller home. In addition, proper seals on windows and doors and the quality of your home’s insulation will affect your monthly heating and cooling costs.

Ductwork

Ductwork plays a crucial role in determining how comfortable your home is from room to room. When properly designed and installed, a duct system can maximize comfort and minimize energy use. If you’re installing a new HVAC system in a newly constructed home or replacing ductwork in a current home, adding ductwork will add as much as $2,000 - $3,000 to the total cost of your HVAC system.

Project difficulty

If your new system is planned for a hard-to-reach space or if you live in a historic home that requires retrofitting, you’ll see your HVAC installation price increase. Only with an onsite evaluation will these kinds of costs be discovered.

Indoor air quality and connected smart thermostats

Along with your traditional heating and cooling system, you have options to enhance the overall indoor air quality of your home with a Trane CleanEffects™ air cleaner or add climate zones with a ComfortLink™ II Zoning System or take advantage of the latest smart home, connected thermostat controls.

HVAC is very technical and it can be hard to make sense of all the acronyms, terms, and abbreviations. Here are a few top terms to help demystify the products to help you understand heating and cooling technology better – so that you can choose the HVAC system that is right for you. 

• AFUE–Measures a furnace’s efficiency in converting heat to energy. A higher percentage means higher efficiency and lower energy costs.
• SEER2–Measures air conditioner or heat pump cooling efficiency. A higher number means greater efficiency and lower energy costs.
• HSPF2–A ratio for the heating efficiency of heat pumps. An HSPF of 7.8 HSPF2 or more is considered high efficiency.
• Split system–A split system has two parts: an outdoor unit and an indoor unit. Split systems are the most common HVAC systems in modern homes.
• Packaged system–Packaged systems are all-in-one solutions, with most of the components for heating and/or cooling housed in a single cabinet.
• Heating stages –Refers to the number of settings a furnace or heat pump has. Variable or multi-stage systems offer more precise temperature control and run more efficiently than single-stage systems.
• Cooling stages –Refers to the number of settings an air conditioner or heat pump has. Variable or multi-stage systems offer more precise temperature control and run more efficiently than single-stage air conditioners.
• ENERGY STAR®–The ENERGY STAR designation is designed to help consumers identify energy-efficient products.
• Hybrid system–A hybrid dual fuel system is an electric heat pump combined with a gas furnace.

Whether your HVAC system is new and still under warranty or over 10 years old; routine maintenance service can get you ready for the upcoming season, lower your energy bills, extend the life of your system, and catch problems before they become costly repairs.

Scheduled HVAC maintenance includes items such as the following:

• Filter replacement
• Cleaning coils and condensers
• Replacing worn parts
• Clearing clogs or drain problems
• Checking for leaks
• Changing batteries, as needed
• Inspecting ducts for dust, mold, and debris
• Checking electrical system connections
• Inspecting blowers for airflow
• Inspecting heating elements or the heat exchanger
• Checking gas pressure
• Lubricating moving parts, such as bearings and motors
• Checking that assembly is in order
• Ensuring all parts are in good working order

It is easiest to remember to schedule maintenance for each system if you follow this standard:

Heating system (furnace or heat pump)

Schedule an appointment in late summer or early fall, before the heating season.

Cooling system (air conditioner or heat pump)

Schedule an appointment in late winter or early spring, before the cooling season.

If your home’s heating and cooling systems are no longer keeping you comfortable, it may be time to decide whether to repair or replace your HVAC system. There are some warning signs that it may be time to replace your HVAC – or if your HVAC system is no longer under warranty and the repair costs are getting too high.

Replace your system when:

• It needs frequent repairs.
• It’s suffering from poor performance.
• Your energy costs rise.

Replace your air conditioner if:

• It’s over 10 years old.
• Is rated 10 SEER or less.

Replace your furnace if:

• It’s over 15 years old.
• Is rated 80% AFUE or less.

Replace your heat pump if:

• It’s over 10 years old.
• Is rated 10 SEER or less | 8 HSPF or less.

Financial Tip: Follow the $5,000 Rule

Take the age of the equipment and multiply that by the estimated repair cost. If the number is more than $5,000, then you should consider replacing your unit.

Now that you know the basics, talk to your local Trane dealer for a detailed evaluation and recommendation for what heating and cooling solution is right for you.
