Key Takeaways

  • Picking the right aircon depends on many things like how big your room is, how much energy it uses, and how noisy it is.
  • Aircons with inverter technology are better because they save more energy and make less noise.
  • The amount of cooling you need, measured in BTUs, changes depending on room size, how many people use the room, and extra heat from appliances.
  • It’s smart to think about air quality and comfort features like HEPA filters for clean air and smart thermostats for easy control.
  • Before buying an aircon, consider your budget including both initial costs and future running expenses.

Types of Air Conditioners

We know choosing the right aircon can be a bit tricky with so many options out there. You’ve got portable units, great for moving around rooms without fuss. Then there’s the window and casement types, perfect for single rooms and easy to install—just right for bedrooms needing 6,500 to 9,000 BTUs of cooling power.

For larger spaces like living rooms, central air conditioners are king. They pump cool air through ductwork throughout your home but need more juice—about 12,000 to 24,000 BTUs. If ducts aren’t your thing or you’re looking for something a bit more flexible installation-wise, check out ductless mini splits.

These offer System 3+1 flexibility without needing any invasive installations. And let’s talk about inverter models; they save energy and keep noise down but come with higher upfront costs compared to non-inverters which are easier on the wallet and quicker to set up.

Each type suits different needs—from room sizes and installation ease to energy efficiency and noise control. We make sure our customers find what works best for them by offering a range of systems specifically suited for their homes.

Cooling Capacity

Cooling capacity is key. We measure it in British Thermal Units (BTUs). For a quick calculation, you multiply your room’s square footage by 25. Say your flat is the usual size; you’ll need about 9,000 BTUs to keep cool.

But it doesn’t stop there. If your place sits higher up, add another 10% to that number. Got lots of shade? Then you can reduce it by 10%. And if more than two people are living there, throw in an extra 600 BTUs for each person.

Don’t forget about your gadgets and appliances either—they heat things too. So, for every electrical device humming away in your space, tack on another 4,000 BTUs to ensure everything stays chill.

Energy Efficiency

We always look for ways to save money and keep our homes comfortable. That’s why picking an air conditioning system with high energy efficiency is key. Air conditioners with a 5-tick rating from the National Environment Agency (NEA) are top-notch for energy saving.

They use less power and cut down costs over time.

Now, here’s something interesting about inverter technology—it changes how much power your cooling unit needs without turning it off and on all the time. This means your aircon uses just the right amount of energy to keep you cool, reducing electricity bills even more.

So, when choosing an air conditioner, we make sure it has inverter tech to give you better efficiency and lower running costs. At iCare Aircon, this makes a huge difference in staying comfy without spending too much cash on bills.

Noise Level

Noise is a big deal when you’re picking an air conditioner. We know loud sounds can bother sleep and relaxation at home. That’s why inverter air conditioners are great—they make less noise compared to non-inverter types.

Decibels measure this sound, and lower numbers mean quieter operation.

Choosing a quiet model adds comfort without disrupting peace. Look for units with low decibel levels; it makes living spaces more enjoyable. At iCare Aircon, we focus on providing options that ensure your environment stays peaceful, perfect for anyone who values tranquillity in their home.

Size and Dimension

We know the right size aircon makes all the difference. It’s not just about big or small; it’s about perfect fit. Homes with compact living spaces need aircon with properly sized compressors.

If an aircon is too small, you’ll see signs like constant operation and low airflow. This also means your rooms won’t cool evenly.

Choosing involves more than guessing. You must understand unit size versus space size. An oversized air conditioner isn’t good either – it can lead to short cycling, hurting efficiency and comfort.

Plus, don’t forget residential restrictions on where you can place external units. At iCare Aircon, we match your space to the ideal unit dimensions, ensuring efficient cooling every time without unnecessary noise or energy waste.

Installation and Maintenance

Our team at iCare Aircon completed over 600 installations last year. This shows our commitment to providing top-notch service. Installing an air conditioner right is key for it to work well.

We make sure the compressor size matches your home’s needs, ensuring efficiency and comfort.

Maintaining your aircon is crucial for keeping it running smoothly. Regular checks prevent common problems like refrigerant leaks or dirty filters. These issues can lead to bigger headaches if not addressed early on, such as higher energy bills or a fully broken system.

We handle your maintenance with care, using the best tools and parts for each job, from vacuum cleaners to quality replacement filters and coils.

Location Considerations

We always adjust the cooling power based on where your room sits. For high places, we add 10% more BTU since they get hotter. If your room is mostly in the shade, we take away 10%.

Think about larger air conditioners for spaces with high ceilings or big windows. The sun’s path and nearby heat sources also change how much cooling you need.

For example, if a kitchen gets afternoon sun, it’ll need a stronger air-con system than a shaded bedroom would. We look at all these details to make sure you get just the right amount of cool air.

Plus, knowing this helps us keep your energy bills low while making sure you stay comfortable.

Number of Occupants

We always keep an eye on the number of people living in a space. It changes how much cooling is needed. For every person above two in a room, add 600 BTU to your air conditioner’s capacity.

This rule helps us make sure your home stays comfortable without wasting energy.

In HDB flats, we start with 9,000 BTU for basic needs. But if more people live there, we increase the BTU accordingly. This ensures everyone stays cool and happy, even during hot weather.

Rely on us to calculate the perfect size for your aircon needs based on these numbers.

Heat Generation in Home

Our homes can get hot, especially with all the gadgets and appliances we use every day. Every electrical device adds heat to our rooms. This means our aircon has to work harder to cool down the space.

We often add 4,000 BTU to our cooling needs just for these electronics.

Also, where the sun hits our house affects how warm it gets inside. Rooms that face the sun directly will be hotter. So, we always consider this when deciding on the right size of air conditioning unit.

It’s not just about room size but also about what makes the room warmer than normal.

Room Type and Size

We know the size and type of your room matter a lot for picking the right aircon. Small bedrooms in HDB flats need an aircon with 6,500 BTU, while larger master’s bedrooms require at least 9,000 BTU.

If we’re talking about living rooms, you’re looking at needing between 12,000 to 24,000 BTU depending on the space. It gets more complex with bigger spaces like double-volume rooms or those with large windows; they always need bigger units to stay cool.

To find out how much cooling capacity your room needs, take the floor area of your aircon space and divide it by 5. This gives us a starting point in Btu/hr which we can then adjust based on other factors such as sun exposure or electronic devices that generate heat inside the room.

For every kW increase in power supply demand from devices like TVs or computers, multiply it by 3,412 to match it up with the right BTU needed for efficient cooling without overspending on energy consumption.

Comfort Features

Our air conditioners come packed with features to boost your comfort. With HEPA filters, they trap small particles like dust and pollen. This means cleaner air in your home, and less risk to your health.

Plus, our models with inverter technology adjust cooling power. They save energy and cut down on noise—a win-win.

Smart thermostats give you control over temperature from anywhere. Forget adjusting the dial manually; set it from your phone for perfect climate control when you get home. Dehumidification options pull excess moisture out of the air, keeping away that sticky feeling during hot months.

For us at iCare Aircon, ensuring these features work together smoothly is a priority so you can enjoy cooler temps while protecting furniture and electronics without worry.

Construction Material and Insulation

We know choosing the right aircon involves many factors. Construction materials and how well a home is insulated are key. Good insulation means your aircon doesn’t have to work as hard.

This saves energy and money.

Homes built with sturdy materials keep cool air in better than those that aren’t. We always suggest checking insulation around windows, doors, and walls. Upgrading can make a big difference in how well your cooling system works.

Insulation impacts cooling needs more than you might think. A well-insulated room requires a smaller aircon unit, reducing costs over time. Whether it’s adding sealant around windows or upgrading wall insulation, these steps ensure efficient cooling.

Materials like stone and brick are great for keeping a house cool. Keep this in mind when thinking about your air conditioning needs. Efficient homes need less power from their units to stay comfortable.

So, making sure your place is sealed tight against heat makes our job easier—and keeps you cooler for less money.

Budget Planning

Planning our budget starts with knowing air conditioner prices. Prices vary by type like split, portable, or central systems. Energy-efficient models from trusted brands such as Carrier and Mitsubishi Electric might cost more upfront but save money in the long run on electric bills.

We consider repair costs too.

Choosing a non-inverter aircon saves installation time and expense. It’s less costly upfront compared to its counterparts. We look at future expenses, thinking about how often we’ll need servicing to avoid problems like unusual noises or poor cooling.

This helps us pick an aircon that fits our budget while keeping our home cool effectively.


Choosing the right air conditioner shapes your home’s comfort. With options from System 1 to Solar Aircon, finding a fit seems tricky but it isn’t. You must consider room size, energy use, and noise levels.

For any advice on quiet, efficient systems that suit our tropical climate, reach out to us at iCare Aircon at Our experience ensures you pick wisely, enhancing your space’s coolness without worry.
