Factors to Consider Before Buying an Inverter Air Conditioner
You’ve decided to buy an inverter AC. Now that you’re ready to make your home more comfortable, here are a few factors to consider.
Room Size
The size of the room where you’ll install the AC unit is exceptionally significant. It’ll be challenging for a small inverter AC to cool or heat a massive room.
The opposite is also true. You don’t want an oversized AC for a small area. A 1.5-ton device can cover between 140 and 180 sq. ft., while you may need to go up to a 2-ton unit for larger spaces.
Air Quality
The ideal air quality provides you with comfort in your home. Ensure that the inverter AC can help reduce humidity while cooling your house. If it includes an air filter, make sure it can remove dust and other air particles from your home.
Cooling Capacity
If you’re living in a region with high temperatures, you’ll want to make sure that the inverter AC can bring it down. This measurement is displayed as British Thermal Units (BTU).
There are two fans, a thermostat, and variable speeds for different settings in the day. The best inverter ACs let you cool the air while not consuming too much power. For this measurement, you should look for the Seasonal Energy Efficiency Ratio (SEER).
Functions and Features
Not all inverter ACs are built the same. One of the top features to look out for is the Energy Star rating. It will ensure that the unit saves you as much power as possible, preventing you from spending your whole budget on the utility bill.
You should also see if it serves more than one purpose. While some inverter ACs can only cool, others have the additional function of heating. If you’re lucky, it can also auto-clean and diagnose itself for problems.
One more feature you should look for is an auto-restart function. If you suffer a power outage, the inverter AC will switch back on when the electricity is restored while retaining the previous settings.

What Is an Inverter Air Conditioner and How Does an Inverter Air Conditioner Work?
Unlike standard AC units, an inverter AC uses the latest technology to regulate a room’s temperature. The inverter controls the compressor speed, which adjusts based on sensors or your remote control.
In effect, the direct current (DC) inverter consists of a variable-frequency drive with an electrical component that’s adjustable. It manages the electromotor’s speed in the compressor, which shifts how much cool or hot air it pushes out.
It does this by transforming the AC to DC, with a modulation in the inverter that delivers the desired frequency. In the end, it produces the correct airflow at the right temperature no matter how much the room changes.

Types of Inverter Air Conditioners
There isn’t only one inverter AC type. You’ll need to evaluate each one to see which suits your needs best. Here are the three primary types.
Mini-Split Air Conditioner
When a central AC is out of the question, and you’re looking for the ductless option, you’ll aim for the mini-split AC. The compressor is located outside, with the indoor evaporator installed as close to the ceiling as possible.
The evaporator performs the heating and cooling, while it may also act as a dehumidifier. The condensation drain is on the outside, which you can feed into your garden or a bucket with a cable.

Portable Air Conditioner
Existing as a single unit, the portable inverter AC has wheels that let you move it around the home. There are generally fewer functions available, but you can focus it on a single living space rather than the whole house.
There’s also the benefit of packing it up and taking it with you on holidays. Some people also use it in their motorhomes.
Window Air Conditioner
Some homeowners prefer inserting inverter ACs in window frames. The drainage goes outside while the output faces into the home.
You can purchase units with adjustable brackets for the extra spacing in the frames, while others require you to buy additional spacers.
Advantages of Inverter Air Conditioner
Owning an inverter AC has several benefits for your home and lifestyle. Let’s take a look at some of the top advantages.
Cost-Effective
When compared to installing a central air conditioning unit, you’ll save your budget by purchasing an inverter unit. The components are also more cost-effective to replace, significantly lowering your maintenance expenses.
Energy-Efficient
Of course, you’ll also want to save on your utility bills. Inverter ACs consume less power than standard units, as they adjust fan speeds automatically throughout the day. You should also locate one that has a high SEER rating.
Better Cooling
Non-inverter AC units will remain at the same speed regardless of the heat in your living room. The inverter AC pushes the compressor to work faster, providing improved cooling when you’re facing a hot day.
Silent Operation
Since inverter and split inverter ACs run at a slower speed, you won’t hear them as much as standard units.
LG LW1019IVSM
Window brackets also assist in preventing rattling against the frame or glass.
Sound Sleep
The inverter AC runs silently to provide the optimal temperature and comfort throughout the night. If it has dehumidifier settings, you’ll also have less humidity in the air and less chance of contracting sickness or allergies while you sleep.
Disadvantages of Inverter Air Conditioners
While the benefits may convince you to buy an inverter AC, you need to also consider the cons. Here are some disadvantages you should consider.
More Sophisticated Maintenance
Since there is an inverter controlling the compressor’s speed, there are more intricate parts than the standard AC. Therefore, you can expect more complicated maintenance required if the system breaks down.
You may also need a specialized technician for specific devices. For instance, Daikin and Panasonic may require you to use their agents to repair components, costing you more than you’d expect.
Few Dehumidification Settings
The inverter AC mainly focuses on heating, cooling, and ventilation. However, some units also provide dehumidification to lower the high humidity levels.
The problem is that you can’t change settings for it like you can with actual dehumidifiers. It’s a side role that’s there to promote sales more than delivering any significant benefit.
Only Suitable for Specific Spaces and Climates
While the inverter AC can cool your home, it will struggle in intensely hot climates. You’ll find the compressor working harder than the manufacturer designed it to, increasing the utility costs.
You’ll also need to make sure you have the correct size for your home. As with warm climates, asking a small inverter AC to cool a massive house won’t change the temperature while incurring excessive expenses.
Inverter Air Conditioner Sizing
Warranty Stipulations
Most manufacturers provide warranty periods for the compressor and other parts. While this is welcome for most buyers, the problem arises with the installation and upkeep.
Sometimes, professional installers need to splice cables or adjust the housing for split or window units. In most cases, performing this act will void the warranty.
Who Should Not Buy an Inverter Air Conditioner?
If you own a massive home, you may want to consider installing central air conditioning instead. Furthermore, high humidity regions require a dehumidifier rather than an inverter AC.
If you’re facing issues with dust, allergens, or other air contaminants, you’re better off with a purifier. Make sure you purchase the right product for your requirements.
How Do Inverter Air Conditioners Compare to Other Popular Types?
We’ve already mentioned several AC unit types, but it may be beneficial to look at the significant differences with inverter ACs.
Inverter Air Conditioner vs Non-Inverter
The primary difference is that one has an inverter, and the other doesn’t. What this means for you is that the inverter AC can adjust the compressor’s speed to adapt to the ambient room temperature.
They both perform a similar function, though. Both will quickly cool, heat, and ventilate your room. You can also find the same types, such as split, portable, and window AC.

Inverter AC vs Split AC
A split AC has the evaporator on the inside while the compressor is on the outside with the drainage pipe. You can also get whole units, though, with both situated on the inside with the draining in a bucket or through a cable leading to the exterior.
While both perform the same function, the installation and maintenance costs for the split AC are higher. You may also find more advanced functions, depending on the model.
