Inverter air conditioners first appeared in Japan in 1980. They became popular worldwide for their efficiency and comfort. But they also had some drawbacks that made people hesitate. This article will explain the pros and cons of inverter ac to help you decide if it is right for you. First, let’s briefly explain what an inverter AC is.
What is an Inverter Air Conditioner?
An inverter air conditioner is a unit whose compressor’s motor speed is adjustable.
This adjustable compressor speed is the key difference between inverter and non-inverter models. A regular AC’s compressor cycles on and off. Meanwhile, the compressor of an inverter AC always runs at changing speeds.
For example, a conventional AC compressor shuts off once the desired temperature is reached. When the room warms up, it turns back on. This full-speed, on/off cycle has drawbacks: higher electricity use, wasting energy, more noise, and uneven cooling.
An inverter AC starts gradually. The compressor stays on even after reaching the set temperature. Instead of turning off, it adjusts its speed to maintain that temperature. This provides consistent comfort and saves energy.
Inverter vs Non-Inverter Air Conditioners (The Pro’s Cheat Sheet)
| Feature | Inverter AC | Non-Inverter AC |
| Compressor | Variable speed | Fixed motor speed (On or Off) |
| Energy Efficiency | Higher (High SEER rating) | Lower (Lower SEER rating) |
| Energy Consumption | Low power consumptions because it adjusts based on cooling needs | Consumes full power while running |
| Temperature Control | Precise and consistent | Fluctuates |
| Comfort | More comfortable | Might have temperature swings |
| Noise Level | Quieter operation | Relatively louder |
| Cooling Speed | Faster | Slower |
| Upfront Cost | High | Low |
| Lifespan | Relatively longer | Relatively shorter |
Pros of Inverter Air Conditioners
People are drawn to inverter air conditioners because of their energy efficiency. The ACs have much more perks than that.
Here are the advantages of inverter ACs:
1. Superior Energy Efficiency
The energy efficiency of an inverter air conditioner comes from its variable-speed compressor mechanism.
In a regular AC, the compressor consumes the maximum power when it is running. After reaching the optimum temperature it shuts off stopping the power consumption. When it needs a temperature change is needed, the compressor turns on again consuming huge power.
On the other hand, an inverter air conditioning unit rarely runs at a constant speed. The speed is just enough to change the temperature and hence, only the required power gets consumed. Additionally, an inverter AC doesn’t consume the extra power to turn the advanced compressor on like conventional air conditioners.
The reduced power consumption converts into lower electricity bills and major cost reductions over time.
Besides, inverter units typically have higher SEER ratings too. That means, these devices need less power overall to produce the same output.
2. Consistent Comfort
Because the inverter air conditioner continuously adjusts its heating/cooling output, it provides consistent comfort. Non-inverter air conditioning units either remain on or off. This commonly creates fluctuations in indoor temperatures. Inverter ACs eliminate this problem with their mechanism.
The newer inverter ones also allow precise temperature control and modes for faster heating or cooling performance.
3. Quieter Operation
Regular air conditioners’ compressors abruptly start/stop. This results in extra noise from the system. On the other hand, the speed changes are gradual in an inverter AC.
The gradual change doesn’t cause any excessive vibrations. So, it produces less noise. The low noise level makes it perfect for bedrooms, living rooms, and other quiet spaces.
4. Better Dehumidification
Inverter ACs run longer and have more consistent airflow. As a result, they have more contact time between evaporator coils and air. The amount of air is higher too from the airflow. This longer period removes more moisture than split or window air conditioners.
5. Durability and Longer Lifespan
From the absence of frequent on/off cycles, an inverter air conditioner has reduced stress on its compressor and other components. This results in lower wear and tear. So, the unit can run longer over the years. The more consistent operation also makes it more reliable with higher life expectancy.
6. Solar Power Compatibility
Many regular AC units (split or window) don’t run on solar power. This makes AC installation difficult for homeowners with solar panels. Inverter ACs, however, work seamlessly with the fluctuating energy output of solar panels. They save money with this advanced technology too.
Cons of Inverter Air Conditioner
With all the advantages mentioned, what could potentially be the downsides of an inverter air conditioner? The disadvantages of an inverter AC include:
1. Higher Initial Cost
With all the updated features, the inverter AC costs more. The price is comparatively higher than its non-inverter counterparts. This is a notable concern for budget-conscious buyers, even though they are energy efficient with higher cooling power.
2. Complex and Expensive Repairs
Air conditioning with inverter technology requires complex components. Parts like inverter boards can be expensive to repair or replace.
Inverter ACs also require expert technicians. Finding qualified technician for maintenance can also be challenging. The maintenance also needs to be regular.
3. Voltage Sensitivity
Components in the inverter AC are also more sensitive. So, the components are vulnerable to voltage fluctuations or power surges. The units may not be optimal for areas with unstable power supply.
Many modern inverter ACs have integrated surge protectors to lessen the risk.
4. Not Ideal for All Cases
An inverter AC may not be ideal for areas with extreme weather conditions and households with occasional AC runtime. Some inverter ACs are also complicated to install because of extra wiring and components.
Is an Inverter Air Conditioner Right for You?
You should choose an inverter AC if you:
- Use AC frequently or for longer periods.
- Prioritize efficiency and lower electricity bills
- Want a more comfortable and consistent temperature
- Prefer quieter operation
A non-inverter air conditioner would be better if you rather:
- Use your AC infrequently
- Have a tighter budget
- Minimizing energy use is not a major concern
Pick the one whose advantages and disadvantages suit with your criteria.
Key Considerations When Choosing an Inverter Air Conditioner
The benefits of an inverter AC are appealing. However, it is always better to be informed before making a decision. If you’re considering an inverter AC, keep these key factors in mind:
- Room Size: Matching the AC’s cooling capacity with the room size is the most important factor before purchasing an air conditioner of any type. You also need to consider factors like ceiling height, insulation, window size, usage, etc. before purchasing the air conditioner.
- Energy Savings vs Upfront Cost: The SEER rating of inverter ACs is higher. The required cost is also higher at the same time. You need to budget and plan accordingly to make up for the upfront cost with the savings from usage.
- Brand and Model Selection: Choose a reputable brand with good warranties. Look for customer reviews before purchasing a model.
- Features and Functions: Inverter technology is the feature that sets these types apart from the rest. Some people also prefer to compare airflow distribution, dehumidification capabilities, etc. Meanwhile, some also look for smart features like Wi-Fi connectivity.
Ultimately, you’ll need to decide on your preferred features within your budget. Look for available models and their reviews and consult for the proper size before purchasing an inverter unit.
Conclusion
Inverter ACs offer significant benefits like energy saving, consistent comfort, and quieter operation. They are ideal for people who use ACs frequently and want long-term savings. However, the higher upfront cost and complex maintenance compared to non-inverter counterparts can be a deal breaker for some.
If electricity bills, comfort, and quieter performance are your priorities, an inverter AC might be a great choice. On the other hand, a non-inverter AC could be better if you use ACs occasionally or have a limited budget.
Evaluate your needs, usage, and budget to make the right choice. An informed decision will ensure your investment brings comfort and value. Ultimately, choosing between an inverter and a non-inverter AC comes down to weighing the advantages and disadvantages based on your individual circumstances.
