Is Daikin AC Better Than OLMO? A Comprehensive Comparison

When it comes to choosing the right air conditioning system for your home or office, the decision can be overwhelming, especially when comparing top brands like Daikin and OLMO. This comprehensive guide will delve into the intricate details of these two leading HVAC manufacturers, helping you make an informed decision on which system is better suited for your needs.

Efficiency: Daikin Leads the Way

Daikin’s air conditioning units boast superior efficiency, thanks to their advanced technology. Their lineup includes variable speed compressors, two-stage, and single-stage models, all of which are designed to optimize energy consumption and provide exceptional cooling performance.

In contrast, OLMO offers units with up to 18.5 SEER2 ratings, which, while respectable, may not match the efficiency levels of Daikin’s offerings. It’s important to note that to achieve the stated SEER and EER ratings, the indoor and outdoor units must be AHRI matched, ensuring optimal performance.

Noise level is a crucial consideration for many homeowners and businesses, as a loud air conditioning unit can be disruptive and disrupt the peaceful ambiance. Daikin’s mini-split A/C systems are renowned for their exceptionally low noise output, producing only 19 dB, making them one of the quietest units on the market.

OLMO’s units, on the other hand, generate a slightly higher noise level of 25 dB. While this may not be a significant difference, for those seeking the ultimate in quiet operation, Daikin’s systems may be the preferred choice.

Warranty: Daikin Offers Longer Coverage

When it comes to warranty coverage, Daikin stands out with a 12-year warranty on the compressor and a 5-year warranty on parts. This extended warranty provides peace of mind and assurance that your investment is protected.

OLMO, in comparison, offers a 5-year warranty on the compressor and a 2-year warranty on parts. It’s important to note that OLMO’s warranty does not cover labor costs and is only valid if the unit is installed by a licensed HVAC installer.

Installation: Daikin Offers More Flexibility

Both Daikin and OLMO recommend professional installation for their air conditioning units. However, OLMO’s warranty is only valid if the unit is installed by a licensed HVAC installer, while Daikin’s warranty does not have this requirement.

This means that Daikin offers more flexibility in terms of installation, allowing homeowners or businesses to potentially save on labor costs by using a non-licensed installer, as long as the installation is performed correctly.

Advanced Features: Daikin Leads the Pack

Daikin’s air conditioning systems are renowned for their advanced features and cutting-edge technology. Some of the standout features include:

  1. Inverter Technology: Daikin’s variable speed compressors and inverter-driven motors provide precise temperature control, improved energy efficiency, and enhanced dehumidification capabilities.

  2. Intelligent Defrost: Daikin’s systems automatically detect and adjust the defrost cycle, ensuring optimal performance even in cold climates.

  3. Wireless Connectivity: Many Daikin models offer wireless connectivity, allowing for remote control and monitoring via smartphone or tablet.

  4. Dual-Barrier Coating: Daikin’s indoor units feature a dual-barrier coating that protects the heat exchanger from corrosion, extending the unit’s lifespan.

  5. Econo Mode: This energy-saving feature automatically adjusts the cooling capacity to match the current load, reducing energy consumption without compromising comfort.

In comparison, OLMO’s units, while still offering reliable performance, may not boast the same level of advanced features and technological innovations as Daikin’s offerings.


In the battle of Daikin vs. OLMO, Daikin emerges as the clear winner, offering superior efficiency, lower noise levels, longer warranty coverage, and more flexible installation options. Additionally, Daikin’s advanced features and cutting-edge technology set it apart from the competition, making it a top choice for those seeking a high-performance, energy-efficient, and reliable air conditioning system.

However, it’s important to consider your specific needs, budget, and the availability of professional installation services in your area before making a final decision. Carefully weigh the pros and cons of each brand to ensure you make the best choice for your home or business.

Remember, when it comes to HVAC systems, proper installation and maintenance are crucial for optimal performance and longevity. Consult with a licensed HVAC professional to ensure your air conditioning system is installed and maintained according to the manufacturer’s specifications.
