What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.

Factors to Consider


The price of your unit will depend on the type of unit you're considering to install, the model and brand of the air conditioner, and its cooling power. The more complex and efficient the system, the more expensive it will be on a general basis. Expect a portable air conditioner for 500 sq ft of space to cost around $300 to $800 for the unit alone.

Type of Air Conditioner

There are multiple types of air conditioners that can be used in 500 square feet of space. From the standard window units to the more complex mini split systems, you can find a suitable air conditioner to install in your area.

Among the types of air conditioners you can opt to install is the portable air conditioner, as these units span in cooling capacity, are easy to install, and require no drilling, mounting, or cutting. Portable air conditioners are ideal for rented homes and small spaces, and come in a variety of energy efficient, powerful, and quiet units.

Cooling Power

The size of your space matters when it comes to choosing portable air conditioning units with efficient cooling power. A 500-square foot space will need at least 10,000 BTU of cooling power, but 12,000 and 14,000 BTU will work just as well.

For reference, a portable air conditioner typically has 5,000 BTU, so you will need double the cooling efficiency to be able to create cool air for your space. Multiple units can work as well, as these circulate air in different zones around the space.

Energy Efficiency

Consider the energy consumption of your AC unit as well. A portable AC unit uses less energy than centralized air conditioning systems and mini splits, while more advanced models typically have better energy efficiency than previous models of the same unit. Check the SEER rating, energy efficiency, and wattage of the air conditioner before purchasing one.


The frequency of maintenance needed to upkeep your unit is another factor to consider as it can be troublesome to keep cleaning, repairing, and maintaining the unit. Most portable air conditioning units and mini split systems are low maintenance, and rarely require cleaning. However, some models may require more maintenance than others.

Maintaining your unit can be more convenient with our aircon services at Luce Aircon. From centralized ducted air conditioners to portable air conditioners, our team can make sure your units are working fine!
