Should I Buy a New AC or Upgrade the Old One?
Before spending money, ask yourself a simple question: is your current unit worth fixing, or is it time to move on? Here is a quick way to decide:| Situation | Best Move |
| AC is below 7 years old and needs minor repairs. | Repair it, as it is cost-effective. |
| AC is 10 years old and breaks down frequently. | Replace it, as you will also save on electricity bills. |
| Your electricity bill keeps rising. | Replace with an inverter or 5-star rated unit. |
| AC struggles to cool the room even when running all day. | Check sizing first, then consider replacement. |
| You are moving into a new home or villa. | Installing a new AC is the wiser investment. |
Types of AC Units Available in Dubai
Dubai’s residential and commercial market offers several types of AC units. Knowing the difference helps you avoid an expensive mistake.Split AC
The most popular choice for Dubai homes. It consists of a single indoor and single outdoor unit. It is quiet, energy-efficient, and ideal for individual rooms.Ducted (Central) AC
Best suited for villas and large apartments. It cools the entire home through a network of ducts, maintaining a uniform temperature throughout.Cassette AC
Ceiling-mounted and commonly found in commercial spaces. It distributes air in four directions, making it well suited for large open rooms.Window AC
An older technology that is less efficient, but affordable for small spaces or temporary use.Portable AC
Easy to move around with no installation required. Useful for minor spaces or as a backup unit.Getting the Right Size AC for Your Space
Buying the wrong size is one of the most common and costly mistakes in Dubai. An undersized unit runs all day without cooling properly, while an oversized unit short-cycles, wastes energy, and leaves behind excess humidity. The general rule is that one ton (12,000 BTU) of cooling capacity is needed for every 500 sq. ft. of space in Dubai’s climate. Always size up if the room gets direct sunlight or has high ceilings.| Room Size | Recommended Capacity |
| Up to 150 sq. ft. | 1 Ton (12,000 BTU) |
| 150 to 250 sq. ft. | 1.5 Ton (18,000 BTU) |
| 250 to 400 sq. ft. | 2 Ton (24,000 BTU) |
| 400 to 600 sq. ft. | 2.5 to 3 Ton (30,000 to 36,000 BTU) |
| 600+ sq. ft. or Villa | Ducted system recommended |
