Now that we’ve seen out the hottest months of the year, AC units are going on sale! If you looking to choose a new AC unit for your home there are a few options to choose from. You might be surprised to learn that you don’t need to invest a large sum for comfort in the summer months.

Central Unit

If you want to keep every nook and cranny of your home cool over summer, you’ll want a central unit.

The main barrier to people considering this type of AC is the cost. It will set you back between BD$4000 – over 10 000 plus installation costs of between BD$1000 – 3000. It all depends on the size of your house, and the ease of installing the ductwork.

It’s also worth bearing in mind that AC units, ducts and vents will need servicing and repairs, so buying a higher quality brand may pay off in the long run.

Despite the hefty initial investment, central units tend to be the most efficient of all types, and they’re the most discreet. The not-so-attractive Dalek-style main unit can be installed outside, leaving only a simple sleek vent in each room.

Split Wall AC

Choose a split wall AC unit if you’re looking to cool a large room or a couple of rooms (with doors open).

On average a Split Wall AC Unit and installation cost comes to around BD$5000, but it can cost under $2000 depending on brands and the size of the space you want conditioning.

Like central unit AC, split wall ACs are sleek and quiet. A benefit of a split wall unit is that it doesn’t necessitate complicated ductwork and it easier and cheaper to service.

As with a central unit, it’s advisable to service your split wall AC unit each year.


If you’re living in rented accommodation and want to avoid installation costs, you might want to choose a portable AC unit for cooling a single room in the house. Even the best brands come at just a fraction of the price at around BD$500. All you need to do is ensure the duct points out of the window to allow for an exchange of air.

There are a few disadvantages. Primarily the sound. If your white noise is an issue for you, you’re better off installing an overhead fan. The 56-decibel hum and occasional clunk of a portable AC unit might prove to be an annoyance for you.

They’re also quite bulky. Don’t let the name dupe you – if you’re thinking of moving your portable unit from room to room, it’s not impossible, but it is quite a workout. Large and heavy, even though designs are improving, there’s no escaping from the fact that portable AC units still aren’t exactly an addition to your interior design.

Window Unit

Like the portable unit, a window unit is a great option for cooling a single room. Although they’re similarly priced to a portable unit, they’re not as versatile in that you have to place them in your window, obstructing light and your view outside. Noise is also an issue.


Whichever type of AC unit you choose, make sure that it’s appropriate for the size of the area that you want to cool. Each model will have a recommended square meterage. If you’re cooling a conservatory, you’ll need to look for a model which can cool double the square meterage. For example, if your conservatory is 12m2, choose an AC unit that can cool at least 24m2.

A final note. Make sure that your AC unit is serviced annually. Servicing your AC will ensure that it runs more efficiently and can survive the next summer! Left unserviced, an AC unit can grow bacteria and it can throw a year’s worth of dust back into the air, causing asthma and other allergies. We hope these tips help to keep you cool for years to come.
