Ducted A/C is available in the Philippines if you are prepared to pay the costs of these beasts as opposed to reduced installation and running costs of split systems single and multiple heads, wall/window mounts for smaller areas. My neighbour up the road has ducted A/C throughout his mansion on the beach, PHP 1.5M then a further 1.5M for a solar system to negate the running costs through the day. Up to 3 million pesos to cool your house? Some people have too much money and his electricity bill is still more than ours.yeah you are right Gary D. Only the split units. I have never seen a house with ac duct work installed there. I have been to a lot of new subdivisions like Camella homes and never saw central units like in the USA. Also, I am sure the cost is sky rocketing to cool whole house there.
Even if I ran all our A/C units, wall and split day in day out my bill would/could be 10K per month, that's 120K per year, let's say 150K per year, do the sums for 20 years on. Cool only what you need, reduce purchase and running costs.
The other thing I will add is for the last 8 or 9 years being back and forward here is I realised I was a soft c*ck and needed to acclimatise, Already from a semi tropical locale in Oz am manning up.
