Step 1 — Kakasya Ba?

Room Sizing Guide

Forget complex math. Use this simple Horsepower (HP) cheat sheet based on your room size. And remember: if your room is on the top floor or faces the afternoon sun (West-facing), go up by 0.5 HP.

Room Area (sqm)	Common Room Type	Recommended HP
Up to 11 sqm	Small Bedroom / Maid's Room	0.5 HP
12 – 17 sqm	Standard Bedroom / Small Condo	0.75 HP
18 – 22 sqm	Master Bedroom / Studio Unit	1.0 HP
23 – 27 sqm	Small Living Room / Big Condo	1.5 HP
28 – 40 sqm	Large Living Room / Small Office	2.0 HP

Step 2

Window Type vs. Split Type

Your installation situation and budget are the deciding factors here.

Win dow

Window Type

Best for renters and budget-conscious buyers. Cheaper to buy, easier to clean (DIY-friendly), and no messy copper pipes — but generally noisier and requires a dedicated hole in the wall.

Budget-Friendly

Split

Split Type

Best for quiet bedrooms and modern condos. Very quiet (the noisy compressor stays outside), looks sosyal, and cools rooms faster — but costs more upfront and needs professional installation.

The Inverter Decision — Is It Worth It?

In the Philippines, electricity is expensive — so the answer is almost always YES. It is only truly sulit if you use the aircon for 8 hours or more per day.

Non Inv.

Non-Inverter

Cheaper to buy upfront. But your bill will spike because the motor turns full-on and full-off repeatedly throughout the day — very inefficient for long use.

Inv erter

Inverter

Costs more upfront but saves 30% to 60% on your electricity bill by running the motor at variable speeds instead of constantly cycling on and off.

Pro Tips

Tips for the Smart Pinoy Buyer

These local insights will help you get more out of your aircon and keep your Meralco bill as low as possible.

Check for Blue Fin or Gold Fin

Living near the coast or in a humid area? Look for this anti-corrosive coating on the coils to prevent rust and extend your unit's life by years.

The 25°C Magic

Setting your aircon to 25°C is the sweet spot. Every degree lower adds about 5–7% to your monthly Meralco bill.

Fan Sandwich

Place a small electric fan on the opposite side of the room. It circulates cold air faster so your aircon doesn't have to work as hard.

Look for 5-Star CSPF

Check the yellow energy label for the CSPF rating. In 2026, aim for 5.0 or higher for maximum tipid on your monthly electricity bill.

Maintain the Alaga

Wash plastic filters every 2 weeks to keep airflow smooth. Schedule a professional bomba (pressure wash) every 6 months to maintain peak performance.

Before You Buy

Quick Checklist

Run through these four checks before finalizing your purchase to avoid costly mistakes.

📐

Measure the Room

Do not guess. Measure the actual floor area in sqm and match it to the HP guide above. An undersized unit will never cool the room properly.

🧱

Check Your Wall

Is there already a hole for a window type, or will this be a new split-type install? This affects installation cost and timeline significantly.

🟠

Check the Meralco Orange Tag

Look for the estimated cost per hour on the orange energy tag. This gives you a real picture of your monthly operating cost before you commit.

📋

Check the Warranty

Specifically check the compressor warranty — this is the most expensive part to replace. A 5-year or longer compressor warranty is the industry standard to look for.
