OUR GOAL

Professional Installation for Your New Home or BTO Unit

Aircon installation is not just mounting a unit. The quality of piping, drainage slope, placement, and final testing affects cooling performance and long-term reliability. Decom Aircon provides structured aircon installation for BTO homes and new properties, with practical package options and add-ons to match your layout and usage needs.

If you are deciding between system types, we can guide you on inverter aircon suitability, room usage, and installation considerations. We also support popular brands including Mitsubishi aircon and Panasonic aircon, depending on your preferred setup and budget.

Why Installation Quality Matters

A poorly installed system will leak water and lose gas within the first year, ruining your new renovation. This is why the quality of your aircon trunking the pipes and conduits connecting the machines is just as important as the brand of the aircon itself. We use premium, thick insulation to prevent condensation from dripping onto your newly painted walls.

Choosing the Right Brand

We do not push brands with high profit margins; we recommend systems proven to survive our local climate. Our technicians frequently install highly reliable units like a Mitsubishi aircon or Panasonic aircon because parts are easily available. For maximum energy efficiency, we almost always advise homeowners to select a modern inverter aircon.

Our Aircon Installation Process

When you book an aircon installation with Decom, the price covers the indoor blowers, the outdoor unit, and the full labor required to mount them safely. We handle the heavy lifting and ensure all brackets are securely fastened to HDB or BCA standards.

Crucially, our packages include the routing and concealment of your aircon trunking. We measure the most efficient path for the copper pipes and drainage lines, ensuring they blend cleanly into your home’s layout.

Finally, we manage the safe placement of the air conditioner compressor. We ensure it sits on proper vibration-damping mounts on your external ledge, preventing annoying rattling noises from vibrating through your bedroom walls at night.

Aircon Brands We Install

OFFICIAL SERVICE PARTNER FOR ALL MAJOR BRANDS

01 Daikin

02 Mitsubishi Electric

03 Panasonic

04 Midea

05 LG

06 Haier

07 Toshiba

We supply and install the most trusted residential brands in the market. A Mitsubishi aircon is renowned for its durability and extremely quiet operation, making it a favorite for master bedrooms. Alternatively, a Panasonic aircon offers excellent air purification features and highly efficient cooling profiles.

We strongly recommend choosing an inverter aircon technology regardless of brand, as it intelligently adjusts compressor speeds to save massive amounts of electricity in Singapore's hot climate. Finally, for specific older HDB layouts or rental rooms without proper ledge space, a window aircon remains a viable, budget-friendly alternative.

BTO vs Condo vs Landed Installation

apartment BTO Flats

For new homeowners, our BTO air con installation in Singapore involves planning the trunking routes before your carpentry goes up. We understand standard HDB floor plans intimately, allowing us to finish the piping quickly and neatly.

domain Condominiums

Condo installations often face strict management rules regarding working hours and exterior aesthetics. We ensure your inverter aircon is installed cleanly while strictly adhering to your MCST guidelines.

foundation Landed Homes

Landed properties require a larger scale of work, often involving multi-split systems or commercial-grade ducting. We carefully plan the heavy air conditioner compressor placements on roofs or in backyards to maintain your property’s exterior appeal.

Outdoor Compressor Placement

A common anxiety for new BTO owners is where the heavy machinery goes. The air conditioner compressor must be placed on the designated reinforced ledge outside your window. We ensure it has adequate breathing room, as restricted airflow will cause the unit to overheat and consume excessive power.

Standard #1

BCA-Certified Brackets used for all ledge-less units.

Standard #2

Minimum 600mm front clearance for heat dissipation.

Frequently Asked Questions

When is the best time to install my BTO aircon during renovation? expand_more

For HDB BTO flats, the best time to install the aircon is during the early renovation phase, specifically before any false ceiling or carpentry work begins. This allows our technicians to run the copper pipes and drainage pipes cleanly and conceal them.

What type of piping and insulation material do you use? expand_more

We use premium Class 1 copper pipes (usually G22 or G23 gauge) and 1/2-inch Class 0 Armaflex insulation to prevent condensation and pipe sweating, ensuring your installation lasts for years.

Can I install a System 4 or System 3 aircon in my BTO flat? expand_more

Most modern HDB BTO flats have a designated aircon ledge designed to fit one large multi-split outdoor compressor. A System 4 (4 indoor units connected to 1 outdoor compressor) is the most common choice for 4-room and 5-room flats.

What warranty do you provide on the aircon installation? expand_more

We provide a 1-year installation warranty against water leaks and gas leaks, in addition to the manufacturer’s product warranty on the compressor and indoor units.

Do you supply and install HDB-approved compressor brackets? expand_more

Yes, HDB BTO flats come with built-in aircon ledges. If your ledge is narrow or requires a custom bracket, our BCSS-certified technicians can supply and install HDB-approved stainless steel brackets.

How long does the BTO aircon installation process take? expand_more

A standard BTO installation is typically done in two phases: running the piping/trunking during the early renovation phase (approx. 4-6 hours), and mounting/commissioning the units after painting is complete (approx. 2-3 hours).

Where should I place the outdoor air conditioner compressor? expand_more

Your outdoor air conditioner compressor must be mounted on the HDB-approved external ledge using sturdy brackets. We ensure it is placed with enough clearance from the wall so that hot air can dissipate quickly, keeping the system efficient and safe.
