HDB, condominium, landed, and commercial properties — one contractor team, written quotes before work starts.
Overview
In Singapore's humidity an air-conditioner works almost every day of the year. Skipping service does not just cost you cooling — it builds mould in the fan barrel, chokes the drainage line, and pushes your electricity bill up long before the unit actually fails.
D&K services, repairs, installs, and relocates split, cassette, and window units for homes and offices island-wide. We tell you what the unit actually needs. If a general service is enough, we will say so rather than upselling a chemical overhaul.
What we cover
Filter and fan cleaning, drainage flushing, coil vacuuming, condenser check, and refrigerant pressure verification on each unit.
For units with mould, weak airflow, or persistent odour — chemical cleaning of the fan barrel, coil, and drain pan to restore output.
Full dismantling of the fan coil for deep cleaning and reassembly, recommended for heavily fouled or long-neglected systems.
Clearing choked condensate lines, re-insulating pipework, correcting gradient, and fixing the dripping that stains ceilings and walls.
Pressure testing to find the actual leak point, repair, then recharging to the manufacturer's specification instead of a blind top-up.
New system installation, unit replacement, trunking, piping, and relocating fan coils or condensers during a renovation.
How it works
Not cold, dripping water, noisy, or smelling musty — each points to a different cause. Tell us and we arrive with the right parts.
We check airflow, temperature differential, gas pressure, drainage, and electrical supply before recommending anything.
You approve the scope and price first. If the unit only needs a general service, we will not sell you an overhaul.
We run the system, confirm the outlet temperature, clean up, and advise a realistic servicing interval for your usage.
For a home used daily, every three months is the usual interval. Heavier use, pets, or dusty environments may need it every two months. Offices and F&B outlets that run all day should be on a monthly or bi-monthly schedule.
The common causes are a dirty filter or coil restricting airflow, low refrigerant from a leak, a faulty capacitor or compressor, or a condenser that cannot dissipate heat. We diagnose on site rather than defaulting to a gas top-up, because topping up a leaking system only buys a few weeks.
A general service cleans filters, the fan, and drainage to maintain a healthy unit. A chemical wash uses cleaning agents on the coil and fan barrel to remove built-up mould and grime — needed when airflow has dropped or there is a musty smell.
Yes. We handle new installations, replacements, piping and trunking, and relocation of fan coils or condensers. We can advise on system sizing so you do not overspend on capacity you will never use.
