Service Comparison

Non-Toxic Aircon Servicing vs Chemical Wash — Singapore Comparison

A $50 chemical wash and a $90 non-toxic hygiene service look identical from outside the front cover. They are not the same job. The chemicals used, the surfaces actually treated, and what remains on the unit afterward are different in ways that matter for mould recurrence and for family health.

What a $50 chemical wash typically includes

Detergent + diluted acid solution sprayed on filters and visible evaporator face. Pressure-washed off with the front cover off. Drip pan rinsed. Time on site: 25–40 minutes per unit. The acid removes scale and surface stains but doesn't penetrate the blower wheel or drainage line. No residual antimicrobial — mould regrows within 30–60 days.

What our $90 non-toxic hygiene service includes

Step 1 — non-corrosive cleaning solution applied to all surfaces. Step 2 — steam treatment of evaporator fins AND blower wheel (this is the part that matters). Step 3 — drip pan + drainage line flush. Step 4 — safe antimicrobial coating applied to treated surfaces. Time on site: 60–90 minutes per unit. 90-day no-regrowth warranty.

Why acidic chemicals are a problem in Singapore

Aluminium evaporator fins are thin (0.1 mm). Repeated acidic exposure causes pitting and eventually leaks. We see 5-year-old units with chemical-wash damage that need full evaporator replacement at $400–600/unit. Non-acidic cleaning preserves the unit's lifespan.

Family-safety comparison

Chemical wash: residual acid smell for 2–4 hours, room should be vacated. Aerosolised acidic mist during cleaning is a respiratory irritant. Non-toxic hygiene: food-grade-equivalent solution, no acidic smell, safe for children and pets within 30 minutes of completion.

Cost-per-mould-free-month

Chemical wash: $50 every 60 days (or mould returns) = $25/mould-free-month. Non-toxic hygiene: $90 every 90 days = $30/mould-free-month, plus no acid damage to the unit. The marginal $5/month buys family safety + unit longevity.

Frequently Asked Questions

Are all 'chemical washes' equally damaging?

No — quality varies. Some vendors use mild detergents; others use strong acids. There's no way for a homeowner to know without asking for the SDS (safety data sheet). We publish ours on request.

Can you do steam-only cleaning without any chemicals?

For mild cases, yes. For established biofilm we still need a non-toxic cleaning solution to lift the colony — steam alone removes organic matter but doesn't kill all spores. The combination is what works.

How many units can you service in a single visit?

Most Singapore homes have 2–4 units. We service them in sequence; typical 3-unit home takes 3 hours. Minimum charge equivalent to 1 unit ($90).
