Aircon Chemical Overhaul 

In Singapore's tropical climate, air conditioning is essential for comfortable living. But like any machine, your aircon unit needs regular servicing to function efficiently. While general servicing helps with surface-level cleaning, more intensive methods like aircon chemical overhaul are sometimes necessary. If you're wondering whether this type of deep cleaning is worth the investment, LetsCool Aircon and Services in Singapore is here to help you understand the value behind it.

With more than 25 years of experience in the aircon industry, LetsCool has earned a reputation as a trusted and professional aircon service provider. We specialize in aircon chemical overhaul for all major brands and provide transparent, high-quality service across Singapore. View more

What Is an Aircon Chemical Overhaul?

An aircon chemical overhaul is a deep cleaning service where the entire aircon unit is dismantled, and each component is individually cleaned using a chemical solution. Unlike general servicing, this process involves thoroughly cleaning internal parts such as:

  • Evaporator coils



  • Air filters



  • Blower wheels



  • Drainage pipes



  • Fan bearings



  • Thermostat sensors



All parts are cleaned, dried, and reassembled with care. At LetsCool, we also inspect for wear and tear, lubricate moving parts, and test the system for optimal performance after reassembly.

When Do You Need a Chemical Overhaul?

Many customers ask: "Do I really need an aircon chemical overhaul?" The answer depends on your unit's condition. Here are signs that it may be time for one:

Weak or uneven cooling

Unusual noises during operation

Water leakage from the indoor unit

Bad odour or musty smell

Aircon hasn't been serviced in over a year

Frequent need for repairs

In places like Singapore, where aircons often run daily, a chemical overhaul is typically recommended every 1.5 to 2 years, especially if the unit is in heavy use.

Benefits of Aircon Chemical Overhaul

At LetsCool Aircon and Services, we perform chemical overhauls to improve not just cooling performance, but also the overall health of your unit. Here's how our overhaul service delivers value:

1. Restores Cooling Efficiency

Over time, dirt and grime build up inside your unit, blocking airflow and reducing efficiency. A chemical overhaul removes these blockages, restoring your aircon's cooling power.

2. Prevents Major Breakdowns

By cleaning and inspecting each component, we can catch potential issues early—before they result in costly repairs or system failure.

3. Improves Air Quality

Mold and bacteria can accumulate in dirty aircon parts, leading to poor indoor air quality. A chemical overhaul eliminates these harmful contaminants.

4. Extends Unit Lifespan

Regular deep cleaning ensures that components don't wear out prematurely. This helps you avoid replacing your aircon sooner than necessary.

5. Reduces Electricity Bills

A clean, well-maintained aircon doesn't have to work as hard to cool your space. That translates to lower energy consumption and reduced monthly bills.

Is the Price Justified?

Yes—when you consider the long-term benefits, an aircon chemical overhaul offers excellent value for money.

At LetsCool, our chemical overhaul service is affordably priced and includes a 90-day workmanship warranty. We believe in transparent pricing with no hidden charges, so you'll always know what you're paying for.

Typical pricing ranges (as of 2025):

  • 1 Fan Coil Unit: From $90



  • 2–3 Units: Bundle discounts available



  • Commercial/Office Units: Custom quotation based on system type



Considering the potential costs of aircon replacement (often thousands of dollars), spending a few hundred on a chemical overhaul every couple of years is a wise investment.
