Is your aircon no longer cooling like it used to? Does the air smell stale or musty when you switch it on? These are common signs that your unit needs more than a basic clean. Over time, dirt, mould, and dust collect inside, blocking airflow and reducing cooling.
A regular service helps, but it can’t reach the hidden parts deep within the system. That’s where an aircon servicing chemical wash comes in. This deep clean clears thick build-up, restores strong airflow, and brings back that fresh, cool breeze you need.
It’s the best way to keep your aircon running well and your space comfortable. In this guide, we’ll explain how a chemical wash works, when you need one, and what the chemical wash aircon cost looks like in the long run.
What Is an Aircon Servicing Chemical Wash?
A regular service only cleans surface parts. It clears filters, wipes the outer casing, and checks the cooling gas. That helps for a while, but dust, mould, and grime build up inside the unit over time.
An aircon servicing chemical wash is deeper. It takes the unit apart and cleans each part using a chemical solution. This clears thick dirt from the coil, fan, and drainage tray. It also removes mould and bacteria that cause smells.
Why Your Aircon Might Need a Chemical Wash
Here are signs your aircon needs more than a light clean:
- Weak airflow
- Warm air instead of cool
- Water leaks from the unit
- Strange or musty smells
- Noise when the unit is on
These problems happen when dirt blocks key parts inside. A deep clean can help restore normal flow and fix these issues.
What Happens During a Chemical Wash?
A trained technician comes to your home or office. They do the following:
1. Take the Aircon Apart
They remove the fan coil, filters, and other inner parts.
2. Soak the Parts in a Cleaning Solution
Each part goes into a chemical bath to break down thick dirt and grime. This helps clear mould, sticky residue, and trapped dust.
3. Rinse the Parts
The parts are rinsed with clean water. This step is key. It clears any leftover solution so the unit stays safe and clean.
4. Reassemble and Test
The technician puts the unit back together. They test for good airflow, cold air, and clean operation.
This full cleaning helps to restore airflow, remove smells, and boost cooling speed.
How Often Should You Get a Chemical Wash?
This depends on how often you use the aircon:
- Daily use: Every 6 months
- Weekly use: Once a year
- Light use: Every 18 months
If you live in a dusty place or have pets, you may need it more often. Mould and blocked coils grow fast in damp spaces.
Restore Airflow and Cooling Power
A common reason people book a chemical wash is to restore airflow. When coils or fans are blocked, the air cannot move through. This makes the room take longer to cool.
After a chemical wash, the unit:
- Pushes out stronger air
- Cools faster
- Runs quieter
- Stops dripping
- Uses less power
You can feel the change straight away. The room cools better and smells clean.
Chemical Wash Aircon Cost – What Should You Expect?
Now let’s talk about the chemical wash aircon cost.
Prices range varies per unit. The cost depends on your air conditioning type and size. Some bigger or older systems may cost more.
It may seem high if you compare it to a basic service, which costs about £30 to £50. But a chemical wash gives better results:
- It helps your air conditioner last longer
- It stops major faults
- It clears deep dirt and mould
- It improves the air you breathe
This makes the cost worth it, as you avoid big repairs later.
Is It Safe to Do It Yourself?
No, this is not a job for most people. You must open the unit, soak the parts, rinse them well, and reassemble it without breaking anything. A mistake could damage the motor or cause leaks.
Always book a trained professional for a chemical wash. They will have the right tools and cleaning solution to do the job right.
What to Ask Before You Book
Before you go ahead with an air conditioner servicing chemical wash, it’s good to ask a few simple questions. This helps make sure the job is done right.
Will they open the whole unit?
The technician should take the unit apart so they can clean inside where the dust and mould build up.
Will they soak and rinse the parts?
Ask if the parts will be soaked in a cleaning mix and then rinsed well. This clears thick dirt and keeps the unit safe.
What cleaning mix will they use?
The solution should be safe for your aircon and should not harm metal or plastic parts.
Will they check the ga?s
Gas levels need to be right for the unit to cool well. This should be part of the service.
Do they offer a guarantee
A guarantee gives you peace of mind if anything goes wrong later.
Getting clear answers helps you choose the right service.
When Is the Best Time to Book a Chemical Wash?
Book your wash:
- Before hot weather begins
- After long periods of use
- If your aircon has not been cleaned for over a year
This gets the unit ready for the warm months ahead and avoids breakdowns when you need it most.
Final Thoughts
An aircon servicing chemical wash is not just about clean parts—it’s about comfort. It brings back the cold air, clears smells, and helps your system run better. You’ll notice the change at once.
Though the chemical wash aircon cost is higher than a basic service, it offers more value. It protects your unit, lowers repair costs, and keeps your space cool and fresh.
If your aircon has weak flow, smells bad, or leaks water, it may be time for a chemical wash. This small step can give you many cool, trouble-free months.
Your aircon deserves care. A clean system gives you peace of mind and fresh air again.
