What is an Evaporator?

The evaporator is a critical component in your car’s air conditioning system. Located inside the dashboard, its primary function is to absorb heat from the vehicle cabin and transfer that heat to the refrigerant circulating within the system. This absorption of heat causes the refrigerant to evaporate, creating the cooling effect that makes your car comfortable in hot weather.

How Does an Evaporator Work in Your Car?

Heat Absorption & Cooling Effect

Located inside your dashboard, the evaporator contains coils through which cold refrigerant flows. As warm cabin air passes over these coils, the heat is absorbed by the refrigerant, causing it to evaporate. This heat absorption creates the cool air blown into your vehicle.

Refrigerant State Change & System Flow

The evaporator operates at low pressure and temperature, allowing efficient heat absorption. Refrigerant enters as a liquid and exits as low-pressure vapor, then moves to the compressor. It also removes humidity, preventing foggy windows and improving comfort.

Key Evaporator Functions:

✓ Primary Cooling Component:

The main component that creates cold air in your vehicle’s AC system

✓ Humidity Control:

Removes moisture from cabin air, preventing foggy windows

✓ Air Filtration:

Often works with cabin air filters to clean incoming air

✓ Temperature Regulation:

Precisely controls output temperature based on your settings

Frequently Asked Questions

Get answers to common questions about evaporator replacement


Q

How do I know if my car’s evaporator needs replacement?

Common signs include: 1) Weak airflow or no cool air from vents, 2) Musty or mildew smell when AC is on,
3) Water leaking inside the car (usually passenger side), 4) Visible frost on evaporator coils,
5) Unusual noises from dashboard area. If you notice any of these signs, contact us for a free diagnostic check.


Q

Why is evaporator replacement more expensive than other AC repairs?

Evaporator replacement requires more labor because it’s located inside the dashboard, often requiring partial
dashboard disassembly. The evaporator itself is a precision component, and the repair must include complete
system flush, refrigerant recovery, and vacuum testing. Despite the complexity, our mobile service saves you
money by eliminating towing costs and shop fees.


Q

How long does evaporator replacement take?

Most evaporator replacements take 4-6 hours, depending on the vehicle make and model. European luxury vehicles
or those with complex dashboard designs may take longer. We provide same-day service for most vehicles and
can complete the job at your home or workplace in Canberra. We’ll give you an accurate time estimate after
inspection.


Q

Can a clogged evaporator be cleaned instead of replaced?

In some cases, yes. If the issue is surface contamination, we can perform professional evaporator cleaning
using specialized equipment. However, if there’s physical damage, corrosion, or refrigerant leaks, replacement
is necessary. We always start with a free diagnostic check to determine the best solution. Cleaning may extend
evaporator life by 1-2 years in some cases.


Q

What’s included in your evaporator replacement service?

Our complete service includes: 1) Free diagnostic testing, 2) Professional dashboard disassembly/reassembly,
3) OEM or high-quality aftermarket evaporator, 4) Complete AC system flush, 5) New receiver-dryer installation,
6) Refrigerant recharge with correct amount and type, 7) System vacuum test and leak detection,
8) Performance testing, 9) 12-month warranty on parts and labor, 10) Clean-up and disposal of old parts.


Q

Should I replace other AC components when replacing the evaporator?

We strongly recommend replacing the receiver-dryer whenever the evaporator is replaced, as contaminants from
the old evaporator can damage the new one. We also recommend replacing the expansion valve (TXV) and checking
the compressor. During our diagnostic, we’ll inspect all components and advise which replacements will ensure
your new evaporator lasts as long as possible.


Q

Will my car’s warranty be affected by your mobile evaporator replacement?

No. Our certified technicians use OEM-quality parts and follow manufacturer specifications. We provide detailed
service records and our work is backed by a 12-month warranty. Most importantly, proper AC service doesn’t void
new car warranties unless it directly causes damage to other components – which our professional service prevents.


Q

How can I prevent evaporator problems in the future?

Preventative maintenance is key: 1) Run your AC for 10-15 minutes weekly (even in winter) to keep seals lubricated,
2) Replace cabin air filters regularly (every 12-24 months), 3) Get annual AC system checks, 4) Address small leaks
immediately, 5) Have professional cleaning if you notice musty smells, 6) Use quality refrigerants only.
We offer maintenance packages to help extend your AC system’s life.
