Question 1

Does coating affect HVAC performance?

Accepted Answer

No, properly applied coatings improve performance by maintaining clean surfaces and optimal airflow. The coating is thin enough not to impede heat transfer while providing robust protection against corrosion.

Question 2

How long does coating last?

Accepted Answer

With proper maintenance, coatings typically last 5-10 years depending on environmental conditions. Coastal and industrial environments may require more frequent reapplication, but this is still far more cost-effective than equipment replacement.

Question 3

Can you coat old units?

Accepted Answer

Yes, we can coat both new and existing systems. For older units, we first clean and prepare the coils to remove existing corrosion and debris before application. This process can restore performance and extend the life of aging equipment significantly.

Question 4

Is it worth coating existing systems?

Accepted Answer

Absolutely. Coating existing systems is far more cost-effective than replacement. It can extend equipment life by 5-10 years and dramatically reduce maintenance costs. The coating investment is typically 5-10% of replacement costs.

Question 5

What's the typical cost?

Accepted Answer

Costs vary based on system size, accessibility, and environmental conditions. Generally, coating costs 5-10% of replacement costs. For example, protecting a $20,000 system might cost $1,500-$2,000. Contact us for a detailed quote based on your specific requirements.

Question 6

Is there a warranty?

Accepted Answer

Yes, we provide warranties on our coating work. Warranty terms depend on the coating type and environmental conditions. We also offer maintenance programs to maximise coating lifespan and system reliability.

Question 7

Can I claim coating as a maintenance expense?

Accepted Answer

Coating is generally considered a maintenance expense rather than a capital improvement. However, tax treatment depends on your specific circumstances. We recommend consulting your accountant for advice on your situation.

Question 8

What's the downtime?

Accepted Answer

Most applications can be completed in 1-2 days with minimal disruption. We work around your schedule to minimise impact on operations. For commercial buildings, we can often work during off-hours or weekends.

Question 9

What prep is required?

Accepted Answer

We handle all preparation including cleaning, surface treatment, and masking. You just need to provide access to the equipment. For rooftop units, safe access to the roof is required. We coordinate with building management to ensure smooth operations.

Question 10

Do you work on site or take equipment away?

Accepted Answer

We primarily work on site for installed HVAC systems. This minimises disruption and costs. For smaller components or new installations, workshop application may be possible. We assess the best approach during the initial inspection.

Question 11

Can you work around our operations?

Accepted Answer

Yes, we understand commercial buildings need to maintain operations. We schedule work to minimise disruption, can work in stages, and coordinate with building management to ensure tenant comfort is maintained throughout the process.

Question 12

Does it void manufacturer warranty?

Accepted Answer

Our coatings do not typically void manufacturer warranties. We use approved materials and methods that are compatible with equipment specifications. If you have concerns about a specific warranty, we recommend checking with your manufacturer.

Question 13

What prep is required?

Accepted Answer

Professional cleaning is essential for proper coating adhesion. We use specialised cleaning methods to remove dirt, debris, existing corrosion, and contaminants. The surface is then prepared to ensure optimal coating performance.

Question 14

Is the coating chemical resistant?

Accepted Answer

Yes, our coatings resist most industrial chemicals, pollutants, and cleaning agents. Specific chemical resistance depends on the coating type and application. We select appropriate coatings based on your environment and exposure conditions.

Question 15

Can coated systems be cleaned?

Accepted Answer

Yes, coated systems can be cleaned using standard HVAC maintenance procedures. The coating actually makes cleaning easier by preventing contaminants from bonding to coil surfaces. Regular maintenance extends both coating and equipment life.

Question 16

Do coastal properties really need coating?

Accepted Answer

Yes, absolutely. Salt air is extremely corrosive to HVAC equipment. Properties within 5km of the ocean can experience coil failure in 2-4 years without protection. Coating extends life to 10+ years, making it essential for coastal properties.

Question 17

What about industrial environments?

Accepted Answer

Industrial environments often have chemical pollutants, dust, and contaminants that accelerate corrosion. Our coatings provide a barrier against these factors, extending equipment life and reducing maintenance in manufacturing, food processing, and other industrial applications.

Question 18

Is coating suitable for new systems?

Accepted Answer

Yes, coating new systems is ideal. Applying protection from day one maximises equipment lifespan and provides the best return on investment. Many commercial clients now specify coating for all new HVAC installations.
