Corrosion is slowly killing your HVAC coils, and the results can be an expensive re-installation. The best way to prevent this is to take precautionary measures, one of which is coil coating.
But here’s the thing: Not all coating contractors are the same, and hiring the wrong one can incur more problems than solutions. Here’s a detailed guide explaining how you can choose the right HVAC coil protection contractor for your needs:
Understand Different Coatings
HVAC coil protection is the process of applying a protective layer on integral HVAC coils, mainly condenser, evaporator, and finned tube coils. The coating can also be applied to other metal components, such as fans, blowers, ductwork, and louvers. That said, there are different coating materials and methods, each with different use cases.
Types of coating materials include:
Epoxy – excellent adhesion and corrosion resistance
Polyurethane – flexible, thin, and inexpensive
Fluoropolymer – excellent chemical resistance
Blygold – chemical and UV resistance
Knowing the different types of coil protection materials can help streamline the process, making sure you end up working with the contractor that specializes in that area.
Assess the Extent of Services Offered
Do a thorough internet search and shortlist contractors based on the services they offer. As hinted earlier, coating methods differ and provide varying results. Reputable contractors specialize in all coating methods, including:
Spray Coating: A spray gun is used to evenly distribute the coating material on the coils. This can be done on-site or at a factory.
Dip Coating: It involves submerging HVAC coils in a mixture of coating materials. Dip coating is especially useful for large-scale industrial and commercial equipment.
Electroplating: E-coating involves applying coating materials to HVAC coils using electrical current. The result is excellent adhesion and corrosion resistance.
Work with a contractor that offers more than just installation. They must provide maintenance tips and ongoing services to ensure the longevity of the treatment.
Assess Reviews and Reputation
Hiring a reliable HVAC coil coating contractor can make a world of difference. Take a deep dive into customer reviews. Analyze what other people have said about the contractor’s services and workmanship.
The last thing you want is to work with a contractor that offers inefficient services, leading to frequent repairs.
Consider Licensing and Certifications
Any contractor that offers industrial and commercial maintenance services must adhere to safety guidelines and regulations. Look for certificates like:
- EPA 608 (for refrigerant handling)
- NATE (North American Technician Excellence)
Make sure the contractor follows any local regulations. This will save you from future costs.
Assess Transparency
HVAC coil coating can become pretty expensive if you don’t oversee the costs. Before finalizing, ask the contractor to give you a detailed estimate, including:
- Product costs
- Installation costs
- Timelines
- Warranty information
Watch out for any additional and undisclosed fees to avoid surprises later on.
Compare Costs
Lastly, get quotes from numerous contractors and compare. Keep in mind the services offered, timeline, warranty, and reviews. A thorough comparison will allow you to make an informed decision.
