New advances in corrosion protection improve HVAC performance and homeowner satisfaction
While corrosion—and the related leaks it produces—isn’t a new challenge in the HVAC industry, it’s becoming more prevalent as environmental changes inside and outside homes create the ideal conditions for it to develop. Corrosion and the elements that cause it can take many forms, but the results are the same— leaks that lead to HVAC system failures, frustrated homeowners and the need for low-margin service calls.
Being prepared for a changing world
More and more, buildings and homes are being tightly constructed with more wall and roof insulation along with improved building practices that minimize air passing in and out of structures. These are well-intentioned changes with plenty of benefits, like cost savings for homeowners. Tighter homes prevent warm air from escaping in winter, and help maintain cool indoor temperatures during warm weather.
But that same “sealed tight” environment also means that whatever is trapped in the house, stays there. Many paints and solvents, aerosols and cleaners, even carpets and upholstery are utilizing materials that off-gas Volatile Organic Compounds (VOCs). In addition to harming a home’s indoor air quality, they can combine with moisture to create organic acids that cause corrosion in HVAC evaporator coils, leading to disruptive and expensive leaks and failures.
Outside the home, salt air and a mix of pollutants can create an environment that enhances the threat of corrosion. These hazards present a significant risk to the longevity of traditional evaporator coils which are made more vulnerable to leaks and system failure.
As HVAC professionals continue to face these challenges, finding an ideal corrosion mitigation option is essential. A good start is considering units with updated coils that have undergone rigorous testing designed to simulate in-home corrosive effects. Your business’ reputation relies on the quality of the equipment you recommend, so be sure you’re working with a proven solution designed to reduce leaks through long-term corrosion resistance.
Some manufacturers have experimented with novel materials and designs, creating a learning curve that requires expensive and time-consuming retraining for install and service technicians. The ideal approach minimizes additional training. Since most HVAC residential equipment uses a traditional tube-and-fin design along with copper stub-outs, look for the same configuration to reduce install times and callbacks. And in order to take advantage of the most opportunities possible, seek out options that help equally protect coils from indoor and outdoor threats with a broad product portfolio. There’s been a lot of focus over the past several years on indoor coil corrosion, but as environmental threats add up and weather becomes more volatile, consider systems that deliver improved corrosion resistance on equipment operating indoors and outside.
At Allied Air, we’ve spent over a decade developing new and proven ways to combat corrosion and supporting HVAC professionals to better serve their markets. With next-generation coils and technology built into all aspects of our systems, we’re helping advance the latest and most effective HVAC solutions that deliver the longevity and peace of mind today’s customers expect.
