A new report from the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) found sales of HVAC equipment increased 29.7 percent in September 2014 compared to the previous year. Roughly 539,628 units were sold, with central air conditioning equipment sales jumping 22.9 percent and air-source heat pumps rising more than 44 percent.

The AHRI report details the latest data available for the HVAC industry, with a large portion of units going toward the commercial sector. The numbers might be indicative of an overall trend toward newer equipment as technology advances and companies grapple with energy costs.

Older models, or HVAC systems with inefficient parts, operate at a much lower capacity while still consuming high levels of electricity necessary for power. By reducing electricity consumption, companies can save money on utility costs – which take up a significant amount of their budgets.

In general, the largest source of energy consumption by commercial buildings as a whole is lighting, while cooling, ventilation and refrigeration are second, third and fourth, respectively, according to the U.S. Energy Information Administration.

In the case of HVAC shipments, much of the concern within the commercial sector is maintaining current HVAC systems instead of replacing the unit as a whole. An entire HVAC unit can be a large expense for companies. However, alternate solutions, like revitalizing individual parts of the unit are more cost-efficient, enabling businesses the opportunity to improve the performance of their HVAC systems.

Repairing HVAC units
The most effective way to enhance the main controls of an HVAC system – airflow, temperature and quality – is to identify the specific parts that are working under capacity. In many cases, this comes down to coils.

Chilled water coils, evaporator coils and other vital components commonly suffer deterioration without proper protective measures in place. This can lead to cratering, cracks and leaks within an HVAC system, causing a unit to fail prematurely.

At Rahn Industries, coils can be refurbished and brought back to life through the innovative use of coil coatings. By locating the problem area, whether it be corrosion, buildup or loss of heat transfer, Rahn can apply durable, long-lasting coatings overtop the coils, creating a complete seal that prevents future damage.

Once in action, coated coils perform like new, with a much higher tolerance level against harmful contaminants.

Rahn Industries has a full lineup of spray and immersion (dip)/ Bake protective coatings to meet your needs.
