After 21 years in the industry, Glenn Bland was in the doldrums. So he shook things up and took an International Ground-Source Heat Pump Association (IGSHPA) geothermal class. “That has brought everything back to life as far as I’m concerned,” he says.
Even the best laid plans sometimes go awry. A geothermal system may not work as originally intended. What do you do if that happens? Fortunately, troubleshooting these systems is straightforward, as is the regular maintenance required.
Rooftop unit manufacturers are responding to the need to control humidity by outfitting their units with a dehumidification component. How each unit removes moisture varies from company to company, but they have a universal goal: to improve the comfort of building occupants by controlling humidity.
When the Doral Costa Office Building was being designed, it didn't really start as a blank slate. That's because the developer knew he didn't want any mechanical equipment inside the building. After looking at the options, it seemed rooftop units would be the best choice.
The Christian Street Court buildings have stunning architectural elements. Preserving their architectural and historical integrity required skill and ingenuity on the part of the HVAC contractor.

It may have been dark and dreary outside, but the atmosphere inside Service Champions' offices was so warm and inviting that it was immediately apparent why the company was The News’ “Best Contractor to Work For” in the West/Pacific region.
In 1992, Advanced Distributor Products (ADP) began manufacturing coils in a section of the Heatcraft OEM coil facility. In 1996, the company moved into a new 325,000-square-foot facility, followed by a 54,000-square-foot addition. One of its coils is the brand-new Healthy Solutions Premium Evaporator Coil.
Is there something else contractors should do besides clean the coils to improve their performance? Are there other steps that can be taken? We’re glad you asked, because several experts offered their opinions concerning what contractors can do to optimize coil performance.
Manufacturers purposely design condenser and evaporator coils to work together in order to provide the best possible cooling for an application. So why would anyone consider replacing one coil and not the other? Why would anyone be tempted to oversize or undersize one component when the other isn’t designed for that capacity?
