“Hate” is maybe too strong; how about “intensely dislike.” Statistics show that 75% of contractors spend over half of their entire marketing budgets in the Yellow Pages. Yet this results in just 13.4% of HVAC sales.
When DST Output decided it needed more space to expand its printing and publishing services for mutual fund companies, it looked in a rather unlikely spot. Instead of choosing an existing building to move into or even vacant land on which to build, DST Output chose to renovate an abandoned railroad roundhouse.
The Partnership for Air-Conditioning, Heating, Refrigeration Accreditation (PAHRA) was introduced over two years ago. The organization aims to set standards by which all HVACR programs can assess themselves. Linn State Technical College’s HVACR program was the first in the nation to align itself with PAHRA’s standards.
Rooftop units have come a long way in recent years. They now contain more sophisticated controls, improved serviceability features, and unique ways to address indoor air quality (IAQ) issues. But even the best-made rooftop can’t keep soldiering on if routine maintenance is not performed regularly.
Is it mold or is it gold? The latest “money-maker” for HVACR contractors may come from testing and remediation of mold and other indoor allergens. But is it worth the time, effort, and expense to become an indoor air quality (IAQ) expert, especially in testing for and remediation of mold?
Compressor hard-start devices are a luxury item for service technicians to use in rectifying a myriad of compressor start problems. The hard-start device can serve as an insurance policy for compressor starts when voltages drop to 90% of rated line conditions.
Rooftop units toil away during the day under hot conditions; consequently, their energy efficiency, as compared with chiller systems for building cooling, is generally much lower. One manufacturer, Calmac Corp., has created the Roofberg® system, which permits conventional rooftop units to be converted to a central chiller system with ice storage.
Have you ever given an excellent presentation and presented the price on your beautifully designed proposal form, only to have them say, “We’re 90% certain we’re going to go with you."
Universal Technical Institute (UTI) has been going strong since 1965. Recently, though, the institute has had to shut down its heating and air conditioning program at two campuses. But it has a few tricks up its sleeve to keep the HVACR program alive and in the minds of prospective students as a one-of-a-kind opportunity.
