Moisture in building envelopes can have serious consequences. For example, moisture in insulation reduces its insulating capability, causing heating and/or cooling losses and wasting energy. Moisture can also cause structural deterioration and foster mold growth. Thermal imaging is well suited to identifying wet spots.
In this troubleshooting situation, we have a customer who has called to say that their 12,000 Btu through-the-wall unit is “blowing cool air even though it’s set for heat.” The unit is a heat pump with a three-speed motor. It operates on 240 vac.
Thousands of commercial and industrial buildings each year are damaged by unforeseen disaster. When damage occurs, it is essential to take immediate action to stabilize the loss and mitigate damage. Doing so will maximize recovery of all contents, minimize replacement costs, preserve good IAQ, and control mold risks.
The dispatcher called Bob and sent him to a job that really sounded like a problem. There had been a hard rain and a customer had a condensing unit that had been under water that morning due to high water from a creek behind his house. The owners were on a fixed income and wanted to get the repair at the best possible price.
Smart HVAC equipment that recognizes when it is failing or has failed, or when conditions have drifted outside its optimum range, could save substantial amounts of energy if the equipment sent useful information to the building owner or contractor. This is referred to as automated fault detection and diagnostics (FDD).
It’s the bane of many managers’ jobs - the preventable accident. In order to instill a sense of responsibility in employees, employers may consider charging workers a deductible after they have had a preventable accident. However, before instituting a policy about charging deductibles, there are many things to consider.
While many students associate the beginning of a school year with the end of summer, outside Texas temperatures suggest otherwise. To combat triple-digit August heat, school districts across the state recently tapped HTS Texas to supply energy-efficient, state-of-the-art cooling systems just in time for students’ arrival.
While synchronous drives do have many industrial applications, they are generally not accepted as the best option for HVAC equipment. Virtually no OEM uses or recommends synchronous drives due to cost, noise and vibration, structural design concerns, and reliable availability of replacement components.
Fire and smoke dampers are a proven and effective way to protect duct and air-transfer openings in walls, barriers, partitions, corridors, and shafts. This article includes the basic testing, installation, and maintenance requirements for life safety dampers.
What do Lehman Brothers, AIG, Merrill Lynch, Washington Mutual Savings, Arthur Andersen, Starbucks, and Toyota all have in common? All went gunning for business growth but instead ended up with self-inflicted wounds. Each of these companies pursued the wrong kind of growth for the wrong reasons.
