First, a bit of history… This facility, a small office complex, was built a little more than a decade ago, and the required carbon monoxide safety monitor in the equipment room was disabled at the beginning of the first heating season because there was an ongoing problem with it being activated from time to time.
Restrictive, undersized filter selection generally ranks high on the list causing underperforming HVAC systems. There have been effective electronic air cleaners around for many years, but for our conversation within this article, we will focus on media or fabric material filtering.
ICE agents have arrested an average of over 4,000 illegal immigrants per month compared to the slightly more than 1,700 per month during the Obama administration. The practice of conducting workplace raids, largely unused during the last administration, has returned with vigor as seen in the Southern Provision case and several others.
As the main campus for UBER’s autonomous vehicle research and development labs, the building presented a unique design challenge. Vehicle testing garages sit side-by-side with state-of-the-art conference rooms and office space. This drove the need for zone control and specialized ventilation.
Bob and Tim are on a service call with an aggravated customer. The customer explained to them three different service companies had been out to her house this summer and all of them told her that she had a leak they could not find.

Two other factors in regard to this particular piece of equipment are: A single-pole contactor is used in the compressor circuit, and it is equipped with high and low pressure switches that act as protective devices.
The belief that individual units within rooms are harder to maintain over central air conditioning units, is a myth. Using a condensate removal pump that can service multiple rooms at the same time, such as the Hi-Flow MAX from Aspen Pumps that has multiple inlets, removes the need for multiple condensate pumps on individual units — ergo managing costs effectively.
