In an effort to reduce the more than 700 deaths that occur due to carbon monoxide (CO) poisoning each year and ensure a safe winter heating season, northern Virginia HVAC contractor Jones-Rogers Inc. emphasizes the importance of an HVAC system check-up to avoid the risk of CO exposure.

Reducing refrigerant in direct expansion (DX) HVAC system designs is a trend both contractors and consulting engineers are using to distance themselves from the competition. While refrigerant reduction has been fairly common in conventional air conditioning, it’s only now emerging in the category of indoor pool (natatorium) dehumidification.

It happens all the time: The hard-working crew at a small business loses customers thanks to the sour grapes of one person. It could be a disgruntled employee, an angry customer, or even a competitor. But as damaging as a bad review can be, positive reviews can be equally constructive.

According to the National Renewable Energy Laboratory (NREL), about three in four residential buildings have physical restrictions to going solar.

Bob and Tim were on their way to a residence outside of town where the homeowners’ complaint was excess humidity in the house.

Disability claims are always challenging for employers, but this is especially the case when pregnant workers suffer complications that leave them unable to perform their normal job duties.

The Monterey County Office of Education (MCOE), along with Chevron Energy Solutions, unveiled a new solar power and energy efficiency project that is expected to reduce MCOE’s overall energy demand by as much as 75 percent while yielding an expected savings of $2.2 million during the first 25 years of the project.

This troubleshooting problem brings you to a three-bedroom, ranch style home on a concrete slab, which, as most typically do in this area of the Southwest, employs a rooftop evaporative cooling system in the summer and an upflow forced-air gas furnace for heating in the winter. The customer says one of the bedrooms “just won’t get comfortable.”

Hospitals use a lot of energy to save lives. To find ways to cut the energy intensity of large hospitals as well as schools and retail buildings by half, DOE’s Commercial Buildings Program and its National Renewable Energy Laboratory (NREL) are working together with ASHRAE and other members of the building industry.
