When it began “raining” inside the Towson Court House, a leaky roof was assumed to be the culprit. But for the Maryland Department of General Services, the truth turned out to be much stranger.

As one of the larger contributors to a facility’s expenses, it is critical to incorporate preventative measures into regular maintenance and cleaning plans for boilers.

O’Rourke will continue to service accounts throughout North America, working in cooperation with Mestek’s network of sales representatives, wholesale distributor partners, and contractors.

Propane use at Ruby’s Inn has helped eliminate 5,200 metric tons of CO² equivalent. This is equal to the greenhouse gas emissions from 1,410 gasoline-powered passenger vehicles driven for one year.

The home now has a 3.9 kW solar array that offsets nearly 100% of the System M and grid power supplied from the clean-sourced ConEd program — meaning that the house has zero emission heating, cooling, and hot water.

Canneberges Bécancour, one of the most productive cranberry farms in North America, wanted to develop a freezing facility to support a original 17,000-square-foot processing plant.

Refrigerated Solutions Group and Budderfly announced the results of energy efficiency pilot projects across two Subway restaurant locations using RSG’s Capsule Pak ECO™.

The EERS required Indiana’s electric utilities to cut energy delivery by an average of 2 percent annually, as well as providing home energy assessments, low-income weatherization, and efficiency rebates for businesses, homeowners, and schools. In 2014, Indiana legislature passed SEA 340 to cancel the EERS. Then Gov. Mike Pence did not veto or sign the bill, so it became law, and Indiana became the first state to repeal its energy efficiency standard.

Seven of the new full-time employees hired to start up operations previously worked at the VISE-GRIP factory. Malco plans to add jobs as production increases.

A compressor design proposes a new drive mechanism for compressors used for cooling in homes, buildings, airplanes, and cars.

Performing a more detailed inspection of a compressor might reveal a system issue that could lead to a failed compressor.

Little by little, a compressor’s lubricating oil will eventually escape the compressor’s crankcase and enter the system’s tubing.

Compressor manufacturers have been improving the products on multiple fronts in recent months.

When electrically inspecting or troubleshooting a compressor, you should always protect yourself against the possibility of terminal venting.

Any compressor that gets too hot or is overheated is subject to premature wear between its internal moving parts.

Any compressor that gets too hot or is overheated is subject to premature wear between its internal moving parts.

The first step consists of determining the compressor’s mode of failure. Was it electrical or mechanical?

Have 166 years of small improvements and occasional leaps in chemistry taken us to the limit of what compressors can do?

Airflow is one of the leading causes of failure for compressors.

Even though the circulated refrigerant is the working fluid required for cooling, lubricant or oil is needed for lubrication of the compressor’s moving mechanical parts.

Comprehensive troubleshooting can help technicians determine whether the compressor is working properly.
