Keeping your facility comfortable can be a challenge, particularly as seasons change. Having a partner who can design, recommend, install, and maintain your heating and cooling systems can make all the difference.

At Marsden, we focus our efforts on outcomes that limit complaints, lower your total cost of operation, and improve efficiency.

The single biggest complaint made to respondents of the Building Operating Management survey was temperature, with 68 percent of respondents saying this was their number one issue. Temperature is also the largest daily source of complaints — 16% of respondents say they field a hot/cold call every day.

How do we innovate? By using predictive analysis to identify measures that result in dramatic cost savings over traditional mechanical approaches. To learn more about our complete line of office services click here.

Special Report

Guy MingoThe Case for Vendor Consolidation, by Guy Mingo, CEO

“With Marsden Holding, customers get a national presence with local dedication,” says Guy Mingo, CEO of the St. Paul-based commercial cleaning powerhouse. That statement seems to be the unofficial motto of the company as the phrase is reiterated by not only Mingo, but several of the presidents of the companies Marsden Holding has acquired.

Comprised of 23 companies operating in 46 states, it’s easy to see what Mingo means about national strength. However, to understand the other part — being a local player — one simply has to look at a few of Marsden Holding’s larger acquisitions: SCIOTO Services of Columbus, OH; Aztec Facility Services of Houston, TX; or CleanPower of Milwaukee, WI. None are known as Marsden Holding, but rather they maintain their vitally important regional identity. Complete story here.
