“We worked with Pro Mechanical Services to provide service on our walk-in coolers/freezers and roof top units at our stores. They also provided us with a security package complete with cameras. As we expand our business, we look forward to again partnering with Pro to provide HVAC upgrades at our new site. Pro has consistently provided quality workmanship and a comprehensive preventative maintenance plan tailored to our business.”

Delivering Clean Air in a Pandemic

As a society, we spend 90% of our time indoors. Poor air filtration and poor air purification in buildings may be harmful to occupant’s health. In fact, according to the EPA, indoor air quality is often two to five times more polluted than outdoor air.

Pro partnered with Global Plasma Solutions to offer needlepoint bipolar ionization technology to deliver clean indoor air in commercial, industrial and residential buildings.

These products improve the air by reducing airborne particulates, odors and pathogens. It also lowers energy costs by up to 30% by reducing the need for outdoor air intake.
