The air around us is filled with particles like dust, dander, pollen, smoke, odors and even pathogens including mold, viruses and bacteria. Pro has found a solution to clean the air by partnering with Global Plasma Solutions (GPS). GPS’ patented needlepoint bipolar ionization (NPBI®) technology cleans the air by introducing ions into the space via the airflow in your ventilation system. This technology delivers indoor air that is free of ozone and other harmful by-products. Through NPBI, GPS products improve the air by reducing airborne particulates, odors and pathogens.

By keeping indoor air cleaner, NPBI reduces the amount of air required from outside to keep things fresh—saving you initial ventilation equipment costs and up to 30% on energy consumption.

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.

The Washington State Energy Code effective date is February 1, 2021. Building permits submitted on or after February 1, 2021 must meet requirements of the 2018 Edition of the Washington State Energy Code-Residential (2018 WSEC-R) or the 2018 Edition of the Washington State Energy Code-Commercial (2018 WSEC-C). The Washington Department of Commerce released its 2021 State Energy Strategy in January 2021. The Energy Strategy recommends many policy initiatives in multiple sectors.

Electricity: The Clean Energy Transformation Act (CETA), adopted by the Washington legislature in 2019, requires the transition to 100% non-emitting electricity by 2045. The Strategy recommends increased investment in efficiency measures, renewable generation and transmission infrastructure, energy market reforms, and the development a smart and flexible electric grid that includes distributed energy resources, demand response programs, microgrids and storage.

Buildings: The Strategy emphasizes increased efficiency and the transition from fossil fuels to electricity for water and space heating in both residential and commercial buildings. It recommends revisions to the state energy code to adopt zero-carbon and all-electric construction and efficiency requirements.

The Foundation for Greater Comfort and Efficiency

Challenges like space utilization, energy cost and physical space can take up precious time and resources. Pro found a solution to this problem. We have partnered with Honeywell Building Automation to offer a wide array of products and solutions. Honeywell specializes in building solutions that are easier to manage and provide efficient climate controls and provide better data to assist in decision making. Honeywell’s building management systems help to enable smarter buildings, simplify your facility operations, increase occupant comfort and maintain operational and energy efficiency as your business grows.

Building Information Modeling (BIM) is an invaluable tool for the construction industry. During the design phase, BIM can quickly iterate on design elements, including building form, sustainability, client requests, municipal regulations, budget and more.

What our Customers are Saying

“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.”

“Pro Mechanical Services has been an outstanding partner for integrating our critical facility solutions. As with every museum, the MAC requires precise, high-performing climate control to preserve its treasures. But we also had a goal to reduce energy. With Pro’s full scope of capabilities, they developed solutions to meet our goals of managing climate control on a per-room basis, optimize energy savings, improve our security system and increase efficiency with an integrated solution. Pro now manages 90 percent of our service and maintenance remotely, providing the MAC continued cost savings.”

“I wanted to thank you for fixing our home in a fast, timely manner. My son was three days out of surgery and needed electricity for his medical devices. The electricians from Pro were fast and worked hard to reconnect our power. We learned from talking with them that they had been up all night on a previous job, and after completing the work at our house, they were off to another project. These men were polite and hard workers. I will definitely recommend your company in the future.”
