"We understand the lifecycle of a building. From concept to occupancy, we keep our customers' facilities operating as intended without issue, along with improving operational efficiency."

Sean Fogli

Executive Vice President

Alliant Systems

Problems and breakdowns are part of life. With our help, HVAC and plumbing issues can be quickly resolved and often prevented.

Many of our clients have long-term preventive maintenance contracts with us. We’ve built great relationships with them and have kept their systems running well, resulting in cost savings and reduced risk, year after year. Our 24/7 service staff includes technicians and field personnel who have handled every crisis under the sun (and rain). Plumbing leaks, cooling system repairs in the peak of summer, heating breakdowns in the dead of winter – we’re there in a flash.

We troubleshoot and repair all types of mechanical and plumbing systems – from built-up systems to VRF/VRV and everything in between. We offer site-specific service contracts that range from basic filter changes to complete building maintenance. Our trained and certified technicians provide commercial clients with troubleshooting, diagnostics, maintenance, repair or replacement of HVAC equipment, components and systems.



The HVAC systems of today have many moving parts that work together. When a part fails and a system crashes, the results can be disastrous. To minimize the risk, many of our clients contract with us for ongoing maintenance service.

Our HVAC maintenance focuses mainly on heating and cooling for large commercial and industrial facilities. Our clients rely on us to monitor their systems’ performance on a regular basis. We keep everything working well to prevent breakdowns and minimize energy use.



Even a small plumbing leak can turn into a huge problem. Our in-house plumbers are fully licensed and bonded for all maintenance repair services. We’re here for you, 24/7 all year long.

More than just plumbing repairs and maintenance, this group also provides backflow device testing. By keeping you up to date on this code-required procedure, we help keep your water safe and the City Inspectors happy.

Last but not least, with annual inspections we help you conserve water, limit waste and minimize sewer and water bills. Even lowering usage a few drops per minute can mean significant savings over time. Every drop counts.



Energy costs are the single largest controllable expense in most commercial and industrial buildings. As a trade ally of Energy Trust of Oregon, we help clients reduce their operating costs and carbon footprint by devising wise, creative strategies for optimal energy consumption.

We crunch numbers and use energy index data to help clients achieve maximum efficiency. We also utilize the latest technology and tools to monitor lighting, CO2, and energy use.

Federal and state incentive programs can be extremely worthwhile. We keep clients apprised of available incentives and help evaluate and implement them. It energizes us.





"Alliant's customer service is top notch. They have great communication from dispatch to the technicians onsite."

-Todd Hepp, EW Corp
