Zero Upfront Cost. Maximum Performance. Guaranteed.

You need to upgrade, but the funds aren’t there. Navigating the complexities of aging infrastructure and tight capital budgets can be a major hurdle for public entities and building owners.

Performance contracting is a proven, budget-neutral solution that transforms guaranteed energy and operational savings into a dedicated funding source for your projects. As one of the few certified Energy Services Companies (ESCOs) in Washington and Oregon, MacDonald-Miller helps you enhance building performance, extend the life of your critical systems, and achieve your goals with zero financial risk.

We’re not just a contractor; we are your strategic partner, committed to your long-term success.

A Unified Partner

Unlike competitors who rely on multiple subcontractors, we are a full-service, turnkey mechanical contractor with integrated expertise in-house. Our “umbrella” team of engineers, technicians, and project managers work under one roof, providing a single point of accountability. This streamlined approach ensures a cohesive, high-quality project from start to finish, delivering smarter designs and fewer surprises.

Triple-Guaranteed Outcomes

We eliminate your financial risk with our three powerful guarantees. We guarantee a maximum project cost, so if we go over budget, we cover the difference. We guarantee your energy savings, and if the promised savings aren’t met, we write you a check for the difference. And we guarantee the performance of the systems we install, ensuring they work as intended.

Strategic Funding & Proactive Planning

Our team actively identifies and secures all available funding sources, including utility rebates, state and federal grants, and other incentives, often covering a significant portion of project costs. We go beyond execution, providing long-term capital planning, facility assessments, and decarbonization studies to ensure your project delivers lasting value and positions your facility for future success.

Preliminary and Investment-Grade Audits

We conduct thorough assessments to identify opportunities for energy savings and facility improvements.

Long-Term Measurement and Verification (M&V)

We provide ongoing monitoring to confirm that guaranteed energy and cost savings are achieved over time.

Energy Service Proposals

Our team develops detailed proposals with calculated emissions reductions, guaranteed maximum costs, verified savings projections.

Self-Performing 70% of the Work

In support of the core guarantees of our contracting, we ensure efficiency, quality, and accountability by handling the majority of the project execution in-house.
