An Authorized Reliable Controls Dealer
As an authorized Reliable Controls dealer, we provide building automation solutions designed for long-term performance, flexibility, and ease of use. Our team supports facilities through system design, installation, programming, troubleshooting, documentation, and ongoing service, helping owners and facility managers maintain better control over comfort and energy use.
Practical Controls That Deliver Results
We’re built around a simple idea: controls should solve problems, not create them. That means clear system design, clean programming, and a service mindset that doesn’t disappear after install.
Whether you’re upgrading an aging controls system, expanding a campus, or trying to reduce utility spend, Quality Controls Service and Solutions focuses on practical improvements that translate into measurable operational efficiency without sacrificing occupant comfort.
Focused on Education and Mission-Driven Facilities
Quality Controls Service and Solutions works extensively in K-12 schools, churches and private schools, and higher education, where dependable operation and predictable budgets matter.
We understand the day-to-day realities: limited maintenance bandwidth, tight schedules, and the need to keep classrooms, sanctuaries, and common areas comfortable and safe.
Our approach prioritizes stability, ease of use, and long-term support so your team can manage the building with confidence.
Support Beyond Installation
From troubleshooting and optimization to full modernization projects, Quality Controls Service and Solutions is a partner you can rely on for the full lifecycle of your system.
We combine technical expertise with straightforward communication, helping you make informed decisions and maintain performance over time through responsive service, documentation, and ongoing system tuning.
As a building automation company focused on long-term relationships, we stay involved after installation to help facilities maintain performance, improve reliability, and adapt their systems over time.
