Equipment Expertise
What are HVAC controls?
HVAC controls coordinate heating, cooling and ventilation equipment. They range from local thermostats and sensors to building automation systems that manage schedules, alarms and operating sequences across a property.
Where you’ll find this equipment
- Office and multi-tenant buildings
- Retail and commercial properties
- Buildings with centralized scheduling
- Facilities monitoring multiple mechanical systems
System Operation
How It Works
Sensors report conditions such as temperature and pressure to a controller. The controller compares those readings with setpoints and programmed sequences, then commands fans, valves, dampers and other equipment. A building automation network can share information and provide a common operator interface.
Equipment Overview
Main Components
Sensors and thermostats
Measure conditions and communicate space demand.
Controllers
Apply schedules, setpoints and equipment sequences.
Actuators and relays
Translate control commands into equipment action.
Networks and interfaces
Connect devices and present operating information and alarms.
Common Problems We Find
- Incorrect schedules or setpoints
- Sensor drift or failed sensors
- Stuck actuators and control valves
- Communication or network faults
- Equipment left in manual override
- Conflicting heating and cooling sequences
Why Maintenance Matters
Control checks should confirm both the command and the equipment’s response. Reviewing sensor readings, alarms, schedules and overrides helps identify comfort and energy issues that mechanical repairs alone may miss.
- More consistent building operation
- Earlier identification of wear and deficiencies
- Clearer repair and replacement priorities
The RK Approach
Service that considers the whole building
RK Climate Control supports commercial equipment troubleshooting, preventative maintenance and replacement planning throughout the Lower Mainland. We focus on practical diagnostics, clear documentation and the way each piece of equipment works with the rest of the building.
