Titus VAV Box & Terminal Unit Service in Phoenix, AZ
The box above the ceiling that decides whether the corner office is comfortable. Titus makes a great many of them.
Titus, part of Air Distribution Technologies under Johnson Controls, is among the largest manufacturers of VAV terminals, diffusers and grilles in North America, and its boxes are above the ceilings of Phoenix office buildings, hospitals, schools and government facilities by the thousand. The company also builds fan coils and chilled beams for zone-level conditioning. Bleuwave services Titus terminal equipment as an independent contractor, without dealer affiliation or factory authorization.
A VAV box is a simple sheet-metal assembly — a damper, a flow sensor, sometimes a fan and a reheat coil — governed by a controller that may have come from Titus, from the building automation vendor, or from a pneumatic thermostat installed decades ago. The box lasts; the controls age. Most hot-and-cold complaints in a Phoenix VAV building trace to a box, and most of those to its controls.

Titus Terminal Equipment
Single-duct VAV boxes throttle cold primary air to zone demand; fan-powered boxes (series and parallel) mix plenum air for heating and constant airflow; dual-duct units blend hot and cold decks. Reheat comes from hot-water coils or electric elements. Controllers are factory-mounted from Titus's own line or from building automation platforms — Trane, Johnson Controls, Carrier, Siemens, Distech and others — or field-installed, and older buildings run pneumatic actuators. Titus diffusers and grilles deliver the air; a diffuser that whistles or dumps cold air on a desk is often a box problem upstream.
Service in Phoenix
Ceiling plenums in Phoenix run hot, shortening actuator and controller life and warming the plenum air that fan-powered boxes mix in. Dust drifts flow sensors. Reheat coils that see no hot water for eight months surprise everyone on the first cold morning. Dampers that throttle in a narrow range for six months may not stroke fully when needed. We diagnose at the box — sensor, controller, actuator, damper stroke, measured airflow against design, reheat operation — and work back to the air handler when the boxes are not the problem. Repairs cover actuators, dampers, flow sensors, controllers, reheat valves and coils, and fan-powered box motors; pneumatic-to-DDC conversion and test-and-balance are the systematic remedies, coordinated with the building automation practice.
Straight Answers
Questions About Titus Equipment
One office is always hot. Is it the Titus box?
Almost always — a failed actuator, a stuck damper, a drifted flow sensor or a controller problem. We diagnose at the box, which requires getting into the ceiling and testing it, and the repair is usually modest.
Do you convert pneumatic Titus boxes to DDC?
Yes. New actuators, controllers and sensors on existing boxes, integrated with the building automation system — one of the highest-value controls projects in an older office building.
Is Bleuwave a Titus representative?
No. We service Titus equipment as an independent contractor without dealer affiliation or factory authorization.
