We work on Johnson Controls Metasys, Siemens Desigo, Honeywell Niagara and Delta Controls, and integrate equipment over BACnet IP, BACnet MSTP and Modbus RTU. Most buildings get far less from their BAS than they paid for. Schedules are overridden and forgotten, so equipment runs all weekend. Alarm lists fill with nuisance alerts until operators stop reading them. Sensors drift and VAV controllers fail, so comfort calls pile up. Constant-speed fans and pumps run flat out whatever the load. Fixing controls is often the cheapest energy and comfort upgrade a building can make. Controls projects typically run $15,000 to $180,000. VFD retrofits typically pay back in 3-5 years. ## What Does BMS and Controls Work Include? ### Controls audit and tune-up Point list review, override clean-up, schedule and setpoint optimization, alarm rationalization, trend set-up and sensor recalibration. ### VFD retrofits Variable frequency drives on supply fans, return fans, cooling tower fans and pumps, with control sequences and BAS points. ### Integration New rooftop units, chillers, boilers, make-up air units and VRF systems tied into the existing BAS over BACnet or Modbus. ### Upgrades and new installs Controller replacement, new front ends, graphics and complete BMS installations for new buildings and major retrofits. ## Controls Projects and Typical Payback | Project | Typical cost | Typical payback | | --- | --- | --- | | Schedule and override clean-up | Part of $15K-$40K tune-up | Often under 1 year | | VFDs on fans and pumps | $20K-$90K | 3-5 years | | Chiller plant sequence optimization | Quoted | 2-4 years | | Full BMS upgrade | $60K-$180K | Varies with scope | ## Signs Your Controls Need Attention - Equipment running nights and weekends with no one in the building. - Hundreds of overrides or alarms nobody acts on. - Chronic hot and cold complaints in the same zones. - New equipment that never got integrated into the BAS. - Energy use climbing with no change in occupancy. ## Controls and the Plant Chiller plant sequences, condenser water reset and cooling tower fan control drive a large share of tower energy. Our controls team works directly with our commercial chiller service [/commercial-chiller-service/ →](/commercial-chiller-service/) and cooling tower service [/cooling-tower-service/ →](/cooling-tower-service/) crews so sequences match the equipment. New installs are integrated through our commercial HVAC installation [/commercial-hvac-installation/ →](/commercial-hvac-installation/) projects. ## BMS and Controls Across Toronto and the GTA We work in Bay Street and Yonge corridor office towers, downtown hospitals and universities, Scarborough and Etobicoke institutions, Hwy 404 tech campuses in Markham and industrial plants in Vaughan and Brampton.

Why Us ## Why Choose Toronto Commercial HVAC for BMS & Controls? ### Mechanical and Controls Together Our controls team works beside our chiller and RTU crews, so sequences match how the equipment really behaves. ### Four Major Platforms Johnson Controls Metasys, Siemens Desigo, Honeywell Niagara and Delta Controls. ### Open Protocols BACnet IP, BACnet MSTP and Modbus RTU integration, so new equipment talks to the existing BAS. ### VFD Payback Variable speed drives on fans and pumps typically pay back in 3-5 years, often faster with incentives. ### Alarms You Can Trust Alarm lists cleaned up so the alarms that matter are not buried under nuisance alerts. ### Trends That Find Problems Trend logs set up to catch failing VAVs, short cycling and plant drift before tenants call. ## Repair or replace? Get the numbers first. A $185 diagnostic gives you written findings per unit, waived when the approved repair is over $750.

A controls tune-up on an existing system, covering schedules, setpoints, overrides, alarms, trends and sensor recalibration, usually costs $15,000 to $40,000. VFD retrofits on supply fans, return fans and pumps typically run $20,000 to $90,000 and often pay back in 3-5 years. Full BMS upgrades or new installs with new controllers, a new front end and integration of rooftop units, plant and VAV run $60,000 to $180,000. The biggest variables are point count, platform, network condition and how much existing hardware can be reused. ### Which BMS platforms do you work on? + Johnson Controls Metasys, Siemens Desigo, Honeywell Niagara and Delta Controls. We integrate other equipment over BACnet and Modbus. ### What is a VFD retrofit and why does it save energy? + A variable frequency drive lets a fan or pump motor run only as fast as the load needs. Because fan and pump power drops sharply with speed, even modest speed reductions save a lot of energy. Retrofits on constant-speed fans and pumps typically pay back in 3-5 years. ### Can you integrate new rooftop units into our existing BAS? + Yes. Most modern RTU controllers support BACnet. We integrate points, alarms and schedules at start-up. ### Our BAS is full of overrides. Can you fix that? + Yes. Overrides, stale schedules and nuisance alarms are the most common problems we find. A tune-up clears them and documents why each remaining override exists. ### Do you offer BAS service contracts? + Yes. Ongoing support for programming changes, alarm response and trend reviews, often bundled with mechanical PM. ### Are there incentives for controls and VFD projects? + Often. Enbridge and IESO programs support controls and VFD measures. We help with pre-approval paperwork. ### Can you take over from our original controls contractor? + In many cases, depending on platform licensing and access. We assess what is needed before committing. ### Do you provide operator training? + Yes. Every project ends with operator training on graphics, alarms, trends and schedules. ### How do controls connect to tenant comfort? + Failed VAV controllers, bad sensors and poor schedules cause most chronic hot and cold calls. Trend data shows the problem zones before tenants do.
