Programs cover rooftop units, split systems, VRF, boilers, unit heaters, make-up air, chillers, cooling towers and controls. We currently have 1,400+ RTUs under contract and 85+ chiller plants on PM. Most HVAC failures announce themselves weeks before they happen. A contactor starts to pit. A belt glazes and slips. A condenser coil loads up with cottonwood and the compressor runs hot. A heat exchanger develops a hairline crack. Without scheduled visits, those signs get missed until a unit fails on the hottest or coldest day of the year, when parts and technicians are hardest to get. Single-site visits cost $185. Quarterly programs for smaller buildings usually run $4,800 to $18,000 a year, and building-wide programs run $18,000 to $85,000 a year. Reactive HVAC spend averages 40% more than planned PM. ## What Does a Commercial HVAC Maintenance Program Cover? ### Rooftop units and split systems Filters, belts, bearings, coils, condensate drains and pans, electrical connections, contactors and capacitors, refrigerant pressures, economizer operation and thermostat calibration. Heating season adds combustion analysis and heat exchanger inspection. ### Boilers and heating equipment Burner and flame safeguard checks, low-water cutoff testing, combustion tuning, venting inspection and pump and valve checks. Gas work follows CSA B149.1. ### Chillers and cooling towers Refrigerant and oil logs, approach temperatures, tube condition, water treatment, basin and fill condition and legionella sampling. See commercial chiller service [/commercial-chiller-service/ →](/commercial-chiller-service/) and cooling tower service [/cooling-tower-service/ →](/cooling-tower-service/) for plant-specific programs. ### Controls BAS alarms, setpoints, schedules and sensor calibration. A wrong schedule can run a whole floor of equipment all weekend. ## Monthly vs Quarterly vs Semi-Annual: Which Fits Your Building? | Frequency | Best fit | Why | | --- | --- | --- | | Semi-annual | Small offices, light industrial, low run hours | Spring cooling and fall heating start-ups cover the basics | | Quarterly | Restaurants, retail, busy offices | Filters and coils foul faster with high run hours | | Monthly | Towers, hospitals, chiller plants, server rooms | Critical loads and plant logs need close tracking | ## When Do You Need a Maintenance Contract? - Your building has more than a handful of rooftop units and no record of their age or condition. - Emergency calls are eating the repair budget every July and January. - Your board, landlord or insurer is asking for written maintenance records. - You are planning capital replacement and need data on which units to replace first. - You operate multiple sites and want one contractor and one report format. Our property manager programs [/commercial-hvac-for-property-managers/ →](/commercial-hvac-for-property-managers/) cover 3-50+ sites. ## Planned Maintenance vs Reactive Repair Reactive repair looks cheaper until you add up overtime rates, emergency parts, tenant complaints and the shorter life of equipment that runs dirty. A planned program spreads cost evenly, catches small faults while they are cheap and gives you the condition data to plan commercial HVAC replacement [/commercial-hvac-replacement/ →](/commercial-hvac-replacement/) on your schedule instead of the equipment’s. For restaurants and grocery, pair HVAC PM with commercial refrigeration maintenance [/commercial-refrigeration-maintenance/ →](/commercial-refrigeration-maintenance/) on one contract. ## Maintenance Across Toronto and the GTA Our PM routes run through Bay Street and King West towers, Yonge-Sheppard and Yonge-Eglinton offices, Square One and Airport Corporate Centre office parks, Dixie-Mavis and Hwy 410 industrial and retail plazas from Streetsville to Agincourt.

Quarterly programs for plazas, restaurants and low-rise offices usually run $4,800 to $18,000 a year, and building-wide programs for towers and campuses run $18,000 to $85,000 a year. The price depends on how many units you have, their tonnage, visit frequency, and whether chillers, cooling towers and building controls are included. Reactive HVAC spend averages 40% more than planned PM, so most buildings recover the program cost through fewer emergency calls, longer equipment life and lower energy use. We price programs from an equipment inventory, so the contract matches what is actually on your roof and in your mechanical room. ### How often should commercial HVAC equipment be serviced? + Most rooftop units and split systems need at least two visits a year: a spring cooling start-up and a fall heating start-up. Quarterly visits are the norm for restaurants, retail and offices with high run hours because filters load faster and coils foul sooner. Chillers, cooling towers and critical environments such as server rooms and healthcare usually move to monthly visits. Kitchens with heavy grease loads and buildings near highways or cottonwood trees often need extra coil cleaning in early summer. ### What is included in a maintenance visit? + A typical visit covers filters, belts and bearings, condenser and evaporator coil inspection and cleaning, condensate drains, electrical connections, contactors and capacitors, refrigerant pressures, economizer operation, safety controls and thermostats. In heating season we add combustion analysis, heat exchanger inspection, flame safeguard and venting checks. Every visit ends with a written condition report. ### Do maintenance customers get faster emergency service? + Yes. Contract sites get priority routing on the 24-hour line and a 2-4 hour emergency response. ### Can you take over from our current contractor mid-year? + Yes. We start with an equipment inventory and baseline inspection, which often finds deferred work the previous contractor missed. The program starts from accurate data. ### Do you follow ASHRAE Standard 180? + Our checklists follow ASHRAE Standard 180 practice for commercial HVAC inspection and maintenance, adjusted to manufacturer schedules and the equipment on site. ### Will the reports help with our reserve fund study? + Yes. Reports include age, condition and expected remaining life per unit, which reserve fund consultants and asset managers use for capital planning. ### Are repairs included in the contract? + Minor items like filters, belts and coil cleaning are included. Repairs found during a visit are quoted separately at contract rates, and nothing is done without your approval. ### Do you maintain refrigeration equipment too? + Yes. Walk-ins, reach-ins and condensing units are covered under our commercial refrigeration maintenance programs, which can be combined with HVAC PM on one contract. ### Is there a minimum contract length? + Single-site visits can be booked one at a time. Program pricing is based on a one or three-year agreement, with a 30-day exit clause.
