Commercial HVAC Preventative Maintenance in Chatham-Kent
Commercial HVAC Preventative Maintenance Agreements
Most commercial equipment failures are scheduling problems, not equipment problems. A preventative maintenance agreement turns unpredictable repair spending into a budgeted annual line item, extends the service life of equipment you have already paid for, and puts your buildings at the front of the queue when something does go wrong.
Postma maintains 300+ commercial sites under agreement across Chatham-Kent, Sarnia-Lambton and Windsor-Essex — from single-building operations to multi-property portfolios running on one contract and one renewal date.
What We Do on a Maintenance Visit
Select a system to see the actual task list. Every visit includes a detailed report about the work done on each unit and any areas of concern identified (even if not immediate, it is helpful to know whether certain parts are showing signs of wear-and-tear and may require future repairs).

How Preventative Maintenance Saves Money
Maintenance does not save money in the abstract. It saves money through six specific mechanisms, and the two largest are not the ones most people think of.
| Where The Money Comes From | The Mechanism |
|---|---|
| Deferred capital replacement | The largest number by a wide margin, and the one most owners never attribute to maintenance. A rooftop unit is a five-figure capital item. Getting eighteen years out of it instead of twelve is not a repair saving — it is six years of deferred capital on every unit on the roof. With an average rooftop unit, including installation, costing $30,000+ that is instant savings by extending the lifespan of the building’s equipment, and reduces overall annualized capital requirements. |
| Small repair instead of large | Failures are almost always progressive. A worn belt costs very little; the bearing it destroys costs more; the motor after that costs more again. A low refrigerant charge is a leak repair if caught early – if the compressor runs long enough with low refrigerant than it becomes a compressor replacement, which is normally 5-10x the cost of a leak repair. Routine inspections catch these at the cheap end of the sequence, leading to lower overall repair costs over the life of the equipment. |
| Planned rates, not emergency rates | The same repair costs materially more at 9pm on a Saturday during a heat wave than at 10am on a Tuesday when a planned maintenance is done. Customers with regular maintenance avoid these emergency / after-hours calls through proactive management of equipment before it breaks. Our commercial maintenance customers also receive reduced after-hours / emergency call rates. |
| Energy consumption | A dirty condenser coil raises head pressure, and the compressor draws more power for the same cooling. Low charge, restricted airflow and failed economizer dampers all do the same thing. None of it triggers a service call — the unit keeps running and simply costs more to run, every hour, until someone cleans it. Ongoing maintenance helps ensure your equipment is running at 100% efficiency, helping keep the building at optimal temperatures / comfort levels and also reduce your energy bill. |
| Keeping the warranty valid | Manufacturers generally require documented ongoing maintenance for equipment warranty coverage to remain in force. A warranty claim denied because there is no service record turns a covered failure into a full-price repair with no coverage. |
| Downtime you never had | While never seen on your actual expense line, downtime is the silent killer that can impact businesses and employee satisfaction. A restaurant that closes, a manufacturing plant that stops, an office that has to send its employees home for the day, are all issues that can occur when there is unexpected downtime due to system failures and the costs of this can be significant. |
The honest takeaway: maintenance does NOT eliminate repair spending, and any contractor who tells you it does is selling something that isn’t true. What preventative maintenance does is move spending from unplanned to planned, catch failures at the cheap end, and buy you years of additional life on capital equipment you have already paid for, all of which can help reduce overall spend over the life of the equipment while also reducing unexpected downtime.
Capital Replacement Forecasting
The part of a maintenance agreement most owners underuse is the planning, not the servicing.
Because every unit under agreement is tagged with an age, a condition rating and a repair history, we can tell you which assets are likely to need replacing in the next one, three and five years — and roughly what each will cost. That turns a capital plan from a guess into a schedule, and it means a rooftop unit gets replaced in September on a planned basis rather than in January on an emergency basis at a premium.
How Agreements Are Priced
| Factor | Why It Moves the Price |
|---|---|
| Equipment count and type | The base driver. Ten rooftop units take longer than two, and a boiler will typically take longer than a rooftop unit. |
| Visit frequency | Twice a year is the minimum for most buildings. High run-time equipment, or equipment that is mission-critical and downtime is very expensive, such as refrigeration, kitchen make-up air and process cooling is usually quarterly. |
| Access and site conditions | Roof access, lift or ladder requirements and confined mechanical rooms all affect time on site. |
| Consumables included | Filters and belts can be included in the agreement or billed as used. Including them makes the annual number more predictable. |
| Number of sites | We offer preferred rates to customers with large portfolio’s as it helps us reduce travel time and makes the scheduling of technicians more efficient |
We scope every agreement to the building rather than selling a fixed tier. Send us an equipment list, or we will walk the site and build one tailored to your needs.
Preventative Maintenance FAQ
How often should commercial HVAC equipment be serviced?
Twice a year minimum — once before heating season and once before cooling season. High run-time equipment such as refrigeration, kitchen make-up air and process cooling typically needs quarterly service.
Do you service equipment installed by another contractor?
Yes, and many of our maintenance customers came to us that way. We inspect and document what is already on the building, tag the assets, note existing deficiencies, and build the service history from there.
Are repairs included in the agreement?
The agreement covers scheduled inspection and maintenance. Repairs found during a visit are quoted separately so you approve the work and the cost, but agreement customers receive priority dispatch and no overtime premium on after-hours calls.
What does a customer actually receive after each maintenance visit?
An electronic report per unit covering what was inspected, readings taken, work performed, and any deficiency found with a recommendation attached. Assets are tagged so the history follows the equipment. Our technicians review previous reports to see if readings on specific equipment has worsened, indicating a potential issue, and our technicians also take detailed photos to ensure you have a full understanding of the report / diagnostic readings.
Can one agreement cover several buildings?
Yes. We currently maintain 300+ commercial sites under different agreements, including multi-building portfolios consolidated into one contract and one renewal date, with per-site reporting retained so costs can be allocated back to each property.
Does maintenance actually extend equipment life?
It is the largest single factor after installation quality. Dirty condenser coils raise head pressure, low refrigerant charge leads to compressors running “hot”, and slipping belts wear bearings — none of which triggers a service call until something fails. Maintained units much more reliably reach the top of its expected service range; neglected units often fail well short of its expected range.
Can you cover plumbing and electrical on the same agreement?
Yes. Backflow preventer testing, commercial water heating, electrical safety inspections and generator service can sit on the same agreement as HVAC, on one schedule and one renewal date. See our commercial plumbing and commercial electrical services.
How do we get started?
Give us an email (contact@postma.ca) or a call (519-354-9491) and our team will take it from there. We will walk the site, take inventory of the equipment, and come back with a scoped proposal and an annual price. If there are only a few pieces of equipment, and the equipment is fairly standard, then we can likely give you an estimate based on a phone conversation where we discuss what equipment is on-site and what equipment you’d like maintained as well as the visit frequency.
