If it fails: the first hour
What the site contact should do before the technician arrives.
- If a seasonal task was clearly missed and a failure has occurred, treat it as the relevant emergency type, such as a water leak or HVAC failure
- Document what was missed to correct the schedule for the following year
- Contact the appropriate specialist contractor for the failure that resulted
What fails
Exterior water lines and irrigation not winterized in timeAn unexpected early freeze bursts irrigation lines or exterior spigots that were not blown out or shut off in time, causing water damage that costs far more than the winterization task itself.
HVAC systems started cold without a pre-season checkHeating systems switched on for the first time in fall without inspection run into failures during the first genuinely cold week, when demand for repair technicians is highest and response times are slowest.
Gutters and drains clogged before the wet seasonLeaves and debris that accumulate through fall block gutters and roof drains right when rainfall or snowmelt increases, leading to overflow and water intrusion at the roofline.
Snow removal contracts signed too lateWaiting until after the first snowfall to secure a snow removal contract often means paying premium rates or getting placed lower in a contractor's route priority for the rest of the season.
Landscape and irrigation not prepared for summer heatIrrigation systems not checked and adjusted before summer heat arrives lead to either water waste from leaks or dead landscaping from insufficient coverage.
Exterior lighting timers not adjusted for daylight changesPhotocells and timers left on a fixed schedule from the prior season leave a lot dark during early winter evenings or wastefully lit during long summer days.
Pavement and sealcoating work missed in its narrow weather windowSealcoating and asphalt repair require a specific temperature range to cure properly, and missing the spring or fall application window pushes the work into a season where it cannot be done correctly.
What a service call includes
- Winterizing exterior water lines, irrigation systems, and any equipment vulnerable to freezing
- Performing pre-season HVAC service on both heating and cooling systems before peak demand
- Cleaning gutters, roof drains, and site drainage before the wettest part of the year
- Confirming snow removal or landscape contracts are signed and scheduled before the season's first event
- Adjusting exterior lighting timers and photocells for the season's daylight hours
- Inspecting weatherstripping, door seals, and window caulk before temperature extremes arrive
- Scheduling pavement sealcoating or crack repair within the material's required temperature window
Preventive checklist
The items a maintenance program should carry for this system. Build a combined checklist across systems with the checklist builder.
Spring
- Service cooling systems and change filters before warm weather increases demand
- Inspect and activate irrigation systems, checking for winter freeze damage
- Clean gutters and drains after winter debris and check for winter damage to roofing and flashing
- Schedule sealcoating and pavement repair within the season's application window
Fall
- Winterize exterior water lines, irrigation, and any freeze-vulnerable equipment
- Service heating systems before the first cold snap
- Clean gutters and drains before leaf drop increases debris load
- Finalize and sign snow removal contracts before the first forecasted snowfall
- Adjust exterior lighting timers for shorter daylight hours
Quarterly
- Walk the site for any seasonal task that was missed or deferred
Annual
- Review which seasonal tasks were completed on time and which slipped, to improve next year's timing
What it costs
| item | typical range | what moves it |
|---|---|---|
| Irrigation winterization, small commercial site | $150 to $500 | Cost depends on the number of zones and whether compressed air blowout is needed. |
| Pre-season HVAC tune-up, per unit | $150 to $400 | Rooftop units cost more to service than smaller split systems due to access. |
| Gutter and roof drain cleaning | $200 to $800 | Cost scales with roof size, number of drains, and accessibility. |
| Full seasonal readiness service bundle | $500 to $3,000 | Bundling HVAC, drainage, irrigation, and exterior checks in one visit typically costs less than scheduling each separately. |
National ranges. Local labor, access, after-hours timing and materials move them. Multi-site programs usually price below one-off calls.
How to choose a provider
- Ask whether the provider tracks seasonal deadlines proactively or waits for the facility to call
- Confirm they can bundle multiple seasonal tasks into a single visit to reduce disruption and cost
- Ask how far in advance they recommend scheduling snow removal or HVAC contracts relative to the season's start
- Request a sample seasonal checklist to see how specific and site-built their approach is
- Confirm they flag issues found during a seasonal visit that need repair beyond the routine task list
Questions
When should a commercial building be winterized?
Exterior water lines and irrigation systems should generally be winterized in early to mid fall, well before the first hard freeze is expected in the region.
What is included in a fall building maintenance checklist?
Winterizing water lines and irrigation, servicing heating systems, cleaning gutters and drains, finalizing snow removal contracts, and adjusting exterior lighting timers for shorter days.
Why does HVAC need pre-season service instead of just running it when needed?
A pre-season check catches worn components, refrigerant issues, or ignition problems before the system is under full load, avoiding a failure during the first week of extreme temperatures when repair demand and wait times are highest.
What is the best time of year for sealcoating or asphalt repair?
Most sealcoating products require air and pavement temperatures within a specific range, generally above 50 degrees Fahrenheit, which typically limits the work to late spring through early fall depending on the climate.
