The Houston commercial building maintenance calendar
A seasonal maintenance calendar built for the Gulf Coast, where the cooling season runs nine months, the growing season never really stops, and hurricane season is a scheduled event.
Written for facilities directors and property managers on the Texas Gulf Coast.
Why does a Houston maintenance calendar differ from a national one?
Gulf Coast buildings run a cooling load close to nine months a year, grow landscape almost year round, and sit inside a hurricane season with a fixed start date, so national maintenance intervals under-serve all three.
A national HVAC interval assumes a shoulder season this region does not really get. A national landscape schedule assumes dormancy. And no national calendar has a June 1 line item for storm readiness.
The practical effect is that equipment here accumulates run hours faster, exterior surfaces degrade faster in the humidity, and there is a hard deadline every year that most buildings treat as a surprise.
What should be done before cooling season?
Complete full HVAC preventive service in February and March, before the first sustained heat rather than during it.
- Full HVAC PM
Coil cleaning, belts, bearings, charge verification, condensate lines cleared and treated. Booked in February, not May.
- Condensate management
The most common avoidable cooling-season failure in this climate, and it floods ceilings when it goes.
- Filter program reset
Interval confirmed for the season's load.
- Thermostat and control check
Programming verified against actual occupancy rather than last year's.
- Roof inspection
Before the storm season, while a repair is still a repair.
What has to be done before hurricane season?
Storm preparation has a fixed deadline of June 1, and the work that matters is drainage, roof condition, exterior securing and having the vendor list assembled before anyone needs it.
- Roof and flashing
Inspected and repaired. The damage a storm does is usually to something already compromised.
- Drainage and roof drains
Cleared. Ponding is what turns rain into an interior loss.
- Site drainage
Storm inlets, swales and detention clear of debris.
- Tree work
Structural pruning and removal of limbs over parking, walkways and the building. Do it in spring.
- Exterior securing plan
What gets brought in or tied down, decided and written before a watch is issued.
- Generator and life safety
Tested under load, not just started.
- Vendor contact list
Assembled and current. After a storm every contractor in the region is booked within hours.
What runs on a continuous cycle here?
Landscape, exterior cleaning and pavement maintenance run year round on the Gulf Coast because the climate never fully pauses any of them.
| Item | Cycle | Note |
|---|---|---|
| Landscape service | Weekly Mar-Oct, biweekly Nov-Feb | St. Augustine turf often stays weekly year round |
| Irrigation audit | Twice yearly | Catches the leaks that show on the bill before the turf |
| Entry and walkway washing | Quarterly | Humidity and traffic; entries darken fast |
| Building exterior washing | Annual to semi-annual | Shaded elevations grow algae and need it sooner |
| Parking lot sweeping | Monthly | More often for retail and food tenants |
| Parking lot restriping | Every 18-36 months | Fire lanes and accessible marking usually sooner |
| Window cleaning | 2-4 times yearly exterior | Storefront and entry glass monthly to quarterly |
| Periodic floor care | Quarterly to annual | By surface type and traffic |
What gets missed most often?
The four items most often missing from a Houston building's maintenance program are roof drains, irrigation audits, emergency lighting testing and parking lot striping.
All four share a profile: cheap to maintain, invisible while working, and expensive or citable when they fail. Nobody notices a clear roof drain, and everybody notices the ceiling it took out.
Emergency and exit lighting testing deserves particular mention because it is a documented requirement and one of the first things an inspector asks to see records for.
Questions we actually get asked
When should HVAC preventive maintenance be scheduled in Houston?
Book the main preventive visit for February or March, before sustained heat. The second visit falls in the autumn after the cooling season has finished loading the equipment.
How often should roof drains be cleared on the Gulf Coast?
At least twice a year, plus before hurricane season and after any significant storm. Buildings with tree cover need it more often, because the failure mode is ponding and ponding becomes an interior loss.
When should hurricane preparation start?
The physical work — roof, drainage, tree pruning — belongs in spring, finished before June 1. Preparing after a storm is named is preparing too late, because every contractor in the region is already committed.
