Maintenance Plans in Tustin, CA
A Tustin plan has to serve both halves of the city. For newer buildings, our scope leans toward controls verification, economizer function tests, and sensor calibration, since early-life problems tend to live in configuration. For older strip centers and medical offices, the scope emphasizes coil and drain condition, electrical connections, refrigerant circuit health, and a candid look at remaining service life. Either way, each rooftop unit receives an asset tag, readings are stored in the DaVinci Portal, and owners receive a short forecast of probable replacements, which helps align capital spending with the lease and refinancing calendar.

How maintenance plans work plays out in Tustin
Maintenance in Tustin works best when the program is matched to the building's generation. The Legacy and Village campus buildings carry newer rooftop units with factory controls, and the value of a visit there is verification: economizers actually modulating, sensors reading true, filters sized correctly, condensate lines clear before the first humid week. The older Red Hill, Edinger and Newport Avenue buildings carry a different need. There, the visit is condition assessment, and the most useful output is an honest ranking of which units will make it through another summer and which should be on the replacement schedule.
Seasonal timing is driven by the inland heat. Spring visits in April and May get coils cleaned and refrigerant charge verified before the first run of 95-degree days; fall visits in October catch heat exchangers and gas trains before the handful of cold mornings Tustin actually gets. Restaurants at The Market Place and The District run quarterly because refrigeration, ice and kitchen exhaust do not tolerate a six-month gap. Medical office along Red Hill usually settles into bi-annual with a priority response clause, and the light-industrial and professional office buildings in Old Town often fit an annual visit with filter changes in between.
Every visit is recorded per asset in the DaVinci Portal, which is what makes a program useful to a property manager who oversees several buildings and to a landlord who needs to show a prospective tenant the condition of the equipment they are inheriting. Details on tiers and what each includes are on the Tustin plans page and the preventive maintenance guide.

- Flag anything trending toward failure before it becomes a breakdown
- Deliver a photo-logged report after every visit
- Free diagnostic on any repair that comes out of the visit
- Equipment that 'seemed fine' failing without any maintenance history to catch the trend
- Multiple pieces of equipment aging out around the same time with no replacement plan
- Surprise repair costs that a documented PM history would have flagged months earlier
- Multi-location accounts with no consistent record across sites
