Quick answer
Commercial HVAC maintenance puts rooftop units, split systems and make-up air units on a regular schedule, usually quarterly for restaurants and twice a year or quarterly for offices and retail. Each visit covers filters, belts, coils, drains, electrical parts and controls, with written notes per unit. Typical Pasadena pricing runs $147 to $297 per unit per visit. Call (626) 879-0711.
Commercial HVAC Maintenance
What commercial hvac maintenance covers at your home
Commercial equipment runs many more hours than a home system. An office rooftop unit might run 12 hours a day, five or six days a week. A restaurant's units can run from early prep through late cleanup, seven days a week, while the kitchen exhaust pulls grease and heat through the building. Filters load up faster, belts stretch, coils coat over, and drains clog. Skipped maintenance shows up as a breakdown on the hottest day of the year, usually during the busiest hours.
Marco's builds a maintenance schedule around your building and your business. A restaurant may need quarterly visits with monthly filter changes, while an office with clean air and moderate hours may do well with two visits a year plus a filter change between them. Every unit gets its own record, so you and your property manager can see what was done, what is wearing, and what to budget for. Our own technicians do the work, and we call ahead to confirm access.
Warning signs
Signs your building needs a maintenance program
Breakdowns during peak hours
If units fail on busy afternoons or during the lunch rush, the cause is often wear that a scheduled visit would have caught, such as a glazed belt or a weak capacitor.
Filters changed only when clogged
Filters left until they collapse or bypass air let dust and grease coat the indoor coil. Cleaning a coated coil costs much more than a filter program does.
No records for the rooftop units
Many tenants and owners cannot say when the units were last serviced. Without records, budgeting for replacement and handling warranty questions turns into guesswork.
Ceiling tiles keep staining
Repeated water stains under rooftop units point to drain pans and traps that need regular cleaning. A schedule clears them before the overflow reaches ceilings and inventory.
Energy bills climb each summer
Dirty condenser coils, slipping belts and stuck economizers raise energy use on PWP or SCE bills. Regular maintenance keeps units running closer to their rated efficiency.
Lease requires HVAC service
Many commercial leases require tenants to maintain HVAC equipment and keep records. A documented program covers that requirement and avoids disputes at lease end.
Choosing a maintenance schedule
The right schedule depends on run hours, the air the unit breathes and how costly downtime is. Restaurants usually need quarterly visits, because grease-laden air coats filters and coils quickly and make-up air units have their own burners, belts and filters. Medical and dental offices often want quarterly service for air quality and comfort. General offices and retail spaces with moderate hours can often do well with two full visits a year, spring and fall, plus a filter-only visit in between.
We look at the equipment, the building and the business before recommending a schedule, and we adjust it after the first year based on what we see. If filters come out barely dirty, we stretch the interval. If belts and coils are wearing fast, we shorten it.
- Restaurants and food service: quarterly visits with monthly filter changes
- Medical, dental and clinic suites: quarterly visits focused on filtration and drains
- Offices and retail: spring and fall visits plus a filter visit in between
- Churches and venues: visits timed before heavy use seasons and events
What a commercial maintenance visit covers
Each visit follows a checklist for each unit. We replace filters, inspect and adjust or replace belts, check pulley alignment, lubricate bearings where the motor allows, clean or inspect condenser coils, and clean drain pans and traps. On the electrical side, we test capacitors and contactors, tighten connections and check motor amperage. Refrigerant circuits are checked for signs of leaks and proper operation. On gas-fired rooftop units, the heating visit includes burner inspection, ignition, flame sensing, the heat exchanger where it can be seen, and venting.
Economizers get attention on every visit. An economizer uses cool outdoor air instead of the compressor when conditions allow, but its dampers and actuators often stick, either open (bringing in hot air all summer) or closed (wasting free cooling on mild evenings). We check the damper linkage, the actuator and the sensor.
Filter programs and what they protect
A filter program puts filter changes on a calendar, separate from the full maintenance visits when needed. We record each unit's filter size and type, stock them, and change them on schedule. Restaurants may need monthly changes. Offices might need them every two or three months. During wildfire smoke events or after Santa Ana wind days, we can add a change. Clean filters protect the indoor coil, which is far harder and more expensive to clean than a filter is to replace.
Higher efficiency filters catch more fine particles, which matters for clinics and during smoke season, but they also restrict airflow more. Before upgrading filters on a unit, we check that the blower can handle the added resistance, so the upgrade does not freeze the coil or cut airflow to the space.
Step by step
How a scheduled maintenance program runs
- 1
Site survey
We visit the building, record every unit's model, serial, refrigerant, belt size and filter size, and note roof access, ladder location and any equipment showing heavy wear.
- 2
Set the schedule
Based on run hours, business type and equipment condition, we recommend visit frequency and a filter interval, and we price the program per unit per visit.
- 3
Visits confirmed ahead
We call the manager before each visit, confirm access and timing, and schedule shutdowns for slow hours. Most work happens on the roof without disrupting business.
- 4
Unit by unit checklist
Filters, belts, coils, drains, electrical parts, refrigerant circuits, economizers and heating sections are checked and recorded for each unit, with photos of anything that needs attention.
- 5
Written report
You get a written summary per visit: what was done, what is wearing, and priced recommendations. Owners and property managers can get copies for their records.
Typical prices
What commercial HVAC maintenance costs in Pasadena
Maintenance pricing depends on the number and size of units, visit frequency, filter types and roof access. Programs with several units on one roof cost less per unit than scattered single units. These are typical 2026 ranges in the Pasadena area, and we quote the full program price before we start the work.
| Job | Typical range | What is included |
|---|---|---|
| Rooftop unit, up to about 5 tons | $147 to $219 per visit | Full checklist including filters, belts, coil inspection, drains and electrical |
| Rooftop unit, larger sizes | $197 to $297 per visit | More filters, larger belts and longer coil cleaning time per unit |
| Restaurant make-up air unit | $167 to $283 per visit | Burner, blower, belts, filters and the interlock with the hood exhaust |
| Filter-only visit | $59 to $117 per unit | Filter changes between full visits, filters priced by size and type |
| Condenser coil deep cleaning | $187 to $437 per unit | Chemical coil cleaning when rinsing alone does not remove buildup |
Roof access without a fixed ladder, high-efficiency filters, older units with heavy wear and after-hours visit times change the price. Repairs found during maintenance are quoted separately, and program members get priority scheduling when a unit fails. Compare other jobs in our Pasadena HVAC price guide.
Commercial maintenance in Pasadena
Rooftop units in Pasadena face a hard environment. Summer afternoons in the high 90s, and sometimes over 100, mean condenser coils sit above a hot roof all day. Fall Santa Ana winds blow dust and leaves into coils and filters. During wildfire smoke events, like the weeks around the January 2025 Eaton Fire, filters on rooftop units can load up within days, and coils can collect fine ash. A maintenance program with flexible filter changes handles these swings better than a fixed calendar alone.
Pasadena's commercial areas, including Old Pasadena, the Playhouse District, and the stretches along Colorado Boulevard, Lake Avenue and East Foothill Boulevard, include many older buildings with rooftop units added over time on varying curbs, ducts and electrical supplies. Pasadena businesses get electricity from Pasadena Water and Power, while many nearby cities use SCE, so ask about current utility programs for efficient commercial equipment and controls.

Questions
Commercial HVAC Maintenance questions from Pasadena homeowners
Most restaurants do best with quarterly maintenance visits and monthly filter changes. Grease and cooking residue coat filters and coils much faster than in an office, and make-up air units have burners, belts and filters that need regular checks. Busy kitchens with long hours sometimes need filters changed more often. We set the schedule after the first visit and adjust it based on what the filters and coils show.
Usually not. Most work happens on the roof, and filter changes take a few minutes per unit. When a unit has to be shut down for longer, such as for coil cleaning, we schedule it before opening, after closing or during a slow period. We call the manager before every visit to confirm timing and access.
Yes. Every visit produces a written summary for each unit with what was done, readings, photos of concerns and priced recommendations. Many commercial leases require tenants to maintain HVAC equipment and keep records, and these summaries cover that. We can send copies to the tenant, the property manager and the owner, so everyone has the same information.
An economizer is a set of dampers on a rooftop unit that brings in cool outdoor air for cooling when conditions allow, so the compressor runs less. They often stick. Stuck open in summer, they let hot air into the building and overwork the unit. Stuck closed, they waste free cooling on cool evenings. We check the dampers, actuator and sensor at every visit.
Yes. We record each unit's filter size and type during the first survey, bring the filters with us, and change them at each scheduled visit. If your building needs filter changes between full visits, we add filter-only visits at a lower price. During smoke events or after Santa Ana wind days, you can call to add an extra change.
