Cooling Problems Fixed Without Shutting Your Doors
Scheduling That Fits Your Hours
Restaurants get us before the lunch rush. Offices get us at 7 a.m. Warehouses get us on a Saturday. Tell us your window and we build the visit around it.
Quiet, Clean, and Out of the Way
No blocked entrances, no tools across a sales floor, no crew standing around in view of your customers. We stage on the roof or in back whenever the building allows.
Roof Work Done Safely
Ladder tie-offs, proper roof access, curb and flashing left the way we found them. A repair that causes a leak next winter is not a repair.
Documentation Your Office Can Use
Unit numbers, readings, parts, and photos on every report. If you manage several buildings, you get history per unit instead of a stack of loose receipts.
What People Say After the Truck Leaves
"Our dining room rooftop went down at 11 a.m. on a Friday. They had a tech on the roof within a couple hours, found a seized fan motor, and we never closed."
"We run three buildings and they track every unit by number. When something fails they already know what is up there and what we replaced last time."
"Professional crew, badged in properly, kept the noise down in a medical suite, and finished before patients arrived. Billing matched the quote exactly."
Rooftop Unit Down? Get a Tech Scheduled.
The commercial diagnostic is $125. A tech inspects the unit, finds the fault, and hands you a written repair price before anything gets ordered or opened up.
How We Handle Commercial AC Repair
Commercial cooling fails differently than residential. The equipment is bigger, it runs longer, and when it quits the cost is not just discomfort. It is a dining room emptying out, a server closet climbing past 90, or a crew of employees who cannot focus. So the first thing we ask on the phone is what the building does and what happens if the space stays warm, because that decides how fast we push the schedule.
Most of what we service around here is rooftop package units, plus split systems in older storefronts and mini splits in offices carved out of warehouse space. Before a tech climbs down, these get checked:
- Economizer operation and dampers, which fail stuck open more often than owners realize and drag hot outside air straight into the space.
- Belts, sheaves, and bearings on belt driven blowers, since a glazed or loose belt shows up as weak airflow long before it snaps.
- Contactors, capacitors, and compressor amp draw on each stage, because multi stage units often lose one stage quietly and still blow cool air.
- Coil condition on both sides, plus the filter rack, which on a busy building can load up in weeks rather than months.
- Condensate drains, pans, and roof drainage, so a clogged pan does not send water through a ceiling tile onto product.
- Curb, flashing, and unit disconnect condition, noted on the report even when they are not part of the current repair.
What commercial equipment runs into locally
Rooftop units bake up here. A dark roof in Highland can run well over 150 degrees on a July afternoon, and equipment sitting in that all day sheds capacitors, cooks wiring insulation, and pushes head pressure high enough that a marginally dirty coil becomes a hard shutdown. Along the Palm Avenue corridor and out in the Colton industrial pockets off Valley Boulevard we also deal with heavy dust, which loads filters and outdoor coils fast on units pulling large volumes of air all day.
The second pattern is deferred maintenance stacking up. A building changes property managers, service lapses for two seasons, and then three units fail in the same month. When we walk a roof like that we give you a priority list instead of one giant number. What has to be fixed today, what should be scheduled this quarter, and what is fine to watch. You decide the pace and the budget.
What a service call looks like
- 1
Scope the Call Before We Roll
We confirm unit count, roof access, ladder or lift needs, badging, and your operating hours so the tech arrives with the right equipment and the right approval.
- 2
Diagnose the Specific Unit
Units get identified by tag or location so the report matches your records. Electrical, airflow, and refrigerant side all get checked in order.
- 3
Written Price Before Parts
You get the fault, the part, the cost, and the lead time. If a part has to be ordered, we tell you what temporary options exist in the meantime.
- 4
Repair During Your Window
If the fix cannot happen without noise or an entry blocked, we schedule it for before open, after close, or a slow stretch you pick.
- 5
Verify and Document
Post repair readings, supply temperature at the diffusers, photos of the work, and the report sent to whoever handles your invoices.
Ongoing service and budgeting
Most buildings we service move to a scheduled plan after the first emergency. Two visits a year per unit, filters on a set interval, belts and drains checked before the season turns, and a written condition report you can hand to ownership at budget time. It costs less than the overtime calls it replaces, and it makes replacement planning predictable instead of urgent.
When a unit finally reaches the end, we lay out repair cost against replacement cost with the expected remaining life on the equipment, including what a new unit would do to your monthly power draw. No pressure and no commissioned salesperson in the mix. Businesses across Highland, San Bernardino, Colton, Loma Linda, Redlands, and Riverside stay with Highland Heating & Air because the recommendation matches what we would do with our own building.

Commercial AC Questions, Answered
It is $125 per visit, and that covers the inspection of the unit that is down plus a written repair price. If several rooftop units need looking at on the same trip, tell us up front and we will quote the walkthrough as one visit instead of stacking fees.
Yes. Restaurants along the Palm Avenue corridor usually take us between the lunch and dinner rush, offices take early mornings, and warehouses often prefer Saturdays. We answer the phone 24/7, 365 days a year, and there is no added night or weekend charge.
Rooftop units are most of our commercial work. We handle single and multi stage packages, economizers, belt driven and direct drive blowers, plus split systems and ductless units in offices built inside warehouse space.
On multi stage rooftop equipment that usually means one stage has dropped out, or the economizer is stuck and pulling in 100 degree outside air. It can also be a contactor chattering under high roof temperatures. It is a real fault, not the unit being moody, and it is worth catching before the compressor takes the hit.
Straight repairs generally do not. Changeouts, new curbs, gas line work, and electrical modifications do, and those go through the city or county having jurisdiction over your building. We handle the filing and the inspection so it does not land on your facilities manager.
Yes. We tag units by building and unit number and keep the service history per unit, so you can see what was replaced and when. Property managers running sites across Colton, Rialto, and Loma Linda usually get one consolidated report per visit cycle.
