Equipment selection
Sized from the load and the ductwork you actually have, not copied off the old data plate. We tell you where a like-for-like swap is the right answer and where it is not.
Commercial HVAC & refrigeration
Everything on the roof, in the ceiling, behind the kitchen and inside the cold room — serviced, repaired and replaced by one contractor who documents the work.
Rooftop packaged units
The unit that runs everything
Most Valley commercial buildings are conditioned by packaged rooftop units, and most of them are worked far harder than the design ever assumed. Summer ambient in the 100s, agricultural dust on every coil, and a curb that has been resealed by three different trades.
- DiagnosticsFind the actual faultPressures, superheat and subcool, amp draws, capacitor and contactor condition, board and sensor faults — recorded, not guessed.
- RepairsCompressors to economizersCompressor and condenser fan motor replacement, coil leak repair, blower and belt work, economizer actuators and dampers that have seized open or shut.
- RefrigerantCharge handled properlyLeak search before top-up, recovery and recharge to manufacturer weight, and EPA-compliant handling and record-keeping on every system.
- Curbs & accessRoof left watertightCurb adapters, duct transitions and flashing done as part of the job, not left for someone else to discover in the first rain.
Commercial refrigeration
Cold rooms, cases and condensing units
Refrigeration failure has a clock on it. Product starts degrading long before anyone notices a number on a wall display, which is why a drifting box is an emergency even when nothing has actually stopped.
- Walk-in coolers and freezers
- Reach-ins, prep tables, undercounters
- Remote and self-contained condensing units
- Display and merchandiser cases
- Defrost faults, icing and drain-line blockage
- Door seals, closers, strip curtains and heaters
- Temperature controllers and alarm set-up
- Leak search, recovery and recharge
Ventilation & make-up air
When a building fights itself
Doors that are hard to pull open, a kitchen that smokes back into the dining room, a restroom that never clears: that is almost always a pressure problem, not a fan problem. Exhaust without matched make-up air pulls conditioned air out of the space and money out of the meter.
- Kitchen exhaustHoods, fans and curbsHood exhaust fans, belt and bearing service, grease containment, and fan replacement sized to the hood rather than to what was there before.
- Make-up airPut back what you take outMake-up air units serviced, commissioned and interlocked to the exhaust so the space stays close to neutral while the line is running.
- General exhaustRestrooms, stores, shopsInline and wall-mounted exhaust, warehouse ventilation, and controls so fans run when the space is occupied instead of around the clock.
- Air balancingMeasured, then adjustedAirflow readings at the grilles, damper and belt adjustment, and a written before-and-after so you can see what changed.
Controls & thermostats
Half of a comfort problem is a schedule problem
We find buildings running full cooling overnight, sensors reading the wrong zone, and thermostats locked out by a code nobody has any more. Fixing the control is often cheaper than anything mechanical and shows up on the next bill.
- Commercial thermostat replacement, programming and lockout
- Occupied and unoccupied schedules matched to your actual hours
- Zone sensor faults, wiring, transformers and relays
- Economizer control and free-cooling changeover set correctly
- Service and repair work alongside an existing BMS
Changeouts & projects
Replacement, planned like a project
A rooftop changeout is a crane, a permit, a power isolation, a curb adapter and a closing shift — and a building that has to be open the next morning.
Permits & Title 24
Permit pulled, Title 24 documentation prepared, inspection scheduled, and the closed permit handed over with the job file.
Lift & logistics
Crane or boom lift booked, roof protection down, street or lot access arranged, and the swap staged so the site loses as little trading time as possible.
Multi-unit programmes
Where a site has ten ageing units, replacing them in a planned sequence over a season beats replacing them one emergency at a time.
Tenant improvement
New ductwork, diffusers, zoning and equipment relocation when a space is being fitted out or reconfigured for a new tenant.
Efficiency upgrades
Economizer repair, control strategy, high-efficiency replacement and the paperwork for available utility rebate programmes on qualifying equipment.
Sectors
What breaks depends on the building
The failure modes, the access, and the cost of downtime are different in every one of these. So is the way we schedule the work.
Packing houses & cold storage
Dust-loaded condensers, long refrigeration runs, and a season that does not tolerate downtime. Pre-season condition surveys are worth more here than anywhere else.
Restaurants & food service
Hood exhaust and make-up air, walk-ins, prep refrigeration and a dining room that has to hold temperature through a 105°F afternoon. Work scheduled between services.
Retail & grocery
Display cases, back-of-house coolers, entry-door pressure and multiple rooftop units on different schedules. Repairs staged so the floor stays open.
Offices & medical
Zone comfort complaints, ventilation rates, filtration, and quiet work in occupied space — including early-morning and after-hours access.
Warehouse & light industrial
High-bay heat, exhaust and evaporative ventilation, office and QA rooms inside the shell, and equipment that is awkward to reach without a lift.
Schools & municipal
Work planned into holidays and weekends, documentation for facilities records, and package units that have to survive another year until budget arrives.
Emergency service
What to do when it goes down
Call, and tell us what the equipment is doing rather than what you think is wrong — the noise, the temperature, whether the fan is turning, what the display says. It usually tells us what to put on the truck.
We give you an arrival window on the phone. If we cannot get there fast enough to be useful, we say so on that call instead of letting you wait.
- Before you callCheck the obviousBreaker, disconnect switch, thermostat mode and batteries, and whether a filter or coil is visibly blocked. It is free and it is sometimes the whole answer.
- RefrigerationProtect the product firstKeep doors shut, move what you can to another box, and log the temperature. Tell us the reading when you call.
- PriorityAgreement sites go firstMaintenance-agreement customers are dispatched ahead of the general queue, and we already know their equipment.
