Emergency repair & turnarounds: Rapid dispatch, diagnosis, and safe return-to-service procedures.
-
Energy & water optimization: Retro-commissioning, controls tuning, water treatment, and rebate guidance.
We understand the unique infrastructure needs of Arizona’s climate, industries, and regulatory environments. Our mechanical systems are designed with longevity, efficiency, and ease of service in mind—because we know a reliable system means fewer interruptions and greater peace of mind.
Systems we design, install & maintain
-
Commercial HVAC: air handlers, VAVs, rooftop units, heat pumps, VRF/VRV, IAQ/filtration, and economizers.
-
Central plants: chillers (air/water-cooled), boilers (steam/hot water), cooling towers, pumps, heat exchangers.
-
Process & utility piping: carbon/stainless/stainless-sanitary, welded/fused systems, steam/condensate, hydronic, glycol.
-
Compressed air & specialty gases: dryers, receivers, distribution, leak audits, purity monitoring.
-
Plumbing & drainage: domestic/process water, backflow prevention, RPZ testing, trench drains, grease interceptors.
-
Controls/BAS: integration, graphics, alarming, and KPIs for visibility and efficiency.
Built for Arizona conditions
-
High heat & UV: equipment selection, coatings, and shading that protect assets and reduce derating.
-
Dust & air quality: filtration strategies, coil protection, and cleaning intervals that keep systems efficient.
-
Monsoon readiness: sump capacity, drainage, and control sequences that manage rapid swings in temperature and humidity.
-
Water stewardship: tower treatment, blowdown control, submetering, and make-up water monitoring.

FAQs
What’s included in a typical PM agreement?
Filters and belts, coil cleaning, drain maintenance, lubrication, vibration checks, water-treatment testing, controls review, and seasonal changeovers—customized to your equipment list.
Do you work in active facilities without shutdowns?
Yes. We phase tasks, schedule off-hours work, and provide temporary services to keep production and occupants protected.
Can you integrate with our existing BAS/controls?
In most cases. We support common platforms and provide graphics, trending, and alarms for visibility and reporting.
How do you handle compliance and permits?
We coordinate permits, inspections, and documentation and align work to applicable codes and standards (e.g., mechanical/plumbing codes, NFPA, ASHRAE guidance).
Do you service cooling towers, boilers, and chillers?
Yes—full central-plant service including pumps, towers, boilers, chillers, and associated water treatment.
Can you help reduce energy and water costs?
We identify low-cost control changes, schedule optimization, setpoint strategies, and utility-incentive opportunities, then verify results with trend data.
Where do you operate?
We’re based in Phoenix and serve commercial and industrial clients across Arizona.
