Commercial Air Conditioning

AC Solutions Built for Commercial Demands

At SMI HVAC Services, we understand the pressures of running a business — and how critical a reliable air conditioning system is to your daily operations. Whether you're managing a busy restaurant, a high-occupancy apartment complex, or a precision-controlled laboratory, your cooling system needs to perform without fail.



Our team specializes in commercial air conditioning solutions for clients across Santa Maria, Santa Barbara County, and neighboring areas. From rooftop unit installations to emergency repair and seasonal maintenance, we provide reliable service backed by years of hands-on experience — always with a focus on integrity, not upselling.

Commercial Cooling Services We Offer

We deliver full-service commercial air conditioning solutions for buildings of all sizes. Services include:

AC Installation & System Design

We install commercial-grade cooling systems tailored to your building’s square footage, usage, and zoning needs. Whether you're retrofitting a system in an older building or installing brand-new rooftop units, we build a solution that meets your load requirements and budget.

AC Repair

We diagnose and repair all major commercial AC brands and systems — from rooftop units and split systems to packaged and ductless configurations. If your system is making noise, blowing warm air, short cycling, or causing unexpected utility bills, we’ll get to the root of the issue fast.

Preventive Maintenance

Regular maintenance reduces the risk of costly breakdowns. Our commercial HVAC maintenance programs include seasonal inspections, coil cleaning, refrigerant checks, electrical testing, and performance diagnostics — all scheduled around your business needs.

Emergency HVAC Response

When AC systems fail during business hours, every minute matters. We prioritize commercial emergencies with prompt scheduling and professional communication, minimizing downtime and protecting your tenants, customers, or employees.

Designed for Commercial Environments

Not all HVAC companies are equipped to handle the scope and urgency of commercial work. At SMI HVAC Services, we specialize in systems built for:



  • Hotels & hospitality properties – Comfort, quiet operation, and multi-zone control for guest satisfaction
  • Restaurants & food service – Reliable cooling for dining spaces, kitchens, and refrigeration-adjacent systems
  • Labs & medical facilities – Precise temperature regulation, filtration, and system redundancy
  • Offices & retail – Quiet, consistent performance to keep employees and clients comfortable
  • Apartments & multi-unit buildings – Efficient cooling for shared spaces and unit-specific zones


We work with property managers, facility directors, and business owners directly — always providing clear communication, written proposals, and accountability from start to finish.

Why Commercial AC Fails — and How We Fix It

Commercial systems face unique wear and tear. Issues we regularly diagnose and resolve include:



  • Dirty or clogged condenser coils
  • Failed capacitors or motors
  • Refrigerant leaks or low charge
  • Thermostat miscalibration
  • Faulty electrical components
  • Airflow restrictions in ductwork or filters
  • Sensor failures in multi-zone systems


Because many systems run nonstop during business hours — or even 24/7 — maintenance is essential. We help you stay ahead of major repairs by catching minor problems early and offering practical recommendations without pushing unnecessary upgrades.

Real-World Results, Not Sales Gimmicks

We don’t offer free estimates. Instead, we provide accurate, site-specific evaluations and clearly outline your options. Our goal is to build long-term relationships with our commercial clients by showing up on time, doing the work right, and respecting your bottom line.


You won’t get vague advice or one-size-fits-all packages. Every building is different — and we treat it that way.

Financing Available for Commercial AC Projects

Replacing or upgrading a commercial cooling system is a significant investment — especially when working within budget constraints. We offer financing through FTL Financing to make large projects more accessible and easier to manage.



Whether you're planning a system overhaul or facing an unexpected replacement, our team can walk you through your financing options and help structure a payment plan that works for your business.
