Commercial Heating

Reliable Heating for Demanding Commercial Environments

Heating failures in a commercial property aren't just inconvenient — they can bring operations to a halt. At SMI HVAC Services, we provide commercial heating solutions designed to meet the performance, safety, and reliability needs of hotels, labs, offices, restaurants, apartment complexes, and more.



We serve clients across Santa Maria and Santa Barbara County with a focus on responsive service, accurate diagnostics, and professional-grade system design. Whether you need routine heating maintenance, emergency furnace repair, or a full system replacement, our work is always performed with honesty, skill, and a strong sense of responsibility to your business.

What We Offer – Full-Service Commercial Heating

We handle everything your facility may need when it comes to heating. Our team works on most major makes and models, including large-format and high-capacity equipment.

System Installation & Replacement

We design and install heating systems tailored to your building size, layout, and usage. Whether it’s a rooftop unit for a retail center or a boiler replacement for a senior living complex, we ensure your new system meets code requirements, efficiency standards, and your internal operational needs.

Furnace & Heating Unit Repair

If your existing heating system is showing signs of failure — such as inconsistent temperatures, loud noises, delayed ignition, or high utility costs — our team will quickly diagnose and resolve the issue. We carry the tools and parts to repair rooftop units, furnaces, boilers, and more.

Heating System Maintenance

Preventive maintenance is the most effective way to extend system life, reduce energy costs, and avoid mid-season emergencies. We offer service contracts and seasonal tune-ups that include combustion analysis, airflow checks, component testing, and filter replacement — all scheduled around your business hours.

Emergency Heating Support

When heating fails during operating hours or overnight in a multi-unit building, time is critical. Our technicians prioritize commercial calls and work efficiently to restore comfort and functionality.

We Understand Commercial Systems

Commercial heating systems differ significantly from residential models in both complexity and scale. That’s why we don’t take a one-size-fits-all approach. We assess:



  • Load calculations based on occupancy and square footage
  • Zoning requirements for multi-use or multi-tenant buildings
  • Local code compliance and energy efficiency mandates
  • Access for serviceability and future expansion
  • Noise control needs for hospitality and office environments


Our experience spans a wide range of property types, including:

  • Hotels and motels
  • Food service and restaurant spaces
  • Clean rooms and medical labs
  • Professional office buildings
  • Multi-family and apartment complexes
  • Senior housing and assisted living facilities


Whatever your building type, we’ll ensure your heating system performs dependably in high-demand situations.

Common Heating Issues We Solve

Heating problems in commercial spaces can stem from a range of causes — often worsened by delayed maintenance or aging infrastructure. We regularly resolve:



  • Pilot light or ignition problems
  • Short cycling and overheating
  • Thermostat misreadings
  • Dirty burners or clogged filters
  • Leaky heat exchangers
  • Loud vibrations or fan failure
  • Inadequate airflow or unbalanced zones
  • Energy inefficiency due to outdated systems


When replacement is the most cost-effective solution, we’ll explain why, provide options, and never pressure you into unnecessary work.

We Don’t Cut Corners. We Earn Trust.

SMI HVAC Services does not offer free estimates — and we think that’s a good thing. Instead, we provide site-based evaluations that take real conditions into account. This results in better recommendations, fewer surprises, and systems that perform exactly as expected.



You won’t get vague advice or sales-heavy pitches. Just honest feedback, real solutions, and workmanship you can rely on long after the job is done.

Financing Available Through FTL

Replacing a rooftop unit, commercial boiler, or multi-zone furnace system isn’t always in the annual budget. That’s why SMI HVAC Services partners with FTL Financing to offer qualified commercial clients access to financing options that can help spread the cost of large-scale heating projects over time.



Whether you’re planning ahead or responding to an emergency replacement, we’ll walk you through available terms and eligibility.
