Services
Serving Businesses and Homes Across Santa Barbara County
At SMI HVAC Services, we provide comprehensive HVAC services to both commercial and residential clients across Santa Maria, Santa Barbara County, and surrounding communities. From commercial air conditioning to residential furnace repair, our work is defined by professionalism, precision, and a deep respect for our clients’ time, property, and budget.

Our team is fully licensed, insured, and trained to manage complex HVAC systems, including those in high-demand environments like restaurants, labs, apartment buildings, and large estate homes. We do not offer free estimates, because we believe in quoting only what’s necessary — based on an on-site assessment, not guesswork.
We offer financing options through FTL Financing to make large-scale repairs and system replacements more accessible without compromising on quality or reliability.
Commercial HVAC Services
Our primary focus is commercial HVAC. We understand the operational needs of business environments — and the cost of downtime when systems fail. That’s why we offer fast, honest, and high-performance service across all major commercial systems.
Commercial Air Conditioning
We install, repair, and maintain commercial-grade cooling systems for a wide range of buildings. Whether you operate a hotel, lab, or restaurant, we ensure your system meets the capacity and compliance standards of your space. Emergency response and preventative maintenance plans are available.
Commercial Heating
From office buildings to multi-unit housing complexes, we provide full-service commercial heating support — including diagnostics, repair, retrofits, and installation. We handle boilers, rooftop units, and commercial furnaces, ensuring consistent heating performance when it matters most.
Commercial Refrigeration & Ventilation
We install and maintain restaurant refrigeration systems, ventilation hoods, exhaust systems, and air purification equipment. We also provide airflow balancing and ductwork optimization for labs and healthcare facilities, ensuring safe, regulated air circulation.
Duct & Ventilation Services
Airflow, efficiency, and indoor air quality all rely on the condition of your ducts and ventilation systems. We offer both residential and commercial duct and vent services to improve safety, system performance, and health outcomes.
Duct Inspection & Cleaning
Dirty, clogged, or leaking ducts can increase your energy bills, reduce HVAC efficiency, and worsen indoor air quality. Our duct cleaning services use professional-grade equipment to remove debris, dust, mold, and other contaminants. We also inspect for leaks or structural issues and make recommendations for repair or sealing.
Dryer Vent Cleaning
Dryer vent cleaning isn’t just for performance — it’s about safety. Lint buildup is a leading cause of dryer fires in homes and businesses. We offer thorough, scheduled dryer vent cleaning to reduce risk and keep your equipment running smoothly, especially important for apartment buildings or properties with shared laundry facilities.
Residential HVAC Services
While our focus is on commercial HVAC, we proudly offer select residential services for local homeowners — particularly those operating high-performance systems or living in larger homes that require commercial-grade support. We also prioritize helping senior homeowners who need reliable service without pressure or upselling.
Residential Air Conditioning
Whether you're running a standard central AC or a complex, multi-zone system, we provide repair, replacement, and maintenance tailored to your home’s cooling needs. Our service is discreet, clean, and always respectful of your space.
Residential Heating
We diagnose and repair heating systems quickly — including gas furnaces, heat pumps, and hybrid units. When a full system replacement is necessary, we help you choose an energy-efficient option and offer financing to ease the process.
Residential Repairs & Maintenance
Regular maintenance helps you avoid emergencies and keeps your system running at its best. We offer seasonal tune-ups, filter replacements, performance diagnostics, and full-system inspections — so you can avoid breakdowns when you need heating or cooling most.
Financing Through FTL Financing
Big HVAC projects can come with big costs — especially in commercial environments or during system replacements. That’s why SMI HVAC Services partners with FTL Financing to offer flexible payment options for qualifying clients.
Whether you're a business owner investing in a rooftop unit or a homeowner replacing a furnace, financing helps you get the solution you need without putting off necessary upgrades. Our team will walk you through available terms, eligibility requirements, and the application process.

- We do the job right the first time.
- We charge only for what’s necessary.
- We explain everything clearly.
- We leave your property clean and your system better than we found it.
