Residential Air Conditioning

Stay Cool With Reliable Home Cooling Solutions

When California summers hit, your air conditioning system becomes more than just a luxury — it’s a necessity. Whether you live in a traditional single-family home, a senior residence, or a large estate that operates on commercial-grade equipment, SMI HVAC Services delivers air conditioning services that are professional, precise, and performed with integrity.



As a family- and minority-owned HVAC company based in Santa Maria, we serve homeowners across Santa Barbara County and beyond with practical, efficient cooling solutions. We don't offer free estimates — we offer real evaluations and honest service, every time.

Our Residential Air Conditioning Services

We offer a full range of residential AC services to keep your home comfortable and your system running efficiently, no matter its size or complexity.

AC Installation & Replacement

Whether you're installing a new unit or replacing an outdated system, we design AC solutions tailored to your home’s size, layout, and cooling demands. We install:



  • Central air conditioning systems
  • Commercial-grade units for large residential estates
  • Multi-zone systems for multi-level homes
  • High-efficiency models for energy-conscious homeowners


We calculate load requirements, evaluate ductwork, and recommend systems that meet both performance and budget expectations — without overpromising or overselling.

AC Repair

If your AC is blowing warm air, making unusual noises, leaking water, or causing energy bills to spike, we’ll diagnose the problem and provide clear, practical solutions. Our technicians service all major makes and models, and we respond quickly to minimize downtime and discomfort.



Common repair calls include:

  • Refrigerant leaks
  • Frozen evaporator coils
  • Faulty thermostats
  • Dirty condenser coils
  • Blown capacitors or electrical issues
  • Airflow problems


We focus on fixing the issue — not pushing unnecessary upgrades.

AC Maintenance

Regular maintenance prevents expensive breakdowns and keeps your system running at peak efficiency. Our seasonal tune-ups include:



  • Full system performance check
  • Filter inspection and replacement
  • Condenser and evaporator coil cleaning
  • Refrigerant level check
  • Thermostat calibration
  • Electrical safety testing


We recommend at least one AC tune-up per year, especially before peak summer use.

Specialized Services for Large Homes

Some homeowners have properties that exceed typical residential demands. We work with clients who live in:



  • Custom estate homes
  • Multi-zone residences
  • Multi-level properties
  • Residential buildings using commercial-grade HVAC systems


These homes often require commercial-level cooling equipment — and not every residential HVAC provider is qualified to handle that scale. Our experience with large-format systems ensures your cooling solution is properly sized, installed, and supported long-term.

Signs Your AC System May Need Service

Not sure if your air conditioner is working as it should? Call us if you notice:



  • Uneven temperatures throughout your home
  • Short cycling (turning off and on too frequently)
  • Weak airflow from vents
  • Strange smells or sounds during operation
  • Rising electricity bills despite normal usage
  • System age over 12–15 years


We’ll perform a full evaluation and provide honest feedback on the condition of your system — no scare tactics, no inflated quotes.

Respectful Service for Senior Homeowners

We proudly serve senior homeowners throughout Santa Maria and surrounding counties. Our technicians take the time to explain system issues clearly, offer honest recommendations, and provide service with respect and care — never pressure or confusion.


We understand that many seniors live on fixed incomes and want only what’s necessary. That’s exactly what we deliver.

FTL Financing Available

Need a system replacement or major repair but concerned about upfront costs? We offer financing through FTL Financing to help homeowners invest in the cooling comfort they need — without breaking the budget.



Our team will walk you through the application process and financing terms so you can move forward with clarity and confidence.
