Our Services – Organized for Your Needs
Our wide range of HVAC services is structured with our core commercial clientele in mind, followed by duct and air quality services, and finally, high-integrity residential support.
Commercial HVAC Services
Commercial Air Conditioning
We install, service, and repair large-scale cooling systems designed to serve businesses such as hotels, labs, restaurants, offices, and apartment complexes. Our technicians understand the urgency and complexity of commercial cooling demands.
Commercial Heating
Whether you're running a multi-unit apartment building or a high-traffic restaurant, your heating system needs to be dependable. We work on boilers, furnaces, and commercial heat pumps to ensure safe and consistent heating.
Commercial Refrigeration & Ventilation
For businesses that rely on specialized cooling or air control — such as walk-in coolers, ventilation hoods, or lab-grade air circulation — we provide full-service installation, repair, and compliance-driven solutions.
Duct & Vent Cleaning Services
Duct Inspection & Cleaning
Dust, mold, and debris can compromise airflow and air quality. We inspect and clean your ductwork with industry-grade tools to help your HVAC system operate efficiently and your indoor air stay clean.
Dryer Vent Cleaning
Clogged dryer vents are a leading cause of preventable fires. We offer professional dryer vent cleaning for both residential and commercial properties, keeping your system safe and efficient.

We serve upscale homes, including those with commercial-grade cooling systems. Whether you need repair, maintenance, or a full replacement, we offer tailored solutions to match your home and lifestyle.

Why HVAC Integrity Matters
In any property — commercial or residential — HVAC systems aren’t just about comfort. They affect productivity, health, safety, and long-term financial efficiency. When a restaurant loses refrigeration, or a lab suffers from poor ventilation, the consequences are immediate and costly. In homes, a failed AC or heater can pose real health risks, especially for seniors or young children.
At SMI HVAC Services, we take these responsibilities seriously. We don’t rush jobs, and we don’t cut corners. Every solution we recommend is based on the actual condition of your system and your building’s needs — not sales goals.

SMI's team is fantastic. I'm in charge of a large multi campus church with with 35 units. We had Russ and his team replace some duct smoke detectors when other contractors failed. We also had them repair a few other units I'm calling SMI first from now on. They get it done!
