Built for Business

Your Local HVAC Contractor for Businesses

Running a commercial facility means you cannot afford downtime when your climate control system fails. As an experienced HVAC contractor for businesses across El Dorado County, Placerville, and El Dorado Hills, we handle the full scope of commercial work: system installation, diagnostics, repairs, and ongoing maintenance. Our team understands the demands of commercial environments and shows up ready to size up the issue and get your operation back on track fast.

What We Do

Commercial Heating and Cooling Solutions That Cover Every Need

Our commercial services go well beyond standard HVAC repair. We install and service business air conditioning systems, commercial heating solutions, and industrial cooling systems for a wide range of facility types. We also specialize in custom metal fabrication for commercial kitchen hoods and industrial ventilation, a capability few local contractors can match. From a small office in Diamond Springs to a larger commercial kitchen in Folsom, we bring the same level of precision and professionalism to every project.

Certified Expertise

HVAC SERVICES Applied to Commercial Work

Smit's holds one of the highest designations available in the HVAC industry. That certification is not just for residential jobs. We apply that same level of technical skill to commercial heating solutions and advanced ductless system installations for businesses throughout the region. When your facility needs a system that performs reliably through California's hot summers and cold winters, you want a contractor who has earned the industry's top credential, not just a general handyman with a truck.

Stay Ahead of Breakdowns

Common Questions

Answers About Our Commercial HVAC Services

  • What areas does Smit's Solar Heating and Air Conditioning serve?

    Smit's is based in Diamond Springs, CA and proudly serves homeowners and businesses throughout El Dorado County. Our primary service area includes Diamond Springs, Placerville, El Dorado Hills, and Folsom, along with the broader Tri County foothills region. If you're unsure whether we serve your location, contact our team and we'll be happy to help.
  • How long has Smit's been in business, and why does that matter for me as a customer?

    Smit's has been continuously operating since 1972, giving us over 54 years of experience in the Sierra foothills HVAC and solar market. That tenure means we have worked on virtually every type of system in the region and understand the specific demands of the local climate. For customers, it means working with a team that has a long, verifiable track record in your community, not a new company that may not be around next year when you need follow-up service or warranty support.

  • What is a Mitsubishi Diamond Contractor and why does it matter when hiring an installer?

    The Mitsubishi Diamond Contractor designation is one of the highest certifications available for contractors who install and service Mitsubishi equipment. It requires advanced technical training and a demonstrated record of quality installations. For homeowners, it means the technician working on your system has been trained to the manufacturer's highest standard, which can affect both system performance and the validity of any manufacturer warranty. Smit's holds this status, making us one of the most qualified Mitsubishi installers in El Dorado County.
  • My swamp cooler is not keeping up anymore. What are my options?

    This is a common concern for El Dorado County homeowners as summers get hotter. If your evaporative cooler is no longer providing adequate cooling, you may be a good candidate for an upgrade to an integrated air conditioning system or a high-efficiency Mitsubishi heat pump. These modern systems provide both heating and cooling in one unit and are significantly more effective in extreme heat. Our team can assess your current setup and walk you through the options, including financing, so you can make the right decision for your home and budget.
  • Does Smit's offer a maintenance plan to keep my system running year-round?

    Yes. We offer a tiered Preferred Customer maintenance membership program that includes routine system inspections and service discounts for members. Regular maintenance is one of the most effective ways to extend the life of your HVAC equipment, catch small issues before they become costly repairs, and keep your system running efficiently through both the summer cooling season and the winter heating season. Contact us to learn more about the available membership tiers and what is included at each level.
  • Can Smit's help with backup power if the electricity goes out?

    Absolutely. We install and service Generac whole-house backup generators and handle transfer switch installation to ensure your home stays powered safely during outages. Power outages in the Sierra foothills can happen unexpectedly, especially during storm season or high-demand periods on the grid. A properly installed backup generator gives you peace of mind that your heating, cooling, refrigeration, and other essentials will keep running regardless of what happens to the grid. Call or text us to discuss your backup power options.
  • Do you offer financing for new HVAC systems or solar installations?

    Yes, financing options are available for qualifying customers who need help managing the upfront cost of a new heating and cooling system, solar installation, or other major equipment upgrade. High-quality HVAC and solar systems represent a significant investment, and we want to make sure cost is not a barrier to getting the right solution for your home. Reach out to our team to learn more about current financing options and what may be available for your specific project.
  • Does Smit's handle commercial HVAC work, or is the focus mainly residential?

    We handle both. While the majority of our work is residential, we do take on commercial HVAC projects as well. Our commercial capabilities include specialized services like custom metal fabrication for commercial kitchen hoods and industrial ventilation systems. If you have a commercial facility in El Dorado County that needs HVAC work, give us a call to discuss your project and we can let you know how we can help.
