Our Commercial Services

Let us set your business up for success as your one-stop shop for HVAC solutions.

Our commercial HVAC services include:

  • Installation: When your unit is outdated and increasing your monthly costs, let us help you reduce overhead with a new and improved system. Updated technology provides benefits like putting your HVAC unit on a schedule to prevent unnecessary usage.
  • Repairs: Anytime you notice an issue like over-cycling or foul odors coming from your HVAC system, it’s vital that you schedule a service right away to prevent these problems from growing.
  • Maintenance: We offer a bronze, silver, and gold maintenance plan to ensure your unit is taken care of. Preventative maintenance helps you avoid breakdowns, keep your warranty, and extend the lifespan of your unit.
  • Ductless mini-splits: For smaller commercial spaces, a ductless mini-split is an excellent choice if you need zoning or a supplemental system for constantly used spaces. Zoning is another excellent way to increase your energy efficiency and reduce costs.
  • Indoor air quality: Breathe easier and promote a clean atmosphere with our indoor air quality solutions. Improved filters or purification reduces airborne contaminants that reduce efficiency, spread illness, and increase cleaning requirements.

Our comprehensive commercial HVAC services in Orange County are here to set your business up for success with whatever you need to stay comfortable. No matter what you need, 20th Century Air is your one-stop shop.

Maximize Comfort and Efficiency with the Right HVAC Unit Size

Choosing the right size HVAC unit for your commercial space is crucial for maximizing comfort and energy efficiency. An undersized unit may struggle to keep up with the cooling or heating demands of your building, leading to uneven temperatures and increased energy consumption. On the other hand, an oversized unit may cycle on and off frequently, resulting in unnecessary wear and tear and higher energy bills.

Our team at 20th Century Air can perform a thorough assessment of your commercial space to determine the appropriate HVAC unit size for your specific needs. By selecting the right size unit, you can enjoy:

  • Consistent and comfortable indoor temperatures
  • Optimized energy efficiency
  • Lower utility costs
  • Extended system lifespan

Don't let an improperly sized HVAC unit compromise the comfort and efficiency of your commercial space. Contact us today to schedule a consultation and ensure that you have the right HVAC system in place.
