Our Reputation

AIS has built a strong reputation in the Bay Area over the years. Our work is rooted in these three core values:

  • Quality workmanship: We believe in doing the job right the first time, every time. From installing new HVAC systems to completing complex repairs, we aim to exceed your expectations with our attention to detail and skilled craftsmanship.
  • Superior service: We don’t just show up, fix the problem, and leave. Our friendly team takes the time to understand your needs, explain your options, and ensure you’re thrilled with our work.
  • Dedication to maximizing energy efficiency: Whether through system upgrades, smart thermostats, or zoning solutions, we’ll help you reduce energy waste and lower your utility bills while keeping your home or business comfortable.

As a small business, we value relationships and always go the extra mile. Under the leadership of owner Daniel Sojkic, AIS has designed and completed over 2,000 HVAC projects in the Bay Area.

From small residential jobs to complex commercial projects, our team is well-equipped to handle it all. Daniel has also trained some of the finest technicians in the region, passing on his extensive knowledge and high standards.

Our customer-first approach ensures that you don’t just get new HVAC equipment—you get a system that works perfectly for your space.

Our Straightforward Pricing

At AIS, we provide clear, upfront estimates before the work begins, so you’ll never have to worry about unexpected costs. We take pride in making the entire process smooth and easy for our customers.

Referrals also mean the world to us, so we work hard to completely satisfy every customer. Plus, we offer performance guarantees so you can feel confident that your system will work as expected.

Our Services

We offer comprehensive HVAC services for residential and commercial properties. Trust us for the following: 

  • HVAC design and installation: Whether you need a new build or an upgrade, our team will work with you to design a heating and cooling system that fits your needs. Once the design is complete, our experienced technicians will handle the installation with care and precision.
  • HVAC repair: Our repair services cover everything from minor fixes to major malfunctions. We service all makes and models, ensuring your system runs smoothly and efficiently.
  • HVAC maintenance: Regular maintenance prevents breakdowns and extends your HVAC system’s lifespan. Sign up for routine maintenance to avoid unexpected issues and keep your home comfortable.
  • HVAC retrofit and replacement: When it’s time to upgrade, we offer optional retrofitting services to improve your current system without needing a full replacement. Then again, if your equipment is outdated or beyond repair, we’ll guide you through the replacement process.
  • Zoning systems: Zoning allows you to control the temperature in specific areas of your home so you don’t waste energy heating or cooling rooms you aren’t using. It also allows each room’s occupants to maintain the ideal settings for their comfort level.
  • Ductwork service: Clean, sealed, well-designed air ducts are essential for good indoor air quality and system efficiency. Our ductwork installation, sealing, and repair services leave you with air ducts that enhance HVAC performance rather than detracting from it.
  • Energy audits: Want to lower your utility bills? Start with an energy audit from AIS. We’ll evaluate how efficiently your home uses energy and recommend cost-effective solutions to reduce waste.

We offer free in-home estimates on HVAC replacements and installations from Bryant. Convenient financing options are also available with approved credit.
