AIS – Be Warm. Be Cool. Be Comfy.

Established in 2008, we are a small family owned and locally operated business based in the San Francisco Bay Area. We’ve built our company on the belief that working with a smaller heating and air company (HVAC) gives both the homeowner and the business owner the best in customer service. Every job gets our full attention and as owners, we personally oversee the quality of each job we complete.

Our Reputation

Our reputation in the community is built on quality workmanship, superior service and dedication to helping our customers maximize their energy usage at the lowest cost. Owner Daniel Sojkic has designed and installed over 2,000 heating and air projects throughout his career, and he’s proud to have trained some of the finest HVAC repair and installation experts in the region.

It’s our goal to find out exactly what you need to heat or cool your home or business – whether it is servicing your existing equipment or designing and installing a heating or cooling system – we do it all.

Our Straight-Forward Pricing

We offer straight-forward pricing to our clients so you’ll know the price before we begin any work. Our company is based on referrals so we work hard to make you feel as comfortable as possible with the entire process. We also provide performance guarantees for your new system so you know you will get what you expect and deserve from your system.

Our Services

AIS services all brands of heating and air conditioning systems. In addition to scheduled service checks, repairs of existing equipment and installation of new equipment and complete systems, we can help you find ways to reduce your energy bills using our thorough cost-benefit analysis.
