But after a long day of fun in the sun, there’s nothing better than returning to a cool, comfortable home.

Whether your goals are to increase your home comfort, reduce your energy consumption, or lower your utility bills, we can help you achieve them! Our team will listen to your concerns, evaluate your current HVAC system, and then recommend a solution based on your unique needs.  

We offer a wide selection of premium HVAC and home performance products, including heat pumps, water heaters, tankless water heaters, air purifiers, ductless mini splits, air conditioners, furnaces, thermostats, and much more.

The Hassler Difference 

Here at Hassler, we look at the home as a system. Rather than simply address the problem in one room with a quick fix, we take the entire home into consideration and provide HVAC upgrades that will resolve the underlying issues so that you can enjoy greater efficiency, comfort, and energy savings season after season. 

As part of our commitment to going green, we’re proud to promote local and federal incentives to help homeowners improve their home’s energy efficiency, and one such program is PACE financing. 

Through PACE, financing can be repaid over time through property taxes, making it one of the most affordable ways for homeowners to improve their home’s energy efficiency.

Does your HVAC system need an upgrade? The Hassler team is here for you. Call (510) 288-5563 or contact us today to learn more about the HVAC installation, repair, and maintenance services we offer to homeowners in Hercules.
