About Us

At Ultra Heating & Cooling, we believe you shouldn't have to sweat through a summer or shiver through a winter just to find an HVAC technician you can trust. As a small, locally owned business right here in Galt, CA we don't look at our clients as account numbers—we look at you as our neighbors, because you are.

Founded by Jonathan Castillo, Ultra H&C was built on a simple philosophy: provide top-tier heating and cooling expertise without the big-city corporate games or high-pressure sales tactics. Whether its a routine AC tune-up, or a full system upgrade to keep your utility bills low, our team brings local pride and reliable service to every single doorstep.

We live where you live, we breathe the same air, and we treat your home's comfort exactly like we would our own. Thank you for keeping it local and letting us keep you comfortable!
