Our Journey To Better Air

Cooler Homes, Warmer Hearts.

You know that feeling when you walk into a room, and it’s just… perfect? That’s what sparked Eco Air Cooling and Heating LLC. We saw folks in San Mateo County wrestling with unpredictable temperatures and energy bills that made their eyes water. We thought, “There has to be a better way to bring real comfort without costing the Earth or a fortune.” So, we rolled up our sleeves. We set out to be more than just an HVAC contractor; we wanted to be partners in creating genuinely comfortable, healthy homes. That means guiding you to the right high-efficiency heat pumps, maybe suggesting how a smart thermostat, like an Ecobee or Nest, can intuitively learn your habits, or explaining how properly sealed ductwork, checked with advanced diagnostic tools, stops precious cool air from playing hide-and-seek in your walls. It’s about using refrigerants with lower global warming potential, like R-32 where appropriate, and championing systems that not only regulate temperature but also improve air quality with things like HEPA filtration options. Our foundation is built on straightforward advice and a genuine desire to see you breathe a little easier, literally. We’re driven by the simple idea that a comfortable home is a happy home, and helping you achieve that, sustainably, is what gets us going every morning
