Hassler offers services in retrofitting older homes with new and more energy efficient heating and cooling systems, and has extensive professional knowledge about the Bay Area’s specific heating requirements.

Homeowners in El Cerrito, Berkeley, San Rafael, and the surrounding area know how important home comfort is, and our team at Hassler has the experience and equipment to make sure your air conditioning system is installed correctly and effectively.

Except for heating and air conditioning, our homes use more energy for water heating than any other task! 25% or more of your home’s energy consumption typically goes to water heating, and the model you choose can have a big impact on consumption.
