High energy bills and environmental concerns have brought a great deal of focus to the topic of high efficiency heating equipment. Hassler is a full service furnace installation company servicing El Cerrito, San Ramon, Walnut Creek, Berkeley, Mill Valley, and surrounding areas. Our technicians are trained and prepared to handle your furnace installation needs. At Hassler, we know it's important to get the right furnace for your home to keep you and your family warm during the colder months.

heat pumps el cerrito

Hassler provides installation, repair and maintenance services for heat pumps which is a cost-effective way of heating your home in winter months. Heat pumps typically have a higher efficiency rating than “gas fired” furnaces and have the added benefit of providing cooling in the summer. Heat pumps are perfectly suited for the East Bay Area’s moderate climate. They offer an energy-efficient alternative to furnaces and air conditioners.

wall heaters

Designed to heat a specific zone or multiple rooms, a natural vent or direct-vent wall furnace is a smart, energy-saving solution to inefficient, electric baseboard or traditional heating systems.

Hassler provides new installation, repair, replacement and maintenance services for both natural vent wall heaters and direct vent heaters. Both types of heaters are an ecomonical way to heat a small home or an individual space.  A direct vent heater is ideal in cases where it’s difficult to vent out the roof (they can vent directly out the side wall adjacent to the heater).

mini split heat pump

Ductless mini splits are gaining a reputation as the next big thing in heating and cooling technology. Homeowners in Orinda, Oakland, Ross, and surrounding areas are beginning to see mini split heat pumps as a solution to home heating and cooling. Operating without having to rely on a central ductwork system, mini splits provide whole home comfort in ways that traditional heating and cooling systems cannot. They can be utilized in rooms where ductwork is not accessible, but also as a supplement to your main heating and cooling system.

With excessively hot temperatures during the summer months, having an air conditioning system that is reliable and efficient is a top priority.

Heating a home's water is among the top household energy burdens, second only to heating and air conditioning.

smart thermostat el cerrito

Hassler provides installation, repair, and maintenance services for programmable thermostats, which are energy efficient and are ideal for people who are away from home during set periods throughout the week.

zoned air systems

Take a moment to think about how the lighting in your home works. Imagine if you had one master lighting switch that controlled the whole home with a single flip. You might only need the light of a small lamp, but every light in the house would come on at once. It wouldn’t make sense, right? The amount of energy that would get lost in this process would be nothing short of overwhelming, which is exactly why you shouldn’t be controlling home heating and cooling in such a way.

They took out our wall furnaces and installed an energy efficient 2 zone heating system. Mike explained his whole process step by step and provided me with many options. I was very pleased with the work they did and would recommend them to anyone.
