Mini Split Installation & Repairs

Berkeley & San Francisco Bay Area Mini-Split Installation Near You

At 3rdGen Mini Split/Heat Pump Installation & HVAC Service, we are proud to provide top-notch products and services to our Bay Area community with our mini-split installation services. Mini-split heat pumps are a modern and efficient home heating and cooling option, offering unparalleled flexibility and energy savings. One of the standout features of these systems is their ability to provide zoning within your home. Each indoor unit that we install can be controlled separately, allowing you to customize the temperature in different areas of your home. This feature not only improves comfort in your home, but also leads to significant energy savings by heating or cooling only the rooms that you wish to.

Mini-split systems are versatile and suitable for various applications within the home. Whether you are looking to equip a whole home or a new construction with a state-of-the-art heating and cooling system, or you need an add-on for a house with a non-ducted heating system, mini-split installation is an excellent choice. They are also an ideal solution for room additions where extending or installing distribution ductwork is not an option. We also recommend mini-split installation for tiny homes or where energy-efficiency is a top priority for our clients.

Leading the way

Let’s build a more efficient world together with fully electric heating and cooling solutions

California’s aim is to reduce greenhouse gas emissions and to combat climate change. Gas powered appliances create combustion which produces air pollutants that harm air quality and human health and contribute to emissions that are also harmful to the Ozone layer.

Highly Energy-Efficient

Heat Pumps require less energy input than gas furnaces to provide heating and cooling

Versatility

Heat pumps can provide both heating and cooling, eliminating the need for a separate system

Long-Term Cost Savings

Despite higher upfront costs, heat pumps offer long-term energy savings, offsetting the initial investment

Environmental Friendliness

Heat Pumps do not burn fuel on-site and thus produce fewer greenhouse gas emissions

Safety

Since Heat Pumps do not burn fuel, carbon monoxide and explosion concerns are non-existent

Government Tax Credits & Rebates

These are federal incentives as well as state, county, and city programs, that reward homeowners who purchase and install energy efficient technologies, such as heat pumps

The Future of Heating & Cooling in America is all electric

We’re at the forefront of HVAC Technology in the San Francisco Bay Area and are keeping an active open dialogue with our suppliers and equipment manufacturers to meet our clients needs in the most efficient way possibly while helping California reach their energy goals; No matter what the case is, we have a solution to meet comfort needs.
