Let’s build a more efficient world together

California is switching from natural gas to electric power

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.

Heat Pumps are the ideal modern solutions for heating and cooling and here’s why:

Highly Energy-Efficient

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


Heat Pumps can provide both heating and cooling, eliminating the need for separate system.

Long-Term Cost Savings

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

Environmental Friendliness

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


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 home owners who purchase and install energy efficient technologies, such as heat pumps.
