Frequently Asked Questions
Los Angeles residents typically save 40% to 70% on utility bills by switching to geothermal cooling. Because Southern California has high peak electricity rates during summer, the energy-efficient nature of ground-source heat pumps provides a faster return on investment compared to traditional AC units, especially when factoring in federal tax credits.
Yes, geothermal is highly practical for small Los Angeles lots through vertical loop installation. Rather than requiring vast land area, we drill narrow boreholes deep into the earth. This allows Custom Green Construction Inc. to implement powerful renewable energy systems even in densely populated neighborhoods with limited yard space available.
