With utility bills rising across the United States, many homeowners are looking for ways to reduce their energy usage. One Bay Area homeowner took to Reddit to share how upgrading from a gas furnace to a modern heat pump slashed their winter utility bills. 

The user noted that their new unit was, on average, 20% cheaper than their gas furnace, despite living in California's more expensive electricity market. 

One of the most effective ways to do so is by upgrading to a highly efficient heat pump. The original poster proved this point by comparing winter energy bills after upgrading from a decades-old AC unit and gas furnace to a Gree Flexx Ultra heat pump.

They found that in February 2026 compared to the same month in 2025, their HVAC system was 15% cheaper to run. In a similar comparison with January figures, their new system was over 25% cheaper. 

Those savings can quickly add up, especially in areas of the U.S. where electricity costs are more expensive, such as California. "Heat pumps absolutely can make sense in California, depending on your electricity and gas rates," the homeowner said.

Electric heat pumps can also reduce a home's pollution output by avoiding burning gas to power a traditional furnace, making neighborhood air a little cleaner. 

"Great story, thanks for sharing!" one commenter said. "And... we humbly agree."

"It's great that you are seeing savings," added another.
