How Heat Pumps Work in Cold Climates Like Lexington
Today’s air source heat pump technology handles Massachusetts winters with ease. Thanks to advances in cold-climate models, heat pumps can maintain high-efficiency operation even when outdoor temperatures dip below freezing.
Unlike traditional furnaces that burn fuel, heat pumps transfer heat from the outside air to warm your home. In warmer months, the process reverses, providing cooling.
Key Benefits for Lexington:
- Efficient performance down to -5°F or lower
- One system for both heating and cooling
- Significant reduction in greenhouse gas emissions
- No combustion risk inside the home
Local Performance Insights: Heat Pumps Work in Lexington
Given the architecture of many Lexington homes—ranging from classic Cape Cods to Colonial and newer builds—a ducted heat pump or zoning approach can meet the demands of multi-room layouts. At SumZero, we custom design every system to suit individual homes in town, using equipment certified for cold climates.
“In Middlesex County, homes with heat pumps saw significant energy savings after replacing older fossil fuel systems. The technology performs exceptionally well in our climate, especially with insulated homes.”
