Vermont, historically resistant to widespread air conditioning use, is experiencing a shift as climate change leads to hotter and more humid summers. The state has one of the lowest rates of AC ownership in the U.S., with only about two-thirds of homes having any form of cooling and a mere 7% equipped with central air.
Recent data from the National Weather Service indicates a significant increase in days exceeding 80 and 85 degrees Fahrenheit in Burlington compared to the mid-20th century. Furthermore, rising humidity levels are contributing to higher heat index values, making days feel considerably hotter and nights warmer. This trend is prompting more Vermonters to seek cooling solutions.
Local HVAC business owners report a surge in demand for heat pumps, devices that offer both heating and cooling, with customers prioritizing cooling functions. However, the high cost of these units and their installation presents a significant barrier for many residents. Experts emphasize that affordability of cooling, energy provider capacity to meet increased demand, and proper funding for energy assistance programs are critical considerations.
The issue extends beyond individual homes, with many schools nationwide lacking adequate HVAC systems, impacting student learning. While some communities are developing heat action plans, effective implementation and funding are essential. Health officials advise staying hydrated, avoiding strenuous outdoor activity during peak heat, and creating cool spaces within homes, such as bedrooms, to cope with extreme temperatures.
