As cold weather hits Hampton Roads, many homeowners are turning up the heat to stay warm, but experts warn that blasting the thermostat could send energy bills soaring if homes aren't properly winterized. HVAC expert Art Mowry says disconnected ductwork and aging insulation are common issues that can lead to major heat loss and higher utility bills, especially when homeowners crank up the heat to 75 degrees or higher.

Why it matters

Proper home insulation and ductwork maintenance are crucial for keeping energy costs down during the winter months, but many homeowners overlook these issues until it's too late. Addressing these problems can save hundreds of dollars on heating bills over time.

The details

Mowry, who has over 25 years of experience inspecting homes, says he has seen ductwork completely disconnected, causing heat to pour out underneath houses. He has also responded to many homes with insulation that hasn't been updated in years. These problems can put serious strain on heating systems, especially electric systems that rely on heat strips for supplemental or emergency heat, which use significantly more electricity.
