Why Your Summer Energy Bill Keeps Climbing, According to HVAC Experts
Chapin, S.C. – September 18, 2026 -- A high summer energy bill rarely comes from one single problem, according to HVAC experts Rick Liberti and Jon McCartha of Mid-State Heating and Air LLC in Chapin, South Carolina. Their insights, featured in a new HelloNation article, break down the everyday household issues that push cooling costs higher during peak heat.
Dirty filters force HVAC systems to work overtime
Dirty filters restrict airflow, making the system use more energy just to circulate air through the home. Beyond raising costs, this strain also reduces overall indoor comfort.
Poor insulation lets cooled air escape through walls and gaps
When cool air leaks out through attics, walls, or gaps around doors and windows, the HVAC unit has to work harder to replace it. Even a properly functioning system can struggle to keep temperatures steady in a poorly insulated home.
