Have you opened your latest electric bill and done a double-take at the total? You’re not the only one. Homeowners across North Carolina are seeing their energy costs spike — and most often, the culprit isn’t new gadgets or appliances. It’s your HVAC system working harder than it should. As we explain in our video, that surge in electricity use may be a warning sign you don’t want to ignore.
At Blue Collar Trades, we help homeowners across Rockwell, Concord, Kannapolis, Harrisburg, Landis, Davidson, Cornelius, Mooresville, and nearby areas find out what’s causing their bills to climb — then get things under control. Here’s what to watch for, and how you can save.
When filters are dirty or clogged, airflow is restricted. That forces your HVAC system to run longer or work harder to deliver the same heating or cooling — which dramatically increases energy usage.
What to do: Replace or clean filters every 1–3 months (more often if pets, dust, or pollen are factors).
If your HVAC unit is old, worn-out, or simply inefficient, it may draw much more power to try and heat or cool your home. According to energy-efficiency guidance, older systems frequently consume more electricity to deliver the same comfort.
What to do: Consider scheduling an inspection — if major components are failing, you may save more long-term by upgrading to a newer, high-efficiency unit.
Leaks in ducts or refrigerant lines cause your system to lose efficiency fast. Escaping air or improperly cooled air forces the system to run extra cycles, pushing up power consumption.
What to do: Have a professional check ductwork and refrigerant levels — sealing leaks or repairing refrigerant loss can restore efficiency and slash bills.
Like any major home appliance, HVAC systems need routine maintenance. Without it, components degrade over time, performance drops, and power usage rises. Routine maintenance ensures coils are clean, airflow is smooth, and all parts operate properly.
What to do: Schedule a seasonal tune-up. Annual or biannual service can keep your system running efficiently, lengthen its lifespan, and lower energy bills.
In North Carolina, summer heat and winter cold mean heavy reliance on HVAC. Cooling and heating account for nearly half of a home’s energy use.
What to do: Combine sensible thermostat settings with proper maintenance to avoid skyrocketing bills when the weather gets extreme.
