Cooling Or Heating: Which One Costs More To Run?

In colder climates, heating systems cost more per hour to operate, while cooling systems tend to generate higher annual expenses in warm climates. For homeowners comparing cooling or heating, the total cost depends on climate, fuel type, system efficiency, and daily runtime. In this guide, Southern HVAC will evaluate each factor to recommend the most cost-effective option for long-term comfort.
Key Takeaways
- Heating costs more per hour than cooling due to higher energy demand.
- Cooling or heating costs depend on climate, runtime, and system efficiency.
- Heating uses about 42% of residential energy, while cooling uses around 17%.
- Air conditioners consume less electricity per hour but run longer in warm regions.
- Proper HVAC sizing and high-efficiency systems reduce long-term energy costs.
Is Heating Or Air Conditioning More Expensive On Energy Bills?
Which system uses more energy per hour, an air conditioner or a heater? When comparing cooling or heating, heating systems are more expensive per hour than air conditioners because heaters generate heat instead of moving heat. Most heaters rely on gas, oil, or high-wattage electric resistance heating, which increases energy demand during operation.
According to the
U.S. Energy Information Administration, heating accounts for about 42% of average residential energy use nationwide, while cooling accounts for around 17%, with regional variation based on climate. Modern
heaters and AC systems with high efficiency ratings reduce monthly bills compared to older equipment.
Why Heating Systems Usually Consume More Energy
Does it take more energy to heat or cool? Heating requires more energy than cooling because raising indoor air temperature above outdoor levels demands higher BTU output and longer operating cycles. Gas furnaces typically operate between 80 and 98% AFUE efficiency, while electric resistance heaters convert electricity fully but cost more per kilowatt hour.
Higher
heater energy usage also results from heat loss through walls, ceilings, and ductwork. Poor insulation in walls, attics, and duct systems
can increase heating demand by up to
30%, raising overall energy costs.
Does Cooling Cost More Than Heating In Southern States?
Cooling costs more annually than heating in southern states because air conditioning runs for longer periods each year. Rising temperatures increase air conditioning energy consumption across southern states. Louisiana homes often rely on air conditioning for eight to ten months, which increases total electricity consumption.
Improper system sizing raises cooling costs by
15 to 25% by causing short cycling and airflow imbalance.
Proper AC sizing improves airflow balance and efficiency, while planning for future
AC replacement cost helps control long-term expenses.
Why Air Conditioning Use Keeps Increasing Every Year
Air conditioning demand continues to increase due to higher average temperatures and population growth in warmer regions. The National Oceanic and Atmospheric Administration reports steady increases in summer heat across the southern United States.
Urban development raises indoor heat retention, while modern lifestyles expect stable indoor comfort. New systems improve airflow efficiency through variable speed compressors, reducing energy spikes and stabilizing monthly bills.
How To Reduce Heating And Cooling Costs Year-Round
Homeowners can reduce heating and cooling costs year-round by lowering runtime, improving system efficiency, and reducing heat loss and gain through consistent habits and proper system setup.
- Set thermostats to 68°F for heating and 78°F for cooling to reduce unnecessary energy use.
- Schedule routine HVAC maintenance to maintain system efficiency and prevent unexpected performance loss.
- Seal duct leaks to reduce energy loss by up to 20% and improve airflow consistency.
- Replace dirty air filters every 1 to 3 months to maintain steady airflow and lower system strain.
- Upgrade insulation in attics and walls to reduce heat transfer during extreme temperatures.
- Use programmable or smart thermostats to limit heating and cooling during unoccupied hours.
- Work with a professional HVAC service to ensure correct system sizing, airflow balance, and equipment efficiency.

High energy bills often come from inefficient HVAC systems or improper sizing rather than energy prices alone. Upgrading the right system reduces operating costs and improves long-term comfort.
Southern HVAC evaluates home size, insulation, ductwork, and airflow to recommend efficient solutions. Schedule heating system installation in Hammond with Southern HVAC - trusted local professionals for lower utility bills and reliable comfort.
FAQs
Which uses more electricity air conditioner or the heater?
Electric heaters use more electricity per hour than air conditioners because heaters generate heat directly instead of transferring heat.
Does AC cost more than heat in warm climates?
Air conditioning costs more annually in warm climates due to longer seasonal usage.
Does heating or cooling cost more overall?
Heating costs more per hour, while cooling costs more per year in southern regions.
Is it cheaper to heat with gas or electricity?
Gas heating is usually cheaper than electric heating in most U.S. regions.
Does a space heater use more electricity than central heat?
Space heaters consume more electricity per square foot than central heating systems.
