When energy bills arrive each season, many Illinois homeowners wonder the same thing: Is heating or cooling more expensive? It’s a fair question. After all, both systems are essential for year-round comfort in the Midwest. At Comfort First Heating and Cooling, we’ve helped countless families across Illinois manage their HVAC systems efficiently and cost-effectively. Let’s explore why that’s the case, what drives HVAC costs, and how you can keep your bills under control all year long.
Understanding What Drives HVAC Costs
The cost to heat or cool a home isn’t just about outdoor temperatures; it depends on a mix of factors that influence energy efficiency and system performance.
Energy Source
Different fuels have different costs. In Illinois, many homes rely on natural gas furnaces, though some use propane or electric heat. Natural gas is generally more affordable than electricity per BTU of heat, but winter demand spikes can cause gas prices to rise. Air conditioners, by contrast, run on electricity, which can be costly during peak summer months depending on your utility provider.
System Efficiency
Heating and cooling efficiency ratings play a big role in overall operating costs. AFUE (Annual Fuel Utilization Efficiency) is used for furnaces and SEER (Seasonal Energy Efficiency Ratio) for air conditioners. Older systems or those with lower ratings require more energy to produce the same level of comfort.
Home Insulation and Air Sealing
A poorly insulated home leaks conditioned air, forcing your furnace or air conditioner to work harder. Proper insulation, weatherstripping, and air sealing keep warm air in during winter and cool air in during summer, reducing HVAC run times.
Climate
Illinois experiences long, cold winters and warm, humid summers, meaning your HVAC system has to handle both extremes. Because heating season lasts longer than cooling season, it typically consumes more total energy over the year.
Thermostat Habits and Maintenance
Even small habits, like lowering your thermostat a few degrees at night or scheduling routine maintenance, can make a big difference. Clean filters, well-tuned components, and smart thermostats help both heating and cooling systems run more efficiently and use less energy overall.
Heating Costs in Illinois
In Illinois, heating systems are a necessity for survival through months of snow, wind, and subfreezing temperatures. Most homes rely on gas furnaces, though some still use electric furnaces, boilers, or heat pumps.
Heating generally costs more because:
- Winters are long and harsh. Furnaces often run for hours at a time to maintain indoor comfort.
- Temperatures dip below freezing, sometimes for weeks, demanding more energy to heat incoming air.
- Natural gas prices fluctuate in the winter due to regional demand.
If your furnace is aging or your home lacks proper insulation, heating costs can soar even higher. Older systems with AFUE ratings below 80% waste energy, meaning a large portion of the fuel you pay for never becomes usable heat. Upgrading to a high-efficiency furnace (95% AFUE or higher) can dramatically lower your utility bills.
Cooling Costs in Illinois
While cooling costs are generally lower than heating costs overall, electricity use during July and August can still make bills climb. Cooling costs depend on several key factors:
- Electricity rates: Utilities often charge more during summer peak demand hours.
- System efficiency: Modern AC units with SEER2 ratings of 16 or higher use far less electricity than older models.
- Home insulation: Good insulation and shade help reduce AC run time.
- Thermostat habits: Every degree lower on your thermostat increases energy use by about 3–5%.
High-efficiency air conditioners and smart thermostats can significantly reduce your cooling costs without sacrificing comfort. Keeping filters clean, sealing ducts, and ensuring proper refrigerant levels also go a long way toward minimizing wasted energy.
Heating vs. Cooling: A Cost Comparison
Here’s a simplified look at how heating and cooling stack up for most Illinois households:
|
Factor |
Heating |
Cooling |
|
Duration of use |
5–6 months (long, cold winters) |
3–4 months (warm, humid summers) |
|
Energy source |
Natural gas, propane, or electricity |
Electricity |
|
Efficiency rating |
AFUE (often 80–95%) |
SEER (often 13–20+) |
|
Typical utility bills |
Higher winter gas bills |
Moderate summer electric bills |
|
Climate impact |
Extreme cold increases run time |
Shorter season but higher humidity |
For most Illinois homeowners, heating remains the higher annual expense, simply because it’s needed for a longer period and must work harder to overcome extreme cold. However, inefficient or poorly maintained cooling systems can still rack up significant costs, especially in humid areas or older homes.
What Factors Can Tip the Balance?
While heating usually dominates utility spending, several factors can shift the balance:
- Old or inefficient systems that waste energy.
- Poor insulation or drafty construction that leaks air.
- Utility rate changes that spike costs during peak demand.
- Thermostat habits, like keeping temperatures too high or low year-round.
- Lack of regular maintenance, which reduces efficiency and shortens system lifespan.
A home energy assessment can help identify the biggest culprits and reveal where upgrades or adjustments could deliver the biggest savings.
