Lower your energy bills and stay cozy all season long with smart, simple strategies and energy-efficient solutions from ARCO Heating & Cooling.


Winter in Missouri and Illinois can be beautiful—but it can also be brutal on your energy bill. Between longer heating cycles, drafty windows, and outdated equipment, many homeowners see their costs spike during the colder months. The good news? You can take control of your home’s energy use without sacrificing comfort.


In this guide, we’re sharing practical, proven tips to help you save money and improve efficiency—and how ARCO Heating & Cooling can support your winter energy goals.


Seal in the Heat with Proper Insulation

Heat loss is one of the biggest culprits behind high energy bills. Make sure your attic, crawlspace, and exterior walls are properly insulated. Don’t forget to check for drafts around doors and windows—weather stripping and caulking are affordable fixes that make a big difference.


Use a Programmable Thermostat

A programmable or smart thermostat lets you reduce heating when you’re asleep or away, saving energy automatically. Set it to a lower temperature during off-hours and warmer when you’re home for maximum efficiency.


ARCO Heating & Cooling installs energy-saving thermostats that are easy to use and designed to help you cut energy costs year-round.


Replace or Clean Furnace Filters

A dirty filter restricts airflow, making your system work harder to heat your home. Change or clean filters every 1–3 months to ensure optimal performance and lower energy usage.


Schedule a Professional HVAC Tune-Up

An annual inspection and tune-up can improve your system’s efficiency and catch small issues before they become big (and expensive) problems. ARCO Heating & Cooling’s seasonal maintenance services   are designed to optimize your system for peak performance during the coldest months.


Consider an Energy-Efficient Upgrade

If your furnace or HVAC system is more than 10–15 years old, it may be time to consider an upgrade. Modern high-efficiency systems use less energy and provide better comfort, which means lower bills and fewer headaches.


At ARCO, we offer top-rated, energy-efficient  HVAC installations with financing options and free consultations to help you find the right system for your home and budget.


Keep Vents Clear and Clean

Blocked or dirty vents prevent warm air from circulating properly. Make sure your vents are unobstructed by furniture, rugs, or curtains, and give them a quick vacuum every so often to remove dust buildup.


Embrace Natural Heat

Take advantage of free sunlight! Open your curtains during the day to let natural heat warm your space. Just remember to close them at night to trap the warmth inside.
