Adjust Your Thermostat Settings for Cooler Weather

Adopting better thermostat habits today can lead to more efficient temperature regulation come fall and winter. Now is the time to switch your thermostat from cooling to heating mode and fine-tune your settings for the challenges ahead. Minor adjustments can help you stay cozy while controlling your energy costs.

Aim to keep your home at 70 degrees or lower when you’re home and drop it to around 62 degrees when you’re away or sleeping. A new thermostat can automate these changes and even optimize settings based on your routine.

Once you’ve programmed a schedule that works for your household, resist the urge to override it. Try layering on a sweater if you feel chilly. When you absolutely need to adjust the temperature, increase it gradually – cranking the heat won’t warm your home faster, but it will use more energy.

Check Your Ductwork and Furnace Flue

It’s smart to inspect your home’s heating infrastructure before cooler weather settles in, starting with your ductwork. Leaky or poorly sealed ducts are hidden energy vampires that can also compromise your indoor air quality. A quick inspection could reveal gaps, loose connections or buildup that may affect your airflow. If you notice excessive dust or debris, schedule your duct cleaning in O’Fallon to improve system performance and reduce your utility bills.

While you’re checking your heating equipment, don’t forget to examine your furnace flue. This critical component vents combustion gases safely out of your home. A blocked or damaged flue can pose serious safety risks, so keep it clear and functioning properly. Call Home Heating & Cooling for expert furnace repair in O’Fallon if anything seems off. We’ll get it working safely and efficiently for you.

Inspect Your Smoke and CO Detectors for Safety

Don’t forget a potentially lifesaving step in preparing your home for cooler weather: checking your smoke alarms and carbon monoxide detectors. These devices are your first line of defense against hidden dangers, especially as you start using your heat daily.

Carbon monoxide is a colorless, odorless gas that can leak from malfunctioning furnaces or other fuel-burning appliances. Without a working detector, you may not know you have a problem until you or someone in your family gets sick. As the best HVAC company in O’Fallon, we recommend testing and replacing your detectors’ batteries when you “fall back” with your clocks in November.

You should have detectors installed near bedrooms and on every level of your home. It’s time to replace these devices if they are more than 10 years old. A quick check now can give you peace of mind all season.

Clear and Maintain the Area Around Your Furnace

Your furnace needs a clean, unobstructed space to keep you warm this winter. While you work through your fall HVAC maintenance checklist, take a few minutes to clear clutter, dust or debris from the area around your furnace. Items stored too close to the unit can restrict airflow, pose fire risks and make it harder for our technicians to perform routine service.

Now is also the ideal time to visually inspect your furnace for signs of wear or aging. You may need to consider furnace replacement and installation if your system is more than 15 years old, struggles to keep up with your demands or requires frequent repairs. Home Heating & Cooling’s trained techs will explain your options and help you find an affordable, energy-efficient solution that fits your home and budget.
