As the weather cools down, many homeowners wonder when to turn the heating on and how to prepare their system for the season. Turning on the heater for the first time before winter isn’t just about flipping a switch; it’s about making sure your furnace is ready to provide safe, efficient comfort.
At Modern Air Solutions, we’ve put together a comprehensive checklist of what to do before turning the heat on for the first time this year. Following these steps will help keep your system running smoothly, improve air quality, and prevent costly repairs.
1. Inspect the Furnace
If you’ve kept up with regular maintenance, your inspection should be quick. Still, it’s important to:
- Look for soot, dust, or oil residue inside the unit.
- Inspect the blower belt for cracks or heavy wear.
If anything looks damaged or you notice odd residue, avoid turning the heat on and call for professional service. Our experienced HVAC contractors at Modern Air Solutions will be happy to help ensure your heating system is in top shape before winter.
2. Replace the Air Filter
When turning on the heat for the first time, always start with a fresh filter. Standard air filters should be replaced every 1-3 months. However, the exact replacement interval depends on the filter thickness, household conditions, and usage patterns. Check your filter before turning on the heat and always replace it if it looks dirty or clogged.
Installing the correct size filter also ensures your furnace runs efficiently and improves indoor air quality. If you’re not sure which filter to buy, one of our technicians can provide recommendations.
3. Clean the Vents and Registers
Before switching on your heating system:
- Clean dust and debris from all vents and registers.
- Check that furniture isn’t blocking airflow and leave at least one foot of clearance. (This also helps reduce the likelihood of your furniture being damaged by heat.)
Blocked vents make your furnace work harder and can reduce both comfort and efficiency.
4. Have Your Air Ducts Cleaned
Air ducts should be professionally cleaned every 3 to 5 years. Dust, pollen, and even mold can build up in hidden areas. Turning on your furnace for the first time with dirty ducts can spread pollutants throughout your home. Professional duct cleaning removes buildup and helps your system better deliver clean, conditioned air.
5. Check the Thermostat
Your thermostat is the control center of your heating system. Set it to your desired temperature and make sure it responds correctly. If you’ve been considering an upgrade, fall is a great time to install a smart thermostat for improved comfort and energy savings.
6. Test Smoke and Carbon Monoxide Detectors
Safety must be a priority when turning on the heat for the first time this winter. Test your smoke detectors and carbon monoxide detectors, and replace batteries if needed.
Because furnaces burn fuel, carbon monoxide leaks are a serious risk if the system isn’t working properly. Additionally, hidden electrical issues or HVAC issues could pose a fire hazard. Detectors can give you an early warning and peace of mind.
7. Inspect Outdoor Vents
Walk around the outside of your home and check the furnace intake and exhaust vents. Remove any leaves, dirt, or debris blocking airflow. Clear vents allow your heating system to safely release gases and operate without restriction.
8. Schedule a Professional Tune-Up
While you can handle basic checks on your own, scheduling professional furnace maintenance before winter is one of the best ways to prevent breakdowns. During a tune-up, our licensed HVAC specialists at Modern Air Solutions will:
- Inspect and clean internal components
- Check for gas leaks and ensure safe operation
- Lubricate moving parts
- Test system efficiency and airflow
- Check your thermostat
A fall tune-up helps your furnace last longer, saves energy, and reduces the chance of mid-winter repairs. Learn about our HVAC maintenance agreements for great warranties, deals on repairs, and other perks!
