5 Smart Ways to Prepare Your Heating System for Winter in New England

5 Smart Ways to Prepare Your Heating System for Winter in New England

October 27, 2025

When cold weather hits New England, your heating system becomes the unsung hero of your home. Before temperatures dip below freezing, take a few simple steps to make sure your system is running safely, efficiently, and ready to keep your family warm.

1. Schedule a Professional Tune-Up

An annual heating system tune-up is one of the best investments you can make before winter. A certified technician will inspect your furnace, boiler, or propane system, clean key components, and make sure everything is operating safely. Regular maintenance helps improve efficiency, extends the life of your equipment, and can even lower your energy costs.

2. Replace or Clean Air Filters

Air filters collect dust and debris that can restrict airflow. If your heating system has to work harder to push air through a dirty filter, it uses more energy and may wear out faster. Check your filters monthly and replace or clean them at least once every three months—more often if you have pets or allergies.

3. Seal Air Leaks and Add Insulation

Drafts around windows, doors, or attic spaces can make your system work overtime. Check for gaps where warm air can escape and seal them with weatherstripping or caulking. Adding insulation in key areas like your attic or basement can make a big difference in comfort and energy savings.

4. Test Your Thermostat

Before the first big chill, turn your system on to make sure the thermostat responds correctly. If your home isn’t reaching the set temperature, it could be time for a new thermostat or system check. Upgrading to a programmable or smart thermostat helps you automatically adjust temperatures and save energy when you’re away.

5. Check Your Propane or Heating Oil Supply

Don’t wait until the first snowstorm to discover you’re low on fuel. Check your tank level and make sure you’re enrolled in Automatic Delivery or have a remote tank monitor for peace of mind all winter long. Proulx Oil & Propane customers can also manage deliveries, payments, and service requests easily through our mobile app.


Bonus Tip: Think Ahead for Safety

Make sure your carbon monoxide detectors have fresh batteries and are placed near sleeping areas. A quick check today can help protect your family all season long.
