Winter is coming.

Your furnace shouldn’t be a surprise.
Prepare now. Stay warm later.

5 Ways to Prepare Your HVAC System

1. Schedule Furnace Maintenance

Have your furnace inspected and serviced before the heating season begins. Regular maintenance can help identify potential problems before they become an unexpected winter breakdown.

2. Replace Your HVAC Filter

A dirty filter can restrict airflow and make your furnace work harder. Check your filter regularly and replace it when needed with the correct size and type for your system.

3. Check Your Vents & Registers

Make sure supply and return vents are not blocked by furniture, rugs, curtains, or other items. Proper airflow is important for even heating throughout your home.

4. Keep Your Outdoor Unit Clear

If you have a heat pump, keep the outdoor unit clear of leaves, grass, snow, and other debris. Make sure there is enough space around the unit for proper airflow, and never block the outdoor coil or fan.

5. Don’t Ignore Warning Signs

Unusual noises, weak airflow, frequent cycling, uneven heating, or a furnace that struggles to maintain temperature can indicate a problem. Getting it checked early may help prevent a larger breakdown during extreme cold.

🚨 Don’t Wait Until the First Cold Night

If your furnace hasn’t been maintained or you’re noticing a problem, now is the time to have it checked.
