As summer heat fades and temperatures start to drop, your HVAC system is about to switch gears — from cooling your home to keeping it warm. A little attention now can save you from a mid-winter breakdown and help your system run more efficiently all season long. Here are seven simple things every homeowner should do before the cold weather sets in.
1. Replace or Clean Your Air Filter
A clogged filter forces your system to work harder, driving up energy bills and shortening the life of your equipment. Check your filter monthly, and replace it right away if it looks dirty. This is the single easiest maintenance task you can do yourself, and it makes a real difference.
2. Test Your Thermostat
Before you need heat every day, run a quick test. Switch the system to “heat” and make sure it responds properly and holds a steady temperature. If you’re still using a manual thermostat, fall is a great time to consider upgrading to a programmable or smart thermostat — it can shave real money off your winter heating costs.
3. Clear Debris Around Outdoor Units
Leaves, grass clippings, and yard debris can build up around your outdoor unit over the summer. Clear at least two feet of space around it so air can flow freely and the system doesn’t have to strain.
4. Check and Seal Ductwork
Leaky ducts let heated air escape before it ever reaches your rooms, which means your system runs longer to hit the same temperature. Look for any visible gaps, tears, or disconnected sections, and seal them with mastic sealant or metal tape.
5. Inspect Weatherstripping and Insulation
Your HVAC system isn’t working alone — your home’s insulation and seals play a big role in keeping conditioned air where it belongs. Check weatherstripping around doors and windows, and top up attic insulation if it’s looking thin. This takes pressure off your furnace and keeps rooms more evenly heated.
6. Schedule a Professional Tune-Up
DIY checks catch the obvious stuff, but a professional inspection catches the problems you can’t see — worn components, refrigerant issues, electrical connections, and safety concerns like carbon monoxide leaks. An annual fall tune-up is the best insurance policy against a furnace failing on the coldest night of the year.
7. Test Your Carbon Monoxide and Smoke Detectors
As furnaces and heating systems fire up for the first time in months, this is the perfect moment to test detectors and replace batteries. It’s a five-minute task that protects your whole household.
Don’t Wait for the Cold Snap
Most HVAC emergencies happen at the worst possible time — the first genuinely cold week of the year, when every other homeowner is calling for service too. Getting ahead of it now means shorter wait times, lower risk of surprise breakdowns, and a more efficient system all winter.
