1. Inspect and replace your filter.
It's been sitting in place for months and getting worn out if you've been using central air conditioning. Replace your furnace's filter now (and every three or so months hereafter). Make sure you write down your filter's measurements before you leave the house.
2. Make sure it starts up.
On the first really cold day of winter, technicians are overwhelmed with service calls of heaters that won't turn on. Test yours out before then and you'll avoid the repair rush if there is a problem. Raise the thermostat setting to a point that's higher than the room temperature.After a minute or two your furnace should come to life.
3. Check the circuit breakers.
If your furnace doesn't come to, it's time to look for switches and circuit breakers. Check that both the switch on the furnace itself and on your home's circuit breaker are both powered on.
4. Get it professionally inspected.
If you're still having trouble, call a pro. Heating and cooling systems don't lend themselves well to amateur DIY repair. Call now and beat that cold snap rush. You'll sleep well (and warmly!) knowing that everything in your home is in tip top shape.
