Step 1. A quick thing to do is to check the thermostat. Is it set on and set on the “heat” setting?

Step 2. Another quick check is your furnace switch. Make sure it’s at the “on” position.

Step 3. Check the circuit breaker. Is it possible the breaker to your furnace tripped?

Step 4. Check the furnace filter. It’s easy to overlook a clogged filter. Be sure to change it out if it’s dirty.

Step 5. Is the front panel of your furnace closed properly?

Step 6. What about the gas valve? Did you make sure it is at the “on” position?

Step 7. Don’t forget to check the air ducts. Have them become blocked?

Step 8. Call a professional if you’re still having problems.

What’s the climate like? It can be complicated to factor it all in, but a well-trained HVAC contractor can use a Manual J to help you find the right answer for your home.

Installation and maintenance play an important role in the lifespan of your unit. A well-maintained air conditioning system should last you about 12-15 years, while a heat pump should see about 14 years. When it comes to aging units, once your system is over 10 years old, you may want to consider replacing it over repairing it, so you have a more efficient unit.
