It’s not uncommon for L & J Heating & Cooling to hear from customers who are experiencing a surprising issue: heaters blowing cold air. This is a very unwelcome surprise, since your heater is supposed to be keeping you warm! If you’re having this issue as well, give us a call for quick heating system repair in Oregon City, OR. In the meantime, here are a few tips for decoding your furnace’s cold air problem:

  • Give it some time: Sometimes the solution is obvious and easy, and that’s the best kind! Here’s one solution that’s worth a shot: turn your heater on and wait a few minutes. Many people don’t realize that heaters and air conditioners need to get going before they start to regulate the temperature. So, your heater might simply be warming up. If it’s still not blowing hot air after a few minutes, you probably need to call a heating contractor in Oregon City, OR to help you out.
  • Check the thermostat: It seems intuitive that your thermostat should be set to “on” in order for the heating to work. But in reality, “on” simply means that the furnace will continuously blow air, even when it isn’t heating it. Luckily, the fix is easy: change the setting to “auto.” Now, your furnace will kick on only when the home falls below temperature, and thus will only blow heated air.
  • Turn it up: Sometimes setting the thermostat a little higher makes all the difference for your furnace. Make sure yours is set to a slightly warmer temperature than the current temperature in the house. If you don’t do this, the furnace won’t kick on, because it won’t think the house is in need of additional heating.
  • Look at the pilot light: Your furnace has a pilot light, and it will only blow warm air as long as the light is lit. Check your furnace to see if the light is on. If it isn’t, try to relight it. If you can’t relight it, check to see that gas is flowing correctly into your unit. In order for this to happen, the switch for the gas valve must be set to “on.” If you can light the gas but it won’t stay on, you may have an additional issue that needs to be addressed by a professional heating contractor in Oregon City, OR.
  • Get it inspected: One of the easiest ways to figure out why your furnace is blowing cold air—and keep that from happening again down the road—is simply to have it inspected regularly by a professional heating contractor. L & J Heating & Cooling is your local expert in furnace maintenance, installation and heating requirements, so don’t hesitate to give us a call for any maintenance or inspection needs you may have.
