On a cold night in Crystal Lake, its never a good thing when either there isn’t enough heat coming from your furnace, or there’s no heat, period. Most furnace repairs need the help of a qualified technician, but there are some things you can do to diagnose common heating problems before making a service call. Diagnosing Crystal Lake furnace problems is not that difficult. Here are some troubleshooting tips that you can try some may seem ridiculous, but you’d be surprised how many times we come out to a home only to find that a simple thing like a thermostat setting was the only reason a furnace was not working.

  • Look to make sure your thermostat is not on the cool or auto position, but the heat setting. Make sure you set the temperature a few degrees higher than room temperature, because if it isnt set in that position the heat will not come on.
  • Look for any sort of electrical problem. Find the power switch that is located on or near the furnace and make sure it is turned on. If the switch isnt located on the furnace, it will probably be located near the basement stairs. If that switch is on, you may have a tripped circuit breaker in the service panel box that usually hands on the wall where the electric meter is located. Move the breaker switch off before moving it back to the on position.
  • Hit the red safety button (it may be yellow on some models). On most heating systems, the electric motor has an overload reset button that pops out when the motor has overheated, and this shuts the furnace down. Make sure the motor has completely cooled and then press the red button back down again to manually restart the furnace. If the button does not reset within a minute, or if after the reset the furnace turns off, call a technician.
  • Make sure the furnace is getting fuel, and that the gas is turned on if you have a gas furnace. The gas valve should be turned to the open position. If your furnace uses liquid propane, make sure the tank is not empty. The tanks gauge appears like a round dial. The gauge for an oil furnace is typically on the top of the oil tank or at the side of the tank.
  • If you have a forced air heating system, replace the furnace filter. The heating efficiency of a furnace can be significantly reduced by a clogged or dirty filter. The filter should be cleaned every three weeks through the heating system and changed every three months. If you have a fiberglass filter, it should be changed monthly.

Again, the steps involved with diagnosing Crystal Lake furnace problems are fairly simple. Try all of them before you make a service appointment. If those steps do not work, though, please call Approved Comfort as soon as possible!
