Know The Signs That Indicate Your Furnace Is Not Working Properly

If a furnace is struggling to keep a home warm or is not working at all, it is time to check for warning signs. Generally, a furnace that is having issues will offer signs that indicate problems. Many of these signs are noticed during an annual Furnace Inspection; however, some signs are not present during inspections.

Two of the most common Furnace Warning Signs are unusual noises and gas odors. If a furnace is making strange noises, or when the smell of gas is present, it is time to contact an HVAC contractor. These two signs are indicators of a furnace that may need to be repaired.

If you smell gas or hear strange noises, it is important to get help immediately. Putting these signs off can cause further damages, and it puts household members in danger. Another serious warning sign that should never be ignored is a yellow or orange flame. A furnace flame should always burn blue; it should also be stable and appear clean.

When flames are yellow or orange it is a sign of dirt build up in the burner, or other possible issues. An unstable flickering yellow or orange flame is an indication that the furnace is not producing an appropriate mixture of gas and oxygen. Ignoring this sign can lead to a large gas leak and lead to disaster. If a yellow or orange flame is noticed the furnace should be shut down until a professional can inspect it.

A faulty or broken thermostat will also give homeowners warning signs. When a thermostat is broken or not working properly, the furnace may cycle on and off quite often, or not operate for as long as it should. A home that does not seem to get warm regardless of the temperature setting is another sign of a broken thermostat.

Obstructed airflow in front of vents is another reason a furnace will struggle to keep a home warm. Dirty air filters should be changed or cleaned often because dirty filters make furnaces work extra hard. Play it safe and contact your local HVAC contractor as soon as you notice signs that you are unable to solve.
