In this post, we\u2019ll go over some of the troubleshooting steps to follow when your furnace isn\u2019t heating your house.&nbsp;<a href=\"https:\/\/www.shaferhvac.us\/blog\/heating-service\/why-wont-furnace-evenly-heat-house\/\">Learn why your furnace might not be heating evenly<\/a> and other potential issues to address.<\/p>\n\n\n\n<!--more-->\n\n\n\n<p>Important note: These aren\u2019t <em>repair<\/em> steps\u2014you shouldn\u2019t attempt to open your furnace and use tools to fix it on your own! It\u2019s potentially dangerous. Once you\u2019ve gone through these steps, it\u2019s time to call us for the professional assistance you need.<\/p>\n\n\n\n<h3><strong>Check the furnace switch<\/strong><\/h3>\n\n\n\n<p>The furnace has a dedicated breaker switch located near the cabinet which is used to shut down the unit during the off-season so it can be serviced. If this is the start of the season, you may have forgotten to turn the switch back on.<\/p>\n\n\n\n<h3><strong>Check the electrical panel<\/strong><\/h3>\n\n\n\n<p>One of the most common reasons for a non-responsive furnace is a tripped circuit breaker. Yes, this applies to gas furnaces as well, as modern gas furnaces have numerous electrical components and use an electrically powered blower fan. Reset a tripped breaker and try the furnace again. If the furnace continues to trip the breaker, call for repairs.<\/p>\n\n\n\n<p>If the breaker repeatedly trips even after resetting, it could indicate a deeper electrical issue such as a short circuit or overloaded wiring in the furnace. Avoid resetting the breaker multiple times, as this could damage the system further or create a fire hazard. Instead, contact a professional technician for a thorough inspection.<\/p>\n\n\n\n<h3><strong>Check the thermostat<\/strong><\/h3>\n\n\n\n<p>Often, a mistake with thermostat settings can account for a furnace failing to turn on when needed or only running for a short time. Make sure the thermostat is set to \u201cheat\u201d (often \u201cauto\u201d won\u2019t work) and the target temperature is higher than that of the house. If the thermostat is showing a blank screen, it may need to have new batteries.&nbsp;<\/p>\n\n\n\n<h3><strong>Check the gas supply<\/strong><\/h3>\n\n\n\n<p>See if there is gas running to your house and to the furnace. You may need to turn on the gas valve near the furnace if you haven\u2019t used the furnace in several months. Don\u2019t attempt to tamper any further with the gas controls for the furnace.\u00a0<\/p>\n\n\n\n<p>If you suspect an issue with the gas line, look for any unusual odors like the smell of sulfur, which could indicate a gas leak. In such cases, evacuate your home immediately and contact your gas provider before arranging for HVAC repairs. Safety should always come first when dealing with gas-powered systems.<\/p>\n\n\n\n<h3><strong>Change the furnace filter<\/strong><\/h3>\n\n\n\n<p>This filter is designed to prevent debris from entering the furnace through the return air duct. Since the AC usually uses the same filter, it can be already clogged up by the beginning of the heating season. If the filter is too congested, it will often cause the furnace to shut down to avoid overheating. Put in a clean filter to see if this solves the problem. (And you should put in a clean filter at the start of the season no matter what.) <a href=\"https:\/\/www.shaferhvac.us\/blog\/heating-service\/no-heat-follow-our-guide\/\">Follow our guide for no-heat troubleshooting<\/a> if your furnace still doesn\u2019t work.<\/p>\n\n\n\n<p>At this point, you\u2019ve done all the troubleshooting to find a simple cause for the problem.
