The cooler temperatures are finally here \u2013 thank goodness! Now, it\u2019s officially time to give our air conditioners a break, and soon we may even have to crank up the heat. But, what if nothing happens when you switch your thermostat from \u201ccool\u201d to \u201cheat?\u201d Here\u2019s what to do.<\/p>\n
Heater failures are a common problem in the fall \u2013 primarily because they\u2019ve been sitting unused for many months. Often, a problem isn\u2019t discovered until it\u2019s time to turn on the heat. The reality is that there are many reasons why your central heating system isn\u2019t working. In some cases, it\u2019s a quick do-it-yourself fix. But, most of the time, you\u2019ll need to call a professional.<\/p>\n
If you can hear your heater working, but feel no hot air, it could be a lack of airflow caused by buildup of debris and dust. Often, a simple swap of an air filter can do the trick.<\/p>\n
If that doesn\u2019t solve the problem, it\u2019s time to take a closer look at the thermostat. If it\u2019s switched from \u201cheat\u201d to \u201ccool,\u201d your heater won\u2019t turn on. It also can be prevented from turning on by a timer setting. If someone has been \u201cmessing\u201d with the thermostat, check the programmed settings to make sure everything is set as it should be.<\/p>\n
If those simple fixes don\u2019t work, you could be dealing with a larger problem. Common causes of a central heating failure are:<\/p>\n
Check to see if the outside components are clear from debris, leaves, branches and dirt.<\/p>\n
Without the blower pushing hot air into your home, you might be getting gusts of cold air.<\/p>\n
Like a malfunctioning blower, leaky ductwork hinders the ability to move hot air to warm living spaces.<\/p>\n
