The HVAC system in your home is designed to turn on the heating system when the thermostat registers that the household needs warmth. The thermostat signals the heater to start its heating cycle, and then it runs until the thermostat detects the home\u2019s temperature has reached its target setting. The thermostat then has the heater cycle down until it\u2019s needed again.<\/p>\n\n\n\n

As the winter temperatures continue to fall, you\u2019ll notice your heating system will run in longer cycles. This is normal: your house will lose more heat to the outside, requiring the heater to run for longer to reach your desired temperature. (We recommend a setting of 68\u00b0F, which not only makes the heater run less often but also slows down heat loss to the outdoors.)\u00a0<\/p>\n\n\n\n

But you may be experiencing something \u2026 different. A heater that seems to run in shorter and shorter cycles, shutting off early before it can heat up the house enough, then turning back on a short time later and repeating the process. Why is your heater doing this? And what can you do about it?<\/p>\n\n\n\n\n\n\n\n

Some of the Causes of a Heater Shutting Off Early<\/strong><\/h2>\n\n\n\n

To help us understand better what\u2019s happening, we need to know what kind of heating system you have.<\/p>\n\n\n\n

Heat pump\/ductless mini splits<\/strong><\/h3>\n\n\n\n

If you use a heat pump or ductless mini split (which is a type of heat pump), what you\u2019re experiencing is a problem that can often affect refrigeration systems: short cycling. The heat pump has become trapped in its start-up cycle, shutting down and starting up again and again. This wastes a tremendous amount of energy (something you\u2019ll see on your electric bills) and places a massive strain on components and leads to repairs and parts replacements.\u00a0<\/p>\n\n\n\n

There are several sources of a heat pump short-cycling. We recommend you first check on the HVAC system filter to see if it\u2019s clogged and needs to be replaced. If this isn\u2019t the source, you may have a defective thermostat, refrigerant leaks, a faulty control board, or even a heat pump that\u2019s too large for the house. <\/p>\n\n\n\n

Furnace<\/strong><\/h3>\n\n\n\n

When a furnace shuts down early, the most common cause is that it\u2019s overheating. A furnace has a limit switch that will activate to shut the system off in case it overheats. This protects the furnace\u2019s components and also helps prevent safety hazards. A furnace can overheat because of worn-down motors or poor airflow through the system that is trapping excess heat inside it.\u00a0<\/p>\n\n\n\n

Solving the Problem<\/strong><\/h2>\n\n\n\n

Unless a clogged air filter is the reason your home heating system is shutting off early, you\u2019ll need to have professionals investigate the heater to see what\u2019s wrong and how to fix it. Some possible repairs include:<\/p>\n\n\n\n
