WHAT CAUSES OF MY HEATING SYSTEMS TO SHUT OFF FREQUENTLY?
Clicking noises when heating are not only annoying, they can also be worrying! So what exactly could be the cause of heating systems to shut off? To answer this question, it is important to understand how a heating system normally works.
HEATING SYSTEM CYCLE FOR TEXAS HOMES
The average on/off cycle of a heating system is three to six times per hour. Most homes in Texas have a central heating system, such as a furnace. The furnace turns on and off based on signals from your thermostat. When your thermostat detects that it is too cold, your heater turns on. And as soon as it is warm enough, your heating switches off. It is normal for this cycle to occur several times per hour.
When a unit goes through its cycles more frequently, we say it is a short cycle. Short cycling is exactly what it sounds like: the on and off cycle occurs faster than expected. A short cycle furnace definitely needs repair. Short cycles are not only audible, but they also cause additional wear and tear on your system and shorten its lifespan. This is also the cause of above-average energy bills.
WHY YOUR HEATING SYSTEM IS SHUTTING OFF ALL THE TIME
Instead of requesting heater repair Jacksonville right away, you have the option to determine the root cause of the short cycle and fix it. Here are some things you should check:
THERMOSTAT CAUSING MIXED SIGNALS
Since your thermostat sends signals to the furnace, this is a good starting point for troubleshooting. First, check the thermostat and make sure it is set to heat and the correct temperature. Next, check to see if the thermostat detects additional heat. For example, is your thermostat exposed to direct sunlight? Or is it possible that there is another heat source nearby that is causing strange readings? Space heaters and even hair dryers used close to the controls or thermostat can give the impression that the home has reached the set temperature and cause short cycles.
CLOGGED AIR FILTERS
You should replace the air filters at least every three months. However, if you have a lot of people or pets in your home, check them every month. A clogged filter is one of the most common causes of short cycles. Without proper air circulation in the system, the warm air cannot circulate throughout the home as it should and the result is a cold home. The device works more than it should without providing the desired comfort, which can lead to mechanical problems.
OTHER REASONS FOR YOUR HEATING SYSTEM SHUTTING OFF REPEATEDLY
Why else could your heating system switch off? Furnaces are complex mechanical systems and there are hundreds of components that can cause them. Other causes of short cycles in a heating system include:
- Undersized ductwork or equipment
- Corroded flame sensor
- Objects lodged in air vents or chimney
- Dislodged air ducts
- Low refrigerant in a heat pump
