Why is The Heater Not Working When The Thermostat Is On?
There are a few things that could be causing your heater to not work when the thermostat is on. One possibility is that your thermostat is not set to the correct temperature. Make sure that the thermostat is set to heat mode and that the temperature is turned up high enough to activate the heater. If your thermostat is set correctly, another possibility is that there is something blocking the airflow to the heater. Make sure that nothing is blocking the vents in your home. Finally, if everything else seems to be ok, it might be time to call a technician to inspect your heater.
Is Your Heater Not Working?
Heaters can have a wide range of problems that prevent them from working properly. Knowing what you’re looking for when diagnosing a problem with your heater can help you determine if you can fix it yourself or if it needs professional attention from a technician. In many cases, simple things like cleaning the filter or clearing debris from airflow will solve issues with getting your heater back up and running again. However, sometimes there are deeper issues at play such as electronics failures inside the heater itself which require professional service.
Technical Problems that Keep Furnaces from Bringing the Heat
- A blocked or dirty intake provides less airflow to the heater, thus making it harder for the system to heat your home properly. In some cases, debris can build up inside the unit itself and create a fire hazard. This is especially important if you have been having issues with shutting down unexpectedly during times of operation.
- Trying switching from heat mode to cooling mode and then back again. Many thermostats will flash “HI” when trying to reach a certain temperature that is much hotter than what was previously set on the thermostat. Sometimes this causes confusion over whether it’s in heating mode or not.
- The fan on the outside of the house is not running. This fan is responsible for pushing heated air out of your home and can be caused by a number of things such as a failed motor or clogged filters.
- Something is physically blocking the flow of air to the unit. This could be something as big as a piece of furniture that was accidentally pushed in front of the vent, or something small as a spider web that has formed inside the intake grill.
- The thermostat isn’t set to heat mode. Some thermostats have both cooling and heating capabilities, but require that you specifically tell it which one you’re using.
- There’s an issue with the wiring. The wiring from your thermostat to your furnace can go bad over time, especially if it’s an older home. This can cause the furnace to not turn on at all or to malfunction in other ways.
- The circuit breaker that your furnace is plugged into has tripped. If this happens, the furnace will not turn on no matter what you try. You’ll need to trip the breaker back on in order for the system to work again.
- Your furnace is too small for your home. If you’ve never done an energy audit and don’t know how much heating capacity your home needs, it might be worth consulting with a professional to find out. Oversized furnaces can waste a lot of energy and money, while undersized furnaces can lead to insufficient heat and uncomfortable conditions.
- The thermostat is bad. Believe it or not, thermostats do go bad and can cause all sorts of problems with your heating system. If everything else seems to be ok, it might be time to replace your thermostat.
If There’s No Gas, The Heater Won’t Be Working
If you have a gas furnace, another issue that can cause the unit to not work is if there is no gas getting into the unit. This may be caused by a number of things including faulty or mislabeled piping at your local utility company, bad valves on the line, or even damage to one of the lines between where it comes in from the street and where it connects to your furnace.
The Furnace Needs Maintenance
If you’ve had the same furnace for a long time, sometimes it’s just worth getting some maintenance work done on it to prevent having to replace the unit entirely. While gas furnaces usually come with a 10-year warranty that covers parts and labor, if your furnace is an older model or has been giving you trouble over the years, this may be the best way to go in order to keep yourself warm all winter.
Every year, we recommend two tune-ups. One before the start of summer and one before the start of winter for your air conditioner.
During a furnace tune-up, our skilled HVAC professionals will examine every aspect of your system to ensure that no component is overlooked. Every heat pump is different, and our experts understand that everyone requires special treatment.
Have You Changed The Air Filter?
Another important part of regular furnace maintenance is changing your air filter. This helps the furnace run more efficiently and also ensures that the airflow is strong enough to push heated air out into your home.
If you don’t know how to change your own air filters, It might be worth hiring us because we provide professional HVAC services. Knowing how often you need new filters can help you save money, but getting them changed regularly will ensure that the system remains efficient throughout the year.
Is Your Furnace Short Cycling?
If your furnace is short cycling, it means that it’s turning on and off more often than it should be. This can be caused by a number of different things but is usually indicative of a problem with the furnace itself.
Sometimes your furnace short cycles if:
- Your Furnace is too big for your home
- The furnace itself is overheating
- Your flame sensor isn’t working
- The air filter is too dirty and too full of debris
- The thermostat is in the wrong spot
