Warning Signs That Your Heating System Is Failing

Having your heating system go out in the dead of winter can be a nightmare. Not only is it unpleasant to be extremely cold in your own home, but the lack of heat can cause significant problems around the house. It can also even cause health risks.

The unfortunate reality is that many people overlook the signs that their heating system is about to fail, sticking them with a dead heater in winter, and causing HVAC repair specialists to be in high demand. Because of the high demand, repairing your heater might be more costly. That’s why it’s best to take pre-emptive steps to ensure your heater won’t break down when you need it most.


Heaters aren’t necessarily supposed to last any longer than 15 years. Some last up to 20, but that’s about the maximum amount of time they can function. If you don’t know the age of your heating system, it’s best to find that out before winter. Many systems have an actual installation date on them somewhere. Some have a code displayed that indicates when the parts were made. It’s also possible to contact the prior owner of the house (if applicable) and ask them when the heater was installed. If the heater was installed close to 15 years ago, it’s a good idea to replace it before winter comes.

Utility costs

If you experience higher-than-normal utility bills, it’s a strong indicator that your HVAC system is failing. This applies to both air conditioning and heating. For example, if your house is adequately warm during the winter, but your first utility bill is sky-high, that means that your heater isn’t working efficiently. Although it might seem to be working, and it might be keeping the house at a pleasant temperature, it’s starting to lose its power. This is a good sign that your heater is declining.

Cold air

If your heater is pumping out cold air, that’s another sign that something is wrong internally. It’s functioning in the sense that it’s pumping out air like it’s supposed to. But, if you have the thermostat set to 72 and the air coming out of the vents is chilly, there’s something wrong. This can also lead to high utility costs due to the heater’s inefficient heating. At first, it might seem like the thermostat needs to be set at a higher level, but all that does is waste energy and increase your bill. In the event your heater is emitting cold air, it’s time to replace it.

It’s wise to take a close look at your heater before the winter months to save yourself the trouble of having to find HVAC repair in Marietta at a dire time.
