It's always better to catch heater problems as soon as they start and to have them fixed as soon as a technician is able to tend to the system. There are many things that can start happening to your heater that should warrant quick attention. Below are examples of a few of them, but know that any change should be considered a possible problem.
Sudden uneven heating
In some cases, there can be rooms in a house that seem to stay cooler than others, even with the heater on. There are reasons for this in some cases. Rooms can stay cooler because they are on the shaded part of the house because they are the rooms with hard floors, etc. However, if your heater has always heated the home up evenly and all of a sudden it no longer is, then it is a good idea to have a tech come to take a look at things.
Turning on and off too frequently
In most cases, a heater should come on about every 15 minutes. You'll get to know your system and this can help you notice if the system seems to be coming on more than it should. Pay attention if you think the heater is coming on too often and make sure it doesn't turn on more than four times in one hour. If you notice it coming on more often, have it looked at, it likely needs repairing.
Smells from the vents
You will smell an odor of burning dust the very first time you use the heater for the season. However, after this, you shouldn't have any smells coming out of the vents. If you do smell weird or even bad smells being blown out of the vents, then a technician should come to check things out for you.
Sounds start to be heard
You'll hear normal sounds when the heater is and this includes the sound of the heater coming on and other small noises that your heater might just have. However, there is no reason why a heater should all of a sudden start to make noises that can include squeaks, squeals, bangs, thumps, clicking, or any other types of noises that have never happened before to your knowledge. Have a tech come out and explain the sounds to them and tell them where the noises seem to come from. This will make it a little easier for them to narrow things down right away, so your heater can be quickly fixed.
