If you just purchased a house with a furnace, here are three common issues that many furnaces experience as well as some advice on how prevent them.
#1 Clogged Filters
One of the biggest issues that most furnaces experience are clogged air filters. Many users forget to take care of the air filters that are an integral part of their furnace.
A clogged air filter will reduce the airflow throughout your furnace. This will cause your furnace to have to work harder to provide your house with warm air. Over time, a severely clogged filter that is not fixed can even cause damage to the fan inside of your furnace and the limiting switch.
You can very easily prevent all of these problems by simply cleaning the air filter in your furnace on schedule and replacing it when needed. When you purchase a filter, the packaging should tell you if you can clean the filter and how long you should use the filter before you replace it.
Make sure that you mark this information on a calendar or set a reminder on your smart device so that you can keep track of when to change the filter. Since this house is new to you, it's a good idea to just replace the filter as soon as possible so you know when it was installed and when it will need changed again.
#2 Pilot Control Problem
Another common issue with furnaces are the pilot lights going out. This generally happens because the pilot lights gets blown out by a gust of wind or a stray breeze. These should be a guard around your pilot light to keep it from getting blown out. If there is not a guard present, you are going to want to have one installed.
Next, you are going to want to make sure that there are not any drafts blowing through the area where your furnace is located. Make sure that all your doors and windows are properly sealed so that no stray drafts blow out your pilot light on a continuous basis.
#3 Cycling Off Too Frequently
One of the last issues that many furnaces commonly experience is cycling on and off to frequently. This issue can be caused by a number of different things. Most commonly, the issue is caused because of a clogged air filter, which can be solved by cleaning and replacing the air filter on time as address in point number one.
However, cycling on and off too frequently can also be caused by the air flow not working properly in your furnace. There could be an air duct that is damaged, or you could have closed vents inside of your home that are preventing the air from cycling as it should throughout your home. You'll want to inspect your ductwork and all of your vents to make sure that the air is flowing properly through all of them.
Finally, your furnace could be cycling on and off more than it should because your thermostat is not set at the proper temperature. Sometimes, adjusting the temperature of your thermostat is all that you need to do to stop your furnace from cycling on and off all the time.
