Three Signs Your Furnace Needs To Be Serviced
Furnaces share the designation as the most important appliance within your home with your air conditioner, trading the title as the seasons change throughout the year. Just like all other appliances, your furnace can be subject to malfunctions and degradation through the normal course of operation, which can negatively affect how well your furnace performs. Understanding some of the warning signs associated with a furnace that is overdue for repairs can help you identify when you need to contact a HVAC professional to inspect and service your unit.
Increased Monthly Bills
One of the surest signs that you need to have your furnace serviced or repaired is if you notice that your monthly energy bills have increased markedly, while your overall use of your furnace has either stayed the same or even decreased. This points to the most obvious signs that your furnace is no longer operating as efficiently as it had in the past, which means that it has to use more energy and operate more often to provide the same amount of heat. There are a whole host of things that can be affecting your unit's efficiency, so if this is the case, getting a holistic examination of your furnace should be your first step.
Constant Switching On and Off
Another fairly clear sign that your furnace is in need of repairs to restore its effectiveness is if you notice that your furnace is turning itself on and off multiple times within a short period of time, such as several times within a single hour. This can point to a malfunctioning thermostat, a clogged air filter, ducts that are drastically in need of cleaning, or in rare cases, the burning out of the heating element itself (which will, unfortunately, require the entire appliance to be replaced, most likely).
No Air Flow
Finally, another sign that you need to have a professional come in to check on your furnace is if you notice that there is no air flowing out of your air vents and registers throughout your home, even though they are completely free of dust and unblocked. This can either point to a blockage deeper within your ductwork, which will require cleaning to remove, but more commonly will point to a fan or blower that is no longer working properly. This can lead to the cycling on and off mentioned above, and higher energy bills, as your furnace will be unable to distribute all of the heat that it is producing, while the thermostat will continue to tell the unit that the house is getting cold despite its constant operation.
