Any problems with the furnace of your home can have substantial impacts on the comfort of those in the house. When these problems arise during the cold winter months, it can lead to the interior temperature rapidly dropping if a homeowner is not prepared to address the issue.
Obstructions In Ducting Or Vents
A forced-air furnace can be extremely effective at warming your home. However, it can be possible for the ducting or vents that transport the hot air to become obstructed. Typically, this issue will manifest as one room or a particular section of a home being significantly cooler than the other areas. While it may be possible for you to remove obstructions that are near the openings of the ducting, it can require a professional to find and eliminate obstructions that are deeper in the ducting. This problem is particularly common for homes that have their vents along the floors as it can be much easier for items to fall into them.
Forced Air Blower Failures
To move the air from the furnace through the ducting, there is likely a forced air blower. This is essentially a very powerful fan that will be able to move air throughout the entire ducting system in your home. A major blower failure can force the air coming from the vents to completely stop. More minor blower issues may result in the air from the ducting getting progressively weaker the further away from the unit. This can be extremely noticeable in a home that has a second floor or a ranch-house layout as these designs will have rooms that are much further away from the furnace.
Damage To The Heat Exchanger
The heat exchanger is a critical part of the heating system. This unit will be responsible for transferring the heat that is being produced by the furnace to the air that will be circulated throughout the home. To accomplish this, a series of tubes will be used to heat the air as it moves through the system. Unfortunately, it can be possible for the heat exchange components to suffer cracks. These cracks can allow the heated air to escape, and this may result in the air from the furnace being significantly cooler than normal. Due to the extreme heat that the exchanger will have to endure, it is typically best to simply replace a heat exchanger that has cracked due to the high likelihood of the patch failing fairly quickly in response to the thermal stresses.
