As winter approaches and temperatures start to drop, you’ll want to make sure that your furnace is in good working order. But even if you take steps to maintain your system all year long, there are still several common issues that can arise with your furnace. Read on to learn the five most common furnace problems.
Malfunctioning Heat Exchanger
The heat exchanger is responsible for transferring heat from the burners to the air coming through your vents. When this part malfunctions, it can cause significant problems such as decreased energy efficiency, increased gas usage, and even carbon monoxide release. As this malfunction can have various causes, addressing it requires professional HVAC technicians that can assess the situation and provide adequate solutions.
Bad Limit Switch
The limit switch monitors the temperature of the air coming out of the furnace and tells it when to turn on or off. If this switch malfunctions, it can cause your furnace to run too long or stop running altogether. A bad limit switch can also cause other problems such as excessive heat or cold spots throughout your home. To solve this issue, you will need to have an HVAC technician come in and replace the limit switch with a new one.
Tripped Circuit Breaker
If your furnace has stopped working suddenly, it could be due to a tripped circuit breaker. This happens when too much electricity passes through one circuit, causing the breaker to trip and shut off power to whatever appliance was connected at that time. To reset a tripped circuit breaker, simply turn off all appliances connected to it and then turn on one at a time until all are back up and running again.
Dirty Filters
Dirty filters restrict airflow, so if yours haven’t been changed in a while, they could be contributing to reduced efficiency and potential health risks from inhaling airborne particles like dust, pet dander, and mold spores that get trapped inside them. To fix this issue, simply replace any old filters with new ones every one to three months or so depending on how often you use your furnace.
Unusual Noises
Your furnace should usually operate quietly, so if you start hearing strange noises coming from it, such as banging, squeaking, or humming, there is likely an issue with one of its components. These noises are often caused by worn out fan belts, loose parts, poorly lubricated motors, and other malfunctions that require professional attention. An experienced technician will be able to identify and repair any underlying issues quickly and efficiently.
Why is My Furnace Leaking Water?
If you have noticed a pool of water around your furnace, you may be wondering what could be causing the leak. While it’s definitely best to call an HVAC professional to inspect and repair the problem; here are some possible reasons why your furnace is leaking water.
Clogged or Frozen Condensate Line
Your furnace produces condensation as a byproduct of running, and this condensation must be drained away from the unit. If the drain line becomes clogged or frozen, the condensation will begin to build up inside the unit and eventually cause it to leak.
Dirty Furnace Filter
The filter works by trapping dirt, dust, and allergens in the air that can cause respiratory issues, while allowing clean air to pass through and heat your home. Unfortunately, when the furnace filter becomes clogged and dirty, it can often cause a water leak due to the pressure put on the ducts and pipes leading to the unit. Plus, too much pressure on the furnace itself causes additional strain that could possibly lead to leaks if not taken care of right away.
Broken Blower Motor
A broken blower motor could be the cause of the leaking because it is responsible for moving air through the unit and out into the home. If it’s not functioning properly then you might find that warm or cool air is escaping from the unit and if left unchecked, can result in water damage.
