Common Furnace Problems Your Unit May Encounter


Understanding all of the problems that could potentially impact your home's furnace can seem like a daunting task, but there are steps that can help to make it easier for a homeowner to feel comfortable with handling malfunctions with this critical piece of equipment.

Compromised Or Malfunctioning Sensors

Your home's furnace system will have a number of different sensors in it that will help the unit to regulate its performance. For example, some of these sensors may monitor the temperature of the furnace itself to ensure that the system is not at risk of overheating. Conversely, other sensors may verify that the pilot light is burning correctly. Problems with these sensors can lead to extremely unusual performance behavior from the system, such as rapidly cycling between on and off. While these sensors can be replaced, it will need the skills of a trained professional to ensure that these sensors are properly installed and calibrated so that they are providing accurate readings to the furnace.

Fuel Flow Problems

A gas or oil furnace will require a steady supply of fuel to keep it running. Any problems with the fuel line can prevent the furnace from being able to produce heat as the burner will face interruptions to its fuel supply. Repairs to the fuel line of the furnace can be among the most critical to do correctly. Otherwise, there could be a greater risk of the system developing a gas leak that may pose an imminent health and safety risk. While you may not be able to effectively repair issues with the fuel line on your own, you will be able to recognize some of the warnings that this problem is emerging. One example of this problem can be the furnace periodically turning off or simply stopping the production of heat.

Excessive Amounts Of Condensation

Condensation can be a frequent cause of corrosion developing on a furnace system. When corrosion starts to form on these units, a homeowner may attempt to ignore this problem. Yet, the corrosion can gradually weaken the integrity of the furnace's housing and mechanical components to the point where the entire system stops working. While a furnace repair contractor will be able to replace many of the important components that have developed corrosion, you will have to take steps to address the condensation issue. Often, this will require the installation of a dehumidifier in the area near the furnace. These systems can remove much of the moisture from the air before it is able to form condensation on the metal components of the furnace.

steps for preparing your air conditioner for use

So many of us make the mistake of assuming the air conditioning system is up and ready to go without having to do anything after a long winter. Unfortunately, oftentimes, this isn't the case. You know how I know that air conditioning systems need pre-summer maintenance? Well, I know because I broke my air conditioning unit trying to use it without even looking at it before starring it up for the first time. It was that moment that I learned a very valuable lesson the hard way. My blog will walk you through getting your air conditioner ready for summer without the expensive lesson that I had to learn.
