When Do Furnace Issues Require Professional Help? Insight from a Warrenville Heating and Air Conditioning Company


When a furnace is properly installed and maintained, it can run smoothly for years. But what happens when performance issues start to occur? In some cases, you may be able to solve these issues yourself, while in others, you may need professional help. It’s important to know the difference between these two situations, and the signs which tell you that the issue is a little more serious. Here is what you need to look for:

1. The Problem is Related to the Electrical System

If you are having issues with your heating and air conditioning system, and if you start to notice your home’s electrical system acting up as well, then the two may be related. For example, if you notice that your lights dim slightly when you turn your heating and air conditioning system on, any performance issues with the system may be related to your electrical wiring or components. In this situation, you will definitely want to speak to a professional in order to properly diagnose and address the issue.

2. Furnace is Very Loud or Making Unusual Noises

There will be situations when the furnace is running optimally, but it makes a lot of noise in the process. If you can trace the issue back to your ductwork, the solution can be to insulate the ducts in order to reduce the noise. However, if the noise is coming from the furnace itself, then the issue may stem from a lack of oil in the motor lubrication ports, or from an improperly adjusted pilot light.

Other noises may indicate different problems with the system. For example, if you hear pinging and popping sounds, the issue may be caused by the ductwork expanding and contracting as it heats and cools. Rattling noises may be caused by loose panels. Squealing noises indicate that there is a problem with the way that a belt connects to the fan motor. Grinding sounds are the most indicative that you’ll need to call technician soon, as the problem may be with the motor bearings.

3. Warrenville Heating and Air Conditioning System is Turning On and Off at Short Intervals

When a furnace turns off and on quickly, it is going through what is called rapid cycling. There are many causes for this issue, ranging from a worn-out or dirty air filter, to issues with the compressor. Replacing the air filter is easy, and with a bit of DIY experience, most homeowners can tackle the project. However, if the problem persists after the filter is changed, then the issue may be a more serious one. In this case, you’ll want to call a professional contractor to have a look at your furnace.

4. There Is an Unpleasant Smell in the Home

There are several reasons why your HVAC system might start to generate an unpleasant odor in the home. One is related to the filters, which can start to spread a smell in the home when they are dirty or clogged. Another reason stems from the ductwork, where dust and other particles accumulate over time, and which need to be cleaned periodically. Both of these issues may be resolved through a DIY project. However, if you start to smell rotten eggs or Sulphur, then the problem may be more serious — it could be a gas leak. In this situation, you’ll want to stay on the safe side by opening all your windows, shutting off the gas valve, and immediately calling an HVAC contractor. It’s strongly recommended that you leave the home and do not use any electrical devices inside until the problem is fixed.
