Is My Heating and Air Conditioning Working Inefficiently?

Is My Heating and Air Conditioning Working Inefficiently?

Since the current home heating and air conditioning systems do not come with intuitive voices designed to offer you assessments about their condition, you have to do the diagnosis yourself. This doesn’t mean that you have to be a trained HVAC expert to diagnose your HVAC system’s problem.

But a little knowledge of how the system works will go a long way in enabling you to know when the system is not working efficiently. In this article, we will tell you the most common signs of defects in your HVAC system.

Exceedingly High Energy Bills

If lately, you’ve started receiving extraordinarily high energy bills that you can’t explain, you need to check the condition of your heating and air conditioning systems. Although energy costs can fluctuate from time to time depending on your energy needs, they are not supposed to increase abruptly without any good reason. If you are using an older model of the HVAC system, it could be consuming more energy than it’s supposed to. So, you should have it checked by an HVAC specialist.

Irregular Temperatures

When temperatures in the house soar or dip, we rely on our heating and air conditioning systems to regulate the room temperature and keep us comfortable. But if your HVAC system is not working efficiently, you will receive fluctuating temperatures even when you have not adjusted your thermostat. For instance, if you set your thermostat to blow cold air, but instead, you get muggy, humid air, you need to have the system checked by a professional immediately.

Unpleasant Odor

If you notice an unpleasant odor coming from your HVAC system, the chances are that you are using an outdated system. Chemical odors, burning smells, and staleness in your HVAC system are signs of internal failings. For instance, if you smell sulfur or a smell of rotten eggs, your system probably has a gas supply problem. Therefore, you should call your HVAC system repair professional as soon as possible.


If you notice unexplained drops or puddles of water in your house, most likely, they are from your leaking HVAC system. If left unchecked, leakages will have a devastating effect on your home.

Mysterious Noises

Although it’s normal for some HVAC systems to make a clicking sound, you should be concerned if your system starts to make loud banging, squeaking, whizzing, or clattering noises. Most of these noises indicate that your system needs repair, retrofit, or replacement.
