Heating and cooling account for almost half of your yearly utility expenses. If you are conscious of how much money you spend on your electric bill, you want to make sure your HVAC system is at its best.

When you depend on your HVAC system to keep your home at a comfortable temperature, you don’t want to be caught off guard with problems.

Are you worried that your HVAC system is on its last leg? Stick with us to learn the 5 warning signs of an HVAC failure you won’t want to ignore.

1. High Utility Bills

If you notice more than the normal energy bill fluctuations, it might indicate that your HVAC unit is the source of the increase. Take notice of any other changes that may account for higher utility bills like company staying with you or a long spell of extreme temperatures.

It could be that your unit is not working as well as it once was and has to expel more energy to cool or heat your home.

2. Strange Noises

Do you hear banging, grinding, squealing, screeching, or grating noises coming from your HVAC unit? This is a sign that there may be a problem.

Your unit should run fairly quietly with no more than the sound of air flowing in the background. If not, have it checked out to figure out the issue.

3. Weird Odors

There are three types of odors that may raise concern. A rotten egg smell could be a natural gas leak. This is extremely dangerous so call a professional immediately.

A musty or moldy smell may indicate moisture in the ducts. It is not safe to breathe moldy air so the problem needs to be handled ASAP. A professional can find the source of the moisture and clean the ducts.

An electrical or burning smell could be an electrical problem with the motor. This is another emergency situation as it could cause a fire.

4. Uneven Heating or Cooling

HVAC capacitor failure can lead to your air conditioner quickly stopping and starting because the capacitor is responsible for sending electricity to the unit. This stopping and starting will cause uneven heating and cooling.

You may also notice some rooms are hotter or cooler than others if your HVAC system is no longer working as efficiently as it once was.

5. Leaking Water

Have you noticed a puddle or damp spot or mold? These are signs of refrigerant leakage or some sort of blockage. You’ll want to have a professional locate the leak or blockage before you experience more damage to the home.
