With summer approaching, it is essential to make sure that your HVAC system is in perfect working condition. Any problems you may have now will only get worse as the hot weather starts to put extra stress on your unit. 

So how can you tell when it is time to make a phone call to your local HVAC maintenance technician? 

This article will give you 5 HVAC maintenance tips that will help identify problem sounds in your system. 

1. Unusual Sounds

The only sound your HVAC unit should be making is a continuous, low hum. If you hear any other type of noise, it is time to call an HVAC service. Here are some common noises you may want to look out for, and what they may indicate. 

  • Screeching/Whining: excess pressure on your compressor or a misaligned fan belt.
  • Popping: Electrical issue.
  • Thwapping: Something caught in the machine.
  • Clicking: Persistent clicking can indicate so many different issues, you will need professional HVAC repair to diagnose the problem.

2. Burning Smell

Even a temporary burning smell is an indication of a serious electrical problem. You may only notice the burning smell for a few seconds when you turn it on, but even this is a serious warning. The problem will only get worse as the machine works harder in the summer. And the smell may occur while you are not near the machine. 

If you notice a burning smell, turn off your HVAC system immediately and call an HVAC company near you as soon as possible. 

3. Ice on Your HVAC

If you see ice on your HVAC, it means that there is a problem with your refrigerant, usually caused by a lack of airflow in your system.

You may be tempted to think that a little ice on your HVAC is nothing to worry about. But the ice build-up will only continue to grow. If left unchecked, ice can grow to cover your entire system, blocking airflow altogether. 

4. Higher Energy Bill

It’s expected to see a spike in your energy costs each summer. But if you are raising your eyebrows at the energy bill each month, wondering why this year is more expensive than the last, your HVAC could be the culprit.

Even if you don’t notice any other symptoms, it’s worthwhile to call an HVAC service to make sure there’s nothing going on. 

5. Not Enough Air Flow

If you notice a drop in the airflow coming from your air conditioner, it’s a good sign that it’s time to call for an HVAC repair service. 

It may be that something is stuck in your system. You may want to save money and go looking for the blockage yourself. But that blockage could be anywhere and could be much smaller than you think.
