One of the most common questions people have when it comes to their air conditioner not working properly is, “Why is my AC blowing warm air?”

If you suspect that your air conditioning system is on the fritz and not working as it’s supposed to, how do you know if your AC problem isn’t critical and that you might be able to fix it yourself? Alternatively, when should you leave the repairs to the professionals?

Check out the below scenarios to help you identify how to troubleshoot common issues yourself and when it’s a good idea to call in a professional HVAC technician to help with your AC woes.

Why is My AC Blowing Warm Air?

One of the most common problems homeowners experience is when an air conditioner is blowing warm or even hot air. Most of the time this is due to a dirty or clogged filter, or because thermostat settings are incorrect or the batteries have not been changed in some time. For an easy fix, try replacing your filter or adjusting the thermostat with new batteries.

If you’re still noticing that your unit is blowing warm air even after making simple changes, or your AC is making strange noises, it’s time to call in an HVAC tech who can perform a thorough assessment to check for bigger issues such as a compressor problem or refrigerant leak.

When It’s Time to Call an HVAC Tech

For air conditioning issues such as leaks, the unit not shutting off when it should, the fan continuing to run, or if the unit is making loud and strange noises, a simple filter change or cleaning of the unit may not be helpful. This is when it’s best to call an HVAC technician rather than try to inspect and repair it yourself. A tech will make sure the repair is done safely and correctly first time.

Here are some additional situations in which it’s better to call in a tech:

  • Components Need Replacing. A minor component failure can sometimes lead to a major component failure down the line. HVAC technicians can check components such as contractors or ignitors (which are susceptible to failure) and make sure they’re operating within specified levels. Replacing these items leaves you with a better running system that’s safer to operate.
  • You’re Getting Thermostat Alerts. Thanks to improved technology, smart thermostats can alert you when something out of the ordinary is happening with your system. Take note of what these thermostat alerts are reporting and if it’s something beyond a filter change or battery fix, call an HVAC technician who can professionally and safely handle the problem for you.
  • You’re Expanding or Buying a New Home. Finding the right sized system for your space is something best left to the professionals. It requires the right calculations and knowledge of the various HVAC systems and products available. A system that’s too small can cause extra wear and tear, resulting in a limited lifespan. Alternatively, an oversized unit can cause stress on the equipment and create extra energy costs for you. Trust in an experienced HVAC technician to keep you on track.

Keep Up with Regular Maintenance

The best recommendation is to have an HVAC technician perform regular maintenance on your AC system, roughly once a year, not only to increase the longevity of your unit but also to ensure everything is working properly and catch small issues before they become bigger problems.

This is especially important if your system is under warranty. A HVAC manufacturer could void your warranty if regular maintenance isn’t performed. Whatever the problem, don’t hesitate to call in a professional HVAC technician if you are unsure about anything or want a second opinion on a suspected issue.
