You know to 9-1-1 in a medical emergency, but who do you call for an HVAC emergency? And what is considered an HVAC emergency, anyway?

If you’re having issues with your heating and cooling system, read this article. Below you’ll find which HVAC issues are an emergency.

Screeching Noise

Where is that whining, screeching noise coming from? If the answer is your HVAC system, you have a problem.

The noise is probably coming from too much pressure in the compressor. When pressure builds up it can damage the compressor and in rare cases may explode. Contact an HVAC expert right away. 

Electrical Issues

Does your HVAC trip the circuit breakers in your home? Or have you noticed a burning smell coming from the unit? If so, call HVAC emergency services.

When it comes to potential electrical issues, it’s not safe to try to address the problem yourself. An HVAC company can send out a representative to quickly and efficiently diagnose and fix the problem.

Bad Heat Pump

When a heat pump does not defrost properly, it won’t work. The coils and fan need to be clear for the HVAC system to heat the home properly.

You can check your automatic defrost settings but if that doesn’t work, call an HVACA professional to remove the frost build-up and restore heat.

Strange Odors

Any strange odors coming from your HVAC should be reported to a professional right away. The source of the odor could be a dead animal in the ducts or even a gas leak. If you notice odd smells coming from the unit, turn it off, and open some windows before calling for emergency repair.

Not Turning On

There is nothing worse than discovering your heat won’t turn on during a cold winter night. If the unit simply won’t turn on at all, you should call HVAC repair. There are a number of potential issues that could be causing the lack of power.

Remember that cold temperatures are not only uncomfortable; they can be dangerous for infants and the elderly.

Experiencing Indoor Humidity

Indoor humidity levels should always be between 30% and 50%. When the humidity levels rise, your home is more likely to grow mildew or mold, which can be dangerous for your health.

If you notice that the humidity is higher than usual and adjusting the settings on your HVAC isn’t helping, call an HVAC repair company.

Steam/Water Around Boiler

When the boiler has a broken valve or a crack, you may notice steam or water accumulation. Call for repair right away. Water damage from a broken boiler could hundreds or thousands of dollars to fix.

Remember that your HVAC needs regular maintenance to keep it running. Schedule an annual spring tune-up to get the most out of your HVAC.
