What to Do in the Middle of an HVAC Emergency

How can you tell if your HVAC system needs emergency servicing? It depends on whether the issue poses safety or health risks to your family. For instance, in the winter, insufficient heating or an HVAC leak would be considered HVAC emergencies. 


What are the warning signs you need to keep an eye out for? And what should you do when you encounter them? Cafco Services, one of the area’s most trusted HVAC companies, explains in this guide. 

The Warning Signs of an HVAC Emergency 


  • A burning smell – If you smell burnt wiring, turn off your HVAC system immediately and call a professional contractor. Burnt wiring poses a fire hazard and should be replaced as soon as possible. 

  • Unusual noises – Strange noises coming from your HVAC system are never a good sign. They’re usually caused by damaged components. If the malfunctioning components aren’t fixed or replaced immediately, your HVAC system could break down, which is the last thing anyone wants to deal with in the middle of winter. That’s why you need to schedule an HVAC inspection as soon as possible. While waiting for the HVAC contractor to arrive, it’s best to turn off the HVAC system to mitigate damage. 


Here’s a tip: it’s a good idea to write your HVAC contractor’s contact information on a sticky note or keep it in your phone. That way, you can contact them immediately in case of an HVAC emergency. 


Issues That Don’t Need Emergency Servicing 


What doesn’t qualify as an HVAC emergency? 


  • General repairs when outdoor temperatures aren’t too high or low 

  • Cleaning or replacing the air filter 

  • Installation of HVAC upgrades 


Preventing HVAC Emergencies  


Routine maintenance is the best way of preventing HVAC emergencies. As a rule, your HVAC unit should be inspected twice a year, ideally before the start of summer and winter. The air filter should also be replaced with new HVAC filter products every three months.
