Sometimes, you find yourself dealing with a serious problem with your HVAC system because you put off a repair or other attention that your system needed. However, you might end up finding that you are dealing with a sudden and surprise problem, no matter what kind of regular maintenance you've been doing. No matter what has caused you to end up with serious HVAC problems, it will be exceptionally important for you to recognize when you are in the midst of a serious situation and for you to have it taken care of right away. Here are some examples of situations that should be taken care of right away and considered to be HVAC emergencies. 

No air conditioning in an extreme heat

In some regions, having the AC go out can be an inconvenience. However, in other regions, it is considered to be an actual HVAC emergency. Also, no matter where you live, if your area is dealing with a heatwave, then having a broken air conditioning unit would still be considered to be an emergency. If your home is going to be at a temperature that's uncomfortable and unmanageable with fans, then you should be having someone come out on an emergency call. 

No heater in the extreme cold

If you can't get the heat to work and your house is very cold, then you want to have someone come out to deal with your HVAC emergency. The weather can be cold enough to call for an emergency visit in just about all regions when a cold front has moved in. However, in some areas, a non-functioning system would be considered an actual emergency at any point in the winter because the temperatures can drop below freezing at any given moment. 

There is a possibly hazardous situation

Any time you find that something is going on with your heating and/or air conditioning system that may indicate there is a possibly hazardous situation, then you want to make sure you call for someone to come out for an emergency HVAC visit right away. Smells can indicate there is leaking gas that needs to be dealt with. You will want to turn off the gas, and then get everyone out of the home until things have been inspected. Smoke also needs to be taken as an immediate emergency, as does something like seeing sparks.
