If your home has a central HVAC system that takes care of its heating and cooling, then you need to have a full understanding of what is normal, what possible issues can come up that you can take care of on your own and what problems may come up that you want to call out a professional technician to take care of for you. You can reference this article as a helpful guide to have a better understanding of your air.
What you can normally expect – You can normally expect a central HVAC unit to keep the entire house at the same temperature; the temperature you have set the thermostat to. This type of system is designed to maintain this even flow by forcing the air through the registers throughout the house. Even though these registers can be adjusted to the point of closing them off, you should never completely close any of them or it can cause problems in the system.
You can expect the system to temporarily stop when the desired temperature has determined to have been achieved and restart once the temperature rises or falls by a certain number of degrees. You can expect to hear the unit each time it kicks back on, but this should be a mellow whisper of a sound.
What you can take care of on your own – If your HVAC air system is on, but you notice it isn't actually kicking on, then it could be frozen. You want to turn it off for at least a few hours and then turn it back on once it is no longer frozen. If your entire system is completely off, then the fuse may have blown. You can check the fuse box and reset the fuse in order to get the system back up and running again.
When you need a technician – If you hear any strange noises coming from your unit, there are any strange smells coming from it or it isn't working and your own troubleshooting can't find an issue you can take care of, then you want a technician to come out. A central HVAC system is not something that you want to experiment with on your own if you don't have the knowledge to take care of whatever may be wrong with it. This can cause big problems including worse necessary repairs, full replacement or even you to get shocked. Contact a service, like Advanced Heating & Cooling, for more help.
