Most households have some form of air conditioning system. The issue with this is that most households may not know what to do when that air conditioning unit is no longer cooling. All you may notice is that it is not cooling, the fan is blowing without cool air, or that it isn't turning on at all. What you may not know is what to do when this issue happens and before you call the air conditioning repair technician. With that in mind, here are some reasons your HVAC system may be failing and what you can do:
Coils and Vents
One of the first things you should check are the coils of and vents of your HVAC unit. These are usually found indoors in the HVAC closet or storage area. Remove the filters from the coils and check the coils themselves. If you see a buildup of dust and debris then this could be an issue causing the HVAC system to no longer cool. The dust and debris can clog the coils and the vents causing them to work harder and finally overheat and shut down. Clean the coils and vents with mild soap and warm water or with a special cleaner you can find at most hardware stores.
Most home HVAC units or air conditioner systems have a thermostat that runs on batteries of some kind. The trick to this is that if the batteries are dead, the thermostat will not work. Though that may seem pretty simple and common enough that people should recognize it as an issue, most don't because they think that the thermostat is connected to electricity and the battery is simply a backup. Check the batteries and the thermostat screen. You may find that it is off or that a small battery icon is showing up in the background. If it is, change the batteries and reset the thermostat.
Check the Condenser and Breaker
If you have checked the coils, vents, and the thermostat you can check one last area. This area is located outside or at the fuse box. It is the condenser and the breaker. Make sure the condenser outside is working. If it is not, you can reset it from the fuse box. Just turn off the breaker, wait a few minutes, and turn it back on. This can help to reset the unit and get it started again.
By testing or troubleshooting these reasons before you call an HVAC repair technician, you can possibly avoid a costly visit. You can also help reduce troubleshooting time so the repair technician can get to the root of the problem faster if you can't figure it out as a DIY.
