6 Common Reasons Why Your Air Conditioner Stopped Working

Hot weather is in full force in Florida, even throughout most of winter, and if you appreciate a cool home, your air conditioner is going to get lots of use. Cooling off is a breeze if your A/C system is working well. Like everything else, air conditioners can break down, and this is even worse when it happens on a hot day. We have listed several reasons why your air conditioner may not be working, as well as how you can remedy the situation.

1. Dead Batteries in Your Thermostat

Your air conditioner may not be having any problems at all; it may be due to dead batteries in your thermostat. Simply replace the batteries if your display screen is blank.
You should also check that your thermostat is set to cool. If it’s not, you are running either the heat or just your fan.

2. Clogged Drain Tube

Most AC units have a float switch. The float switch in your HVAC system is really a water sensor. What it does is give your AC system the ability to recognize if drains are clogged, and if it detects that problem, it shuts the system off immediately.

3. Your Disconnect Switch is Off

The indoor switch may have been bumped and switched off by accident if it is located in the attic or garage. Always ensure that the switch is turned on.
A disconnect switch is also installed next to your outdoor air conditioner unit. The switch may have been turned off for lawn maintenance or other reasons. This is an easy item to reset if need be.

4. The Circuit Breaker was Tripped

Do you have a tripped breaker in your breaker box? Maybe it’s the one that’s connected to your HVAC system. Reset the breaker and retry your air conditioner. It may be because your circuit is overloaded if your breaker keeps tripping.

5. Your Air Filter is Dirty and Needs to be Changed

To allow your equipment to function properly, it’s important to change your air filter on a regular basis. Filters can become blocked with dirt if not changed on a regular basis, leading to restricted airflow.

6. Your Coils Are Dirty

You may have a dirty coil if the air coming out of your vents is not great but your thermostat is set for cool. There are actually two coils in your air conditioner. The first in your outdoor unit and the second in your indoor unit. These coils can become dirty if you do not have regular maintenance performed on your HVAC system. The heat exchangers will not be able to extract heat from your home effectively if they have accumulated a lot of dirt. Basically what happens here is that the air is recirculated at more or less the same temperature, never reaching the desired temperature your thermostat is set on.

All of the problems listed above can be prevented. A regular maintenance schedule can prevent these and many other common problems.. A tune-up and inspection are always advised before a heat cycle or cooling cycle to detect small problems before they translate into larger and more costly repairs.
