1. AC Won’t Turn On
There are a few reasons why your central air conditioning system isn’t running, like a switch turned to the wrong setting, a blown circuit, incorrect thermostat settings or a condensate pan that needs to be drained.
Blown Circuit Breaker
The AC won’t come on if you have a tripped breaker.
To find out if the breaker’s tripped, head to the house’s main electrical panel. It’s a gray metal box mounted to the wall, usually in a basement, garage, or closet.
- Don’t forget to make sure your hands and feet are dry before touching the panel or breakers.
- Find the one labeled “AC” and double-check that it’s in the “on” position. If not, the breaker will be in the middle or “off” position. That’s what it means to have a tripped breaker.
- To fix this, shift the breaker back to the “on” position. If it trips again, leave it alone and give us a call at 469-505-0525, because a breaker that is repeatedly tripping could mean an electrical problem.
Incorrect Thermostat Settings
If the thermostat isn’t signaling your AC to run, it won’t be able to turn on.
The first and most important step is to make sure it’s not set to “heat.”
If you’re using a digital thermostat:
- Put in new batteries if the screen is dark. If the symbols are incorrect or scrambled, the thermostat will need to be replaced.
- Make sure it’s set to the correct program. Override it by lowering the temperature and pressing “hold” if you can’t change the program. This will force the AC to start if the programming is incorrect.
- Set the thermostat to a temperature that’s cooler than the room’s temperature. If it’s the same temperature, the AC won’t start.
Once the thermostat is on the correct settings, the cool air should start flowing very quickly.
If you’re using a smart thermostat like Nest, Ecobee, Lux, Honeywell or Bosch, take a look at the manufacturer’s website. If you’re still having trouble, give us a call at 469-505-0525 and see why our service is 100% guaranteed.
Turned Off Switch
The AC most likely has a shutoff switch near the outside unit. This switch is usually inside a metal box mounted to the outside of your home. If that unit has been recently repaired or maintained, the switch may still be set to the “off” position, and will need to be switched back.
Clogged Condensate Drain Pan
The drain pans collect the excess moisture your system removes from the air. It’s located either under or inside your furnace or air handler.
If there’s a blockage or clog, water can build pressure and trigger a safety feature. This will turn off the system.
If the pan has PVC pipe or drains, clear the excess water with a special cleaning tablet. You can find these tablets at home improvement or hardware stores.
If the pan has a pump, you’ll need to find the float switch. If the switch is set to “up” and liquid has collected in the pan, the pump might need to be replaced. Call us at 469-505-0525 and let us help you make things right.
2. AC Blows Warm Air
If you’re getting warm air, the airflow could be blocked. Or there might not be enough refrigerant to properly cool the air.
Your AC system’s airflow could be affected by a dirty condenser, or more commonly, a clogged filter.
How to Change Your Air Filter
A bad filter can cause lots of problems like:
- Reduced airflow
- Frozen refrigerant lines or evaporator coil
- Uneven cooling
- Increased energy bills
- Premature system failure
It’s recommended to change flat filters once a month, and pleated filters every three months.
If you can’t remember the last time you changed the filter, turn the system off completely and remove the filter. You can find it in your furnace or air handler’s blower compartment, or in an attached filter case or wall-mounted return air grille.
Once you remove it, hold the filter up to the light. If you can’t see through it, it’s time to replace the filter.
How to Clean Your Air Conditioning System
Lots of small debris could block your condensing unit, which limits its airflow and energy efficiency. To get it running smoothly again:
- Turn the breaker or outdoor switch off.
- Remove all yard waste that has accumulated around the AC in a two-foot radius.
- You can then use a brush or vacuum to clean off the condenser fins. Energy efficiency can be affected by bent fins, so carefully try to reshape them.
- Remove the top of the AC and any yard waste that has collected inside. Then wipe down the condenser fan with a damp (not wet) cloth.
- Use your hose to clean the fins from inside the unit. Be careful not to get water on the fan motor.
- After you replace the top, restore the power.
When your unit doesn’t have enough refrigerant, it’s much harder to remove heat and humidity from a room.
There are a couple of ways to figure out if your system is leaking:
- It takes too long to cool your home, and you’re constantly turning down the thermostat.
- The air that’s blowing is not as cool as it’s supposed to be.
- There are hissing or gurgling sounds coming from the AC when it runs.
- The evaporator coil has frozen since it can’t absorb heat.
If you think your AC is leaking refrigerant, you’ll need a licensed professional to find the leak and add the correct amount of refrigerant to your system. Call us at 469-505-0525 for help. Our technicians are “Grandma-certified”: you’ll see that we treat all our customers like family.
3. AC Not Blowing Enough Air
Sometimes your AC will run but won’t blow enough air. This could mean there’s a blockage or disconnection hiding somewhere in your system or ductwork. Some tips to find this problem are:
- Start with the air filter. Replace it if it’s dirty.
- Make sure all registers are open throughout the house.
- If there’s still not enough air coming through, the ductwork may need servicing. This could be difficult if it’s in an area like the attic or crawl space, so depend on the professionals at Diamond Blue Air for help. Call us at 469-505-0525.
Should You Replace Your AC Instead?
While you can’t predict exactly when your AC system might stop working, there are a few common signs that could indicate it needs to be replaced rather than repaired.
