Air Conditioner Repair Checklist

1. AC Won’t Turn On

There can be a couple of explanations why your AC equipment won’t work: an overloaded circuit breaker, inaccurate thermostat settings, a switched off switch or an overfull condensate drain pan.

Blown Circuit Breaker

Your air conditioner won’t turn on when you have a tripped breaker.

To determine if one has tripped, find your residence’s main electrical panel. You can find this silver device on the wall in the basement, garage or closet.

  • Ensure your hands and feet aren’t wet before you work on the panel or breakers.
  • Look for the breaker identified “AC” and confirm it’s in the “on” position. If it’s tripped, the switch will be in the "off" position.
  • Steadily move the switch back to the “on” position. If it instantaneously trips again, don’t touch it and call us at 402-509-5940. A fuse that keeps turning off could indicate your residence has an electrical issue.

If your thermostat isn’t signaling your equipment to run, it won’t switch on.

The most important point is ensuring it’s on “cool” and not “heat.” Otherwise your air conditioner may not turn on. You could also receive warm air coming from vents because the heat is going instead.

If you’re using a digital thermostat:

  • Swap out the batteries if the readout is blank. If the readout is presenting garbled letters, get a new thermostat.
  • Ensure the right setting is showing. If you can’t alter it, override it by lowering the temperature and hitting the “hold” button. This will make your AC start if scheduling is incorrect.
  • Attempt to set the thermostat 5 degrees lower than the room’s temperature. Your AC won’t cool if the thermostat is identical to the room’s temperature.

Once your thermostat is calibrated accurately, you should receive cool air quickly.

If you’re using a smart thermostat, including ones manufactured by Nest, Ecobee, Lux, Honeywell or Bosch, go to the manufacturer’s website for help. If you’re still having problems, contact us at 402-509-5940 for support.

Your air conditioner usually has a power-cutting device near its outdoor unit. This device is generally in a metal box mounted on your house. If your unit has recently been fixed, the lever may have accidentally been turned off.

Clogged Condensate Drain Pan drain pan icon

Condensate drain pans hold the surplus condensation your system takes out of the air. This pan can be situated either beneath or within your furnace or air handler.

When there’s a blockage or backed up drain, water can become concentrated and trigger a safety setting to stop your unit.

If your pan includes a PVC pipe or drain, you can clear the extra water with a special pan-cleaning tablet. You can purchase these tabs at a home improvement or hardware shop.

If your pan includes a pump, locate the float switch. If the lever is “up” and there’s liquid in the pan, you could need to get a new pump. Call us at 402-509-5940 for help.

2. AC Blows Warm Air

If your equipment is going but not providing cold air, its airflow may be obstructed. Or it may not have sufficient refrigerant.

Obstructed Airflow

Your equipment’s airflow can be reduced by a clogged air filter or filthy condenser.

How to Put in a New Your Air Filter

A filthy filter can create a lot of troubles, such as:

  • Reduced airflow
  • Frozen refrigerant lines or evaporator coil
  • Intermittent cooling
  • Increased electricity costs
  • Leading your system to break down sooner

We recommend installing new flat filters once a month, and pleated filters every three months.

If you aren’t sure when you last replaced your filter, switch off your equipment fully and take out the filter. You can spot the filter in your furnace or air pump’s blower compartment. It might also be situated in a connected filter box or wall-mounted return air grille.

Tilt the filter up to your light fixture. If you can’t see any light, you certainly should replace it.

How to Clean Your Cooling Unit

Weeds, vegetation and shrubbery can get in the way of your condensing unit. This may limit its airflow, make it less energy efficient and impact your comfort. Here’s a way you can get your unit running smoothly again.

  1. Switch off the electrical current fully at the breaker or external device.
  2. Get rid of plant debris around the equipment. Once you’ve removed bigger debris within a two-foot range, you can use a soft brush or vacuum to gingerly remove dirt from the condenser fins. Kinked fins can also affect performance.
  3. Use a hose nozzle to gingerly take off dirt on the fins from inside the equipment. Don’t get water on the fan motor.
  4. Turn the power back on.

Leaking Refrigerant

When air conditioning units don’t have enough refrigerant, they’ll struggle to remove heat and humidity from your rooms.

Here are a few symptoms that your system is leaking refrigerant:

  1. It takes an extended amount of time to lower the temperature in your rooms and you’re continually decreasing the temperature on the thermostat.
  2. Air conditioning blowing through the ducts isn’t as cold as it should be.
  3. You’re experiencing fizzing or burbling racket when cooling is on.
  4. Your evaporator coil is frozen on account of having an issue handling humidity.

Think your unit is seeping refrigerant? You need a licensed heating and cooling service specialist to repair the leak and refill the right amount of refrigerant in your unit. Reach us at 402-509-5940 for support.

3. AC Not Blowing Enough Air

When it appears like you’re not getting enough cold air, there’s probably a clog or detachment somewhere in your AC system.

  • The first step is checking your air filter. Buy a new one if it’s dirty.
  • Make sure the vents are open across your home.
  • If you’re still not getting ample cold air, you should have your duct system examined by a professional like Interstate Heating & Air Conditioning. Your ducts may need to be repaired or reconnected in difficult locations like your attic, basement or crawl space.
