Air Conditioner Repair Checklist

1. AC Won’t Turn On

There can be a few explanations why your air conditioning system won’t work: a blown circuit breaker, inaccurate thermostat settings, a switched off switch or a full condensate drain pan.

Tripped Circuit Breaker

Your air conditioning won’t start when you have a blown breaker.

To see if one has blown, find your residence’s main electrical panel. You can locate this metallic device on the wall in the basement, garage or closet.

  • Make sure your hands and feet are free of moisture before you check the panel or breakers.
  • Find the breaker identified “AC” and confirm it’s in the “on” position. If it’s tripped the switch will be in the middle of the panel or “off” spot.
  • Firmly transfer the breaker back to the “on” spot. If it instantaneously trips again, leave it alone and reach us at 402-509-5940. A fuse that keeps turning off may signal your home has an electrical problem.

Incorrect Thermostat Settings

If your thermostat isn’t telling your AC to start, it won’t activate.

The most important point is making sure it’s on “cool” and not “heat.” Otherwise your AC may not switch on. Or you might get. hot air coming from vents being the heater is running instead.

If you’re using a digital thermostat:

  • Swap out the batteries if the screen is empty. If the readout is showing garbled characters, get a new thermostat.
  • Check the proper mode is on the display. If you can’t update it, cancel it by dropping the temperature and hitting the “hold” button. This will force your AC to work if the configuration is wrong.
  • Try setting the thermostat 5 degrees below the house’s temperature. Your AC won’t work if the thermostat matches the room’s temperature.

Once your thermostat is calibrated properly, you should start getting refreshing air quickly.

If you rely on a smart thermostat, such as one manufactured by Nest, Ecobee, Lux, Honeywell or Bosch, look at the manufacturer’s website for help. If it still won’t work, reach us at 402-509-5940 for help.

Shut-Down Switch

Your system probably has a power-cutting lever around its outside unit. This lever is typically in a metal box hung on your residence. If your equipment has recently been fixed, the switch may have accidentally been left in the “off” position.

Blocked Condensate Drain Pan

Condensate drain pans catch the surplus liquid your air conditioner takes out of the air. This pan can be situated either below or within your furnace or air handler.

When there’s a blockage or blocked drain, water can build up and trigger a safety feature to switch off your system.

If your pan involves a PVC pipe or drain, you can drain the extra water with a special pan-cleaning tab. You can buy these capsules at a home improvement or hardware retailer.

If your pan includes a pump, look for the float switch. If the mechanism is “up” and there’s water in the pan, you may need to replace the pump. Reach us at 402-509-5940 for support.

2. AC Blows Warm Air

If your air conditioner is going but not cooling, its airflow may be congested. Or it could not have enough refrigerant.

Obstructed Airflow

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

How to Replace Your Air Filter

A dusty filter can create a lot of problems, such as:

  • Reduced comfort
  • Frosted refrigerant lines or evaporator coil
  • Inconsistent cooling
  • Bigger cooling bills
  • Causing your system to break down more quickly

We propose installing new flat filters every four weeks, and accordion filters every three months.

If you aren’t sure when you last installed a new one, turn off your AC completely and take out the filter. You can find the filter in your furnace or air pump’s blower compartment. It may also be found in an attached filter box or wall-mounted return air grille.

Hold the filter up to the sunshine. If you can’t see any light you should buy a new filter.

4 Tips on Cleaning Your AC System

Brush, plants and sticks can block your condensing unit. This could restrict its airflow, impact its energy efficiency and change your comfort. Here’s a way you can get your system running smoothly again.

  1. Shut off electricity completely at the breaker or outdoor lever.
  2. Remove vegetation rubbish around the unit. Once you’ve gotten rid of all the refuse within a two-foot radius, you can use a paint brush or vacuum to slowly clean the condenser fins. Distorted fins can also affect capability, so you can attempt to adjust them with a small knife.
  3. Use a hose nozzle to slowly remove gunk off the fins from inside the system. Be careful to avoid getting moisture on the fan motor.
  4. Replace the top and turn the power back on.

Low Refrigerant Levels

When air conditioning units don’t have adequate refrigerant, they’ll have difficulty removing heat and humidity from your rooms.

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

  1. It takes a long time to lower the temperature in your house and you’re regularly decreasing the temperature on the thermostat.
  2. Cooling moving through the ducts isn’t as chilly as it should be.
  3. You’re hearing fizzing or gurgling sounds when cooling works.
  4. Your evaporator coil is frozen as a result of having trouble taking on humidity.

Suspect your system is leaking refrigerant? You need a qualified heating and cooling service expert to repair the leak and restore the correct measurement of refrigerant in your unit. Contact us at 402-509-5940 for support.

3. AC Not Blowing Enough Air

When it seems like you’re not having enough cold air, there’s possibly an obstruction or separation somewhere in your air conditioning unit.

  • The beginning step is looking at your air filter. Replace it if it’s filthy.
  • Then check the vents are clear throughout your rooms.
  • If you’re still not getting enough chilled air, you should have your ductwork checked by a expert like Interstate Heating & Air Conditioning. Your duct system could need to be repaired or reconnected in tricky locations like your attic, basement or crawl space.
