Air Conditioner Repair Checklist

1. AC Won’t Turn On

There can be a couple of reasons why your air conditioning won’t start: a blown circuit breaker, incorrect thermostat settings, a turned off switch or an overfull condensate drain pan.

Triggered Circuit Breaker

Your air conditioner won’t work when you have an overloaded breaker.

To find out if one has blown, go to your house’s main electrical panel. You can locate this metallic fixture on the wall in the basement, garage or closet.

  • Confirm your hands and feet are free of moisture before you check the panel or breakers.
  • Find the breaker marked “AC” and confirm it’s in the “on” position. If it’s triggered the breaker will be in the middle or “off” position.
  • Steadily move the switch back to the “on” location. If it immediately triggers again, don’t touch it and call us at 405-494-7444. A breaker that keeps flipping might indicate your house has an electrical problem.

Wrong Thermostat Settings

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

The key part is checking it’s switched to “cool” and not “heat.” Otherwise your air conditioner may not switch on. Or you may receive. heated air blowing from vents since the heater is on instead.

If you rely on a traditional thermostat:

  • Swap out the batteries if the readout is empty. If the monitor is presenting jumbled numbers, buy a new thermostat.
  • Check the right option is on the display. If you can’t update it, cancel it by decreasing the temperature and pressing the “hold” button. This will make your AC start if programming is not right.
  • Attempt to set the thermostat 5 degrees colder than the house’s temperature. Your AC won’t start if the thermostat is set the same as the house’s temperature.

Once your thermostat is adjusted correctly, you should begin getting cool air quickly.

If you rely on a smart thermostat, like one made by Nest, Ecobee, Lux, Honeywell or Bosch, check the manufacturer’s website for troubleshooting. If you still can’t get it to work, reach us at 405-494-7444 for help.

Shut-Down Switch

Your system probably has a shut-off switch around its condenser. This switch is generally in a metal box mounted on your residence. If your AC has recently been repaired, the lever may have inadvertently been put in the “off” position.

Blocked Condensate Drain Pan

Condensate drain pans hold the additional water your equipment pulls from the air. This pan is located either below or within your furnace or air handler.

When there’s a clog or backed up drain, water can become concentrated and prompt a safety feature to switch off your equipment.

If your pan has a PVC pipe or drain, you can drain the additional condensation with a formulated pan-cleaning tablet. You can buy these capsules at a home improvement or hardware shop.

If your pan includes a pump, locate the float switch. If the mechanism is “up” and there’s water in the pan, you could need to get a new pump. Reach us at 405-494-7444 for assistance.

2. AC Blows Warm Air

If your system is working but not cooling, its airflow might be obstructed. Or it might not have adequate refrigerant.

Clogged Airflow

Your system’s airflow can be decreased by a plugged air filter or dirty condenser.

How to Replace Your Air Filter

A filthy filter can lead to countless issues, including:

  • Reduced comfort
  • Icy refrigerant lines or evaporator coil
  • Uneven cooling
  • Higher electricity costs
  • Causing your system to break down more quickly

We recommend changing flat filters once a month, and accordion filters every three months.

If you can’t recall when you last replaced yours, turn off your equipment completely and take out the filter. You can find the filter in your furnace or air pump’s blower compartment. It may also be located in a connected filter case or wall-mounted return air grille.

Tilt the filter up to the sunshine. If you can’t see any light you certainly should get a new one.

4 Steps to Cleaning Your Air Conditioning Equipment

Weeds, vegetation and leaves can obstruct your condensing system. This could reduce its airflow, lower its energy efficiency and change your comfort. Here’s a method you can follow to get your equipment operating smoothly again.

  1. Switch off electricity fully at the breaker or outdoor device.
  2. Remove plant waste around the unit. Once you’ve cleared larger clutter within a two-foot area, you can use a fine-bristled brush or vacuum to gingerly remove dust from the equipment’s fins. Bent fins can also hurt effectiveness, so you can attempt to reshape them with a blunt knife.
  3. Use a hose nozzle to carefully clean the fins from inside the unit. Don’t get water on the fan motor.
  4. Put the top back on and turn on the power.

Insufficient Refrigerant

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

Here are several symptoms that your system is leaking refrigerant:

  1. It takes too long to refresh your residence and you’re continually lowering the thermostat.
  2. Air conditioning blowing through the vents isn’t as chilly as it should be.
  3. You’re noticing hissing or bubbling noises when the AC is on.
  4. Your evaporator coil is icy because it’s having difficulty handling heat.

Think your system is leaking refrigerant? You need a qualified heating and cooling service specialist to repair the leak and replenish the proper measurement of refrigerant in your equipment. Contact us at 405-494-7444 for support.

3. AC Not Blowing Enough Air

When it feels like you’re not having adequate amounts of chilled air, there’s usually a blockage or disconnection inside your AC system.

  • The beginning step is examining your air filter. Buy a new one if it’s dirty.
  • Then check the ductwork is clear across your house.
  • If you’re still not experiencing enough chilled air, you should have your ducts inspected by a professional like Comfort Concepts Heating & Air Conditioning. Your ducts may need to be repaired or rejoined in limited space locations like your attic, basement or crawl space.
