Air Conditioner Repair Checklist

1. AC Won’t Turn On

There can be several causes why your central AC system won’t start: an overloaded circuit breaker, wrong thermostat settings, a switched off switch or an overflowing condensate drain pan.

Overloaded Circuit Breaker

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

To see if one has gotten overloaded, go to your home’s main electrical panel. You can locate this silver device on the wall in the basement, garage or closet.

  • Confirm your hands and feet aren’t wet before you work on the panel or breakers.
  • Look for the breaker marked “AC” and ensure it’s in the “on” position. If it’s overloaded, the breaker will be in the "off" position.
  • Firmly transfer the lever back to the “on” position. If it instantaneously flips again, don’t touch it and contact us at 256-801-4701. A fuse that keeps flipping might signal your house has an electrical issue.

If your thermostat isn’t signaling your AC to start, it won’t switch on.

The main step is ensuring it’s switched to “cool” and not “heat.” Otherwise your AC may not turn on. You may also get heated air coming from vents because the heater is on instead.

If you’re using a digital thermostat:

  • Replace the batteries if the screen is empty. If the screen is displaying scrambled characters, replace the thermostat.
  • Make sure the right program is showing. If you can’t update it, override it by decreasing the temperature and pressing the “hold” button. This will make your AC start if the configuration is incorrect.
  • Test setting the thermostat 5 degrees lower than the room’s temperature. Your AC won’t work if the thermostat matches the room’s temperature.

Once your thermostat is set correctly, you should receive cool air promptly.

If you rely on a smart thermostat, such as one made by Nest, Ecobee, Lux, Honeywell or Bosch, check the manufacturer’s website for troubleshooting. If you’re still having problems, contact us at 256-801-4701 for help.

switch icon Shut-Off Switch

Your AC typically has a power-cutting switch near its outdoor unit. This lever is typically in a metal box attached to your home. If your AC has recently been serviced, the lever may have accidentally been turned off.

Overflowing Condensate Drain Pan drain pan icon

Condensate drain pans catch the additional condensation your air conditioner removes from the air. This pan is located either below or within your furnace or air handler.

When there’s an obstruction or blocked drain, water can build up and initiate a safety setting to turn off your equipment.

If your pan includes a PVC pipe or drain, you can get rid of the surplus liquid with a formulated pan-cleaning capsule. You can get these capsules at a home improvement or hardware retailer.

If your pan involves a pump, locate the float switch. If the mechanism is “up” and there’s liquid in the pan, you could need to get a new pump. Reach us at 256-801-4701 for help.

2. AC Blows Warm Air

If your air conditioner is going but not delivering cold air, its airflow could be obstructed. Or it might not have sufficient refrigerant.

Obstructed Airflow

Your system’s airflow can be restricted by a plugged air filter or dusty condenser.

How to Replace Your Air Filter

A dirty filter can create a lot of problems, including:

  • Limited cooling
  • Icy refrigerant lines or evaporator coil
  • Uneven cooling
  • Higher electricity costs
  • Leading your system to break down faster

We suggest replacing flat filters every four weeks, and pleated filters every three months.

If you can’t recall when you last replaced your filter, turn off your AC completely and take out the filter. You can locate the filter in your furnace or air pump’s blower compartment. It could also be located in an attached filter holder or wall-mounted return air grille.

Angle the filter up to the sunshine. If you see a lot of dust, you should replace it.

How to Clean Your Cooling Equipment

Brush, plants and leaves can obstruct your condensing equipment. This may reduce its airflow, make it less energy efficient and impact your comfort. Here’s a way you can get your system working well again.

  1. Turn off the electrical current completely at the breaker or outside device.
  2. Remove greenery rubbish around the AC. Once you’ve removed all the refuse within a two-foot radius, you can use a fine-bristled brush or vacuum to carefully remove dirt from the unit’s fins. Warped fins can also affect capability.
  3. Use a hose nozzle to slowly remove gunk off the fins from inside the system. Don’t get water on the fan motor.
  4. Restore the power.
refrigerant icon

Insufficient Refrigerant

When cooling systems don’t have sufficient refrigerant, they’ll struggle to remove heat and humidity from your house.

Here are several flags that your equipment is leaking refrigerant:

  1. It takes a long time to lower the temperature in your rooms and you’re regularly lowering the thermostat.
  2. Cooling blowing through the registers isn’t as cold as it should be.
  3. You’re noticing hissing or bubbling noises when the air conditioning is on.
  4. Your evaporator coil is iced over on account of having an issue taking on warmth.

Worried your equipment is losing refrigerant? You need a licensed heating and cooling service specialist to fix the leak and restore the right level of refrigerant in your system. Reach us at 256-801-4701 for help.

3. AC Not Blowing Enough Air

When it seems like you’re not receiving adequate amounts of cool air, there’s possibly a clog or disconnection somewhere in your air conditioning system.

  • The beginning place is examining your air filter. Replace it if it’s soiled.
  • Make sure the vents are open throughout your residence.
  • If you’re still not receiving adequate chilled air, you should have your ductwork inspected by a specialist like All Weather Heating & Air Conditioning Inc. Your ducts might need to be repaired or reconnected in tricky locations like your attic, basement or crawl space.
