Air Conditioner Repair Checklist

1. AC Won’t Turn On

There can be a few reasons why your air conditioning won’t run: an overloaded circuit breaker, incorrect thermostat settings, a shut off switch or a full condensate drain pan.

Triggered Circuit Breaker

Your AC won’t start when you have a tripped breaker.

To find out if one has tripped, locate your residence’s main electrical panel. You can spot this metallic box on the wall in the basement, garage or closet.

  • Ensure your hands and feet are dry before you touch 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 "off" position.
  • Steadily shift the lever back to the “on” position. If it instantly trips again, leave it alone and get in touch with us at 608-291-3606. A breaker that keeps flipping may signal your house has an electrical problem.

If your thermostat isn’t telling your system to work, it won’t switch on.

The first step is making sure it’s switched to “cool” and not “heat.” Otherwise your air conditioner might not start running. You may also get hot air moving from vents because the heater is running instead.

If you rely on a traditional thermostat:

  • Put in new batteries if the monitor is clear. If the readout is showing jumbled characters, get a new thermostat.
  • Make sure the right program is showing. If you can’t alter it, override it by dropping the temperature and pressing the “hold” button. This will cause your AC to run if programming is wrong.
  • Attempt to set the thermostat 5 degrees lower than the space’s temperature. Your AC won’t start if the thermostat is identical to the room’s temperature.

Once your thermostat is set accurately, you should receive cold air fast.

If you’re using a smart thermostat, including ones made by Nest, Ecobee, Lux, Honeywell or Bosch, go to the manufacturer’s website for assistance. If it still won’t work, contact us at 608-291-3606 for support.

switch icon Turn-Off Switch

Your air conditioner usually has a shut-down device near its outdoor unit. This device is typically in a metal box mounted on your house. If your unit has recently been serviced, the device may have inadvertently been turned off.

Clogged Condensate Drain Pan drain pan icon

Condensate drain pans keep the surplus liquid your system takes out of the air. This pan can be positioned either under or inside your furnace or air handler.

When there’s a blockage or clogged drain, water can accumulate and initiate a safety control to turn off your system.

If your pan includes a PVC pipe or drain, you can clear the extra liquid with a custom pan-cleaning tab. You can buy these tabs at a home improvement or hardware store.

If your pan includes a pump, find the float switch. If the switch is “up” and there’s liquid in the pan, you could need to install a new pump. Contact us at 608-291-3606 for assistance.

2. AC Blows Warm Air

If your equipment is working but not providing cold air, its airflow may be blocked. Or it may not have adequate refrigerant.

Clogged Airflow

Your unit’s airflow can be restricted by a blocked air filter or dusty condenser.

How to Change Your Air Filter

A dusty filter can cause many problems, like:

  • Limited cooling
  • Frosted refrigerant lines or evaporator coil
  • Inconsistent cooling
  • Increased electricity costs
  • Leading your system to break down sooner

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

If you can’t remember when you last replaced your filter, shut off your equipment completely and remove the filter. You can locate the filter in your furnace or air pump’s blower compartment. It may also be found in a connected filter case or wall-mounted return air grille.

Hold the filter up to your light fixture. If you can’t see any light, you should get a new one.

4 Tips on Cleaning Your Cooling Equipment

Brush, vegetation and shrubbery can block your condensing equipment. This could limit its airflow, make it less energy efficient and impact your comfort. Here’s how you can get your unit running properly again.

  1. Turn off electricity totally at the breaker or external lever.
  2. Clear plant waste around the AC. Once you’ve gotten rid of bigger refuse within a two-foot area, you can use a paint brush or vacuum to slowly remove dust from the condenser fins. Distorted fins can also impact capability.
  3. Use a hose nozzle to carefully remove gunk off the fins from inside the equipment. Be careful to avoid getting water on the fan motor.
  4. Turn the power back on.

Not Enough Refrigerant

When cooling equipment doesn’t have enough refrigerant, they’ll have to work much harder to remove heat and humidity from the air.

Here are a few flags that your unit is seeping refrigerant:

  1. It takes an extended amount of time to refresh your residence and you’re continually lowering the thermostat.
  2. Cooling moving through the ducts isn’t as cold as it should be.
  3. You’re noticing whistling or gurgling racket when the air conditioning runs.
  4. Your evaporator coil is icy because it’s having trouble absorbing warmth.

Think your system is seeping refrigerant? You need a licensed heating and cooling service professional to repair the leak and restore the correct amount of refrigerant in your equipment. Call us at 608-291-3606 for support.

3. AC Not Blowing Enough Air

When it feels like you’re not receiving adequate amounts of cool air, there’s possibly a blockage or detachment inside your air conditioning system.

  • The first stage is looking at your air filter. Buy a new one if it’s dirty.
  • Make sure the vents are open throughout your rooms.
  • If you’re still not getting ample chilled air, you should have your ductwork examined by a professional like Lanz Furnace and Fireplace. Your ducts may need to be repaired or hooked up again in limited space areas like your attic, basement or crawl space.
