1. AC Won’t Turn On

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

Tripped Circuit Breaker

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

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

  • Make sure your hands and feet aren’t wet before you work on the panel or breakers.
  • Find the breaker marked “AC” and ensure it’s in the “on” position. If it’s triggered, the switch will be in the middle or “off” location.
  • Steadily move the switch back to the “on” spot. If it immediately flips again, don’t touch it and call us at 515-344-3579. A breaker that keeps turning off could signal your home has an electrical problem.

incorrect thermostat icon Inaccurate Thermostat Settings

If your thermostat isn’t giving a sign to your equipment to run, it won’t activate.

The most important part is ensuring it’s set to “cool” and not “heat.” Otherwise your air conditioner may not switch on. Or you could receive warm air blowing from vents because the furnace is on instead.

If you’re using a traditional thermostat:

  • Swap out the batteries if the screen is clear. If the monitor is displaying garbled numbers, get a new thermostat.
  • Make sure the correct option 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 not right.
  • Test setting the thermostat 5 degrees cooler than the room’s temperature. Your AC won’t work if the thermostat matches the space’s temperature.

Once your thermostat is set correctly, you should begin getting refreshing air fast.

If you’re using a smart thermostat, including ones manufactured by Nest, Ecobee, Lux, Honeywell or Bosch, check the manufacturer’s website for assistance. If you’re still having problems, reach us at 515-344-3579 for support.

switch icon Shut-Down Switch

Your AC usually has a shut-down lever near its condenser. This lever is generally in a metal box mounted on your house. If your AC has recently been tuned up, the device may have inadvertently been placed in the “off” setting.

Overflowing Condensate Drain Pan drain pan icon

Condensate drain pans catch the additional water your equipment removes from the air. This pan can be situated either below or within your furnace or air handler.

When there’s a clog or backed up drain, water can build up and prompt a safety control to turn off your system.

If your pan involves a PVC pipe or drain, you can drain the surplus liquid with a custom pan-cleaning tab. You can get these tablets at a home improvement or hardware shop.

If your pan has a pump, locate the float switch. If the lever is “up” and there’s moisture in the pan, you might have to get a new pump. Reach us at 515-344-3579 for help.

2. AC Blows Warm Air

If your AC is working but not delivering cold air, its airflow may be obstructed. Or it may not have sufficient refrigerant.

Obstructed Airflow

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

How to Change Your Air Filter

A filthy filter can lead to a lot of troubles, like:

  • Limited comfort
  • Frosted refrigerant lines or evaporator coil
  • Uneven cooling
  • Increased electricity bills
  • Making your system break down more quickly

We propose replacing flat filters every four weeks, and creased filters every three months.

If you can’t recall when you last replaced yours, switch off your system totally and pull out the filter. You can locate the filter in your furnace or air pump’s blower compartment. It might also be located in a connected filter case or wall-mounted return air grille.

Tilt the filter up to the sunshine. If you see a lot of dust, you need to get a new one.

5 Tips on Cleaning Your AC Equipment

Weeds, vegetation and bushes can get in the way of your condensing unit. This may restrict its airflow, make it less energy efficient and change your comfort. Here’s a way you can get your unit operating smoothly again.

  1. Turn off electricity totally at the breaker or outdoor switch.
  2. Remove vegetation rubbish around the unit. Once you’ve gotten rid of bigger clutter within a two-foot range, you can use a paint brush or vacuum to slowly remove dust from the unit’s fins. Distorted fins can also impact performance, so you can attempt to correct them with a dinner knife.
  3. Take off the upper part of your air conditioner and pull out any leaves or sticks that has collected. Then wipe off the condenser fan with a damp scrap cloth.
  4. Use a hose nozzle to slowly clean the fins from inside the system. Make sure to avoid getting liquid on the fan motor.
  5. Put the top back on and restore the power.

Leaking Refrigerant

When cooling systems don’t have ample refrigerant, they’ll have to work much harder to remove heat and humidity from your rooms.

Here are several signs that your system is seeping refrigerant:

  1. It takes a long time to refresh your space and you’re regularly turning down the thermostat.
  2. Cooling coming through the ducts isn’t as chilled as it should be.
  3. You’re hearing fizzing or bubbling noises when the AC is on.
  4. Your evaporator coil is frosted as a result of having difficulty handling heat.

Worried your unit is seeping refrigerant? You need a qualified heating and cooling service professional to repair the leak and refill the correct level of refrigerant in your unit. Reach us at 515-344-3579 for support.

3. AC Not Blowing Enough Air

When it feels like you’re not getting enough cold air, there’s usually a blockage or separation somewhere in your AC equipment.

  • The initial step is examining your air filter. Replace it if it’s dirty.
  • Then check the vents are open around your house.
  • If you’re still not getting sufficient chilled air, you should have your duct system examined by a professional like Heartland Heating & Cooling. Your ductwork could need to be serviced or hooked up again in tricky locations like your attic, basement or crawl space.
