1. AC Won’t Turn On
There can be several causes why your air conditioning system won’t run: a blown circuit breaker, wrong thermostat settings, a turned off switch or an overfull condensate drain pan.
Triggered Circuit Breaker
Your AC won’t work when you have an overloaded breaker.
To determine if one has tripped, locate your residence’s main electrical panel. You can spot this gray box on the wall in the basement, garage or closet.
- Make sure your hands and feet are dry before you touch the panel or breakers.
- Look for the breaker marked “AC” and confirm it’s in the “on” location. If it’s tripped, the breaker will be in the middle of the panel or “off” position.
- Firmly move the switch back to the “on” spot. If it immediately triggers again, don’t touch it and reach us at 515-207-6569. A switch that keeps turning off may mean your house has an electrical issue.
Incorrect Thermostat Settings
If your thermostat isn’t signaling your system to start, it won’t activate.
The key point is ensuring it’s set to “cool” and not “heat.” Otherwise your air conditioner may not turn on. Or you could get heated air moving from vents since the heat is running instead.
If you rely on a regular thermostat:
- Swap out the batteries if the screen is clear. If the monitor is showing jumbled numbers, buy a new thermostat.
- Make sure the right program is displaying. If you can’t change it, cancel it by lowering the temperature and pushing the “hold” button. This will make your AC start if programming is wrong.
- Attempt to set the thermostat 5 degrees cooler than the room’s temperature. Your AC won’t cool if the thermostat is set the same as the room’s temperature.
Once your thermostat is adjusted properly, you should receive chilled air fast.
If you have a smart thermostat, such as one manufactured by Nest, Ecobee, Lux, Honeywell or Bosch, look at the manufacturer’s website for troubleshooting. If you still can’t get it to work, reach us at 515-207-6569 for help.
Shut-Off Switch
Your air conditioner probably has a shut-down lever around its condenser. This switch is commonly in a metal box hung on your home. If your equipment has recently been repaired, the lever may have inadvertently been placed in the “off” location.
Blocked Condensate Drain Pan 
Condensate drain pans keep the extra condensation your system pulls from the air. This pan can be situated either beneath or within your furnace or air handler.
When there’s a blockage or blocked drain, water can build up and trigger a safety control to turn off your air conditioner.
If your pan involves a PVC pipe or drain, you can clear the extra condensation with a formulated pan-cleaning capsule. You can buy these tabs at a home improvement or hardware shop.
If your pan has a pump, find the float switch. If the lever is “up” and there’s water in the pan, you could need to get a new pump. Contact us at 515-207-6569 for support.
2. AC Blows Warm Air
If your equipment is going but not delivering cold air, its airflow may be blocked. Or it could not have adequate refrigerant.
Blocked Airflow
Your system’s airflow can be restricted by a clogged air filter or dirty condenser.
How to Put in a New Your Air Filter
A filthy filter can cause a lot of troubles, including:
- Reduced comfort
- Frozen refrigerant lines or evaporator coil
- Inconsistent cooling
- Increased energy bills
- Making your system break down faster
We suggest installing new flat filters monthly, and pleated filters every three months.
If you aren’t sure when you last installed a new one, switch off your unit completely and pull out the filter. You can find the filter in your furnace or air pump’s blower compartment. It could also be situated in an adjoining filter holder or wall-mounted return air grille.
Tilt the filter up to your light fixture. If you can’t see any light, you should replace it.
Not Enough Refrigerant
When cooling units don’t have enough refrigerant, they’ll have difficulty removing heat and humidity from your home.
Here are a couple of flags that your system is seeping refrigerant:
- It takes an extended amount of time to lower the temperature in your home and you’re constantly decreasing the temperature on the thermostat.
- Cooling coming through the vents isn’t as cold as it should be.
- You’re experiencing whistling or burbling racket when the AC runs.
- Your evaporator coil is frosty on account of having difficulty taking on warmth.
Think your equipment is leaking refrigerant? You need a authorized heating and cooling service specialist to take care of the leak and restore the correct measurement of refrigerant in your equipment. Get in touch with us at 515-207-6569 for support.
3. AC Not Blowing Enough Air
When it appears like you’re not having enough chilled air, there’s potentially a clog or disconnection inside your cooling equipment.
- The first place is checking your air filter. Get a new one if it’s filthy.
- Then make sure the registers are open across your residence.
- If you’re still not experiencing sufficient chilled air, you should have your ducts examined by a pro like Kohles & Bach Heating & Cooling. Your ducts could need to be fixed or reconnected in tricky areas like your attic, basement or crawl space.
