Air Conditioner Repair Checklist
1. AC Won’t Turn On
There can be a few reasons why your air conditioning won’t start: a triggered circuit breaker, inaccurate thermostat settings, a switched off switch or an overflowing condensate drain pan.
Overloaded Circuit Breaker
Your air conditioning won’t work when you have a blown breaker.
To check if one has gotten overloaded, find your home’s main electrical panel. You can find this silver fixture on the wall in the basement, garage or closet.
- Make sure your hands and feet aren’t wet before you touch the panel or breakers.
- Locate the breaker identified “AC” and make sure it’s in the “on” spot. If it’s tripped, the switch will be in the "off" position.
- Steadily transfer the switch back to the “on” location. If it instantaneously flips again, don’t touch it and get in touch with us at 715-318-6728. A breaker that keeps flipping might mean your house has an electrical problem.
Wrong Thermostat Settings
If your thermostat isn’t telling your system to work, it won’t activate.
The main point is making sure it’s on “cool” and not “heat.” Otherwise your air conditioning might not switch on. You might also have hot air coming from vents since the furnace is running instead.
If you have a traditional thermostat:
- Replace the batteries if the monitor is blank. If the monitor is presenting jumbled letters, buy a new thermostat.
- Ensure the correct mode is on the display. If you can’t change it, override it by decreasing the temperature and hitting the “hold” button. This will make your AC start if scheduling is wrong.
- Attempt to set the thermostat 5 degrees below the house’s temperature. Your AC won’t work if the thermostat is set the same as the room’s temperature.
Once your thermostat is set accurately, you should receive chilled air promptly.
If you’re using a smart thermostat, like one manufactured by Nest, Ecobee, Lux, Honeywell or Bosch, check the manufacturer’s website for troubleshooting. If you still can’t get it to work, contact us at 715-318-6728 for support.
Your cooling equipment typically has a shut-down device by its condenser. This switch is generally in a metal box mounted on your residence. If your air conditioner has recently been maintained, the device may have inadvertently been turned off.
Blocked Condensate Drain Pan
Condensate drain pans catch the additional liquid your air conditioner removes from the air. This pan can be found either beneath or within your furnace or air handler.
When there’s a blockage or clogged drain, water can accumulate and trigger a safety feature to stop your air conditioner.
If your pan includes a PVC pipe or drain, you can drain the extra water with a special pan-cleaning tablet. You can get these capsules at a home improvement or hardware store.
If your pan includes a pump, locate the float switch. If the mechanism is “up” and there’s liquid in the pan, you could need to install a new pump. Reach us at 715-318-6728 for support.
2. AC Blows Warm Air
If your system is going but not cooling, its airflow may be congested. Or it might not have enough refrigerant.
Your system’s airflow can be reduced by a blocked air filter or dusty condenser.
How to Replace Your Air Filter
A dusty filter can cause countless troubles, including:
- Reduced cooling
- Icy refrigerant lines or evaporator coil
- Intermittent cooling
- Larger energy bills
- Making your system wear out faster
We recommend 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 unit completely and pull out the filter. You can spot the filter in your furnace or air pump’s blower compartment. It might also be situated in an adjoining filter box or wall-mounted return air grille.
Hold the filter up to your light fixture. If you see a lot of dust, you certainly should get a new one.
4 Tips on Cleaning Your Cooling System
Greenery, grass and leaves can get in the way of your condensing system. This could reduce its airflow, make it less energy efficient and affect your comfort. Here’s how you can get your system operating smoothly again.
- Turn off the electrical current totally at the breaker or outdoor device.
- Remove yard debris around the AC. Once you’ve removed all the clutter within a two-foot area, you can use a soft brush or vacuum to slowly remove dust from the equipment’s fins. Crooked fins can also impact effectiveness.
- Use a hose nozzle to slowly remove gunk off the fins from inside the system. Make sure to avoid getting liquid on the fan motor.
- Restore the power.
Low Refrigerant Levels
When cooling systems don’t have ample refrigerant, they’ll have difficulty removing heat and humidity from your house.
Here are a few signs that your system is losing refrigerant:
- It takes too long to lower the temperature in your residence and you’re continually turning down the thermostat.
- Air blowing through the ducts isn’t as chilly as it should be.
- You’re noticing hissing or burbling sounds when the AC runs.
- Your evaporator coil is frosty on account of having an issue taking on warmth.
Think your unit is seeping refrigerant? You need a licensed heating and cooling service specialist to fix the leak and replenish the proper amount of refrigerant in your system. Contact us at 715-318-6728 for help.
3. AC Not Blowing Enough Air
When it seems like you’re not having enough cool air, there’s possibly an obstruction or detachment within your air conditioning system.
- The beginning place is checking your air filter. Buy a new one if it’s dusty.
- Make sure the vents are open around your house.
- If you’re still not getting adequate chilled air, you should have your ducts inspected by a specialist like Walter's-Eaton's Electric, Plumbing, Heating & AC. Your ducts could need to be serviced or rejoined in limited space areas like your attic, basement or crawl space.
