Air Conditioner Repair Checklist
1. AC Won’t Turn On
There can be several explanations why your air conditioning system won’t start: an overloaded circuit breaker, wrong thermostat settings, a turned off switch or a full condensate drain pan.
Tripped Circuit Breaker
Your air conditioning won’t work when you have a blown breaker.
To check if one has blown, find your house’s main electrical panel. You can find this silver device 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 labeled “AC” and make sure it’s in the “on” position. If it’s tripped, the lever will be in the in between or “off” location.
- Steadily shift the switch back to the “on” spot. If it instantaneously triggers again, don’t reset it and get in touch with us at 704-233-7363. A fuse that keeps tripping might signal your residence has electrical trouble.
Incorrect Thermostat Settings
If your thermostat isn’t giving a sign to your equipment to start, it won’t turn on.
The most important point is checking it’s on “cool” and not “heat.” Otherwise your air conditioning will probably not switch on. Or you could have warm air blowing from vents being the heat is going instead.
If you have a traditional thermostat:
- Swap out the batteries if the monitor is empty. If the readout is presenting jumbled characters, get a new thermostat.
- Check the right setting is on the display. If you can’t change it, override it by lowering the temperature and pressing the “hold” button. This will force your AC to work if programming is incorrect.
- Try setting the thermostat 5 degrees colder than the house’s temperature. Your AC won’t cool if the thermostat is set the same as the room’s temperature.
Once your thermostat is adjusted accurately, you should begin getting refreshing air quickly.
If you have a smart thermostat, including ones made by Nest, Ecobee, Lux, Honeywell or Bosch, look at the manufacturer’s website for assistance. If it still won’t work, reach us at 704-233-7363 for help.
Your AC probably has a power-cutting device by its outside unit. This switch is typically in a metal box mounted on your home. If your air conditioner has recently been serviced, the device may have accidentally been positioned in the “off” location.
Blocked Condensate Drain Pan
Condensate drain pans hold the extra water your AC removes from the air. This pan can be found either beneath or in your furnace or air handler.
When there’s a clog or backed up drain, water can build up and initiate a safety control to switch off your system.
If your pan has a PVC pipe or drain, you can clear the additional condensation with a special pan-cleaning tab. You can buy these tablets at a home improvement or hardware retailer.
If your pan includes a pump, look for 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 704-233-7363 for support.
2. AC Blows Warm Air
If your AC is on but not providing cold air, its airflow could be blocked. Or it might not have adequate refrigerant.
Your equipment’s airflow can be reduced by a blocked air filter or filthy condenser.
How to Put in a New Your Air Filter
A dusty filter can cause many troubles, such as:
- Limited comfort
- Icy refrigerant lines or evaporator coil
- Uneven cooling
- Increased energy expenses
- Making your system break down sooner
We propose installing new flat filters every four weeks, and accordion filters every three months.
If you can’t remember when you last replaced yours, turn off your unit totally and remove the filter. You can find the filter in your furnace or air pump’s blower compartment. It could also be located in an adjoining filter case or wall-mounted return air grille.
Tilt the filter up to the light. If you can’t see through it, you certainly should get a new one.
5 Tips on Cleaning Your Air Conditioning Unit
Weeds, vegetation and leaves can block your condensing unit. This can limit its airflow, impact its energy efficiency and change your comfort. Here’s a method you can follow to get your unit operating properly again.
- Shut off power totally at the breaker or outside device.
- Clear yard debris 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 carefully clean the equipment’s fins. Misshapen fins can also impact performance, so you can attempt to correct them with a blunt knife.
- Take off the upper part of your unit and pull out any leaves or grass clippings that has built up. Then wipe down the condenser fan with a damp scrap cloth.
- Use a hose nozzle to carefully remove gunk off the fins from inside the system. Don’t get liquid on the fan motor.
- Put the top back on and turn on the power.
When cooling equipment doesn’t have enough refrigerant, they’ll have difficulty removing heat and humidity from your rooms.
Here are a few signs that your unit is losing refrigerant:
- It takes an extended amount of time to lower the temperature in your rooms and you’re continually decreasing the temperature on the thermostat.
- Cooling coming through the ducts isn’t as chilled as it should be.
- You’re noticing whistling or gurgling sounds when the air conditioning works.
- Your evaporator coil is frosty on account of having trouble handling humidity.
Worried your system is seeping refrigerant? You need a certified heating and cooling service specialist to take care of the leak and replenish the proper level of refrigerant in your system. Reach us at 704-233-7363 for help.
3. AC Not Blowing Enough Air
When it appears like you’re not having adequate amounts of cold air, there’s possibly a clog or disconnection somewhere in your cooling equipment.
- The beginning step is examining your air filter. Replace it if it’s dusty.
- Then make sure the vents are clear around your house.
- If you’re still not experiencing adequate cold air, you should have your ducts inspected by a pro like Hopper Heating and Air. Your ductwork might need to be fixed or rejoined in tricky areas like your attic, basement or crawl space.
