Air Conditioner Repair Checklist
1. AC Won’t Turn On
There can be a couple of explanations why your air conditioning system won’t cool: a blown circuit breaker, incorrect thermostat settings, a switched off switch or an overfull condensate drain pan.
Blown Circuit Breaker
Your cooling won’t run when you have a blown breaker.
To check if one has gotten overloaded, locate your house’s main electrical panel. You can locate this silver device on the wall in the basement, garage or closet.
- Confirm your hands and feet aren’t wet before you check the panel or breakers.
- Locate the breaker identified “AC” and ensure it’s in the “on” location. If it’s overloaded, the lever will be in the "off" position.
- Quickly transfer the switch back to the “on” spot. If it immediately flips again, leave it alone and reach us at 662-269-8716. A switch that keeps turning off may mean your home has an electrical problem.
Inaccurate Thermostat Settings
If your thermostat isn’t telling your AC to run, it won’t switch on.
The first part is checking it’s on “cool” and not “heat.” Otherwise your AC may not start running. You could also have hot air coming from vents because the furnace is on instead.
If you’re using a regular thermostat:
- Replace the batteries if the readout is clear. If the screen is presenting jumbled letters, buy a new thermostat.
- Ensure the proper program is on the display. If you can’t alter it, override it by lowering the temperature and pressing the “hold” button. This will make your AC start if programming is not right.
- Try setting the thermostat 5 degrees below the room’s temperature. Your AC won’t work if the thermostat is set the same as the room’s temperature.
Once your thermostat is adjusted properly, you should receive cold air fast.
If you’re using a smart thermostat, such as one manufactured by Nest, Ecobee, Lux, Honeywell or Bosch, go to the manufacturer’s website for help. If you’re still having problems, call us at 662-269-8716 for support.
Your AC probably has a shut-down switch around its outdoor unit. This switch is commonly in a metal box hung on your home. If your AC has recently been serviced, the lever may have unintentionally been turned off.
Overflowing Condensate Drain Pan
Condensate drain pans catch the extra condensation your air conditioner pulls from the air. This pan is located either under or inside your furnace or air handler.
When there’s a clog or blocked drain, water can become concentrated and trigger a safety control to turn off your equipment.
If your pan involves a PVC pipe or drain, you can drain the extra liquid with a formulated pan-cleaning tab. You can purchase these tabs at a home improvement or hardware shop.
If your pan involves a pump, look for the float switch. If the mechanism is “up” and there’s water in the pan, you could need to install a new pump. Contact us at 662-269-8716 for assistance.
2. AC Blows Warm Air
If your AC is going but not cooling, its airflow may be clogged. Or it could not have enough refrigerant.
Your equipment’s airflow can be reduced by a blocked air filter or dusty condenser.
How to Put in a New Your Air Filter
A dirty filter can create numerous problems, such as:
- Reduced cooling
- Frosted refrigerant lines or evaporator coil
- Inconsistent cooling
- Increased energy expenses
- Leading your system to stop working sooner
We recommend changing flat filters monthly, and pleated filters every three months.
If you can’t remember when you last replaced your filter, shut off your unit completely and remove the filter. You can locate the filter in your furnace or air pump’s blower compartment. It could also be located in an attached filter box or wall-mounted return air grille.
Tilt the filter up to your light fixture. If you can’t see through it, you certainly should get a new one.
4 Tips on Cleaning Your Air Conditioning Equipment
Brush, vegetation and bushes can block your condensing equipment. This could restrict its airflow, impact its energy efficiency and impact your comfort. Here’s a way you can get your unit running smoothly again.
- Shut off the electrical current fully at the breaker or outdoor switch.
- Clear yard waste around the unit. Once you’ve removed all the debris within a two-foot radius, you can use a paint brush or vacuum to slowly clean the condenser fins. Warped fins can also hurt capability.
- Use a hose nozzle to carefully clean the fins from inside the system. Be careful to avoid getting water on the fan motor.
- Turn on the power.
When cooling systems don’t have sufficient refrigerant, they’ll have difficulty removing heat and humidity from your residence.
Here are a few signs that your equipment is losing refrigerant:
- It takes a long time to refresh your residence and you’re regularly turning down the thermostat.
- Air blowing through the ducts isn’t as cold as it should be.
- You’re noticing fizzing or bubbling sounds when the AC runs.
- Your evaporator coil is iced over as a result of having an issue handling humidity.
Worried your unit is leaking refrigerant? You need a authorized heating and cooling service expert to fix the leak and restore the right measurement of refrigerant in your equipment. Call us at 662-269-8716 for support.
3. AC Not Blowing Enough Air
When it feels like you’re not having adequate amounts of chilled air, there’s probably a clog or separation within your air conditioning system.
- The initial place is looking at your air filter. Replace it if it’s dusty.
- Make sure the ductwork is open throughout your residence.
- If you’re still not experiencing sufficient cold air, you should have your ductwork checked by a specialist like Booneville Heating & Cooling LLC. Your ductwork may need to be repaired or relinked in tricky areas like your attic, basement or crawl space.
