1. AC Won’t Turn On
There can be several explanations why your air conditioning won’t work: a triggered circuit breaker, incorrect thermostat settings, a turned off switch or an overflowing condensate drain pan.
Tripped Circuit Breaker
Your air conditioner won’t turn on when you have an overloaded breaker.
To see if one has tripped, find your home’s main electrical panel. You can spot this gray fixture on the wall in the basement, garage or closet.
- Confirm your hands and feet are dry before you check the panel or breakers.
- Find the breaker marked “AC” and confirm it’s in the “on” position. If it’s tripped, the switch will be in the middle of the panel or “off” spot.
- Firmly shift the breaker back to the “on” location. If it instantaneously trips again, leave it alone and get in touch with us at 256-574-1300. A breaker that keeps flipping could signal your residence has an electrical problem.
Wrong Thermostat Settings
If your thermostat isn’t signaling your system to start, it won’t turn on.
The most important part is checking it’s on “cool” and not “heat.” Otherwise your AC may not switch on. Or you could receive hot air moving from vents since the heat is going instead.
If you rely on a regular thermostat:
- Put in new batteries if the screen is clear. If the monitor is displaying jumbled characters, buy a new thermostat.
- Make sure the right mode is displaying. If you can’t update it, reverse it by lowering the temperature and pressing the “hold” button. This will cause your AC to run if programming is not right.
- Try setting the thermostat 5 degrees cooler than the space’s temperature. Your AC won’t cool if the thermostat matches the space’s temperature.
Once your thermostat is adjusted properly, you should start getting chilled air quickly.
If you rely on a smart thermostat, like one manufactured by Nest, Ecobee, Lux, Honeywell or Bosch, check the manufacturer’s website for help. If you’re still having problems, contact us at 256-574-1300 for help.
Your AC usually has a shut-off lever near its outdoor unit. This device is generally in a metal box mounted on your home. If your equipment has recently been maintained, the switch may have inadvertently been put in the “off” position.
Clogged Condensate Drain Pan
Condensate drain pans keep the extra condensation your system takes out of the air. This pan can be situated either beneath or within your furnace or air handler.
When there’s a clog or backed up drain, water can accumulate and trigger a safety setting to turn off your equipment.
If your pan involves a PVC pipe or drain, you can drain the additional condensation with a special pan-cleaning capsule. You can buy these capsules at a home improvement or hardware store.
If your pan has a pump, look for the float switch. If the switch is “up” and there’s water in the pan, you might have to get a new pump. Call us at 256-574-1300 for support.
2. AC Blows Warm Air
If your air conditioner is running but not cooling, its airflow might be obstructed. Or it could not have enough refrigerant.
Your unit’s airflow can be limited by a plugged air filter or filthy condenser.
How to Put in a New Your Air Filter
A dirty filter can create many problems, such as:
- Limited comfort
- Icy refrigerant lines or evaporator coil
- Inconsistent cooling
- Larger cooling expenses
- Leading your system to wear out more quickly
We recommend replacing flat filters once a month, and creased filters every three months.
If you can’t remember when you last replaced yours, turn off your equipment totally and pull out the filter. You can find the filter in your furnace or air pump’s blower compartment. It could also be located in an attached filter case or wall-mounted return air grille.
Angle the filter up to the sunshine. If you see a lot of dust, you certainly should buy a new filter.
5 Steps to Cleaning Your Cooling Unit
Greenery, plants and leaves can get in the way of your condensing unit. This can limit its airflow, impact its energy efficiency and change your comfort. Here’s a way you can get your unit running smoothly again.
- Shut off the electrical current completely at the breaker or outdoor switch.
- Clear yard waste around the air conditioner. Once you’ve cleared larger clutter within a two-foot radius, you can use a soft brush or vacuum to slowly clean the condenser fins. Misshapen fins can also hurt capability, so you can attempt to correct them with a small knife.
- Remove the upper part of your system and pull out any leaves or sticks that has collected. 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 equipment. Don’t get water on the fan motor.
- Install the top again and turn the power back on.
Low Refrigerant Levels
When cooling equipment doesn’t have enough refrigerant, they’ll have difficulty removing heat and humidity from your home.
Here are a few symptoms that your unit is losing refrigerant:
- It takes too long to refresh your residence and you’re constantly decreasing the temperature on the thermostat.
- Air conditioning coming through the ducts isn’t as cold as it should be.
- You’re experiencing whistling or burbling racket when the AC runs.
- Your evaporator coil is frosted as a result of having an issue absorbing warmth.
Worried your system is losing refrigerant? You need a qualified heating and cooling service specialist to take care of the leak and refill the right level of refrigerant in your unit. Call us at 256-574-1300 for help.
3. AC Not Blowing Enough Air
When it appears like you’re not getting enough chilled air, there’s probably a clog or disconnection within your air conditioning equipment.
- The initial stage is checking your air filter. Replace it if it’s dusty.
- Then check the registers are open around your house.
- If you’re still not getting sufficient chilly air, you should have your ducts examined by a specialist like Southern Heating & Cooling Inc.. Your duct system might need to be fixed or relinked in tricky locations like your attic, basement or crawl space.
