1. AC Won’t Turn On
There can be several causes why your AC unit won’t cool: a tripped circuit breaker, incorrect thermostat settings, a turned off switch or an overfull condensate drain pan.
Overloaded Circuit Breaker
Your AC won’t work when you have a blown breaker.
To determine if one has gotten overloaded, go to your house’s main electrical panel. You can locate this gray device on the wall in the basement, garage or closet.
- Ensure your hands and feet are free of moisture before you work on the panel or breakers.
- Find the breaker labeled “AC” and confirm it’s in the “on” location. If it’s overloaded, the switch will be in the in between or “off” location.
- Firmly move the lever back to the “on” spot. If it instantly trips again, leave it alone and get in touch with us at 706-695-7492. A fuse that keeps tripping could signal your residence has an electrical problem.
Inaccurate Thermostat Settings
If your thermostat isn’t giving a sign to your air conditioner to start, it won’t switch on.
The main part is checking it’s switched to “cool” and not “heat.” Otherwise your air conditioning will probably not turn on. Or you might receive warm air moving from vents because the heat is on instead.
If you’re using a traditional thermostat:
- Put in new batteries if the readout is blank. If the monitor is presenting scrambled numbers, buy a new thermostat.
- Check the right option is displaying. If you can’t change it, override it by lowering the temperature and pushing the “hold” button. This will cause your AC to run if programming is wrong.
- Try setting the thermostat 5 degrees below the space’s temperature. Your AC won’t cool if the thermostat is set the same as the space’s temperature.
Once your thermostat is adjusted properly, you should begin getting refreshing air promptly.
If you’re using a smart thermostat, such as one made by Nest, Ecobee, Lux, Honeywell or Bosch, look at the manufacturer’s website for troubleshooting. If you still can’t get it to work, contact us at 706-695-7492 for assistance.
Your system probably has a power-cutting switch near its outdoor unit. This device is generally in a metal box hung on your home. If your AC has recently been fixed, the lever may have accidentally been positioned in the “off” position.
Blocked Condensate Drain Pan
Condensate drain pans hold the surplus water your system takes out of the air. This pan is located either below or inside your furnace or air handler.
When there’s a blockage or blocked drain, water can become concentrated and initiate a safety setting to turn off your unit.
If your pan includes a PVC pipe or drain, you can clear the additional liquid with a custom pan-cleaning capsule. You can buy these tablets at a home improvement or hardware shop.
If your pan includes a pump, locate the float switch. If the lever is “up” and there’s water in the pan, you may need to install a new pump. Contact us at 706-695-7492 for help.
2. AC Blows Warm Air
If your AC is on but not cooling, its airflow may be clogged. Or it may not have sufficient refrigerant.
Your unit’s airflow can be reduced by a blocked air filter or dirty condenser.
How to Replace Your Air Filter
A dusty filter can cause countless troubles, like:
- Reduced comfort
- Frosted refrigerant lines or evaporator coil
- Inconsistent cooling
- Higher electricity bills
- Leading your system to wear out sooner
We suggest changing flat filters once a month, and accordion filters every three months.
If you can’t remember when you last installed a new one, switch off your equipment fully and remove the filter. You can spot the filter in your furnace or air pump’s blower compartment. It might also be situated in a connected filter box or wall-mounted return air grille.
Tilt the filter up to the sunshine. If you see a lot of dust, you certainly should get a new one.
5 Tips on Cleaning Your AC Unit
Weeds, grass and leaves can block your condensing system. This could restrict its airflow, impact its energy efficiency and affect your comfort. Here’s a way you can get your unit working well again.
- Shut off electricity fully at the breaker or external lever.
- Remove plant waste around the AC. Once you’ve removed all the clutter within a two-foot area, you can use a paint brush or vacuum to carefully remove dust from the equipment’s fins. Crooked fins can also affect performance, so you can attempt to straighten them with a blunt knife.
- Take off the upper part of your AC and remove any leaves or yard waste that has collected. Then wipe off the condenser fan with a moist rag.
- Use a hose nozzle to gingerly clean the fins from inside the equipment. Make sure to avoid getting moisture on the fan motor.
- Replace the top and turn on the power.
Not Enough Refrigerant
When air conditioning equipment doesn’t have adequate refrigerant, they’ll struggle to remove heat and humidity from your space.
Here are a couple of signs that your unit is losing refrigerant:
- It takes a long time to refresh your space and you’re continually turning down the thermostat.
- Air moving through the registers isn’t as cold as it should be.
- You’re noticing fizzing or gurgling racket when the AC runs.
- Your evaporator coil is frozen due to having difficulty absorbing heat.
Think your unit is losing refrigerant? You need a licensed heating and cooling service specialist to take care of the leak and replenish the right measurement of refrigerant in your unit. Reach us at 706-695-7492 for help.
3. AC Not Blowing Enough Air
When it feels like you’re not having ample amounts of chilled air, there’s possibly a clog or separation somewhere in your air conditioning system.
- The initial stage is examining your air filter. Replace it if it’s soiled.
- Then ensure the ductwork is clear across your residence.
- If you’re still not experiencing enough cold air, you should have your ductwork checked by a professional like True Temp Heating & Air Inc. Your duct system might need to be fixed or rejoined in hard-to-reach areas like your attic, basement or crawl space.
