Air Conditioner Repair Checklist
1. AC Won’t Turn On
There can be several reasons why your central AC system won’t work: a triggered circuit breaker, incorrect thermostat settings, a turned off switch or an overfull condensate drain pan.
Triggered Circuit Breaker
Your AC won’t work when you have a tripped breaker.
To see if one has gotten overloaded, find your home’s main electrical panel. You can find this gray box on the wall in the basement, garage or closet.
- Ensure your hands and feet aren’t wet before you touch the panel or breakers.
- Find the breaker marked “AC” and make sure it’s in the “on” spot. If it’s overloaded, the breaker will be in the middle of the panel or “off” spot.
- Steadily shift the lever back to the “on” location. If it instantaneously flips again, leave it alone and call us at 407-477-6319. A switch that keeps flipping could mean your residence has an electrical issue.
Incorrect Thermostat Settings
If your thermostat isn’t telling your AC to run, it won’t switch on.
The key part is checking it’s set to “cool” and not “heat.” Otherwise your AC might not switch on. Or you could receive warm air moving from vents because the heat is running instead.
If you have a digital thermostat:
- Put in new batteries if the monitor is clear. If the monitor is presenting jumbled characters, buy a new thermostat.
- Check the right program is on the display. If you can’t change it, override it by lowering the temperature and hitting the “hold” button. This will make your AC start if programming is wrong.
- Test setting the thermostat 5 degrees colder than the house’s temperature. Your AC won’t start if the thermostat matches the room’s temperature.
Once your thermostat is adjusted properly, you should receive cool air fast.
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 you still can’t get it to work, call us at 407-477-6319 for assistance.
Your cooling equipment usually has a shut-off switch near its outdoor unit. This lever is generally in a metal box hung on your residence. If your air conditioner has recently been maintained, the device may have inadvertently been put in the “off” location.
Blocked Condensate Drain Pan
Condensate drain pans keep the surplus liquid your equipment takes out of the air. This pan is located either under or in your furnace or air handler.
When there’s a clog or blocked drain, water can become concentrated and trigger a safety feature to turn off your air conditioner.
If your pan has a PVC pipe or drain, you can clear the extra liquid with a formulated pan-cleaning capsule. You can get these tabs at a home improvement or hardware shop.
If your pan includes a pump, look for the float switch. If the mechanism is “up” and there’s moisture in the pan, you might have to replace the pump. Reach us at 407-477-6319 for support.
2. AC Blows Warm Air
If your system is working but not providing cold air, its airflow might be blocked. Or it may not have enough refrigerant.
Your equipment’s airflow can be decreased by a blocked air filter or filthy condenser.
How to Put in a New Your Air Filter
A filthy filter can lead to many issues, such as:
- Limited cooling
- Frosted refrigerant lines or evaporator coil
- Uneven cooling
- Higher energy bills
- Causing your system to break down sooner
We recommend replacing flat filters once a month, and pleated filters every three months.
If you aren’t sure when you last replaced yours, shut off your unit completely 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 a connected filter box or wall-mounted return air grille.
Angle the filter up to your light fixture. If you can’t see any light, you need to get a new one.
5 Tips on Cleaning Your Air Conditioning Equipment
Weeds, vegetation and sticks can obstruct your condensing equipment. This can reduce its airflow, make it less energy efficient and affect your comfort. Here’s how you can get your unit operating properly again.
- Switch off power totally at the breaker or outside switch.
- Get rid of vegetation rubbish around the air conditioner. Once you’ve gotten rid of larger debris within a two-foot radius, you can use a paint brush or vacuum to carefully clean the condenser fins. Misshapen fins can also impact effectiveness, so you can attempt to reshape them with a blunt knife.
- Lift off the top of your unit and remove any leaves or yard waste that has collected. Then clean the condenser fan with a damp scrap cloth.
- Use a hose nozzle to slowly remove gunk off the fins from inside the equipment. Be careful to avoid getting moisture on the fan motor.
- Replace the top and restore the power.
Low Refrigerant Levels
When AC units don’t have adequate refrigerant, they’ll have to work much harder to remove heat and humidity from your home.
Here are a few indications that your unit is losing refrigerant:
- It takes a long time to lower the temperature in your home and you’re constantly turning down the thermostat.
- Cooling coming through the registers isn’t as cold as it should be.
- You’re hearing fizzing or gurgling noises when the air conditioning runs.
- Your evaporator coil is frosty due to having an issue absorbing humidity.
Worried your system is leaking refrigerant? You need a licensed heating and cooling service specialist to repair the leak and refill the correct amount of refrigerant in your system. Get in touch with us at 407-477-6319 for help.
3. AC Not Blowing Enough Air
When it seems like you’re not having enough cool air, there’s probably an obstruction or detachment inside your air conditioning unit.
- The initial stage is checking your air filter. Replace it if it’s dirty.
- Then check the ductwork is open throughout your rooms.
- If you’re still not getting enough chilled air, you should have your duct system inspected by a professional like Osceola Air, LLC. Your duct system might need to be serviced or relinked in tricky spots like your attic, basement or crawl space.
