Air Conditioner Repair Checklist
1. AC Won’t Turn On
There can be several causes why your air conditioner won’t start: an overloaded circuit breaker, incorrect thermostat settings, a switched off switch or an overfull condensate drain pan.
Triggered Circuit Breaker
Your system won’t run when you have a tripped breaker.
To see if one has tripped, find your residence’s main electrical panel. You can locate this gray fixture on the wall in the basement, garage or closet.
- Confirm your hands and feet are free of moisture before you check the panel or breakers.
- Look for the breaker marked “AC” and confirm it’s in the “on” spot. If it’s tripped, the lever will be in the "off" position.
- Firmly transfer the lever back to the “on” location. If it instantly triggers again, don’t touch it and contact us at 317-406-5783. A fuse that keeps tripping could mean your residence has electrical trouble.
Wrong Thermostat Settings
If your thermostat isn’t giving a sign to your system to start, it won’t turn on.
The most important point is making sure it’s set to “cool” and not “heat.” Otherwise your AC might not switch on. You may also get hot air moving from vents since the heater is going instead.
If you have a regular thermostat:
- Replace the batteries if the readout is empty. If the monitor is showing jumbled letters, get a new thermostat.
- Check the correct option is on the display. If you can’t update it, override it by decreasing the temperature and pressing the “hold” button. This will force your AC to work if scheduling is wrong.
- Attempt to set the thermostat 5 degrees colder than the space’s temperature. Your AC won’t start if the thermostat is identical to the space’s temperature.
Once your thermostat is set properly, you should begin getting chilled air promptly.
If you have a smart thermostat, including ones made by Nest, Ecobee, Lux, Honeywell or Bosch, look at the manufacturer’s website for help. If you still can’t get it to work, reach us at 317-406-5783 for help.
Your system usually has a power-cutting device near its outside unit. This device is commonly in a metal box attached to your residence. If your equipment has recently been worked on, the switch may have unintentionally been turned off.
Clogged Condensate Drain Pan
Condensate drain pans catch the additional liquid your equipment pulls from the air. This pan can be situated either under or in your furnace or air handler.
When there’s an obstruction or clogged drain, water can become concentrated and initiate a safety feature to switch off your air conditioner.
If your pan includes a PVC pipe or drain, you can get rid of the surplus condensation with a formulated pan-cleaning capsule. You can get these capsules at a home improvement or hardware store.
If your pan includes a pump, look for the float switch. If the switch is “up” and there’s moisture in the pan, you may need to install a new pump. Contact us at 317-406-5783 for assistance.
2. AC Blows Warm Air
If your air conditioner is running but not cooling, its airflow may be congested. Or it might not have enough refrigerant.
Your system’s airflow can be decreased by a clogged air filter or filthy condenser.
How to Put in a New Your Air Filter
A dirty filter can create numerous troubles, including:
- Reduced comfort
- Frozen refrigerant lines or evaporator coil
- Intermittent cooling
- Increased energy bills
- Causing your system to wear out sooner
We suggest changing flat filters monthly, and pleated filters every three months.
If you can’t remember when you last replaced your filter, switch off your system totally 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 holder or wall-mounted return air grille.
Angle the filter up to your light fixture. If you can’t see any light, you need to replace it.
How to Clean Your Cooling Unit
Weeds, plants and shrubbery can get in the way of your condensing system. This could limit its airflow, make it less energy efficient and change your comfort. Here’s a method you can follow to get your equipment running properly again.
- Switch off the electrical current totally at the breaker or external lever.
- Remove greenery rubbish around the equipment. Once you’ve gotten rid of bigger clutter within a two-foot range, you can use a paint brush or vacuum to gingerly remove dust from the equipment’s fins. Distorted fins can also hurt effectiveness.
- Use a hose nozzle to slowly take off dirt on the fins from inside the unit. Make sure to avoid getting moisture on the fan motor.
- Turn the power back on.
When AC units don’t have sufficient refrigerant, they’ll have difficulty removing heat and humidity from your rooms.
Here are a few symptoms that your unit is losing refrigerant:
- It takes an extended amount of time to lower the temperature in your home and you’re regularly decreasing the temperature on the thermostat.
- Air moving through the registers isn’t as chilled as it should be.
- You’re hearing hissing or bubbling sounds when the AC works.
- Your evaporator coil is frosty because it’s having an issue absorbing warmth.
Think your system is seeping refrigerant? You need a certified heating and cooling service expert to repair the leak and refill the right level of refrigerant in your unit. Get in touch with us at 317-406-5783 for support.
3. AC Not Blowing Enough Air
When it feels like you’re not having ample amounts of cold air, there’s likely an obstruction or detachment inside your AC system.
- The initial stage is checking your air filter. Replace it if it’s dusty.
- Make sure the vents are open across your house.
- If you’re still not experiencing sufficient cold air, you should have your duct system inspected by a professional like Winters Heating and Cooling. Your ducts might need to be repaired or hooked up again in tricky spots like your attic, basement or crawl space.
