Air Conditioner Repair Checklist
1. AC Won’t Turn On
There can be a few causes why your AC equipment won’t run: a triggered circuit breaker, wrong thermostat settings, a switched off switch or a full condensate drain pan.
Tripped Circuit Breaker
Your system won’t turn on when you have a tripped breaker.
To find out if one has gotten overloaded, go to your home’s main electrical panel. You can find this metallic fixture on the wall in the basement, garage or closet.
- Make sure your hands and feet are free of moisture before you check the panel or breakers.
- Look for the breaker marked “AC” and ensure it’s in the “on” spot. If it’s tripped, the breaker will be in the "off" position.
- Firmly shift the switch back to the “on” location. If it instantly flips again, leave it alone and get in touch with us at 800-COOLING. A fuse that keeps flipping may indicate your residence has an electrical issue.
Wrong Thermostat Settings
If your thermostat isn’t giving a sign to your AC to start, it won’t activate.
The most important point is making sure it’s switched to “cool” and not “heat.” Otherwise your AC might not turn on. You may also have hot air blowing from vents because the furnace is going instead.
If you have a regular thermostat:
- Replace the batteries if the screen is clear. If the screen is presenting garbled letters, get a new thermostat.
- Check the right option is showing. If you can’t alter it, override it by lowering the temperature and hitting the “hold” button. This will cause your AC to run if programming is incorrect.
- Try setting the thermostat 5 degrees below the space’s temperature. Your AC won’t start if the thermostat is identical to the space’s temperature.
Once your thermostat is calibrated properly, you should begin getting refreshing air fast.
If you’re using a smart thermostat, such as one manufactured by Nest, Ecobee, Lux, Honeywell or Bosch, check the manufacturer’s website for help. If you still can’t get it to work, reach us at 800-COOLING for support.
Your system probably has a shut-off switch by its outdoor unit. This lever is commonly in a metal box hung on your house. If your AC has recently been fixed, the switch may have inadvertently been turned off.
Clogged Condensate Drain Pan
Condensate drain pans hold the surplus condensation your system takes out of the air. This pan can be positioned either below or in your furnace or air handler.
When there’s an obstruction or backed up drain, water can build up and initiate a safety setting to stop your unit.
If your pan has a PVC pipe or drain, you can get rid of the surplus liquid with a formulated pan-cleaning capsule. You can buy these capsules at a home improvement or hardware retailer.
If your pan has a pump, look for the float switch. If the lever is “up” and there’s moisture in the pan, you might have to replace the pump. Contact us at 800-COOLING for support.
2. AC Blows Warm Air
If your AC is on but not delivering cold air, its airflow might be blocked. Or it could not have sufficient refrigerant.
Your equipment’s airflow can be reduced by a blocked air filter or filthy condenser.
How to Put in a New Your Air Filter
A dusty filter can cause a lot of troubles, including:
- Limited cooling
- Frosted refrigerant lines or evaporator coil
- Intermittent cooling
- Higher cooling expenses
- Making your system break down more quickly
We suggest changing flat filters every four weeks, and pleated filters every three months.
If you can’t recall when you last replaced your filter, shut off your AC completely and pull out the filter. You can find the filter in your furnace or air pump’s blower compartment. It may also be located in a connected filter case or wall-mounted return air grille.
Tilt the filter up to the sunshine. If you see a lot of dust, you need to get a new one.
4 Tips on Cleaning Your Cooling Equipment
Weeds, vegetation and leaves can block your condensing equipment. This may reduce its airflow, lower its energy efficiency and change your comfort. Here’s a method you can follow to get your system running well again.
- Switch off power fully at the breaker or outside switch.
- Clear yard waste around the unit. Once you’ve gotten rid of bigger debris within a two-foot radius, you can use a soft brush or vacuum to slowly remove dirt from the unit’s fins. Crooked fins can also hurt performance.
- Use a hose nozzle to carefully remove gunk off the fins from inside the equipment. Don’t get liquid on the fan motor.
- Turn the power back on.
Not Enough Refrigerant
When cooling systems don’t have sufficient refrigerant, they’ll struggle to remove heat and humidity from your residence.
Here are several flags that your unit is losing refrigerant:
- It takes too long to lower the temperature in your home and you’re continually decreasing the temperature on the thermostat.
- Cooling moving through the vents isn’t as chilly as it should be.
- You’re hearing hissing or burbling sounds when the air conditioning is on.
- Your evaporator coil is frozen on account of having trouble handling warmth.
Think your system is seeping refrigerant? You need a licensed heating and cooling service professional to take care of the leak and refill the correct measurement of refrigerant in your system. Get in touch with us at 800-COOLING for assistance.
3. AC Not Blowing Enough Air
When it appears like you’re not getting ample amounts of chilled air, there’s usually a clog or separation within your cooling equipment.
- The beginning place is checking your air filter. Buy a new one if it’s soiled.
- Make sure the ductwork is open across your rooms.
- If you’re still not experiencing enough cold air, you should have your ductwork examined by a professional like Brooks Heating and Air Conditioning. Your duct system might need to be fixed or hooked up again in limited space spots like your attic, basement or crawl space.
