Air Conditioner Repair Checklist
1. AC Won’t Turn On
There can be several explanations why your AC unit won’t work: an overloaded circuit breaker, wrong thermostat settings, a shut off switch or a full condensate drain pan.
Overloaded Circuit Breaker
Your system won’t run when you have a tripped breaker.
To find out if one has blown, locate your house’s main electrical panel. You can find this gray device 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.
- Locate the breaker identified “AC” and confirm it’s in the “on” spot. If it’s triggered, the breaker will be in the middle or “off” location.
- Quickly shift the lever back to the “on” location. If it instantly triggers again, don’t touch it and get in touch with us at 204-272-8128. A fuse that keeps tripping may mean your house has an electrical issue.
Incorrect Thermostat Settings
If your thermostat isn’t telling your AC to run, it won’t turn on.
The most important point is checking it’s switched to “cool” and not “heat.” Otherwise your air conditioner will probably not turn on. Or you might have warm air blowing from vents being the heat is running instead.
If you have a traditional thermostat:
- Swap out the batteries if the monitor is blank. If the readout is displaying scrambled letters, buy a new thermostat.
- Make sure the correct option is displaying. If you can’t change it, cancel it by lowering the temperature and hitting the “hold” button. This will make your AC start if scheduling is incorrect.
- Test setting the thermostat 5 degrees below the room’s temperature. Your AC won’t start if the thermostat is identical to the house’s temperature.
Once your thermostat is set correctly, you should begin getting refreshing air quickly.
If you have a smart thermostat, such as one made by Nest, Ecobee, Lux, Honeywell or Bosch, look at the manufacturer’s website for troubleshooting. If you’re still having problems, reach us at 204-272-8128 for assistance.
Your AC typically has a power-cutting lever by its outside unit. This switch is generally in a metal box hung on your residence. If your unit has recently been repaired, the lever may have accidentally been placed in the “off” setting.
Clogged Condensate Drain Pan
Condensate drain pans keep the additional condensation your system pulls from the air. This pan can be positioned either below or in your furnace or air handler.
When there’s a blockage or clogged drain, water can build up and trigger a safety control to stop your unit.
If your pan includes a PVC pipe or drain, you can drain the extra condensation with a formulated pan-cleaning tablet. You can purchase these tabs 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 could need to get a new pump. Reach us at 204-272-8128 for help.
2. AC Blows Warm Air
If your equipment is on but not delivering cold air, its airflow could be blocked. Or it may not have sufficient refrigerant.
Your unit’s airflow can be restricted by a blocked air filter or dusty condenser.
How to Put in a New Your Air Filter
A dusty filter can lead to numerous issues, including:
- Lower comfort
- Frozen refrigerant lines or evaporator coil
- Uneven cooling
- Larger electricity expenses
- Leading your system to wear out more quickly
We propose replacing flat filters every four weeks, and creased filters every three months.
If you can’t recall when you last changed yours, turn off your unit completely and take out the filter. You can spot the filter in your furnace or air pump’s blower compartment. It could also be situated in an adjoining filter holder or wall-mounted return air grille.
Tilt the filter up to the sunshine. If you can’t see any light, you should get a new one.
5 Tips on Cleaning Your AC Equipment
Weeds, grass and leaves can obstruct your condensing equipment. This may restrict its airflow, make it less energy efficient and impact your comfort. Here’s a way you can get your equipment operating well again.
- Shut off power fully at the breaker or outdoor switch.
- Clear greenery waste around the unit. Once you’ve removed larger refuse within a two-foot range, you can use a soft brush or vacuum to gingerly remove dust from the unit’s fins. Misshapen fins can also affect capability, so you can attempt to correct them with a dinner knife.
- Remove the upper grate of your unit and remove any leaves or weeds that has built up. Then wipe off the condenser fan with a damp scrap cloth.
- Use a hose nozzle to gingerly clean the fins from inside the equipment. Don’t get water on the fan motor.
- Put the top back on and turn the power back on.
When cooling units don’t have enough refrigerant, they’ll have difficulty removing heat and humidity from your residence.
Here are a few flags that your system is seeping refrigerant:
- It takes too long to cool your residence and you’re regularly decreasing the temperature on the thermostat.
- Air coming through the registers isn’t as chilled as it should be.
- You’re hearing hissing or gurgling racket when cooling is on.
- Your evaporator coil is icy as a result of having difficulty taking on warmth.
Think your system is losing refrigerant? You need a authorized heating and cooling service specialist to fix the leak and refill the right level of refrigerant in your unit. Reach us at 204-272-8128 for assistance.
3. AC Not Blowing Enough Air
When it feels like you’re not receiving enough cool air, there’s usually a clog or separation somewhere in your air conditioning equipment.
- The beginning step is checking your air filter. Replace it if it’s dusty.
- Then check the ductwork is clear around your rooms.
- If you’re still not experiencing ample cold air, you should have your duct system checked by a pro like Kirkfield Heating & Air Conditioning. Your ductwork could need to be serviced or reconnected in hard-to-reach areas like your attic, basement or crawl space.
