During the hot summer months, air conditioners are crucial in most homes. However, broken ACs can be very discomforting and problematic for homeowners. Instead of rushing to fix it right away, inspections should be conducted first to determine what’s wrong with your unit. Testing your AC is an easy process that doesn’t require any prior engineering knowledge.
1- Check the thermostat.
2- Go outside to check the condition of the hose, the compressor, and all other parts that are exposed to outside conditions. If there is any damage, get them repaired by a professional or call for professional help.
3- Look at the inside of your air conditioner unit for any damages caused by storms or strong winds. If there are any damages, get them fixed by a professional before using the air conditioner again.
4- Use your finger to touch the insulation on all parts that are insulated for any indications of damage or water leaks.
5- Check the refrigerant level. Add refrigerant if needed, then give it some rest for 4 hours to see if the compressor starts.
6- If you added refrigerant, make sure that the next day your unit is not leaking coolant from any parts of the outside case. In addition, there should be no strange odors coming from inside your house after running the air conditioner for a while.
7- Check the resistance. Use a resistor to check the condition of the compressor and the fan motor. Check for any shorted or open parts in them before using them again.
8- If you added refrigerant, there should be no leaking from your house and the air conditioning system should not be producing any strange noises.
9- Turn on your AC system. If everything is fine, you should feel cool or cold air coming out of your outlets.
10- Check the house temperature with a thermometer to see if it’s around the same as the room temperature. The difference shouldn’t be too drastic. If you feel either hot or cold air coming out of your vent, first check for broken fan blades or blocked vents, then call for professional help.
