Your air conditioning can work for months without a problem. The air filters should be changed monthly during periods of heavy use, and you will want to pay attention to common problems when it comes to how your air conditioner is running. If you get your system serviced early in the season, this is a great step at preventing the potential for needing emergency repairs. If you notice that your system isn't getting your home cool enough, or that it continually turns on and off without bringing the temperature down, it's time to investigate further. Short cycling, thermostat issues, low refrigerant levels, and general wear and tear on your system can all lead to problems with maintaining a comfortable temperature in your home.
Short Cycling and Your Air Conditioning
Short cycling is when your system turns on and off frequently without cooling down your home all the way. This can be caused by low refrigerant levels in your system, poor airflow in the unit because of dirty air filters, or an issue with the system being too large or too small for your home. You can try changing your air filters to see if this solves the problem. If the unit is too small for your home, it may be overheating before it can cool down your home. Your air conditioning contractor will figure out a solution.
Ice On Evaporator Coils
Ice can build up on your evaporator coils, making it difficult for your air conditioner to function. This can stunt the airflow going into your unit, making your system work too hard to try and cool the home. Turn off your air conditioner and allow the ice to melt completely. This could solve your problem for the short term. Pay attention to see if ice begins to build up again. The problem could be with moisture buildup, or you could have low refrigerant levels.
When you have a whole-house air conditioning system, always check that the temperature setting is set to cool and not fan before you call your air conditioning contractor for help. Improve the cooling ability of your system by making sure the air can flow freely from room to room. Use ceiling fans to circulate air, and get your system maintained before you need to use your system every day. Get your air ducts cleaned yearly and checked for air leaks. If you have a problem, call for help and don't continue to run your air conditioner.
